If such a charmap is synthesized, it is placed at the first position of the charmap array.</p> -<p>All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, <code>FT_ENCODING_NONE</code> is used.</p> -<p><code>FT_ENCODING_NONE</code> is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to <code>FT_ENCODING_UNICODE</code>). Use <code><a href="ft2-bdf_fonts.html#ft_get_bdf_charset_id">FT_Get_BDF_Charset_ID</a></code> to find out which encoding is really present. If, for example, the <code>cs_registry</code> field is ‘KOI8’ and the <code>cs_encoding</code> field is ‘R’, the font is encoded in KOI8-R.</p> -<p><code>FT_ENCODING_NONE</code> is always set (with a single exception) by the winfonts driver.

For example, <code><a href="ft2-winfnt_fonts.html#ft_winfnt_id_xxx">FT_WinFNT_ID_CP1251</a></code> (204) means Windows code page 1251 (for Russian).</p> -<p><code>FT_ENCODING_NONE</code> is set if <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code> and <code>encoding_id</code> is not <code>TT_MAC_ID_ROMAN</code> (otherwise it is set to <code>FT_ENCODING_APPLE_ROMAN</code>).</p> -<p>If <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code>, use the function <code><a href="ft2-truetype_tables.html#ft_get_cmap_language_id">FT_Get_CMap_Language_ID</a></code> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants.

If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p> -<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p> -<p>This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness – 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or ‘dirt’ around it. The situation is especially ugly for diagonal stems like in ‘w’ glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p> -<p>The blending function for placing text over a background is -<div class="highlight"><pre><span></span><code> dst = alpha * src + (1 - alpha) * dst , -</code></pre></div></p> -<p>which is known as the OVER operator.</p> -<p>To correctly composite an anti-aliased pixel of a glyph onto a surface,</p> -<ol> -<li> -<p>take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p> -</li> -<li> -<p>use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p> -</li> -<li> -<p>apply inverse gamma to the blended pixel and write it back to the image.</p> -</li> -</ol> -<p>Internal testing at Adobe found that a target inverse gamma of 1.8 for step 3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p> -<p>This process can cost performance. There is an approximation that does not need to know about the background color; see <a href="https://bel.fi/alankila/lcd/">https://bel.fi/alankila/lcd/</a> and <a href="https://bel.fi/alankila/lcd/alpcor.html">https://bel.fi/alankila/lcd/alpcor.html</a> for details.</p> -<p><strong>ATTENTION</strong>: Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section ‘<a href="ft2-lcd_rendering.html#lcd_rendering">Subpixel Rendering</a>’.

Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits.</p> -<hr> - -<h2 id="ft_subglyph_flag_xxx">FT_SUBGLYPH_FLAG_XXX<a class="headerlink" href="#ft_subglyph_flag_xxx" title="Permanent link">¶</a></h2> -<p>Defined in FT_FREETYPE_H (freetype/freetype.h).</p> -<div class = "codehilite"><pre><code>#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_args_are_words">FT_SUBGLYPH_FLAG_ARGS_ARE_WORDS</a> 1 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_args_are_xy_values">FT_SUBGLYPH_FLAG_ARGS_ARE_XY_VALUES</a> 2 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_round_xy_to_grid">FT_SUBGLYPH_FLAG_ROUND_XY_TO_GRID</a> 4 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_scale">FT_SUBGLYPH_FLAG_SCALE</a> 8 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_xy_scale">FT_SUBGLYPH_FLAG_XY_SCALE</a> 0x40 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_2x2">FT_SUBGLYPH_FLAG_2X2</a> 0x80 -#<span class="keyword">define</span> <a href="ft2-base_interface.html#ft_subglyph_flag_use_my_metrics">FT_SUBGLYPH_FLAG_USE_MY_METRICS</a> 0x200 -</code></pre></div> - -<p>A list of constants describing subglyphs.

On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale anti-aliasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p> <p>2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of ⅓ pixels) is less of a problem.</p> <p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called ‘blue zones’) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p> -<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p> +<p>Hstems (that is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone.

If such a charmap is synthesized, it is placed at the first position of the charmap array.</p> +<p>All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, <code>FT_ENCODING_NONE</code> is used.</p> +<p><code>FT_ENCODING_NONE</code> is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to <code>FT_ENCODING_UNICODE</code>). Use <code><a href="ft2-bdf_fonts.html#ft_get_bdf_charset_id">FT_Get_BDF_Charset_ID</a></code> to find out which encoding is really present. If, for example, the <code>cs_registry</code> field is ‘KOI8’ and the <code>cs_encoding</code> field is ‘R’, the font is encoded in KOI8-R.</p> +<p><code>FT_ENCODING_NONE</code> is always set (with a single exception) by the winfonts driver. Use <code><a href="ft2-winfnt_fonts.html#ft_get_winfnt_header">FT_Get_WinFNT_Header</a></code> and examine the <code>charset</code> field of the <code><a href="ft2-winfnt_fonts.html#ft_winfnt_headerrec">FT_WinFNT_HeaderRec</a></code> structure to find out which encoding is really present. For example, <code><a href="ft2-winfnt_fonts.html#ft_winfnt_id_xxx">FT_WinFNT_ID_CP1251</a></code> (204) means Windows code page 1251 (for Russian).</p> +<p><code>FT_ENCODING_NONE</code> is set if <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code> and <code>encoding_id</code> is not <code>TT_MAC_ID_ROMAN</code> (otherwise it is set to <code>FT_ENCODING_APPLE_ROMAN</code>).</p> +<p>If <code>platform_id</code> is <code><a href="ft2-truetype_tables.html#tt_platform_xxx">TT_PLATFORM_MACINTOSH</a></code>, use the function <code><a href="ft2-truetype_tables.html#ft_get_cmap_language_id">FT_Get_CMap_Language_ID</a></code> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See</p> +<p><a href="https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt">https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt</a></p> +<p>to get an idea how to do that. Basically, if the language ID is 0, don't use it, otherwise subtract 1 from the language ID. Then examine <code>encoding_id</code>. If, for example, <code>encoding_id</code> is <code>TT_MAC_ID_ROMAN</code> and the language ID (minus 1) is <code>TT_MAC_LANGID_GREEK</code>, it is the Greek encoding, not Roman. <code>TT_MAC_ID_ARABIC</code> with <code>TT_MAC_LANGID_FARSI</code> means the Farsi variant of the Arabic encoding.</p> +<hr> + +<h2 id="ft_enc_tag">FT_ENC_TAG<a class="headerlink" href="#ft_enc_tag" title="Permanent link">¶</a></h2> +<p>Defined in FT_FREETYPE_H (freetype/freetype.h).</p> +<div class = "codehilite"><pre><code>#<span class="keyword">ifndef</span> <b>FT_ENC_TAG</b> + +#<span class="keyword">define</span> <b>FT_ENC_TAG</b>( value, a, b, c, d ) \ + value = ( ( FT_STATIC_BYTE_CAST( <a href="ft2-basic_types.html#ft_uint32">FT_UInt32</a>, a ) << 24 ) | \ + ( FT_STATIC_BYTE_CAST( <a href="ft2-basic_types.html#ft_uint32">FT_UInt32</a>, b ) << 16 ) | \ + ( FT_STATIC_BYTE_CAST( <a href="ft2-basic_types.html#ft_uint32">FT_UInt32</a>, c ) << 8 ) | \ + FT_STATIC_BYTE_CAST( <a href="ft2-basic_types.html#ft_uint32">FT_UInt32</a>, d ) ) + +#<span class="keyword">endif</span> /* <b>FT_ENC_TAG</b> */ +</code></pre></div> + +<p>This macro converts four-letter tags into an unsigned long.

If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p> +<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p> +<p>This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness – 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or ‘dirt’ around it. The situation is especially ugly for diagonal stems like in ‘w’ glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p> +<p>The blending function for placing text over a background is +<div class="highlight"><pre><span></span><code> dst = alpha * src + (1 - alpha) * dst , +</code></pre></div></p> +<p>which is known as the OVER operator.</p> +<p>To correctly composite an anti-aliased pixel of a glyph onto a surface,</p> +<ol> +<li> +<p>take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p> +</li> +<li> +<p>use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p> +</li> +<li> +<p>apply inverse gamma to the blended pixel and write it back to the image.</p> +</li> +</ol> +<p>Internal testing at Adobe found that a target inverse gamma of 1.8 for step 3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p> +<p>This process can cost performance.

FT_Library \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_LibraryRec_ * FT_Library ; A handle to a FreeType library instance. Each \u2018library\u2019 is completely independent from the others; it is the \u2018root\u2019 of a set of objects like fonts, faces, sizes, etc. It also embeds a memory manager (see FT_Memory ), as well as a scan-line converter object (see FT_Raster ). [Since 2.5.6] In multi-threaded applications it is easiest to use one FT_Library object per thread. In case this is too cumbersome, a single FT_Library object across threads is possible also, as long as a mutex lock is used around FT_New_Face and FT_Done_Face . note Library objects are normally created by FT_Init_FreeType , and destroyed with FT_Done_FreeType . If you need reference-counting (cf. FT_Reference_Library ), use FT_New_Library and FT_Done_Library . FT_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_FaceRec_* FT_Face ; A handle to a typographic face object. A face object models a given typeface, in a given style. note A face object also owns a single FT_GlyphSlot object, as well as one or more FT_Size objects. Use FT_New_Face or FT_Open_Face to create a new face object from a given filepath or a custom input stream. Use FT_Done_Face to destroy it (along with its slot and sizes). An FT_Face object can only be safely used from one thread at a time. Similarly, creation and destruction of FT_Face with the same FT_Library object can only be done from one thread at a time. On the other hand, functions like FT_Load_Glyph and its siblings are thread-safe and do not need the lock to be held as long as the same FT_Face object is not used from multiple threads at the same time. also See FT_FaceRec for the publicly accessible fields of a given face object. FT_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_SizeRec_* FT_Size ; A handle to an object that models a face scaled to a given character size. note An FT_Face has one active FT_Size object that is used by functions like FT_Load_Glyph to determine the scaling transformation that in turn is used to load and hint glyphs and metrics. A newly created FT_Size object contains only meaningless zero values. You must use FT_Set_Char_Size , FT_Set_Pixel_Sizes , FT_Request_Size or even FT_Select_Size to change the content (i.e., the scaling values) of the active FT_Size . Otherwise, the scaling and hinting will not be performed. You can use FT_New_Size to create additional size objects for a given FT_Face , but they won't be used by other functions until you activate it through FT_Activate_Size . Only one size can be activated at any given time per face. also See FT_SizeRec for the publicly accessible fields of a given size object. FT_GlyphSlot \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_GlyphSlotRec_* FT_GlyphSlot ; A handle to a given \u2018glyph slot\u2019. A slot is a container that can hold any of the glyphs contained in its parent face. In other words, each time you call FT_Load_Glyph or FT_Load_Char , the slot's content is erased by the new glyph data, i.e., the glyph's metrics, its image (bitmap or outline), and other control information. also See FT_GlyphSlotRec for the publicly accessible glyph fields. FT_CharMap \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_CharMapRec_* FT_CharMap ; A handle to a character map (usually abbreviated to \u2018charmap\u2019). A charmap is used to translate character codes in a given encoding into glyph indexes for its parent's face. Some font formats may provide several charmaps per font. Each face object owns zero or more charmaps, but only one of them can be \u2018active\u2019, providing the data used by FT_Get_Char_Index or FT_Load_Char . The list of available charmaps in a face is available through the face->num_charmaps and face->charmaps fields of FT_FaceRec . The currently active charmap is available as face->charmap . You should call FT_Set_Charmap to change it. note When a new face is created (either through FT_New_Face or FT_Open_Face ), the library looks for a Unicode charmap within the list and automatically activates it. If there is no Unicode charmap, FreeType doesn't set an \u2018active\u2019 charmap. also See FT_CharMapRec for the publicly accessible fields of a given character map. FT_Encoding \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Encoding_ { FT_ENC_TAG ( FT_ENCODING_NONE , 0, 0, 0, 0 ), FT_ENC_TAG ( FT_ENCODING_MS_SYMBOL , 's', 'y', 'm', 'b' ), FT_ENC_TAG ( FT_ENCODING_UNICODE , 'u', 'n', 'i', 'c' ), FT_ENC_TAG ( FT_ENCODING_SJIS , 's', 'j', 'i', 's' ), FT_ENC_TAG ( FT_ENCODING_PRC , 'g', 'b', ' ', ' ' ), FT_ENC_TAG ( FT_ENCODING_BIG5 , 'b', 'i', 'g', '5' ), FT_ENC_TAG ( FT_ENCODING_WANSUNG , 'w', 'a', 'n', 's' ), FT_ENC_TAG ( FT_ENCODING_JOHAB , 'j', 'o', 'h', 'a' ), /* for backward compatibility */ FT_ENCODING_GB2312 = FT_ENCODING_PRC , FT_ENCODING_MS_SJIS = FT_ENCODING_SJIS , FT_ENCODING_MS_GB2312 = FT_ENCODING_PRC , FT_ENCODING_MS_BIG5 = FT_ENCODING_BIG5 , FT_ENCODING_MS_WANSUNG = FT_ENCODING_WANSUNG , FT_ENCODING_MS_JOHAB = FT_ENCODING_JOHAB , FT_ENC_TAG ( FT_ENCODING_ADOBE_STANDARD , 'A', 'D', 'O', 'B' ), FT_ENC_TAG ( FT_ENCODING_ADOBE_EXPERT , 'A', 'D', 'B', 'E' ), FT_ENC_TAG ( FT_ENCODING_ADOBE_CUSTOM , 'A', 'D', 'B', 'C' ), FT_ENC_TAG ( FT_ENCODING_ADOBE_LATIN_1 , 'l', 'a', 't', '1' ), FT_ENC_TAG ( FT_ENCODING_OLD_LATIN_2 , 'l', 'a', 't', '2' ), FT_ENC_TAG ( FT_ENCODING_APPLE_ROMAN , 'a', 'r', 'm', 'n' ) } FT_Encoding ; /* these constants are deprecated; use the corresponding ` FT_Encoding ` */ /* values instead */ # define ft_encoding_none FT_ENCODING_NONE # define ft_encoding_unicode FT_ENCODING_UNICODE # define ft_encoding_symbol FT_ENCODING_MS_SYMBOL # define ft_encoding_latin_1 FT_ENCODING_ADOBE_LATIN_1 # define ft_encoding_latin_2 FT_ENCODING_OLD_LATIN_2 # define ft_encoding_sjis FT_ENCODING_SJIS # define ft_encoding_gb2312 FT_ENCODING_PRC # define ft_encoding_big5 FT_ENCODING_BIG5 # define ft_encoding_wansung FT_ENCODING_WANSUNG # define ft_encoding_johab FT_ENCODING_JOHAB # define ft_encoding_adobe_standard FT_ENCODING_ADOBE_STANDARD # define ft_encoding_adobe_expert FT_ENCODING_ADOBE_EXPERT # define ft_encoding_adobe_custom FT_ENCODING_ADOBE_CUSTOM # define ft_encoding_apple_roman FT_ENCODING_APPLE_ROMAN An enumeration to specify character sets supported by charmaps. Used in the FT_Select_Charmap API function. note Despite the name, this enumeration lists specific character repertoires (i.e., charsets), and not text encoding methods (e.g., UTF-8, UTF-16, etc.). Other encodings might be defined in the future. values FT_ENCODING_NONE The encoding value 0 is reserved for all formats except BDF, PCF, and Windows FNT; see below for more information. FT_ENCODING_UNICODE The Unicode character set. This value covers all versions of the Unicode repertoire, including ASCII and Latin-1. Most fonts include a Unicode charmap, but not all of them. For example, if you want to access Unicode value U+1F028 (and the font contains it), use value 0x1F028 as the input value for FT_Get_Char_Index . FT_ENCODING_MS_SYMBOL Microsoft Symbol encoding, used to encode mathematical symbols and wingdings. For more information, see \u2018 https://www.microsoft.com/typography/otspec/recom.htm#non-standard-symbol-fonts \u2019, \u2018 http://www.kostis.net/charsets/symbol.htm \u2019, and \u2018 http://www.kostis.net/charsets/wingding.htm \u2019. This encoding uses character codes from the PUA (Private Unicode Area) in the range U+F020-U+F0FF. FT_ENCODING_SJIS Shift JIS encoding for Japanese. More info at \u2018 https://en.wikipedia.org/wiki/Shift_JIS \u2019. See note on multi-byte encodings below. FT_ENCODING_PRC Corresponds to encoding systems mainly for Simplified Chinese as used in People's Republic of China (PRC). The encoding layout is based on GB 2312 and its supersets GBK and GB 18030. FT_ENCODING_BIG5 Corresponds to an encoding system for Traditional Chinese as used in Taiwan and Hong Kong. FT_ENCODING_WANSUNG Corresponds to the Korean encoding system known as Extended Wansung (MS Windows code page 949). For more information see \u2018 https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit949.txt \u2019. FT_ENCODING_JOHAB The Korean standard character set (KS C 5601-1992), which corresponds to MS Windows code page 1361. This character set includes all possible Hangul character combinations. FT_ENCODING_ADOBE_LATIN_1 Corresponds to a Latin-1 encoding as defined in a Type 1 PostScript font. It is limited to 256 character codes. FT_ENCODING_ADOBE_STANDARD Adobe Standard encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes. FT_ENCODING_ADOBE_EXPERT Adobe Expert encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes. FT_ENCODING_ADOBE_CUSTOM Corresponds to a custom encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes. FT_ENCODING_APPLE_ROMAN Apple roman encoding. Many TrueType and OpenType fonts contain a charmap for this 8-bit encoding, since older versions of Mac OS are able to use it. FT_ENCODING_OLD_LATIN_2 This value is deprecated and was neither used nor reported by FreeType. Don't use or test for it. FT_ENCODING_MS_SJIS Same as FT_ENCODING_SJIS. Deprecated. FT_ENCODING_MS_GB2312 Same as FT_ENCODING_PRC. Deprecated. FT_ENCODING_MS_BIG5 Same as FT_ENCODING_BIG5. Deprecated. FT_ENCODING_MS_WANSUNG Same as FT_ENCODING_WANSUNG. Deprecated. FT_ENCODING_MS_JOHAB Same as FT_ENCODING_JOHAB. Deprecated. note When loading a font, FreeType makes a Unicode charmap active if possible (either if the font provides such a charmap, or if FreeType can synthesize one from PostScript glyph name dictionaries; in either case, the charmap is tagged with FT_ENCODING_UNICODE ). If such a charmap is synthesized, it is placed at the first position of the charmap array. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, FT_ENCODING_NONE is used. FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE ). Use FT_Get_BDF_Charset_ID to find out which encoding is really present. If, for example, the cs_registry field is \u2018KOI8\u2019 and the cs_encoding field is \u2018R\u2019, the font is encoded in KOI8-R. FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver. Use FT_Get_WinFNT_Header and examine the charset field of the FT_WinFNT_HeaderRec structure to find out which encoding is really present. For example, FT_WinFNT_ID_CP1251 (204) means Windows code page 1251 (for Russian). FT_ENCODING_NONE is set if platform_id is TT_PLATFORM_MACINTOSH and encoding_id is not TT_MAC_ID_ROMAN (otherwise it is set to FT_ENCODING_APPLE_ROMAN ). If platform_id is TT_PLATFORM_MACINTOSH , use the function FT_Get_CMap_Language_ID to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt to get an idea how to do that. Basically, if the language ID is 0, don't use it, otherwise subtract 1 from the language ID. Then examine encoding_id . If, for example, encoding_id is TT_MAC_ID_ROMAN and the language ID (minus 1) is TT_MAC_LANGID_GREEK , it is the Greek encoding, not Roman. TT_MAC_ID_ARABIC with TT_MAC_LANGID_FARSI means the Farsi variant of the Arabic encoding. FT_ENC_TAG \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # ifndef FT_ENC_TAG # define FT_ENC_TAG ( value, a, b, c, d ) \\ value = ( ( FT_STATIC_BYTE_CAST( FT_UInt32 , a ) << 24 ) | \\ ( FT_STATIC_BYTE_CAST( FT_UInt32 , b ) << 16 ) | \\ ( FT_STATIC_BYTE_CAST( FT_UInt32 , c ) << 8 ) | \\ FT_STATIC_BYTE_CAST( FT_UInt32 , d ) ) # endif /* FT_ENC_TAG */ This macro converts four-letter tags into an unsigned long. It is used to define \u2018encoding\u2019 identifiers (see FT_Encoding ). note Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this: #define FT_ENC_TAG( value, a, b, c, d ) value to get a simple enumeration without assigning special numbers. FT_FaceRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_FaceRec_ { FT_Long num_faces; FT_Long face_index; FT_Long face_flags; FT_Long style_flags; FT_Long num_glyphs; FT_String * family_name; FT_String * style_name; FT_Int num_fixed_sizes; FT_Bitmap_Size * available_sizes; FT_Int num_charmaps; FT_CharMap * charmaps; FT_Generic generic; /*# The following member variables (down to `underline_thickness`) */ /*# are only relevant to scalable outlines; cf. @ FT_Bitmap_Size */ /*# for bitmap fonts. */ FT_BBox bbox; FT_UShort units_per_EM; FT_Short ascender; FT_Short descender; FT_Short height; FT_Short max_advance_width; FT_Short max_advance_height; FT_Short underline_position; FT_Short underline_thickness; FT_GlyphSlot glyph; FT_Size size; FT_CharMap charmap; /*@private begin */ FT_Driver driver; FT_Memory memory; FT_Stream stream; FT_ListRec sizes_list; FT_Generic autohint; /* face-specific auto-hinter data */ void * extensions; /* unused */ FT_Face_Internal internal; /*@private end */ } FT_FaceRec ; FreeType root face class structure. A face object models a typeface in a font file. fields num_faces The number of faces in the font file. Some font formats can have multiple faces in a single font file. face_index This field holds two different values. Bits 0-15 are the index of the face in the font file (starting with value 0). They are set to 0 if there is only one face in the font file. [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation fonts only, holding the named instance index for the current face index (starting with value 1; value 0 indicates font access without a named instance). For non-variation fonts, bits 16-30 are ignored. If we have the third named instance of face 4, say, face_index is set to 0x00030004. Bit 31 is always zero (this is, face_index is always a positive value). [Since 2.9] Changing the design coordinates with FT_Set_Var_Design_Coordinates or FT_Set_Var_Blend_Coordinates does not influence the named instance index value (only FT_Set_Named_Instance does that). face_flags A set of bit flags that give important information about the face; see FT_FACE_FLAG_XXX for the details. style_flags The lower 16 bits contain a set of bit flags indicating the style of the face; see FT_STYLE_FLAG_XXX for the details. [Since 2.6.1] Bits 16-30 hold the number of named instances available for the current face if we have a GX or OpenType variation (sub)font. Bit 31 is always zero (this is, style_flags is always a positive value). Note that a variation font has always at least one named instance, namely the default instance. num_glyphs The number of glyphs in the face. If the face is scalable and has sbits (see num_fixed_sizes ), it is set to the number of outline glyphs. For CID-keyed fonts (not in an SFNT wrapper) this value gives the highest CID used in the font. family_name The face's family name. This is an ASCII string, usually in English, that describes the typeface's family (like \u2018Times New Roman\u2019, \u2018Bodoni\u2019, \u2018Garamond\u2019, etc). This is a least common denominator used to list fonts. Some formats (TrueType & OpenType) provide localized and Unicode versions of this string. Applications should use the format-specific interface to access them. Can be NULL (e.g., in fonts embedded in a PDF file). In case the font doesn't provide a specific family name entry, FreeType tries to synthesize one, deriving it from other name entries. style_name The face's style name. This is an ASCII string, usually in English, that describes the typeface's style (like \u2018Italic\u2019, \u2018Bold\u2019, \u2018Condensed\u2019, etc). Not all font formats provide a style name, so this field is optional, and can be set to NULL . As for family_name , some formats provide localized and Unicode versions of this string. Applications should use the format-specific interface to access them. num_fixed_sizes The number of bitmap strikes in the face. Even if the face is scalable, there might still be bitmap strikes, which are called \u2018sbits\u2019 in that case. available_sizes An array of FT_Bitmap_Size for all bitmap strikes in the face. It is set to NULL if there is no bitmap strike. Note that FreeType tries to sanitize the strike data since they are sometimes sloppy or incorrect, but this can easily fail. num_charmaps The number of charmaps in the face. charmaps An array of the charmaps of the face. generic A field reserved for client uses. See the FT_Generic type description. bbox The font bounding box. Coordinates are expressed in font units (see units_per_EM ). The box is large enough to contain any glyph from the font. Thus, bbox.yMax can be seen as the \u2018maximum ascender\u2019, and bbox.yMin as the \u2018minimum descender\u2019. Only relevant for scalable formats. Note that the bounding box might be off by (at least) one pixel for hinted fonts. See FT_Size_Metrics for further discussion. Note that the bounding box does not vary in OpenType variable fonts and should only be used in relation to the default instance. units_per_EM The number of font units per EM square for this face. This is typically 2048 for TrueType fonts, and 1000 for Type 1 fonts. Only relevant for scalable formats. ascender The typographic ascender of the face, expressed in font units. For font formats not having this information, it is set to bbox.yMax . Only relevant for scalable formats. descender The typographic descender of the face, expressed in font units. For font formats not having this information, it is set to bbox.yMin . Note that this field is negative for values below the baseline. Only relevant for scalable formats. height This value is the vertical distance between two consecutive baselines, expressed in font units. It is always positive. Only relevant for scalable formats. If you want the global glyph height, use ascender - descender . max_advance_width The maximum advance width, in font units, for all glyphs in this face. This can be used to make word wrapping computations faster. Only relevant for scalable formats. max_advance_height The maximum advance height, in font units, for all glyphs in this face. This is only relevant for vertical layouts, and is set to height for fonts that do not provide vertical metrics. Only relevant for scalable formats. underline_position The position, in font units, of the underline line for this face. It is the center of the underlining stem. Only relevant for scalable formats. underline_thickness The thickness, in font units, of the underline for this face. Only relevant for scalable formats. glyph The face's associated glyph slot(s). size The current active size for this face. charmap The current active charmap for this face. note Fields may be changed after a call to FT_Attach_File or FT_Attach_Stream . For an OpenType variation font, the values of the following fields can change after a call to FT_Set_Var_Design_Coordinates (and friends) if the font contains an \u2018MVAR\u2019 table: ascender , descender , height , underline_position , and underline_thickness . Especially for TrueType fonts see also the documentation for FT_Size_Metrics . FT_HAS_HORIZONTAL \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_HORIZONTAL ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_HORIZONTAL ) ) A macro that returns true whenever a face object contains horizontal metrics (this is true for all font formats though). also FT_HAS_VERTICAL can be used to check for vertical metrics. FT_HAS_VERTICAL \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_VERTICAL ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_VERTICAL ) ) A macro that returns true whenever a face object contains real vertical metrics (and not only synthesized ones).

See the available_sizes field of the FT_FaceRec structure. FT_HAS_GLYPH_NAMES \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_GLYPH_NAMES ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_GLYPH_NAMES ) ) A macro that returns true whenever a face object contains some glyph names that can be accessed through FT_Get_Glyph_Name . FT_HAS_COLOR \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_COLOR ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_COLOR ) ) A macro that returns true whenever a face object contains tables for color glyphs. since 2.5.1 FT_HAS_MULTIPLE_MASTERS \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_MULTIPLE_MASTERS ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_MULTIPLE_MASTERS ) ) A macro that returns true whenever a face object contains some multiple masters. The functions provided by FT_MULTIPLE_MASTERS_H are then available to choose the exact design you want. FT_HAS_SVG \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_SVG ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SVG ) ) A macro that returns true whenever a face object contains an \u2018SVG \u2019 OpenType table. since 2.12 FT_HAS_SBIX \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_SBIX ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SBIX ) ) A macro that returns true whenever a face object contains an \u2018sbix\u2019 OpenType table and outline glyphs. Currently, FreeType only supports bitmap glyphs in PNG format for this table (i.e., JPEG and TIFF formats are unsupported, as are Apple-specific formats not part of the OpenType specification). note For backward compatibility, a font with an \u2018sbix\u2019 table is treated as a bitmap-only face. Using FT_Open_Face with FT_PARAM_TAG_IGNORE_SBIX , an application can switch off \u2018sbix\u2019 handling so that the face is treated as an ordinary outline font with scalable outlines. Here is some pseudo code that roughly illustrates how to implement \u2018sbix\u2019 handling according to the OpenType specification. if ( FT_HAS_SBIX( face ) ) { // open font as a scalable one without sbix handling FT_Face face2; FT_Parameter param = { FT_PARAM_TAG_IGNORE_SBIX, NULL }; FT_Open_Args args = { FT_OPEN_PARAMS | ..., ..., 1, ¶m }; FT_Open_Face( library, &args, 0, &face2 ); <sort `face->available_size` as necessary into `preferred_sizes`[*]> for ( i = 0; i < face->num_fixed_sizes; i++ ) { size = preferred_sizes[i].size; error = FT_Set_Pixel_Sizes( face, size, size ); <error handling omitted> // check whether we have a glyph in a bitmap strike error = FT_Load_Glyph( face, glyph_index, FT_LOAD_SBITS_ONLY | FT_LOAD_BITMAP_METRICS_ONLY ); if ( error == FT_Err_Invalid_Argument ) continue; else if ( error ) <other error handling omitted> else break; } if ( i != face->num_fixed_sizes ) <load embedded bitmap with `FT_Load_Glyph`, scale it, display it, etc.> if ( i == face->num_fixed_sizes || FT_HAS_SBIX_OVERLAY( face ) ) <use `face2` to load outline glyph with `FT_Load_Glyph`, scale it, display it on top of the bitmap, etc.> } [*] Assuming a target value of 400dpi and available strike sizes 100, 200, 300, and 400dpi, a possible order might be [400, 200, 300, 100]: scaling 200dpi to 400dpi usually gives better results than scaling 300dpi to 400dpi; it is also much faster. However, scaling 100dpi to 400dpi can yield a too pixelated result, thus the preference might be 300dpi over 100dpi. since 2.12 FT_HAS_SBIX_OVERLAY \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_SBIX_OVERLAY ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SBIX_OVERLAY ) ) A macro that returns true whenever a face object contains an \u2018sbix\u2019 OpenType table with bit 1 in its flags field set, instructing the application to overlay the bitmap strike with the corresponding outline glyph. See FT_HAS_SBIX for pseudo code how to use it. since 2.12 FT_IS_SFNT \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_SFNT ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SFNT ) ) A macro that returns true whenever a face object contains a font whose format is based on the SFNT storage scheme. This usually means: TrueType fonts, OpenType fonts, as well as SFNT-based embedded bitmap fonts. If this macro is true, all functions defined in FT_SFNT_NAMES_H and FT_TRUETYPE_TABLES_H are available. FT_IS_SCALABLE \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_SCALABLE ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SCALABLE ) ) A macro that returns true whenever a face object contains a scalable font face (true for TrueType, Type 1, Type 42, CID, OpenType/CFF, and PFR font formats). FT_IS_FIXED_WIDTH \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_FIXED_WIDTH ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_FIXED_WIDTH ) ) A macro that returns true whenever a face object contains a font face that contains fixed-width (or \u2018monospace\u2019, \u2018fixed-pitch\u2019, etc.) glyphs. FT_IS_CID_KEYED \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_CID_KEYED ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_CID_KEYED ) ) A macro that returns true whenever a face object contains a CID-keyed font. See the discussion of FT_FACE_FLAG_CID_KEYED for more details. If this macro is true, all functions defined in FT_CID_H are available. FT_IS_TRICKY \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_TRICKY ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_TRICKY ) ) A macro that returns true whenever a face represents a \u2018tricky\u2019 font. See the discussion of FT_FACE_FLAG_TRICKY for more details. FT_IS_NAMED_INSTANCE \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_NAMED_INSTANCE ( face ) \\ ( !!( (face)->face_index & 0x7FFF0000L ) ) A macro that returns true whenever a face object is a named instance of a GX or OpenType variation font. [Since 2.9] Changing the design coordinates with FT_Set_Var_Design_Coordinates or FT_Set_Var_Blend_Coordinates does not influence the return value of this macro (only FT_Set_Named_Instance does that). since 2.7 FT_IS_VARIATION \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_IS_VARIATION ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_VARIATION ) ) A macro that returns true whenever a face object has been altered by FT_Set_MM_Design_Coordinates , FT_Set_Var_Design_Coordinates , or FT_Set_Var_Blend_Coordinates . since 2.9 FT_SizeRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_SizeRec_ { FT_Face face; /* parent face object */ FT_Generic generic; /* generic pointer for client uses */ FT_Size_Metrics metrics; /* size metrics */ FT_Size_Internal internal; } FT_SizeRec ; FreeType root size class structure. A size object models a face object at a given size. fields face Handle to the parent face object. generic A typeless pointer, unused by the FreeType library or any of its drivers. It can be used by client applications to link their own data to each size object. metrics Metrics for this size object. This field is read-only. FT_Size_Metrics \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_Metrics_ { FT_UShort x_ppem; /* horizontal pixels per EM */ FT_UShort y_ppem; /* vertical pixels per EM */ FT_Fixed x_scale; /* scaling values used to convert font */ FT_Fixed y_scale; /* units to 26.6 fractional pixels */ FT_Pos ascender; /* ascender in 26.6 frac. pixels */ FT_Pos descender; /* descender in 26.6 frac. pixels */ FT_Pos height; /* text height in 26.6 frac. pixels */ FT_Pos max_advance; /* max horizontal advance, in 26.6 pixels */ } FT_Size_Metrics ; The size metrics structure gives the metrics of a size object. fields x_ppem The width of the scaled EM square in pixels, hence the term \u2018ppem\u2019 (pixels per EM). It is also referred to as \u2018nominal width\u2019. y_ppem The height of the scaled EM square in pixels, hence the term \u2018ppem\u2019 (pixels per EM). It is also referred to as \u2018nominal height\u2019. x_scale A 16.16 fractional scaling value to convert horizontal metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats. y_scale A 16.16 fractional scaling value to convert vertical metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats. ascender The ascender in 26.6 fractional pixels, rounded up to an integer value. See FT_FaceRec for the details. descender The descender in 26.6 fractional pixels, rounded down to an integer value. See FT_FaceRec for the details. height The height in 26.6 fractional pixels, rounded to an integer value. See FT_FaceRec for the details. max_advance The maximum advance width in 26.6 fractional pixels, rounded to an integer value. See FT_FaceRec for the details. note The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in FT_FaceRec . Some values like ascender or descender are rounded for historical reasons; more precise values (for outline fonts) can be derived by scaling the corresponding FT_FaceRec values manually, with code similar to the following. scaled_ascender = FT_MulFix( face->ascender, size_metrics->y_scale ); Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel! Indeed, the only way to get the exact metrics is to render all glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations. The FT_Size_Metrics structure is valid for bitmap fonts also. TrueType fonts with native bytecode hinting All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions. The application has to cater for this, especially if it wants to rely on a TTF's vertical data (for example, to properly align box characters vertically). Only the application knows in advance that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an FT_Size object but much later, namely while calling FT_Load_Glyph . Here is some pseudo code that illustrates a possible solution. font_format = FT_Get_Font_Format( face ); if ( !strcmp( font_format, \"TrueType\" ) && do_native_bytecode_hinting ) { ascender = ROUND( FT_MulFix( face->ascender, size_metrics->y_scale ) ); descender = ROUND( FT_MulFix( face->descender, size_metrics->y_scale ) ); } else { ascender = size_metrics->ascender; descender = size_metrics->descender; } height = size_metrics->height; max_advance = size_metrics->max_advance; FT_GlyphSlotRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_GlyphSlotRec_ { FT_Library library; FT_Face face; FT_GlyphSlot next; FT_UInt glyph_index; /* new in 2.10; was reserved previously */ FT_Generic generic; FT_Glyph_Metrics metrics; FT_Fixed linearHoriAdvance; FT_Fixed linearVertAdvance; FT_Vector advance; FT_Glyph_Format format; FT_Bitmap bitmap; FT_Int bitmap_left; FT_Int bitmap_top; FT_Outline outline; FT_UInt num_subglyphs; FT_SubGlyph subglyphs; void * control_data; long control_len; FT_Pos lsb_delta; FT_Pos rsb_delta; void * other; FT_Slot_Internal internal; } FT_GlyphSlotRec ; FreeType root glyph slot class structure. A glyph slot is a container where individual glyphs can be loaded, be they in outline or bitmap format. fields library A handle to the FreeType library instance this slot belongs to. face A handle to the parent face object. next In some cases (like some font tools), several glyph slots per face object can be a good thing. As this is rare, the glyph slots are listed through a direct, single-linked list using its next field. glyph_index [Since 2.10] The glyph index passed as an argument to FT_Load_Glyph while initializing the glyph slot. generic A typeless pointer unused by the FreeType library or any of its drivers. It can be used by client applications to link their own data to each glyph slot object. metrics The metrics of the last loaded glyph in the slot. The returned values depend on the last load flags (see the FT_Load_Glyph API function) and can be expressed either in 26.6 fractional pixels or font units. Note that even when the glyph image is transformed, the metrics are not. linearHoriAdvance The advance width of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for scalable glyphs. linearVertAdvance The advance height of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for scalable glyphs. advance This shorthand is, depending on FT_LOAD_IGNORE_TRANSFORM , the transformed (hinted) advance width for the glyph, in 26.6 fractional pixel format. As specified with FT_LOAD_VERTICAL_LAYOUT , it uses either the horiAdvance or the vertAdvance value of metrics field. format This field indicates the format of the image contained in the glyph slot. Typically FT_GLYPH_FORMAT_BITMAP , FT_GLYPH_FORMAT_OUTLINE , or FT_GLYPH_FORMAT_COMPOSITE , but other values are possible. bitmap This field is used as a bitmap descriptor. Note that the address and content of the bitmap buffer can change between calls of FT_Load_Glyph and a few other functions. bitmap_left The bitmap's left bearing expressed in integer pixels. bitmap_top The bitmap's top bearing expressed in integer pixels. This is the distance from the baseline to the top-most glyph scanline, upwards y coordinates being positive . outline The outline descriptor for the current glyph image if its format is FT_GLYPH_FORMAT_OUTLINE . Once a glyph is loaded, outline can be transformed, distorted, emboldened, etc. However, it must not be freed. [Since 2.10.1] If FT_LOAD_NO_SCALE is set, outline coordinates of OpenType variation fonts for a selected instance are internally handled as 26.6 fractional font units but returned as (rounded) integers, as expected. To get unrounded font units, don't use FT_LOAD_NO_SCALE but load the glyph with FT_LOAD_NO_HINTING and scale it, using the font's units_per_EM value as the ppem. num_subglyphs The number of subglyphs in a composite glyph. This field is only valid for the composite glyph format that should normally only be loaded with the FT_LOAD_NO_RECURSE flag. subglyphs An array of subglyph descriptors for composite glyphs. There are num_subglyphs elements in there. Currently internal to FreeType. control_data Certain font drivers can also return the control data for a given glyph image (e.g. TrueType bytecode, Type 1 charstrings, etc.). This field is a pointer to such data; it is currently internal to FreeType. control_len This is the length in bytes of the control data. Currently internal to FreeType. other Reserved. lsb_delta The difference between hinted and unhinted left side bearing while auto-hinting is active. Zero otherwise. rsb_delta The difference between hinted and unhinted right side bearing while auto-hinting is active. Zero otherwise. note If FT_Load_Glyph is called with default flags (see FT_LOAD_DEFAULT ) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type 1 formats). [Since 2.9] The prospective bitmap metrics are calculated according to FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even if FT_LOAD_RENDER is not set. This image can later be converted into a bitmap by calling FT_Render_Glyph . This function searches the current renderer for the native image's format, then invokes it. The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in slot->bitmap . Note that slot->bitmap_left and slot->bitmap_top are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, slot->format is also changed to FT_GLYPH_FORMAT_BITMAP . Here is a small pseudo code fragment that shows how to use lsb_delta and rsb_delta to do fractional positioning of glyphs: FT_GlyphSlot slot = face->glyph; FT_Pos origin_x = 0; for all glyphs do <load glyph with `FT_Load_Glyph'> FT_Outline_Translate( slot->outline, origin_x & 63, 0 ); <save glyph image, or render glyph, or ...> <compute kern between current and next glyph and add it to `origin_x'> origin_x += slot->advance.x; origin_x += slot->lsb_delta - slot->rsb_delta; endfor Here is another small pseudo code fragment that shows how to use lsb_delta and rsb_delta to improve integer positioning of glyphs: FT_GlyphSlot slot = face->glyph; FT_Pos origin_x = 0; FT_Pos prev_rsb_delta = 0; for all glyphs do <compute kern between current and previous glyph and add it to `origin_x'> <load glyph with `FT_Load_Glyph'> if ( prev_rsb_delta - slot->lsb_delta > 32 ) origin_x -= 64; else if ( prev_rsb_delta - slot->lsb_delta < -31 ) origin_x += 64; prev_rsb_delta = slot->rsb_delta; <save glyph image, or render glyph, or ...> origin_x += slot->advance.x; endfor If you use strong auto-hinting, you must apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then. FT_Glyph_Metrics \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Glyph_Metrics_ { FT_Pos width; FT_Pos height; FT_Pos horiBearingX; FT_Pos horiBearingY; FT_Pos horiAdvance; FT_Pos vertBearingX; FT_Pos vertBearingY; FT_Pos vertAdvance; } FT_Glyph_Metrics ; A structure to model the metrics of a single glyph. The values are expressed in 26.6 fractional pixel format; if the flag FT_LOAD_NO_SCALE has been used while loading the glyph, values are expressed in font units instead. fields width The glyph's width. height The glyph's height. horiBearingX Left side bearing for horizontal layout. horiBearingY Top side bearing for horizontal layout. horiAdvance Advance width for horizontal layout. vertBearingX Left side bearing for vertical layout. vertBearingY Top side bearing for vertical layout. Larger positive values mean further below the vertical glyph origin. vertAdvance Advance height for vertical layout. Positive values mean the glyph has a positive advance downward. note If not disabled with FT_LOAD_NO_HINTING , the values represent dimensions of the hinted glyph (in case hinting is applicable). Stroking a glyph with an outside border does not increase horiAdvance or vertAdvance ; you have to manually adjust these values to account for the added width and height. FreeType doesn't use the \u2018VORG\u2019 table data for CFF fonts because it doesn't have an interface to quickly retrieve the glyph height. The y coordinate of the vertical origin can be simply computed as vertBearingY + height after loading a glyph. FT_SubGlyph \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_SubGlyphRec_* FT_SubGlyph ; The subglyph structure is an internal object used to describe subglyphs (for example, in the case of composites). note The subglyph implementation is not part of the high-level API, hence the forward structure declaration. You can however retrieve subglyph information with FT_Get_SubGlyph_Info . FT_Bitmap_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Bitmap_Size_ { FT_Short height; FT_Short width; FT_Pos size; FT_Pos x_ppem; FT_Pos y_ppem; } FT_Bitmap_Size ; This structure models the metrics of a bitmap strike (i.e., a set of glyphs for a given point size and resolution) in a bitmap font. It is used for the available_sizes field of FT_Face . fields height The vertical distance, in pixels, between two consecutive baselines. It is always positive. width The average width, in pixels, of all glyphs in the strike. size The nominal size of the strike in 26.6 fractional points. This field is not very useful. x_ppem The horizontal ppem (nominal width) in 26.6 fractional pixels. y_ppem The vertical ppem (nominal height) in 26.6 fractional pixels. note Windows FNT: The nominal size given in a FNT font is not reliable. If the driver finds it incorrect, it sets size to some calculated values, and x_ppem and y_ppem to the pixel width and height given in the font, respectively. TrueType embedded bitmaps: size , width , and height values are not contained in the bitmap strike itself. They are computed from the global font parameters. FT_Init_FreeType \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Init_FreeType ( FT_Library *alibrary ); Initialize a new FreeType library object. The set of modules that are registered by this function is determined at build time. output alibrary A handle to a new library object. return FreeType error code. 0 means success. note In case you want to provide your own memory allocating routines, use FT_New_Library instead, followed by a call to FT_Add_Default_Modules (or a series of calls to FT_Add_Module ) and FT_Set_Default_Properties . See the documentation of FT_Library and FT_Face for multi-threading issues. If you need reference-counting (cf. FT_Reference_Library ), use FT_New_Library and FT_Done_Library . If compilation option FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES is set, this function reads the FREETYPE_PROPERTIES environment variable to control driver properties. See section \u2018 Driver properties \u2019 for more. FT_Done_FreeType \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Done_FreeType ( FT_Library library ); Destroy a given FreeType library object and all of its children, including resources, drivers, faces, sizes, etc. input library A handle to the target library object. return FreeType error code. 0 means success. FT_New_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_New_Face ( FT_Library library, const char * filepathname, FT_Long face_index, FT_Face *aface ); Call FT_Open_Face to open a font by its pathname. inout library A handle to the library resource. input pathname A path to the font file. face_index See FT_Open_Face for a detailed description of this parameter. output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note The pathname string should be recognizable as such by a standard fopen call on your system; in particular, this means that pathname must not contain null bytes. If that is not sufficient to address all file name possibilities (for example, to handle wide character file names on Windows in UTF-16 encoding) you might use FT_Open_Face to pass a memory array or a stream object instead. Use FT_Done_Face to destroy the created FT_Face object (along with its slot and sizes). FT_Done_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Done_Face ( FT_Face face ); Discard a given face object, as well as all of its child slots and sizes. input face A handle to a target face object. return FreeType error code. 0 means success. note See the discussion of reference counters in the description of FT_Reference_Face . FT_Reference_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Reference_Face ( FT_Face face ); A counter gets initialized to 1 at the time an FT_Face structure is created. This function increments the counter. FT_Done_Face then only destroys a face if the counter is 1, otherwise it simply decrements the counter. This function helps in managing life-cycles of structures that reference FT_Face objects. input face A handle to a target face object. return FreeType error code. 0 means success. since 2.4.2 FT_New_Memory_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_New_Memory_Face ( FT_Library library, const FT_Byte * file_base, FT_Long file_size, FT_Long face_index, FT_Face *aface ); Call FT_Open_Face to open a font that has been loaded into memory. inout library A handle to the library resource. input file_base A pointer to the beginning of the font data. file_size The size of the memory chunk used by the font data. face_index See FT_Open_Face for a detailed description of this parameter. output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note You must not deallocate the memory before calling FT_Done_Face . FT_Face_Properties \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Face_Properties ( FT_Face face, FT_UInt num_properties, FT_Parameter * properties ); Set or override certain (library or module-wide) properties on a face-by-face basis. Useful for finer-grained control and avoiding locks on shared structures (threads can modify their own faces as they see fit). Contrary to FT_Property_Set , this function uses FT_Parameter so that you can pass multiple properties to the target face in one call. Note that only a subset of the available properties can be controlled. FT_PARAM_TAG_STEM_DARKENING (stem darkening, corresponding to the property no-stem-darkening provided by the \u2018autofit\u2019, \u2018cff\u2019, \u2018type1\u2019, and \u2018t1cid\u2019 modules; see no-stem-darkening ). FT_PARAM_TAG_LCD_FILTER_WEIGHTS (LCD filter weights, corresponding to function FT_Library_SetLcdFilterWeights ). FT_PARAM_TAG_RANDOM_SEED (seed value for the CFF, Type 1, and CID \u2018random\u2019 operator, corresponding to the random-seed property provided by the \u2018cff\u2019, \u2018type1\u2019, and \u2018t1cid\u2019 modules; see random-seed ). Pass NULL as data in FT_Parameter for a given tag to reset the option and use the library or module default again. input face A handle to the source face object. num_properties The number of properties that follow. properties A handle to an FT_Parameter array with num_properties elements. return FreeType error code. 0 means success. example Here is an example that sets three properties. You must define FT_CONFIG_OPTION_SUBPIXEL_RENDERING to make the LCD filter examples work. FT_Parameter property1; FT_Bool darken_stems = 1; FT_Parameter property2; FT_LcdFiveTapFilter custom_weight = { 0x11, 0x44, 0x56, 0x44, 0x11 }; FT_Parameter property3; FT_Int32 random_seed = 314159265; FT_Parameter properties[3] = { property1, property2, property3 }; property1.tag = FT_PARAM_TAG_STEM_DARKENING; property1.data = &darken_stems; property2.tag = FT_PARAM_TAG_LCD_FILTER_WEIGHTS; property2.data = custom_weight; property3.tag = FT_PARAM_TAG_RANDOM_SEED; property3.data = &random_seed; FT_Face_Properties( face, 3, properties ); The next example resets a single property to its default value. FT_Parameter property; property.tag = FT_PARAM_TAG_LCD_FILTER_WEIGHTS; property.data = NULL; FT_Face_Properties( face, 1, &property ); since 2.8 FT_Open_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Open_Face ( FT_Library library, const FT_Open_Args * args, FT_Long face_index, FT_Face *aface ); Create a face object from a given resource described by FT_Open_Args . inout library A handle to the library resource. input args A pointer to an FT_Open_Args structure that must be filled by the caller. face_index This field holds two different values. Bits 0-15 are the index of the face in the font file (starting with value 0). Set it to 0 if there is only one face in the font file. [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation fonts only, specifying the named instance index for the current face index (starting with value 1; value 0 makes FreeType ignore named instances). For non-variation fonts, bits 16-30 are ignored. Assuming that you want to access the third named instance in face 4, face_index should be set to 0x00030004. If you want to access face 4 without variation handling, simply set face_index to value 4. FT_Open_Face and its siblings can be used to quickly check whether the font format of a given font resource is supported by FreeType. In general, if the face_index argument is negative, the function's return value is 0 if the font format is recognized, or non-zero otherwise. The function allocates a more or less empty face handle in *aface (if aface isn't NULL ); the only two useful fields in this special case are face->num_faces and face->style_flags . For any negative value of face_index , face->num_faces gives the number of faces within the font file. For the negative value \u2018-(N+1)\u2019 (with \u2018N\u2019 a non-negative 16-bit value), bits 16-30 in face->style_flags give the number of named instances in face \u2018N\u2019 if we have a variation font (or zero otherwise). After examination, the returned FT_Face structure should be deallocated with a call to FT_Done_Face . output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note Unlike FreeType 1.x, this function automatically creates a glyph slot for the face object that can be accessed directly through face->glyph . Each new face object created with this function also owns a default FT_Size object, accessible as face->size . One FT_Library instance can have multiple face objects, this is, FT_Open_Face and its siblings can be called multiple times using the same library argument. See the discussion of reference counters in the description of FT_Reference_Face . If FT_OPEN_STREAM is set in args->flags , the stream in args->stream is automatically closed before this function returns any error (including FT_Err_Invalid_Argument ). example To loop over all faces, use code similar to the following snippet (omitting the error handling). ... FT_Face face; FT_Long i, num_faces; error = FT_Open_Face( library, args, -1, &face ); if ( error ) { ... } num_faces = face->num_faces; FT_Done_Face( face ); for ( i = 0; i < num_faces; i++ ) { ... error = FT_Open_Face( library, args, i, &face ); ... FT_Done_Face( face ); ... } To loop over all valid values for face_index , use something similar to the following snippet, again without error handling. The code accesses all faces immediately (thus only a single call of FT_Open_Face within the do-loop), with and without named instances. ... FT_Face face; FT_Long num_faces = 0; FT_Long num_instances = 0; FT_Long face_idx = 0; FT_Long instance_idx = 0; do { FT_Long id = ( instance_idx << 16 ) + face_idx; error = FT_Open_Face( library, args, id, &face ); if ( error ) { ... } num_faces = face->num_faces; num_instances = face->style_flags >> 16; ... FT_Done_Face( face ); if ( instance_idx < num_instances ) instance_idx++; else { face_idx++; instance_idx = 0; } } while ( face_idx < num_faces ) FT_Open_Args \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Open_Args_ { FT_UInt flags; const FT_Byte * memory_base; FT_Long memory_size; FT_String * pathname; FT_Stream stream; FT_Module driver; FT_Int num_params; FT_Parameter * params; } FT_Open_Args ; A structure to indicate how to open a new font file or stream. A pointer to such a structure can be used as a parameter for the functions FT_Open_Face and FT_Attach_Stream . fields flags A set of bit flags indicating how to use the structure. memory_base The first byte of the file in memory. memory_size The size in bytes of the file in memory. pathname A pointer to an 8-bit file pathname, which must be a C string (i.e., no null bytes except at the very end). The pointer is not owned by FreeType. stream A handle to a source stream object. driver This field is exclusively used by FT_Open_Face ; it simply specifies the font driver to use for opening the face. If set to NULL , FreeType tries to load the face with each one of the drivers in its list. num_params The number of extra parameters. params Extra parameters passed to the font driver when opening a new face. note The stream type is determined by the contents of flags : If the FT_OPEN_MEMORY bit is set, assume that this is a memory file of memory_size bytes, located at memory_address . The data are not copied, and the client is responsible for releasing and destroying them after the corresponding call to FT_Done_Face . Otherwise, if the FT_OPEN_STREAM bit is set, assume that a custom input stream stream is used. Otherwise, if the FT_OPEN_PATHNAME bit is set, assume that this is a normal file and use pathname to open it. If none of the above bits are set or if multiple are set at the same time, the flags are invalid and FT_Open_Face fails. If the FT_OPEN_DRIVER bit is set, FT_Open_Face only tries to open the file with the driver whose handler is in driver . If the FT_OPEN_PARAMS bit is set, the parameters given by num_params and params is used. They are ignored otherwise. Ideally, both the pathname and params fields should be tagged as \u2018const\u2019; this is missing for API backward compatibility. In other words, applications should treat them as read-only. FT_Parameter \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Parameter_ { FT_ULong tag; FT_Pointer data; } FT_Parameter ; A simple structure to pass more or less generic parameters to FT_Open_Face and FT_Face_Properties . fields tag A four-byte identification tag. data A pointer to the parameter data. note The ID and function of parameters are driver-specific. See section \u2018 Parameter Tags \u2019 for more information. FT_Attach_File \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Attach_File ( FT_Face face, const char * filepathname ); Call FT_Attach_Stream to attach a file. inout face The target face object. input filepathname The pathname. return FreeType error code. 0 means success. FT_Attach_Stream \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Attach_Stream ( FT_Face face, const FT_Open_Args * parameters ); \u2018Attach\u2019 data to a face object. Normally, this is used to read additional information for the face object. For example, you can attach an AFM file that comes with a Type 1 font to get the kerning values and other metrics. inout face The target face object. input parameters A pointer to FT_Open_Args that must be filled by the caller. return FreeType error code. 0 means success. note The meaning of the \u2018attach\u2019 (i.e., what really happens when the new file is read) is not fixed by FreeType itself. It really depends on the font format (and thus the font driver). Client applications are expected to know what they are doing when invoking this function. Most drivers simply do not implement file or stream attachments. FT_Set_Char_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Char_Size ( FT_Face face, FT_F26Dot6 char_width, FT_F26Dot6 char_height, FT_UInt horz_resolution, FT_UInt vert_resolution ); Call FT_Request_Size to request the nominal size (in points). inout face A handle to a target face object. input char_width The nominal width, in 26.6 fractional points. char_height The nominal height, in 26.6 fractional points. horz_resolution The horizontal resolution in dpi. vert_resolution The vertical resolution in dpi. return FreeType error code. 0 means success. note While this function allows fractional points as input values, the resulting ppem value for the given resolution is always rounded to the nearest integer. If either the character width or height is zero, it is set equal to the other value. If either the horizontal or vertical resolution is zero, it is set equal to the other value. A character width or height smaller than 1pt is set to 1pt; if both resolution values are zero, they are set to 72dpi. Don't use this function if you are using the FreeType cache API. FT_Set_Pixel_Sizes \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Pixel_Sizes ( FT_Face face, FT_UInt pixel_width, FT_UInt pixel_height ); Call FT_Request_Size to request the nominal size (in pixels). inout face A handle to the target face object. input pixel_width The nominal width, in pixels. pixel_height The nominal height, in pixels. return FreeType error code. 0 means success. note You should not rely on the resulting glyphs matching or being constrained to this pixel size. Refer to FT_Request_Size to understand how requested sizes relate to actual sizes. Don't use this function if you are using the FreeType cache API. FT_Request_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Request_Size ( FT_Face face, FT_Size_Request req ); Resize the scale of the active FT_Size object in a face. inout face A handle to a target face object. input req A pointer to a FT_Size_RequestRec . return FreeType error code. 0 means success. note Although drivers may select the bitmap strike matching the request, you should not rely on this if you intend to select a particular bitmap strike. Use FT_Select_Size instead in that case. The relation between the requested size and the resulting glyph size is dependent entirely on how the size is defined in the source face. The font designer chooses the final size of each glyph relative to this size. For more information refer to \u2018 https://www.freetype.org/freetype2/docs/glyphs/glyphs-2.html \u2019. Contrary to FT_Set_Char_Size , this function doesn't have special code to normalize zero-valued widths, heights, or resolutions, which are treated as FT_LOAD_NO_SCALE . Don't use this function if you are using the FreeType cache API. FT_Select_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Select_Size ( FT_Face face, FT_Int strike_index ); Select a bitmap strike. To be more precise, this function sets the scaling factors of the active FT_Size object in a face so that bitmaps from this particular strike are taken by FT_Load_Glyph and friends. inout face A handle to a target face object. input strike_index The index of the bitmap strike in the available_sizes field of FT_FaceRec structure. return FreeType error code. 0 means success. note For bitmaps embedded in outline fonts it is common that only a subset of the available glyphs at a given ppem value is available. FreeType silently uses outlines if there is no bitmap for a given glyph index. For GX and OpenType variation fonts, a bitmap strike makes sense only if the default instance is active (this is, no glyph variation takes place); otherwise, FreeType simply ignores bitmap strikes. The same is true for all named instances that are different from the default instance. Don't use this function if you are using the FreeType cache API. FT_Size_Request_Type \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Size_Request_Type_ { FT_SIZE_REQUEST_TYPE_NOMINAL , FT_SIZE_REQUEST_TYPE_REAL_DIM , FT_SIZE_REQUEST_TYPE_BBOX , FT_SIZE_REQUEST_TYPE_CELL , FT_SIZE_REQUEST_TYPE_SCALES , FT_SIZE_REQUEST_TYPE_MAX } FT_Size_Request_Type ; An enumeration type that lists the supported size request types, i.e., what input size (in font units) maps to the requested output size (in pixels, as computed from the arguments of FT_Size_Request ). values FT_SIZE_REQUEST_TYPE_NOMINAL The nominal size. The units_per_EM field of FT_FaceRec is used to determine both scaling values. This is the standard scaling found in most applications. In particular, use this size request type for TrueType fonts if they provide optical scaling or something similar. Note, however, that units_per_EM is a rather abstract value which bears no relation to the actual size of the glyphs in a font. FT_SIZE_REQUEST_TYPE_REAL_DIM The real dimension. The sum of the ascender and (minus of) the descender fields of FT_FaceRec is used to determine both scaling values. FT_SIZE_REQUEST_TYPE_BBOX The font bounding box. The width and height of the bbox field of FT_FaceRec are used to determine the horizontal and vertical scaling value, respectively. FT_SIZE_REQUEST_TYPE_CELL The max_advance_width field of FT_FaceRec is used to determine the horizontal scaling value; the vertical scaling value is determined the same way as FT_SIZE_REQUEST_TYPE_REAL_DIM does. Finally, both scaling values are set to the smaller one. This type is useful if you want to specify the font size for, say, a window of a given dimension and 80x24 cells. FT_SIZE_REQUEST_TYPE_SCALES Specify the scaling values directly. note The above descriptions only apply to scalable formats. For bitmap formats, the behaviour is up to the driver. See the note section of FT_Size_Metrics if you wonder how size requesting relates to scaling values. FT_Size_RequestRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_RequestRec_ { FT_Size_Request_Type type; FT_Long width; FT_Long height; FT_UInt horiResolution; FT_UInt vertResolution; } FT_Size_RequestRec ; A structure to model a size request. fields type See FT_Size_Request_Type . width The desired width, given as a 26.6 fractional point value (with 72pt = 1in). height The desired height, given as a 26.6 fractional point value (with 72pt = 1in). horiResolution The horizontal resolution (dpi, i.e., pixels per inch). If set to zero, width is treated as a 26.6 fractional pixel value, which gets internally rounded to an integer. vertResolution The vertical resolution (dpi, i.e., pixels per inch). If set to zero, height is treated as a 26.6 fractional pixel value, which gets internally rounded to an integer. note If width is zero, the horizontal scaling value is set equal to the vertical scaling value, and vice versa. If type is FT_SIZE_REQUEST_TYPE_SCALES , width and height are interpreted directly as 16.16 fractional scaling values, without any further modification, and both horiResolution and vertResolution are ignored. FT_Size_Request \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_RequestRec_ * FT_Size_Request ; A handle to a size request structure. FT_Set_Transform \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( void ) FT_Set_Transform ( FT_Face face, FT_Matrix * matrix, FT_Vector * delta ); Set the transformation that is applied to glyph images when they are loaded into a glyph slot through FT_Load_Glyph . inout face A handle to the source face object. input matrix A pointer to the transformation's 2x2 matrix. Use NULL for the identity matrix. delta A pointer to the translation vector. Use NULL for the null vector. note This function is provided as a convenience, but keep in mind that FT_Matrix coefficients are only 16.16 fixed-point values, which can limit the accuracy of the results. Using floating-point computations to perform the transform directly in client code instead will always yield better numbers. The transformation is only applied to scalable image formats after the glyph has been loaded. It means that hinting is unaltered by the transformation and is performed on the character size given in the last call to FT_Set_Char_Size or FT_Set_Pixel_Sizes . Note that this also transforms the face.glyph.advance field, but not the values in face.glyph.metrics . FT_Get_Transform \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( void ) FT_Get_Transform ( FT_Face face, FT_Matrix * matrix, FT_Vector * delta ); Return the transformation that is applied to glyph images when they are loaded into a glyph slot through FT_Load_Glyph . See FT_Set_Transform for more details. input face A handle to the source face object. output matrix A pointer to a transformation's 2x2 matrix. Set this to NULL if you are not interested in the value. delta A pointer to a translation vector. Set this to NULL if you are not interested in the value. since 2.11 FT_Load_Glyph \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Load_Glyph ( FT_Face face, FT_UInt glyph_index, FT_Int32 load_flags ); Load a glyph into the glyph slot of a face object. inout face A handle to the target face object where the glyph is loaded. input glyph_index The index of the glyph in the font file. For CID-keyed fonts (either in PS or in CFF format) this argument specifies the CID value. load_flags A flag indicating what to load for this glyph. The FT_LOAD_XXX flags can be used to control the glyph loading process (e.g., whether the outline should be scaled, whether to load bitmaps or not, whether to hint the outline, etc). return FreeType error code. 0 means success. note For proper scaling and hinting, the active FT_Size object owned by the face has to be meaningfully initialized by calling FT_Set_Char_Size before this function, for example. The loaded glyph may be transformed. See FT_Set_Transform for the details. For subsetted CID-keyed fonts, FT_Err_Invalid_Argument is returned for invalid CID values (this is, for CID values that don't have a corresponding glyph in the font). See the discussion of the FT_FACE_FLAG_CID_KEYED flag for more details. If you receive FT_Err_Glyph_Too_Big , try getting the glyph outline at EM size, then scale it manually and fill it as a graphics operation. FT_Get_Char_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_UInt ) FT_Get_Char_Index ( FT_Face face, FT_ULong charcode ); Return the glyph index of a given character code. This function uses the currently selected charmap to do the mapping. input face A handle to the source face object. charcode The character code. return The glyph index. 0 means \u2018undefined character code\u2019. note If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the \u2018missing glyph\u2019. If the first glyph is not named \u2018.notdef\u2019, then for Type 1 and Type 42 fonts, \u2018.notdef\u2019 will be moved into the glyph ID 0 position, and whatever was there will be moved to the position \u2018.notdef\u2019 had. For Type 1 fonts, if there is no \u2018.notdef\u2019 glyph at all, then one will be created at index 0 and whatever was there will be moved to the last index \u2013 Type 42 fonts are considered invalid under this condition. FT_Get_First_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_ULong ) FT_Get_First_Char ( FT_Face face, FT_UInt *agindex ); Return the first character code in the current charmap of a given face, together with its corresponding glyph index. input face A handle to the source face object. output agindex Glyph index of first character code. 0 if charmap is empty. return The charmap's first character code. note You should use this function together with FT_Get_Next_Char to parse all character codes available in a given charmap. The code should look like this: FT_ULong charcode; FT_UInt gindex; charcode = FT_Get_First_Char( face, &gindex ); while ( gindex != 0 ) { ... do something with (charcode,gindex) pair ... charcode = FT_Get_Next_Char( face, charcode, &gindex ); } Be aware that character codes can have values up to 0xFFFFFFFF; this might happen for non-Unicode or malformed cmaps. However, even with regular Unicode encoding, so-called \u2018last resort fonts\u2019 (using SFNT cmap format 13, see function FT_Get_CMap_Format ) normally have entries for all Unicode characters up to 0x1FFFFF, which can cause a lot of iterations. Note that *agindex is set to 0 if the charmap is empty. The result itself can be 0 in two cases: if the charmap is empty or if the value 0 is the first valid character code. FT_Get_Next_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_ULong ) FT_Get_Next_Char ( FT_Face face, FT_ULong char_code, FT_UInt *agindex ); Return the next character code in the current charmap of a given face following the value char_code , as well as the corresponding glyph index. input face A handle to the source face object. char_code The starting character code. output agindex Glyph index of next character code. 0 if charmap is empty. return The charmap's next character code. note You should use this function with FT_Get_First_Char to walk over all character codes available in a given charmap. See the note for that function for a simple code example. Note that *agindex is set to 0 when there are no more codes in the charmap. FT_Load_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Load_Char ( FT_Face face, FT_ULong char_code, FT_Int32 load_flags ); Load a glyph into the glyph slot of a face object, accessed by its character code. inout face A handle to a target face object where the glyph is loaded. input char_code The glyph's character code, according to the current charmap used in the face. load_flags A flag indicating what to load for this glyph. The FT_LOAD_XXX constants can be used to control the glyph loading process (e.g., whether the outline should be scaled, whether to load bitmaps or not, whether to hint the outline, etc). return FreeType error code. 0 means success. note This function simply calls FT_Get_Char_Index and FT_Load_Glyph . Many fonts contain glyphs that can't be loaded by this function since its glyph indices are not listed in any of the font's charmaps. If no active cmap is set up (i.e., face->charmap is zero), the call to FT_Get_Char_Index is omitted, and the function behaves identically to FT_Load_Glyph . FT_LOAD_TARGET_MODE \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_LOAD_TARGET_MODE ( x ) \\ FT_STATIC_CAST( FT_Render_Mode , ( (x) >> 16 ) & 15 ) Return the FT_Render_Mode corresponding to a given FT_LOAD_TARGET_XXX value. FT_Render_Glyph \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Render_Glyph ( FT_GlyphSlot slot, FT_Render_Mode render_mode ); Convert a given glyph image to a bitmap. It does so by inspecting the glyph image format, finding the relevant renderer, and invoking it. inout slot A handle to the glyph slot containing the image to convert. input render_mode The render mode used to render the glyph image into a bitmap. See FT_Render_Mode for a list of possible values. If FT_RENDER_MODE_NORMAL is used, a previous call of FT_Load_Glyph with flag FT_LOAD_COLOR makes FT_Render_Glyph provide a default blending of colored glyph layers associated with the current glyph slot (provided the font contains such layers) instead of rendering the glyph slot's outline. This is an experimental feature; see FT_LOAD_COLOR for more information. return FreeType error code. 0 means success. note When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white). On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception. This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness \u2013 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or \u2018dirt\u2019 around it. The situation is especially ugly for diagonal stems like in \u2018w\u2019 glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't. The blending function for placing text over a background is dst = alpha * src + (1 - alpha) * dst , which is known as the OVER operator. To correctly composite an anti-aliased pixel of a glyph onto a surface, take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space, use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and apply inverse gamma to the blended pixel and write it back to the image. Internal testing at Adobe found that a target inverse gamma of 1.8 for step 3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one. This process can cost performance. There is an approximation that does not need to know about the background color; see https://bel.fi/alankila/lcd/ and https://bel.fi/alankila/lcd/alpcor.html for details. ATTENTION : Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section \u2018 Subpixel Rendering \u2019. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3 times per pixel: red foreground subpixel to red background subpixel and so on for green and blue. FT_Render_Mode \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Render_Mode_ { FT_RENDER_MODE_NORMAL = 0, FT_RENDER_MODE_LIGHT , FT_RENDER_MODE_MONO , FT_RENDER_MODE_LCD , FT_RENDER_MODE_LCD_V , FT_RENDER_MODE_SDF , FT_RENDER_MODE_MAX } FT_Render_Mode ; /* these constants are deprecated; use the corresponding */ /* ` FT_Render_Mode ` values instead */ # define ft_render_mode_normal FT_RENDER_MODE_NORMAL # define ft_render_mode_mono FT_RENDER_MODE_MONO Render modes supported by FreeType 2. Each mode corresponds to a specific type of scanline conversion performed on the outline. For bitmap fonts and embedded bitmaps the bitmap->pixel_mode field in the FT_GlyphSlotRec structure gives the format of the returned bitmap. All modes except FT_RENDER_MODE_MONO use 256 levels of opacity, indicating pixel coverage. Use linear alpha blending and gamma correction to correctly render non-monochrome glyph bitmaps onto a surface; see FT_Render_Glyph . The FT_RENDER_MODE_SDF is a special render mode that uses up to 256 distance values, indicating the signed distance from the grid position to the nearest outline. values FT_RENDER_MODE_NORMAL Default render mode; it corresponds to 8-bit anti-aliased bitmaps. FT_RENDER_MODE_LIGHT This is equivalent to FT_RENDER_MODE_NORMAL . It is only defined as a separate value because render modes are also used indirectly to define hinting algorithm selectors. See FT_LOAD_TARGET_XXX for details. FT_RENDER_MODE_MONO This mode corresponds to 1-bit bitmaps (with 2 levels of opacity). FT_RENDER_MODE_LCD This mode corresponds to horizontal RGB and BGR subpixel displays like LCD screens. It produces 8-bit bitmaps that are 3 times the width of the original glyph outline in pixels, and which use the FT_PIXEL_MODE_LCD mode. FT_RENDER_MODE_LCD_V This mode corresponds to vertical RGB and BGR subpixel displays (like PDA screens, rotated LCD displays, etc.). It produces 8-bit bitmaps that are 3 times the height of the original glyph outline in pixels and use the FT_PIXEL_MODE_LCD_V mode. FT_RENDER_MODE_SDF This mode corresponds to 8-bit, single-channel signed distance field (SDF) bitmaps. Each pixel in the SDF grid is the value from the pixel's position to the nearest glyph's outline. The distances are calculated from the center of the pixel and are positive if they are filled by the outline (i.e., inside the outline) and negative otherwise. Check the note below on how to convert the output values to usable data. note The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like FT_PIXEL_MODE_MONO . You can use FT_Bitmap_Convert to transform them into 8-bit pixmaps. For FT_RENDER_MODE_SDF the output bitmap buffer contains normalized distances that are packed into unsigned 8-bit values. To get pixel values in floating point representation use the following pseudo-C code for the conversion. // Load glyph and render using FT_RENDER_MODE_SDF, // then use the output buffer as follows. ... FT_Byte buffer = glyph->bitmap->buffer; for pixel in buffer { // `sd` is the signed distance and `spread` is the current spread; // the default spread is 2 and can be changed. float sd = (float)pixel - 128.0f; // Convert to pixel values. sd = ( sd / 128.0f ) * spread; // Store `sd` in a buffer or use as required. } FreeType has two rasterizers for generating SDF, namely: sdf for generating SDF directly from glyph's outline, and bsdf for generating SDF from rasterized bitmaps. Depending on the glyph type (i.e., outline or bitmap), one of the two rasterizers is chosen at runtime and used for generating SDFs. To force the use of bsdf you should render the glyph with any of the FreeType's other rendering modes (e.g., FT_RENDER_MODE_NORMAL ) and then re-render with FT_RENDER_MODE_SDF . There are some issues with stability and possible failures of the SDF renderers (specifically sdf ). The sdf rasterizer is sensitive to really small features (e.g., sharp turns that are less than 1 pixel) and imperfections in the glyph's outline, causing artifacts in the final output. The sdf rasterizer has limited support for handling intersecting contours and cannot handle self-intersecting contours whatsoever. Self-intersection happens when a single connected contour intersects itself at some point; having these in your font definitely poses a problem to the rasterizer and cause artifacts, too. Generating SDF for really small glyphs may result in undesirable output; the pixel grid (which stores distance information) becomes too coarse. Since the output buffer is normalized, precision at smaller spreads is greater than precision at larger spread values because the output range of [0..255] gets mapped to a smaller SDF range. A spread of 2 should be sufficient in most cases. Points (1) and (2) can be avoided by using the bsdf rasterizer, which is more stable than the sdf rasterizer in general. FT_Get_Kerning \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Get_Kerning ( FT_Face face, FT_UInt left_glyph, FT_UInt right_glyph, FT_UInt kern_mode, FT_Vector *akerning ); Return the kerning vector between two glyphs of the same face. input face A handle to a source face object. left_glyph The index of the left glyph in the kern pair. right_glyph The index of the right glyph in the kern pair. kern_mode See FT_Kerning_Mode for more information. Determines the scale and dimension of the returned kerning vector. output akerning The kerning vector. This is either in font units, fractional pixels (26.6 format), or pixels for scalable formats, and in pixels for fixed-sizes formats. return FreeType error code. 0 means success. note Only horizontal layouts (left-to-right & right-to-left) are supported by this method. Other layouts, or more sophisticated kernings, are out of the scope of this API function \u2013 they can be implemented through format-specific interfaces. Kerning for OpenType fonts implemented in a \u2018GPOS\u2019 table is not supported; use FT_HAS_KERNING to find out whether a font has data that can be extracted with FT_Get_Kerning . FT_Kerning_Mode \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Kerning_Mode_ { FT_KERNING_DEFAULT = 0, FT_KERNING_UNFITTED , FT_KERNING_UNSCALED } FT_Kerning_Mode ; /* these constants are deprecated; use the corresponding */ /* ` FT_Kerning_Mode ` values instead */ # define ft_kerning_default FT_KERNING_DEFAULT # define ft_kerning_unfitted FT_KERNING_UNFITTED # define ft_kerning_unscaled FT_KERNING_UNSCALED An enumeration to specify the format of kerning values returned by FT_Get_Kerning . values FT_KERNING_DEFAULT Return grid-fitted kerning distances in 26.6 fractional pixels. FT_KERNING_UNFITTED Return un-grid-fitted kerning distances in 26.6 fractional pixels. FT_KERNING_UNSCALED Return the kerning vector in original font units. note FT_KERNING_DEFAULT returns full pixel values; it also makes FreeType heuristically scale down kerning distances at small ppem values so that they don't become too big. Both FT_KERNING_DEFAULT and FT_KERNING_UNFITTED use the current horizontal scaling factor (as set e.g. with FT_Set_Char_Size ) to convert font units to pixels. FT_Get_Track_Kerning \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Get_Track_Kerning ( FT_Face face, FT_Fixed point_size, FT_Int degree, FT_Fixed * akerning ); Return the track kerning for a given face object at a given size. input face A handle to a source face object. point_size The point size in 16.16 fractional points. degree The degree of tightness. Increasingly negative values represent tighter track kerning, while increasingly positive values represent looser track kerning. Value zero means no track kerning. output akerning The kerning in 16.16 fractional points, to be uniformly applied between all glyphs. return FreeType error code. 0 means success. note Currently, only the Type 1 font driver supports track kerning, using data from AFM files (if attached with FT_Attach_File or FT_Attach_Stream ). Only very few AFM files come with track kerning data; please refer to Adobe's AFM specification for more details. FT_CharMapRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_CharMapRec_ { FT_Face face; FT_Encoding encoding; FT_UShort platform_id; FT_UShort encoding_id; } FT_CharMapRec ; The base charmap structure. fields face A handle to the parent face object. encoding An FT_Encoding tag identifying the charmap. Use this with FT_Select_Charmap . platform_id An ID number describing the platform for the following encoding ID. This comes directly from the TrueType specification and gets emulated for other formats. encoding_id A platform-specific encoding number. This also comes from the TrueType specification and gets emulated similarly. FT_Select_Charmap \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Select_Charmap ( FT_Face face, FT_Encoding encoding ); Select a given charmap by its encoding tag (as listed in freetype.h ). inout face A handle to the source face object. input encoding A handle to the selected encoding. return FreeType error code. 0 means success. note This function returns an error if no charmap in the face corresponds to the encoding queried here. Because many fonts contain more than a single cmap for Unicode encoding, this function has some special code to select the one that covers Unicode best (\u2018best\u2019 in the sense that a UCS-4 cmap is preferred to a UCS-2 cmap). It is thus preferable to FT_Set_Charmap in this case. FT_Set_Charmap \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Charmap ( FT_Face face, FT_CharMap charmap ); Select a given charmap for character code to glyph index mapping. inout face A handle to the source face object. input charmap A handle to the selected charmap. return FreeType error code. 0 means success. note This function returns an error if the charmap is not part of the face (i.e., if it is not listed in the face->charmaps table). It also fails if an OpenType type 14 charmap is selected (which doesn't map character codes to glyph indices at all). FT_Get_Charmap_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Int ) FT_Get_Charmap_Index ( FT_CharMap charmap ); Retrieve index of a given charmap. input charmap A handle to a charmap. return The index into the array of character maps within the face to which charmap belongs. If an error occurs, -1 is returned. FT_Get_Name_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_UInt ) FT_Get_Name_Index ( FT_Face face, const FT_String * glyph_name ); Return the glyph index of a given glyph name. This only works for those faces where FT_HAS_GLYPH_NAMES returns true. input face A handle to the source face object. glyph_name The glyph name. return The glyph index. 0 means \u2018undefined character code\u2019. note Acceptable glyph names might come from the Adobe Glyph List . See FT_Get_Glyph_Name for the inverse functionality. This function has limited capabilities if the config macro FT_CONFIG_OPTION_POSTSCRIPT_NAMES is not defined in ftoption.h : It then works only for fonts that actually embed glyph names (which many recent OpenType fonts do not). FT_Get_Glyph_Name \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Get_Glyph_Name ( FT_Face face, FT_UInt glyph_index, FT_Pointer buffer, FT_UInt buffer_max ); Retrieve the ASCII name of a given glyph in a face. This only works for those faces where FT_HAS_GLYPH_NAMES returns true. input face A handle to a source face object. glyph_index The glyph index. buffer_max The maximum number of bytes available in the buffer. output buffer A pointer to a target buffer where the name is copied to. return FreeType error code. 0 means success. note An error is returned if the face doesn't provide glyph names or if the glyph index is invalid. In all cases of failure, the first byte of buffer is set to 0 to indicate an empty name. The glyph name is truncated to fit within the buffer if it is too long. The returned string is always zero-terminated. Be aware that FreeType reorders glyph indices internally so that glyph index 0 always corresponds to the \u2018missing glyph\u2019 (called \u2018.notdef\u2019). This function has limited capabilities if the config macro FT_CONFIG_OPTION_POSTSCRIPT_NAMES is not defined in ftoption.h : It then works only for fonts that actually embed glyph names (which many recent OpenType fonts do not). FT_Get_Postscript_Name \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( const char * ) FT_Get_Postscript_Name ( FT_Face face ); Retrieve the ASCII PostScript name of a given face, if available. This only works with PostScript, TrueType, and OpenType fonts. input face A handle to the source face object. return A pointer to the face's PostScript name. NULL if unavailable. note The returned pointer is owned by the face and is destroyed with it. For variation fonts, this string changes if you select a different instance, and you have to call FT_Get_PostScript_Name again to retrieve it. FreeType follows Adobe TechNote #5902, \u2018Generating PostScript Names for Fonts Using OpenType Font Variations\u2019. https://download.macromedia.com/pub/developer/opentype/tech-notes/5902.AdobePSNameGeneration.html [Since 2.9] Special PostScript names for named instances are only returned if the named instance is set with FT_Set_Named_Instance (and the font has corresponding entries in its \u2018fvar\u2019 table). If FT_IS_VARIATION returns true, the algorithmically derived PostScript name is provided, not looking up special entries for named instances. FT_Get_FSType_Flags \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_UShort ) FT_Get_FSType_Flags ( FT_Face face ); Return the fsType flags for a font. input face A handle to the source face object. return The fsType flags, see FT_FSTYPE_XXX . note Use this function rather than directly reading the fs_type field in the PS_FontInfoRec structure, which is only guaranteed to return the correct results for Type 1 fonts. since 2.3.8 FT_Get_SubGlyph_Info \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Get_SubGlyph_Info ( FT_GlyphSlot glyph, FT_UInt sub_index, FT_Int *p_index, FT_UInt *p_flags, FT_Int *p_arg1, FT_Int *p_arg2, FT_Matrix *p_transform ); Retrieve a description of a given subglyph. Only use it if glyph->format is FT_GLYPH_FORMAT_COMPOSITE ; an error is returned otherwise. input glyph The source glyph slot. sub_index The index of the subglyph. Must be less than glyph->num_subglyphs . output p_index The glyph index of the subglyph. p_flags The subglyph flags, see FT_SUBGLYPH_FLAG_XXX . p_arg1 The subglyph's first argument (if any). p_arg2 The subglyph's second argument (if any). p_transform The subglyph transformation (if any). return FreeType error code. 0 means success. note The values of *p_arg1 , *p_arg2 , and *p_transform must be interpreted depending on the flags returned in *p_flags . See the OpenType specification for details. https://docs.microsoft.com/en-us/typography/opentype/spec/glyf#composite-glyph-description FT_Face_Internal \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Face_InternalRec_* FT_Face_Internal ; An opaque handle to an FT_Face_InternalRec structure that models the private data of a given FT_Face object. This structure might change between releases of FreeType 2 and is not generally available to client applications. FT_Size_Internal \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_InternalRec_* FT_Size_Internal ; An opaque handle to an FT_Size_InternalRec structure, used to model private data of a given FT_Size object. FT_Slot_Internal \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Slot_InternalRec_* FT_Slot_Internal ; An opaque handle to an FT_Slot_InternalRec structure, used to model private data of a given FT_GlyphSlot object.

They inform client applications of properties of the corresponding face. values FT_FACE_FLAG_SCALABLE The face contains outline glyphs. Note that a face can contain bitmap strikes also, i.e., a face can have both this flag and FT_FACE_FLAG_FIXED_SIZES set. FT_FACE_FLAG_FIXED_SIZES The face contains bitmap strikes. See also the num_fixed_sizes and available_sizes fields of FT_FaceRec . FT_FACE_FLAG_FIXED_WIDTH The face contains fixed-width characters (like Courier, Lucida, MonoType, etc.). FT_FACE_FLAG_SFNT The face uses the SFNT storage scheme. For now, this means TrueType and OpenType. FT_FACE_FLAG_HORIZONTAL The face contains horizontal glyph metrics. This should be set for all common formats. FT_FACE_FLAG_VERTICAL The face contains vertical glyph metrics. This is only available in some formats, not all of them. FT_FACE_FLAG_KERNING The face contains kerning information. If set, the kerning distance can be retrieved using the function FT_Get_Kerning . Otherwise the function always returns the vector (0,0). Note that FreeType doesn't handle kerning data from the SFNT \u2018GPOS\u2019 table (as present in many OpenType fonts). FT_FACE_FLAG_FAST_GLYPHS THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. FT_FACE_FLAG_MULTIPLE_MASTERS The face contains multiple masters and is capable of interpolating between them. Supported formats are Adobe MM, TrueType GX, and OpenType variation fonts. See section \u2018 Multiple Masters \u2019 for API details. FT_FACE_FLAG_GLYPH_NAMES The face contains glyph names, which can be retrieved using FT_Get_Glyph_Name . Note that some TrueType fonts contain broken glyph name tables. Use the function FT_Has_PS_Glyph_Names when needed. FT_FACE_FLAG_EXTERNAL_STREAM Used internally by FreeType to indicate that a face's stream was provided by the client application and should not be destroyed when FT_Done_Face is called. Don't read or test this flag. FT_FACE_FLAG_HINTER The font driver has a hinting machine of its own. For example, with TrueType fonts, it makes sense to use data from the SFNT \u2018gasp\u2019 table only if the native TrueType hinting engine (with the bytecode interpreter) is available and active. FT_FACE_FLAG_CID_KEYED The face is CID-keyed. In that case, the face is not accessed by glyph indices but by CID values. For subsetted CID-keyed fonts this has the consequence that not all index values are a valid argument to FT_Load_Glyph . Only the CID values for which corresponding glyphs in the subsetted font exist make FT_Load_Glyph return successfully; in all other cases you get an FT_Err_Invalid_Argument error. Note that CID-keyed fonts that are in an SFNT wrapper (this is, all OpenType/CFF fonts) don't have this flag set since the glyphs are accessed in the normal way (using contiguous indices); the \u2018CID-ness\u2019 isn't visible to the application. FT_FACE_FLAG_TRICKY The face is \u2018tricky\u2019, this is, it always needs the font format's native hinting engine to get a reasonable result. A typical example is the old Chinese font mingli.ttf (but not mingliu.ttc ) that uses TrueType bytecode instructions to move and scale all of its subglyphs. It is not possible to auto-hint such fonts using FT_LOAD_FORCE_AUTOHINT ; it will also ignore FT_LOAD_NO_HINTING . You have to set both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT to really disable hinting; however, you probably never want this except for demonstration purposes. Currently, there are about a dozen TrueType fonts in the list of tricky fonts; they are hard-coded in file ttobjs.c . FT_FACE_FLAG_COLOR [Since 2.5.1] The face has color glyph tables. See FT_LOAD_COLOR for more information. FT_FACE_FLAG_VARIATION [Since 2.9] Set if the current face (or named instance) has been altered with FT_Set_MM_Design_Coordinates , FT_Set_Var_Design_Coordinates , or FT_Set_Var_Blend_Coordinates . This flag is unset by a call to FT_Set_Named_Instance . FT_FACE_FLAG_SVG [Since 2.12] The face has an \u2018SVG \u2019 OpenType table. FT_FACE_FLAG_SBIX [Since 2.12] The face has an \u2018sbix\u2019 OpenType table and outlines. For such fonts, FT_FACE_FLAG_SCALABLE is not set by default to retain backward compatibility. FT_FACE_FLAG_SBIX_OVERLAY [Since 2.12] The face has an \u2018sbix\u2019 OpenType table where outlines should be drawn on top of bitmap strikes. FT_STYLE_FLAG_XXX \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_STYLE_FLAG_ITALIC ( 1 << 0 ) # define FT_STYLE_FLAG_BOLD ( 1 << 1 ) A list of bit flags to indicate the style of a given face. These are used in the style_flags field of FT_FaceRec . values FT_STYLE_FLAG_ITALIC The face style is italic or oblique. FT_STYLE_FLAG_BOLD The face is bold. note The style information as provided by FreeType is very basic. More details are beyond the scope and should be done on a higher level (for example, by analyzing various fields of the \u2018OS/2\u2019 table in SFNT based fonts).

In this case, the following happens: FreeType looks for a bitmap for the glyph corresponding to the face's current size. If one is found, the function returns. The bitmap data can be accessed from the glyph slot (see note below). If no embedded bitmap is searched for or found, FreeType looks for a scalable outline. If one is found, it is loaded from the font file, scaled to device pixels, then \u2018hinted\u2019 to the pixel grid in order to optimize it. The outline data can be accessed from the glyph slot (see note below). Note that by default the glyph loader doesn't render outlines into bitmaps. The following flags are used to modify this default behaviour to more specific and useful cases. FT_LOAD_NO_SCALE Don't scale the loaded outline glyph but keep it in font units. This flag is also assumed if FT_Size owned by the face was not properly initialized. This flag implies FT_LOAD_NO_HINTING and FT_LOAD_NO_BITMAP , and unsets FT_LOAD_RENDER . If the font is \u2018tricky\u2019 (see FT_FACE_FLAG_TRICKY for more), using FT_LOAD_NO_SCALE usually yields meaningless outlines because the subglyphs must be scaled and positioned with hinting instructions. This can be solved by loading the font without FT_LOAD_NO_SCALE and setting the character size to font->units_per_EM . FT_LOAD_NO_HINTING Disable hinting. This generally generates \u2018blurrier\u2019 bitmap glyphs when the glyphs are rendered in any of the anti-aliased modes. See also the note below. This flag is implied by FT_LOAD_NO_SCALE . FT_LOAD_RENDER Call FT_Render_Glyph after the glyph is loaded. By default, the glyph is rendered in FT_RENDER_MODE_NORMAL mode. This can be overridden by FT_LOAD_TARGET_XXX or FT_LOAD_MONOCHROME . This flag is unset by FT_LOAD_NO_SCALE . FT_LOAD_NO_BITMAP Ignore bitmap strikes when loading. Bitmap-only fonts ignore this flag. FT_LOAD_NO_SCALE always sets this flag. FT_LOAD_SBITS_ONLY [Since 2.12] This is the opposite of FT_LOAD_NO_BITMAP , more or less: FT_Load_Glyph returns FT_Err_Invalid_Argument if the face contains a bitmap strike for the given size (or the strike selected by FT_Select_Size ) but there is no glyph in the strike. Note that this load flag was part of FreeType since version 2.0.6 but previously tagged as internal. FT_LOAD_VERTICAL_LAYOUT Load the glyph for vertical text layout. In particular, the advance value in the FT_GlyphSlotRec structure is set to the vertAdvance value of the metrics field. In case FT_HAS_VERTICAL doesn't return true, you shouldn't use this flag currently. Reason is that in this case vertical metrics get synthesized, and those values are not always consistent across various font formats. FT_LOAD_FORCE_AUTOHINT Prefer the auto-hinter over the font's native hinter. See also the note below. FT_LOAD_PEDANTIC Make the font driver perform pedantic verifications during glyph loading and hinting. This is mostly used to detect broken glyphs in fonts. By default, FreeType tries to handle broken fonts also. In particular, errors from the TrueType bytecode engine are not passed to the application if this flag is not set; this might result in partially hinted or distorted glyphs in case a glyph's bytecode is buggy. FT_LOAD_NO_RECURSE Don't load composite glyphs recursively. Instead, the font driver fills the num_subglyph and subglyphs values of the glyph slot; it also sets glyph->format to FT_GLYPH_FORMAT_COMPOSITE . The description of subglyphs can then be accessed with FT_Get_SubGlyph_Info . Don't use this flag for retrieving metrics information since some font drivers only return rudimentary data. This flag implies FT_LOAD_NO_SCALE and FT_LOAD_IGNORE_TRANSFORM . FT_LOAD_IGNORE_TRANSFORM Ignore the transform matrix set by FT_Set_Transform . FT_LOAD_MONOCHROME This flag is used with FT_LOAD_RENDER to indicate that you want to render an outline glyph to a 1-bit monochrome bitmap glyph, with 8 pixels packed into each byte of the bitmap data. Note that this has no effect on the hinting algorithm used. You should rather use FT_LOAD_TARGET_MONO so that the monochrome-optimized hinting algorithm is used. FT_LOAD_LINEAR_DESIGN Keep linearHoriAdvance and linearVertAdvance fields of FT_GlyphSlotRec in font units. See FT_GlyphSlotRec for details. FT_LOAD_NO_AUTOHINT Disable the auto-hinter. See also the note below. FT_LOAD_COLOR Load colored glyphs. FreeType searches in the following order; there are slight differences depending on the font format. [Since 2.5] Load embedded color bitmap images (provided FT_LOAD_NO_BITMAP is not set). The resulting color bitmaps, if available, have the FT_PIXEL_MODE_BGRA format, with pre-multiplied color channels. If the flag is not set and color bitmaps are found, they are converted to 256-level gray bitmaps, using the FT_PIXEL_MODE_GRAY format. [Since 2.12] If the glyph index maps to an entry in the face's \u2018SVG \u2019 table, load the associated SVG document from this table and set the format field of FT_GlyphSlotRec to FT_GLYPH_FORMAT_SVG . Note that FreeType itself can't render SVG documents; however, the library provides hooks to seamlessly integrate an external renderer. See sections \u2018 The SVG driver \u2019 and \u2018 OpenType SVG Fonts \u2019 for more. [Since 2.10, experimental] If the glyph index maps to an entry in the face's \u2018COLR\u2019 table with a \u2018CPAL\u2019 palette table (as defined in the OpenType specification), make FT_Render_Glyph provide a default blending of the color glyph layers associated with the glyph index, using the same bitmap format as embedded color bitmap images. This is mainly for convenience and works only for glyphs in \u2018COLR\u2019 v0 tables (or glyphs in \u2018COLR\u2019 v1 tables that exclusively use v0 features). For full control of color layers use FT_Get_Color_Glyph_Layer and FreeType's color functions like FT_Palette_Select instead of setting FT_LOAD_COLOR for rendering so that the client application can handle blending by itself. FT_LOAD_COMPUTE_METRICS [Since 2.6.1] Compute glyph metrics from the glyph data, without the use of bundled metrics tables (for example, the \u2018hdmx\u2019 table in TrueType fonts). This flag is mainly used by font validating or font editing applications, which need to ignore, verify, or edit those tables. Currently, this flag is only implemented for TrueType fonts. FT_LOAD_BITMAP_METRICS_ONLY [Since 2.7.1] Request loading of the metrics and bitmap image information of a (possibly embedded) bitmap glyph without allocating or copying the bitmap image data itself. No effect if the target glyph is not a bitmap image. This flag unsets FT_LOAD_RENDER . FT_LOAD_CROP_BITMAP Ignored. Deprecated. FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH Ignored. Deprecated. note By default, hinting is enabled and the font's native hinter (see FT_FACE_FLAG_HINTER ) is preferred over the auto-hinter. You can disable hinting by setting FT_LOAD_NO_HINTING or change the precedence by setting FT_LOAD_FORCE_AUTOHINT . You can also set FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be used at all. See the description of FT_FACE_FLAG_TRICKY for a special exception (affecting only a handful of Asian fonts). Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See FT_LOAD_TARGET_XXX for details. Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results. FT_LOAD_TARGET_XXX \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_LOAD_TARGET_( x ) ( FT_STATIC_CAST( FT_Int32 , (x) & 15 ) << 16 ) # define FT_LOAD_TARGET_NORMAL FT_LOAD_TARGET_( FT_RENDER_MODE_NORMAL ) # define FT_LOAD_TARGET_LIGHT FT_LOAD_TARGET_( FT_RENDER_MODE_LIGHT ) # define FT_LOAD_TARGET_MONO FT_LOAD_TARGET_( FT_RENDER_MODE_MONO ) # define FT_LOAD_TARGET_LCD FT_LOAD_TARGET_( FT_RENDER_MODE_LCD ) # define FT_LOAD_TARGET_LCD_V FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V ) A list of values to select a specific hinting algorithm for the hinter. You should OR one of these values to your load_flags when calling FT_Load_Glyph . Note that a font's native hinters may ignore the hinting algorithm you have specified (e.g., the TrueType bytecode interpreter). You can set FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used. values FT_LOAD_TARGET_NORMAL The default hinting algorithm, optimized for standard gray-level rendering. For monochrome output, use FT_LOAD_TARGET_MONO instead. FT_LOAD_TARGET_LIGHT A lighter hinting algorithm for gray-level modes. Many generated glyphs are fuzzier but better resemble their original shape. This is achieved by snapping glyphs to the pixel grid only vertically (Y-axis), as is done by FreeType's new CFF engine or Microsoft's ClearType font renderer. This preserves inter-glyph spacing in horizontal text. The snapping is done either by the native font driver, if the driver itself and the font support it, or by the auto-hinter. Advance widths are rounded to integer values; however, using the lsb_delta and rsb_delta fields of FT_GlyphSlotRec , it is possible to get fractional advance widths for subpixel positioning (which is recommended to use). If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active, TrueType-like metrics are used to make this mode behave similarly as in unpatched FreeType versions between 2.4.6 and 2.7.1 (inclusive). FT_LOAD_TARGET_MONO Strong hinting algorithm that should only be used for monochrome output. The result is probably unpleasant if the glyph is rendered in non-monochrome modes. Note that for outline fonts only the TrueType font driver has proper monochrome hinting support, provided the TTFs contain hints for B/W rendering (which most fonts no longer provide). If these conditions are not met it is very likely that you get ugly results at smaller sizes. FT_LOAD_TARGET_LCD A variant of FT_LOAD_TARGET_LIGHT optimized for horizontally decimated LCD displays. FT_LOAD_TARGET_LCD_V A variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays. note You should use only one of the FT_LOAD_TARGET_XXX values in your load_flags . They can't be ORed. If FT_LOAD_RENDER is also set, the glyph is rendered in the corresponding mode (i.e., the mode that matches the used algorithm best). An exception is FT_LOAD_TARGET_MONO since it implies FT_LOAD_MONOCHROME . You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the \u2018light\u2019 hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like FT_Load_Glyph( face, glyph_index, load_flags | FT_LOAD_TARGET_LIGHT ); FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD ); In general, you should stick with one rendering mode. For example, switching between FT_LOAD_TARGET_NORMAL and FT_LOAD_TARGET_MONO enforces a lot of recomputation for TrueType fonts, which is slow. Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits.

FT_FSTYPE_RESTRICTED_LICENSE_EMBEDDING Fonts that have only this bit set must not be modified, embedded or exchanged in any manner without first obtaining permission of the font software copyright owner. FT_FSTYPE_PREVIEW_AND_PRINT_EMBEDDING The font may be embedded and temporarily loaded on the remote system. Documents containing Preview & Print fonts must be opened \u2018read-only\u2019; no edits can be applied to the document. FT_FSTYPE_EDITABLE_EMBEDDING The font may be embedded but must only be installed temporarily on other systems. In contrast to Preview & Print fonts, documents containing editable fonts may be opened for reading, editing is permitted, and changes may be saved. FT_FSTYPE_NO_SUBSETTING The font may not be subsetted prior to embedding. FT_FSTYPE_BITMAP_EMBEDDING_ONLY Only bitmaps contained in the font may be embedded; no outline data may be embedded. If there are no bitmaps available in the font, then the font is unembeddable. note The flags are ORed together, thus more than a single value can be returned. While the fsType flags can indicate that a font may be embedded, a license with the font vendor may be separately required to use the font in this way.

FT_Error \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef int FT_Error ; The FreeType error code type. A value of 0 is always interpreted as a successful operation. FT_Fixed \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef signed long FT_Fixed ; This type is used to store 16.16 fixed-point values, like scaling values or matrix coefficients.

FT_Vector \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Vector_ { FT_Pos x; FT_Pos y; } FT_Vector ; A simple structure used to store a 2D vector; coordinates are of the FT_Pos type. fields x The horizontal coordinate. y The vertical coordinate. FT_BBox \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_BBox_ { FT_Pos xMin, yMin; FT_Pos xMax, yMax; } FT_BBox ; A structure used to hold an outline's bounding box, i.e., the coordinates of its extrema in the horizontal and vertical directions. fields xMin The horizontal minimum (left-most). yMin The vertical minimum (bottom-most). xMax The horizontal maximum (right-most). yMax The vertical maximum (top-most). note The bounding box is specified with the coordinates of the lower left and the upper right corner. In PostScript, those values are often called (llx,lly) and (urx,ury), respectively. If yMin is negative, this value gives the glyph's descender. Otherwise, the glyph doesn't descend below the baseline. Similarly, if ymax is positive, this value gives the glyph's ascender. xMin gives the horizontal distance from the glyph's origin to the left edge of the glyph's bounding box. If xMin is negative, the glyph extends to the left of the origin. FT_Matrix \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Matrix_ { FT_Fixed xx, xy; FT_Fixed yx, yy; } FT_Matrix ; A simple structure used to store a 2x2 matrix.

FT_Data \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Data_ { const FT_Byte * pointer; FT_UInt length; } FT_Data ; Read-only binary data represented as a pointer and a length. fields pointer The data. length The length of the data in bytes. FT_MAKE_TAG \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). # define FT_MAKE_TAG ( _x1, _x2, _x3, _x4 ) \\ ( ( FT_STATIC_BYTE_CAST( FT_Tag , _x1 ) << 24 ) | \\ ( FT_STATIC_BYTE_CAST( FT_Tag , _x2 ) << 16 ) | \\ ( FT_STATIC_BYTE_CAST( FT_Tag , _x3 ) << 8 ) | \\ FT_STATIC_BYTE_CAST( FT_Tag , _x4 ) ) This macro converts four-letter tags that are used to label TrueType tables into an FT_Tag type, to be used within FreeType. note The produced values must be 32-bit integers. Don't redefine this macro. FT_Generic \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Generic_ { void * data; FT_Generic_Finalizer finalizer; } FT_Generic ; Client applications often need to associate their own data to a variety of FreeType core objects. For example, a text layout API might want to associate a glyph cache to a given size object. Some FreeType object contains a generic field, of type FT_Generic , which usage is left to client applications and font servers. It can be used to store a pointer to client-specific data, as well as the address of a \u2018finalizer\u2019 function, which will be called by FreeType when the object is destroyed (for example, the previous client example would put the address of the glyph cache destructor in the finalizer field). fields data A typeless pointer to any client-specified data. This field is completely ignored by the FreeType library. finalizer A pointer to a \u2018generic finalizer\u2019 function, which will be called when the object is destroyed. If this field is set to NULL , no code will be called. FT_Generic_Finalizer \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef void (* FT_Generic_Finalizer )( void * object ); Describe a function used to destroy the \u2018client\u2019 data of any FreeType object. See the description of the FT_Generic type for details of usage. input The address of the FreeType object that is under finalization. Its client data is accessed through its generic field. FT_Bitmap \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Bitmap_ { unsigned int rows; unsigned int width; int pitch; unsigned char * buffer; unsigned short num_grays; unsigned char pixel_mode; unsigned char palette_mode; void * palette; } FT_Bitmap ; A structure used to describe a bitmap or pixmap to the raster. Note that we now manage pixmaps of various depths through the pixel_mode field. fields rows The number of bitmap rows. width The number of pixels in bitmap row. pitch The pitch's absolute value is the number of bytes taken by one bitmap row, including padding. However, the pitch is positive when the bitmap has a \u2018down\u2019 flow, and negative when it has an \u2018up\u2019 flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row. Note that \u2018padding\u2019 means the alignment of a bitmap to a byte border, and FreeType functions normally align to the smallest possible integer value. For the B/W rasterizer, pitch is always an even number. To change the pitch of a bitmap (say, to make it a multiple of 4), use FT_Bitmap_Convert . Alternatively, you might use callback functions to directly render to the application's surface; see the file example2.cpp in the tutorial for a demonstration. buffer A typeless pointer to the bitmap buffer. This value should be aligned on 32-bit boundaries in most cases. num_grays This field is only used with FT_PIXEL_MODE_GRAY ; it gives the number of gray levels used in the bitmap. pixel_mode The pixel mode, i.e., how pixel bits are stored. See FT_Pixel_Mode for possible values. palette_mode This field is intended for paletted pixel modes; it indicates how the palette is stored. Not used currently. palette A typeless pointer to the bitmap palette; this field is intended for paletted pixel modes. Not used currently. FT_Pixel_Mode \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef enum FT_Pixel_Mode_ { FT_PIXEL_MODE_NONE = 0, FT_PIXEL_MODE_MONO , FT_PIXEL_MODE_GRAY , FT_PIXEL_MODE_GRAY2 , FT_PIXEL_MODE_GRAY4 , FT_PIXEL_MODE_LCD , FT_PIXEL_MODE_LCD_V , FT_PIXEL_MODE_BGRA , FT_PIXEL_MODE_MAX /* do not remove */ } FT_Pixel_Mode ; /* these constants are deprecated; use the corresponding ` FT_Pixel_Mode ` */ /* values instead. */ # define ft_pixel_mode_none FT_PIXEL_MODE_NONE # define ft_pixel_mode_mono FT_PIXEL_MODE_MONO # define ft_pixel_mode_grays FT_PIXEL_MODE_GRAY # define ft_pixel_mode_pal2 FT_PIXEL_MODE_GRAY2 # define ft_pixel_mode_pal4 FT_PIXEL_MODE_GRAY4 An enumeration type used to describe the format of pixels in a given bitmap. Note that additional formats may be added in the future. values FT_PIXEL_MODE_NONE Value 0 is reserved. FT_PIXEL_MODE_MONO A monochrome bitmap, using 1 bit per pixel. Note that pixels are stored in most-significant order (MSB), which means that the left-most pixel in a byte has value 128. FT_PIXEL_MODE_GRAY An 8-bit bitmap, generally used to represent anti-aliased glyph images. Each pixel is stored in one byte. Note that the number of \u2018gray\u2019 levels is stored in the num_grays field of the FT_Bitmap structure (it generally is 256). FT_PIXEL_MODE_GRAY2 A 2-bit per pixel bitmap, used to represent embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven't found a single font using this format, however. FT_PIXEL_MODE_GRAY4 A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven't found a single font using this format, however. FT_PIXEL_MODE_LCD An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on LCD displays; the bitmap is three times wider than the original glyph image. See also FT_RENDER_MODE_LCD . FT_PIXEL_MODE_LCD_V An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on rotated LCD displays; the bitmap is three times taller than the original glyph image. See also FT_RENDER_MODE_LCD_V . FT_PIXEL_MODE_BGRA [Since 2.5] An image with four 8-bit channels per pixel, representing a color image (such as emoticons) with alpha channel. For each pixel, the format is BGRA, which means, the blue channel comes first in memory. The color channels are pre-multiplied and in the sRGB colorspace. For example, full red at half-translucent opacity will be represented as \u201800,00,80,80\u2019, not \u201800,00,FF,80\u2019. See also FT_LOAD_COLOR . FT_Glyph_Format \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef enum FT_Glyph_Format_ { FT_IMAGE_TAG ( FT_GLYPH_FORMAT_NONE , 0, 0, 0, 0 ), FT_IMAGE_TAG ( FT_GLYPH_FORMAT_COMPOSITE , 'c', 'o', 'm', 'p' ), FT_IMAGE_TAG ( FT_GLYPH_FORMAT_BITMAP , 'b', 'i', 't', 's' ), FT_IMAGE_TAG ( FT_GLYPH_FORMAT_OUTLINE , 'o', 'u', 't', 'l' ), FT_IMAGE_TAG ( FT_GLYPH_FORMAT_PLOTTER , 'p', 'l', 'o', 't' ), FT_IMAGE_TAG ( FT_GLYPH_FORMAT_SVG , 'S', 'V', 'G', ' ' ) } FT_Glyph_Format ; /* these constants are deprecated; use the corresponding */ /* ` FT_Glyph_Format ` values instead. */ # define ft_glyph_format_none FT_GLYPH_FORMAT_NONE # define ft_glyph_format_composite FT_GLYPH_FORMAT_COMPOSITE # define ft_glyph_format_bitmap FT_GLYPH_FORMAT_BITMAP # define ft_glyph_format_outline FT_GLYPH_FORMAT_OUTLINE # define ft_glyph_format_plotter FT_GLYPH_FORMAT_PLOTTER An enumeration type used to describe the format of a given glyph image. Note that this version of FreeType only supports two image formats, even though future font drivers will be able to register their own format. values FT_GLYPH_FORMAT_NONE The value 0 is reserved. FT_GLYPH_FORMAT_COMPOSITE The glyph image is a composite of several other images. This format is only used with FT_LOAD_NO_RECURSE , and is used to report compound glyphs (like accented characters). FT_GLYPH_FORMAT_BITMAP The glyph image is a bitmap, and can be described as an FT_Bitmap . You generally need to access the bitmap field of the FT_GlyphSlotRec structure to read it. FT_GLYPH_FORMAT_OUTLINE The glyph image is a vectorial outline made of line segments and Bezier arcs; it can be described as an FT_Outline ; you generally want to access the outline field of the FT_GlyphSlotRec structure to read it. FT_GLYPH_FORMAT_PLOTTER The glyph image is a vectorial path with no inside and outside contours. Some Type 1 fonts, like those in the Hershey family, contain glyphs in this format. These are described as FT_Outline , but FreeType isn't currently capable of rendering them correctly. FT_GLYPH_FORMAT_SVG [Since 2.12] The glyph is represented by an SVG document in the \u2018SVG \u2019 table.

Note that all types and functions begin with the FTC_ prefix. The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme: First, available or installed font faces are uniquely identified by FTC_FaceID values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way. Second, the cache calls, only when needed, a client-provided function to convert an FTC_FaceID into a new FT_Face object. The latter is then completely managed by the cache, including its termination through FT_Done_Face . To monitor termination of face objects, the finalizer callback in the generic field of the FT_Face object can be used, which might also be used to store the FTC_FaceID of the face. Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call FT_New_Face . However, more complex schemes are also possible. Note that for the cache to work correctly, the face ID values must be persistent , which means that the contents they point to should not change at runtime, or that their value should not become invalid. If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call FTC_Manager_RemoveFaceID as soon as possible, to let the cache get rid of any references to the old FTC_FaceID it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes. To use the cache, start with calling FTC_Manager_New to create a new FTC_Manager object, which models a single cache instance. You can then look up FT_Face and FT_Size objects with FTC_Manager_LookupFace and FTC_Manager_LookupSize , respectively. If you want to use the charmap caching, call FTC_CMapCache_New , then later use FTC_CMapCache_Lookup to perform the equivalent of FT_Get_Char_Index , only much faster. If you want to use the FT_Glyph caching, call FTC_ImageCache_New , then later use FTC_ImageCache_Lookup to retrieve the corresponding FT_Glyph objects from the cache. If you need lots of small bitmaps, it is much more memory efficient to call FTC_SBitCache_New followed by FTC_SBitCache_Lookup . This returns FTC_SBitRec structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers). We hope to also provide a kerning cache in the near future. FTC_Manager \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ManagerRec_* FTC_Manager ; This object corresponds to one instance of the cache-subsystem. It is used to cache one or more FT_Face objects, along with corresponding FT_Size objects. The manager intentionally limits the total number of opened FT_Face and FT_Size objects to control memory usage. See the max_faces and max_sizes parameters of FTC_Manager_New . The manager is also used to cache \u2018nodes\u2019 of various types while limiting their total memory usage. All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones. FTC_FaceID \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef FT_Pointer FTC_FaceID ; An opaque pointer type that is used to identity face objects. The contents of such objects is application-dependent. These pointers are typically used to point to a user-defined structure containing a font file path, and face index. note Never use NULL as a valid FTC_FaceID . Face IDs are passed by the client to the cache manager that calls, when needed, the FTC_Face_Requester to translate them into new FT_Face objects. If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call FTC_Manager_RemoveFaceID before any other cache function. Failure to do so will result in incorrect behaviour or even memory leaks and crashes. FTC_Face_Requester \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef FT_Error (* FTC_Face_Requester )( FTC_FaceID face_id, FT_Library library, FT_Pointer req_data, FT_Face * aface ); A callback function provided by client applications. It is used by the cache manager to translate a given FTC_FaceID into a new valid FT_Face object, on demand. input face_id The face ID to resolve. library A handle to a FreeType library object. req_data Application-provided request data (see note below). output aface A new FT_Face handle. return FreeType error code. 0 means success. note The third parameter req_data is the same as the one passed by the client when FTC_Manager_New is called. The face requester should not perform funny things on the returned face object, like creating a new FT_Size for it, or setting a transformation through FT_Set_Transform ! FTC_Manager_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_New ( FT_Library library, FT_UInt max_faces, FT_UInt max_sizes, FT_ULong max_bytes, FTC_Face_Requester requester, FT_Pointer req_data, FTC_Manager *amanager ); Create a new cache manager. input library The parent FreeType library handle to use. max_faces Maximum number of opened FT_Face objects managed by this cache instance.

Use 0 for defaults. Note that this value does not account for managed FT_Face and FT_Size objects. requester An application-provided callback used to translate face IDs into real FT_Face objects. req_data A generic pointer that is passed to the requester each time it is called (see FTC_Face_Requester ). output amanager A handle to a new manager object. 0 in case of failure. return FreeType error code. 0 means success. FTC_Manager_Reset \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_Reset ( FTC_Manager manager ); Empty a given cache manager. This simply gets rid of all the currently cached FT_Face and FT_Size objects within the manager. inout manager A handle to the manager. FTC_Manager_Done \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_Done ( FTC_Manager manager ); Destroy a given manager after emptying it. input manager A handle to the target cache manager object. FTC_Manager_LookupFace \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_LookupFace ( FTC_Manager manager, FTC_FaceID face_id, FT_Face *aface ); Retrieve the FT_Face object that corresponds to a given face ID through a cache manager. input manager A handle to the cache manager. face_id The ID of the face object. output aface A handle to the face object. return FreeType error code. 0 means success. note The returned FT_Face object is always owned by the manager. You should never try to discard it yourself. The FT_Face object doesn't necessarily have a current size object (i.e., face->size can be 0). If you need a specific \u2018font size\u2019, use FTC_Manager_LookupSize instead. Never change the face's transformation matrix (i.e., never call the FT_Set_Transform function) on a returned face! If you need to transform glyphs, do it yourself after glyph loading. When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed. If a lookup fails with FT_Err_Out_Of_Memory the cache has already been completely flushed, and still no memory was available for the operation. FTC_Manager_LookupSize \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_LookupSize ( FTC_Manager manager, FTC_Scaler scaler, FT_Size *asize ); Retrieve the FT_Size object that corresponds to a given FTC_ScalerRec pointer through a cache manager. input manager A handle to the cache manager. scaler A scaler handle. output asize A handle to the size object. return FreeType error code. 0 means success. note The returned FT_Size object is always owned by the manager. You should never try to discard it by yourself. You can access the parent FT_Face object simply as size->face if you need it. Note that this object is also owned by the manager. note When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed. If a lookup fails with FT_Err_Out_Of_Memory the cache has already been completely flushed, and still no memory is available for the operation. FTC_Manager_RemoveFaceID \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_RemoveFaceID ( FTC_Manager manager, FTC_FaceID face_id ); A special function used to indicate to the cache manager that a given FTC_FaceID is no longer valid, either because its content changed, or because it was deallocated or uninstalled. input manager The cache manager handle. face_id The FTC_FaceID to be removed. note This function flushes all nodes from the cache corresponding to this face_id , with the exception of nodes with a non-null reference count. Such nodes are however modified internally so as to never appear in later lookups with the same face_id value, and to be immediately destroyed when released by all their users. FTC_Node \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_NodeRec_* FTC_Node ; An opaque handle to a cache node object. Each cache node is reference-counted. A node with a count of 0 might be flushed out of a full cache whenever a lookup request is performed. If you look up nodes, you have the ability to \u2018acquire\u2019 them, i.e., to increment their reference count. This will prevent the node from being flushed out of the cache until you explicitly \u2018release\u2019 it (see FTC_Node_Unref ). See also FTC_SBitCache_Lookup and FTC_ImageCache_Lookup . FTC_Node_Unref \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Node_Unref ( FTC_Node node, FTC_Manager manager ); Decrement a cache node's internal reference count. When the count reaches 0, it is not destroyed but becomes eligible for subsequent cache flushes. input node The cache node handle. manager The cache manager handle. FTC_ImageCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ImageCacheRec_* FTC_ImageCache ; A handle to a glyph image cache object. They are designed to hold many distinct glyph images while not exceeding a certain memory threshold. FTC_ImageCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_ImageCache_New ( FTC_Manager manager, FTC_ImageCache *acache ); Create a new glyph image cache. input manager The parent manager for the image cache. output acache A handle to the new glyph image cache object. return FreeType error code. 0 means success. FTC_ImageCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_ImageCache_Lookup ( FTC_ImageCache cache, FTC_ImageType type, FT_UInt gindex, FT_Glyph *aglyph, FTC_Node *anode ); Retrieve a given glyph image from a glyph image cache. input cache A handle to the source glyph image cache. type A pointer to a glyph image type descriptor. gindex The glyph index to retrieve. output aglyph The corresponding FT_Glyph object. 0 in case of failure. anode Used to return the address of the corresponding cache node after incrementing its reference count (see note below). return FreeType error code. 0 means success. note The returned glyph is owned and managed by the glyph image cache. Never try to transform or discard it manually! You can however create a copy with FT_Glyph_Copy and modify the new one. If anode is not NULL , it receives the address of the cache node containing the glyph image, after increasing its reference count. This ensures that the node (as well as the FT_Glyph ) will always be kept in the cache until you call FTC_Node_Unref to \u2018release\u2019 it. If anode is NULL , the cache node is left unchanged, which means that the FT_Glyph could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent! FTC_SBit \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_SBitRec_* FTC_SBit ; A handle to a small bitmap descriptor. See the FTC_SBitRec structure for details. FTC_SBitCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_SBitCacheRec_* FTC_SBitCache ; A handle to a small bitmap cache. These are special cache objects used to store small glyph bitmaps (and anti-aliased pixmaps) in a much more efficient way than the traditional glyph image cache implemented by FTC_ImageCache . FTC_SBitCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_SBitCache_New ( FTC_Manager manager, FTC_SBitCache *acache ); Create a new cache to store small glyph bitmaps. input manager A handle to the source cache manager. output acache A handle to the new sbit cache. NULL in case of error. return FreeType error code. 0 means success. FTC_SBitCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_SBitCache_Lookup ( FTC_SBitCache cache, FTC_ImageType type, FT_UInt gindex, FTC_SBit *sbit, FTC_Node *anode ); Look up a given small glyph bitmap in a given sbit cache and \u2018lock\u2019 it to prevent its flushing from the cache until needed. input cache A handle to the source sbit cache. type A pointer to the glyph image type descriptor. gindex The glyph index. output sbit A handle to a small bitmap descriptor. anode Used to return the address of the corresponding cache node after incrementing its reference count (see note below). return FreeType error code. 0 means success. note The small bitmap descriptor and its bit buffer are owned by the cache and should never be freed by the application. They might as well disappear from memory on the next cache lookup, so don't treat them as persistent data. The descriptor's buffer field is set to 0 to indicate a missing glyph bitmap. If anode is not NULL , it receives the address of the cache node containing the bitmap, after increasing its reference count. This ensures that the node (as well as the image) will always be kept in the cache until you call FTC_Node_Unref to \u2018release\u2019 it. If anode is NULL , the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent! FTC_CMapCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_CMapCacheRec_* FTC_CMapCache ; An opaque handle used to model a charmap cache. This cache is to hold character codes -> glyph indices mappings. FTC_CMapCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_CMapCache_New ( FTC_Manager manager, FTC_CMapCache *acache ); Create a new charmap cache. input manager A handle to the cache manager. output acache A new cache handle. NULL in case of error. return FreeType error code. 0 means success. note Like all other caches, this one will be destroyed with the cache manager. FTC_CMapCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_UInt ) FTC_CMapCache_Lookup ( FTC_CMapCache cache, FTC_FaceID face_id, FT_Int cmap_index, FT_UInt32 char_code ); Translate a character code into a glyph index, using the charmap cache. input cache A charmap cache handle. face_id The source face ID. cmap_index The index of the charmap in the source face. Any negative value means to use the cache FT_Face 's default charmap. char_code The character code (in the corresponding charmap). return Glyph index. 0 means \u2018no glyph\u2019. FTC_ScalerRec \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ScalerRec_ { FTC_FaceID face_id; FT_UInt width; FT_UInt height; FT_Int pixel; FT_UInt x_res; FT_UInt y_res; } FTC_ScalerRec ; A structure used to describe a given character size in either pixels or points to the cache manager. See FTC_Manager_LookupSize . fields face_id The source face ID. width The character width. height The character height. pixel A Boolean. If 1, the width and height fields are interpreted as integer pixel character sizes. Otherwise, they are expressed as 1/64 of points. x_res Only used when pixel is value 0 to indicate the horizontal resolution in dpi. y_res Only used when pixel is value 0 to indicate the vertical resolution in dpi. note This type is mainly used to retrieve FT_Size objects through the cache manager. FTC_Scaler \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ScalerRec_* FTC_Scaler ; A handle to an FTC_ScalerRec structure. FTC_ImageTypeRec \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ImageTypeRec_ { FTC_FaceID face_id; FT_UInt width; FT_UInt height; FT_Int32 flags; } FTC_ImageTypeRec ; A structure used to model the type of images in a glyph cache. fields face_id The face ID. width The width in pixels. height The height in pixels. flags The load flags, as in FT_Load_Glyph . FTC_ImageType \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ImageTypeRec_* FTC_ImageType ; A handle to an FTC_ImageTypeRec structure.

The CFF driver's module name is \u2018cff\u2019. Available properties are hinting-engine , no-stem-darkening , darkening-parameters , and random-seed , as documented in the \u2018 Driver properties \u2019 section. Hinting and anti-aliasing principles of the new engine The rasterizer is positioning horizontal features (e.g., ascender height & x-height, or crossbars) on the pixel grid and minimizing the amount of anti-aliasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, \u2018anti-aliasing\u2019 means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance. There are two principles behind this approach. 1) No hinting in the horizontal direction: Unlike \u2018superhinted\u2019 TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is \u2018faithful to the design\u2019 in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied. One of the reasons to not hint horizontally is anti-aliasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale anti-aliasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would. 2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of \u2153 pixels) is less of a problem. On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called \u2018blue zones\u2019) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling. Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be \u2018captured\u2019 and are aligned to that zone.

FT_Glyph_BBox_Mode \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). typedef enum FT_Glyph_BBox_Mode_ { FT_GLYPH_BBOX_UNSCALED = 0, FT_GLYPH_BBOX_SUBPIXELS = 0, FT_GLYPH_BBOX_GRIDFIT = 1, FT_GLYPH_BBOX_TRUNCATE = 2, FT_GLYPH_BBOX_PIXELS = 3 } FT_Glyph_BBox_Mode ; /* these constants are deprecated; use the corresponding */ /* ` FT_Glyph_BBox_Mode ` values instead */ # define ft_glyph_bbox_unscaled FT_GLYPH_BBOX_UNSCALED # define ft_glyph_bbox_subpixels FT_GLYPH_BBOX_SUBPIXELS # define ft_glyph_bbox_gridfit FT_GLYPH_BBOX_GRIDFIT # define ft_glyph_bbox_truncate FT_GLYPH_BBOX_TRUNCATE # define ft_glyph_bbox_pixels FT_GLYPH_BBOX_PIXELS The mode how the values of FT_Glyph_Get_CBox are returned. values FT_GLYPH_BBOX_UNSCALED Return unscaled font units. FT_GLYPH_BBOX_SUBPIXELS Return unfitted 26.6 coordinates. FT_GLYPH_BBOX_GRIDFIT Return grid-fitted 26.6 coordinates. FT_GLYPH_BBOX_TRUNCATE Return coordinates in integer pixels. FT_GLYPH_BBOX_PIXELS Return grid-fitted pixel coordinates. FT_Glyph_Get_CBox \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). FT_EXPORT( void ) FT_Glyph_Get_CBox ( FT_Glyph glyph, FT_UInt bbox_mode, FT_BBox *acbox ); Return a glyph's \u2018control box\u2019. The control box encloses all the outline's points, including Bezier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline that contains Bezier outside arcs). Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the \u2018ftbbox\u2019 component, which is dedicated to this single task. input glyph A handle to the source glyph object. mode The mode that indicates how to interpret the returned bounding box values. output acbox The glyph coordinate bounding box. Coordinates are expressed in 1/64 of pixels if it is grid-fitted. note Coordinates are relative to the glyph origin, using the y upwards convention. If the glyph has been loaded with FT_LOAD_NO_SCALE , bbox_mode must be set to FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6 pixel format. The value FT_GLYPH_BBOX_SUBPIXELS is another name for this constant. If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE , the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units. Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as: width = bbox.xMax - bbox.xMin; height = bbox.yMax - bbox.yMin; Note also that for 26.6 coordinates, if bbox_mode is set to FT_GLYPH_BBOX_GRIDFIT , the coordinates will also be grid-fitted, which corresponds to: bbox.xMin = FLOOR(bbox.xMin); bbox.yMin = FLOOR(bbox.yMin); bbox.xMax = CEILING(bbox.xMax); bbox.yMax = CEILING(bbox.yMax); To get the bbox in pixel coordinates, set bbox_mode to FT_GLYPH_BBOX_TRUNCATE . To get the bbox in grid-fitted pixel coordinates, set bbox_mode to FT_GLYPH_BBOX_PIXELS . FT_Glyph_To_Bitmap \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). FT_EXPORT( FT_Error ) FT_Glyph_To_Bitmap ( FT_Glyph * the_glyph, FT_Render_Mode render_mode, const FT_Vector * origin, FT_Bool destroy ); Convert a given glyph object to a bitmap glyph object. inout the_glyph A pointer to a handle to the target glyph. input render_mode An enumeration that describes how the data is rendered. origin A pointer to a vector used to translate the glyph image before rendering. Can be 0 (if no translation). The origin is expressed in 26.6 pixels. destroy A boolean that indicates that the original glyph image should be destroyed by this function. It is never destroyed in case of error. return FreeType error code. 0 means success. note This function does nothing if the glyph format isn't scalable. The glyph image is translated with the origin vector before rendering. The first parameter is a pointer to an FT_Glyph handle that will be replaced by this function (with newly allocated data). Typically, you would do something like the following (omitting error handling). FT_Glyph glyph; FT_BitmapGlyph glyph_bitmap; // load glyph error = FT_Load_Char( face, glyph_index, FT_LOAD_DEFAULT ); // extract glyph image error = FT_Get_Glyph( face->glyph, &glyph ); // convert to a bitmap (default render mode + destroying old) if ( glyph->format != FT_GLYPH_FORMAT_BITMAP ) { error = FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL, 0, 1 ); if ( error ) // `glyph' unchanged ... } // access bitmap content by typecasting glyph_bitmap = (FT_BitmapGlyph)glyph; // do funny stuff with it, like blitting/drawing ... // discard glyph image (bitmap or not) FT_Done_Glyph( glyph ); Here is another example, again without error handling.

Circular arcs are used to join two lines smoothly. FT_STROKER_LINEJOIN_BEVEL Used to render beveled line joins. The outer corner of the joined lines is filled by enclosing the triangular region of the corner with a straight line between the outer corners of each stroke. FT_STROKER_LINEJOIN_MITER_FIXED Used to render mitered line joins, with fixed bevels if the miter limit is exceeded. The outer edges of the strokes for the two segments are extended until they meet at an angle. A bevel join (see above) is used if the segments meet at too sharp an angle and the outer edges meet beyond a distance corresponding to the meter limit. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter line join as used in PostScript and PDF. FT_STROKER_LINEJOIN_MITER_VARIABLE FT_STROKER_LINEJOIN_MITER Used to render mitered line joins, with variable bevels if the miter limit is exceeded. The intersection of the strokes is clipped perpendicularly to the bisector, at a distance corresponding to the miter limit. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line join as used in XPS. FT_STROKER_LINEJOIN_MITER is an alias for FT_STROKER_LINEJOIN_MITER_VARIABLE , retained for backward compatibility.

If 1, the outline is treated as an open path instead of a closed one. return FreeType error code. 0 means success. note If opened is 0 (the default), the outline is treated as a closed path, and the stroker generates two distinct \u2018border\u2019 outlines. If opened is 1, the outline is processed as an open path, and the stroker generates a single \u2018stroke\u2019 outline. This function calls FT_Stroker_Rewind automatically.

FT_Stroker_GetBorderCounts \u00b6 Defined in FT_STROKER_H (freetype/ftstroke.h). FT_EXPORT( FT_Error ) FT_Stroker_GetBorderCounts ( FT_Stroker stroker, FT_StrokerBorder border, FT_UInt *anum_points, FT_UInt *anum_contours ); Call this function once you have finished parsing your paths with the stroker. It returns the number of points and contours necessary to export one of the \u2018border\u2019 or \u2018stroke\u2019 outlines generated by the stroker. input stroker The target stroker handle. border The border index. output anum_points The number of points. anum_contours The number of contours. return FreeType error code. 0 means success. note When an outline, or a sub-path, is \u2018closed\u2019, the stroker generates two independent \u2018border\u2019 outlines, named \u2018left\u2019 and \u2018right\u2019.

They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters. Unicode maintains two different sets, namely \u2018Standardized Variation Sequences\u2019 and registered \u2018Ideographic Variation Sequences\u2019 (IVS), collected in the \u2018Ideographic Variation Database\u2019 (IVD). https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt https://unicode.org/reports/tr37/ https://unicode.org/ivd/ To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.

A variation may be either \u2018default\u2019 or \u2018non-default\u2019 for a given font.

This is a mode where all glyphs loaded from a given FT_Face are provided by the client application. Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor. To enable this mode, you must use FT_Open_Face , passing an FT_Parameter with the FT_PARAM_TAG_INCREMENTAL tag and an FT_Incremental_Interface value. See the comments for FT_Incremental_InterfaceRec for an example. FT_Incremental \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_IncrementalRec_* FT_Incremental ; An opaque type describing a user-provided object used to implement \u2018incremental\u2019 glyph loading within FreeType. This is used to support embedded fonts in certain environments (e.g., PostScript interpreters), where the glyph data isn't in the font file, or must be overridden by different values. note It is up to client applications to create and implement FT_Incremental objects, as long as they provide implementations for the methods FT_Incremental_GetGlyphDataFunc , FT_Incremental_FreeGlyphDataFunc and FT_Incremental_GetGlyphMetricsFunc . See the description of FT_Incremental_InterfaceRec to understand how to use incremental objects with FreeType. FT_Incremental_MetricsRec \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_Incremental_MetricsRec_ { FT_Long bearing_x; FT_Long bearing_y; FT_Long advance; FT_Long advance_v; /* since 2.3.12 */ } FT_Incremental_MetricsRec ; A small structure used to contain the basic glyph metrics returned by the FT_Incremental_GetGlyphMetricsFunc method. fields bearing_x Left bearing, in font units. bearing_y Top bearing, in font units. advance Horizontal component of glyph advance, in font units. advance_v Vertical component of glyph advance, in font units. note These correspond to horizontal or vertical metrics depending on the value of the vertical argument to the function FT_Incremental_GetGlyphMetricsFunc . FT_Incremental_Metrics \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_Incremental_MetricsRec_* FT_Incremental_Metrics ; A handle to an FT_Incremental_MetricsRec structure.

Note that the format of the glyph's data bytes depends on the font file format. For TrueType, it must correspond to the raw bytes within the \u2018glyf\u2019 table. For PostScript formats, it must correspond to the unencrypted charstring bytes, without any lenIV header. It is undefined for any other format. input incremental Handle to an opaque FT_Incremental handle provided by the client application. glyph_index Index of relevant glyph. output adata A structure describing the returned glyph data bytes (which will be accessed as a read-only byte block). return FreeType error code. 0 means success. note If this function returns successfully the method FT_Incremental_FreeGlyphDataFunc will be called later to release the data bytes. Nested calls to FT_Incremental_GetGlyphDataFunc can happen for compound glyphs. FT_Incremental_FreeGlyphDataFunc \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef void (* FT_Incremental_FreeGlyphDataFunc )( FT_Incremental incremental, FT_Data * data ); A function used to release the glyph data bytes returned by a successful call to FT_Incremental_GetGlyphDataFunc . input incremental A handle to an opaque FT_Incremental handle provided by the client application. data A structure describing the glyph data bytes (which will be accessed as a read-only byte block). FT_Incremental_GetGlyphMetricsFunc \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef FT_Error (* FT_Incremental_GetGlyphMetricsFunc ) ( FT_Incremental incremental, FT_UInt glyph_index, FT_Bool vertical, FT_Incremental_MetricsRec *ametrics ); A function used to retrieve the basic metrics of a given glyph index before accessing its data. This allows for handling font types such as PCL XL Format 1, Class 2 downloaded TrueType fonts, where the glyph metrics ( hmtx and vmtx tables) are permitted to be omitted from the font, and the relevant metrics included in the header of the glyph outline data. Importantly, this is not intended to allow custom glyph metrics (for example, Postscript Metrics dictionaries), because that conflicts with the requirements of outline hinting. Such custom metrics must be handled separately, by the calling application. input incremental A handle to an opaque FT_Incremental handle provided by the client application. glyph_index Index of relevant glyph. vertical If true, return vertical metrics. ametrics This parameter is used for both input and output. The original glyph metrics, if any, in font units. If metrics are not available all the values must be set to zero. output ametrics The glyph metrics in font units.

\u00bb Core API \u00bb Glyph Layer Management Glyph Layer Management \u00b6 Synopsis \u00b6 The functions described here allow access of colored glyph layer data in OpenType's \u2018COLR\u2019 tables. FT_LayerIterator \u00b6 Defined in FT_COLOR_H (freetype/ftcolor.h). typedef struct FT_LayerIterator_ { FT_UInt num_layers; FT_UInt layer; FT_Byte * p; } FT_LayerIterator ; This iterator object is needed for FT_Get_Color_Glyph_Layer . fields num_layers The number of glyph layers for the requested glyph index. Will be set by FT_Get_Color_Glyph_Layer . layer The current layer. Will be set by FT_Get_Color_Glyph_Layer . p An opaque pointer into \u2018COLR\u2019 table data. The caller must set this to NULL before the first call of FT_Get_Color_Glyph_Layer . FT_Get_Color_Glyph_Layer \u00b6 Defined in FT_COLOR_H (freetype/ftcolor.h). FT_EXPORT( FT_Bool ) FT_Get_Color_Glyph_Layer ( FT_Face face, FT_UInt base_glyph, FT_UInt *aglyph_index, FT_UInt *acolor_index, FT_LayerIterator * iterator ); This is an interface to the \u2018COLR\u2019 table in OpenType fonts to iteratively retrieve the colored glyph layers associated with the current glyph slot. https://docs.microsoft.com/en-us/typography/opentype/spec/colr The glyph layer data for a given glyph index, if present, provides an alternative, multi-color glyph representation: Instead of rendering the outline or bitmap with the given glyph index, glyphs with the indices and colors returned by this function are rendered layer by layer. The returned elements are ordered in the z direction from bottom to top; the 'n'th element should be rendered with the associated palette color and blended on top of the already rendered layers (elements 0, 1, \u2026, n-1). input face A handle to the parent face object. base_glyph The glyph index the colored glyph layers are associated with. inout iterator An FT_LayerIterator object. For the first call you should set iterator->p to NULL . For all following calls, simply use the same object again. output aglyph_index The glyph index of the current layer. acolor_index The color index into the font face's color palette of the current layer. The value 0xFFFF is special; it doesn't reference a palette entry but indicates that the text foreground color should be used instead (to be set up by the application outside of FreeType). The color palette can be retrieved with FT_Palette_Select . return Value 1 if everything is OK. If there are no more layers (or if there are no layers at all), value 0 gets returned. In case of an error, value 0 is returned also. note This function is necessary if you want to handle glyph layers by yourself. In particular, functions that operate with FT_GlyphRec objects (like FT_Get_Glyph or FT_Glyph_To_Bitmap ) don't have access to this information. Note that FT_Render_Glyph is able to handle colored glyph layers automatically if the FT_LOAD_COLOR flag is passed to a previous call to FT_Load_Glyph . [This is an experimental feature.] example FT_Color* palette; FT_LayerIterator iterator; FT_Bool have_layers; FT_UInt layer_glyph_index; FT_UInt layer_color_index; error = FT_Palette_Select( face, palette_index, &palette ); if ( error ) palette = NULL; iterator.p = NULL; have_layers = FT_Get_Color_Glyph_Layer( face, glyph_index, &layer_glyph_index, &layer_color_index, &iterator ); if ( palette && have_layers ) { do { FT_Color layer_color; if ( layer_color_index == 0xFFFF ) layer_color = text_foreground_color; else layer_color = palette[layer_color_index]; // Load and render glyph `layer_glyph_index', then // blend resulting pixmap (using color `layer_color') // with previously created pixmaps. } while ( FT_Get_Color_Glyph_Layer( face, glyph_index, &layer_glyph_index, &layer_color_index, &iterator ) ); } since 2.10 FT_PaintFormat \u00b6 Defined in FT_COLOR_H (freetype/ftcolor.h). typedef enum FT_PaintFormat_ { FT_COLR_PAINTFORMAT_COLR_LAYERS = 1, FT_COLR_PAINTFORMAT_SOLID = 2, FT_COLR_PAINTFORMAT_LINEAR_GRADIENT = 4, FT_COLR_PAINTFORMAT_RADIAL_GRADIENT = 6, FT_COLR_PAINTFORMAT_SWEEP_GRADIENT = 8, FT_COLR_PAINTFORMAT_GLYPH = 10, FT_COLR_PAINTFORMAT_COLR_GLYPH = 11, FT_COLR_PAINTFORMAT_TRANSFORM = 12, FT_COLR_PAINTFORMAT_TRANSLATE = 14, FT_COLR_PAINTFORMAT_SCALE = 16, FT_COLR_PAINTFORMAT_ROTATE = 24, FT_COLR_PAINTFORMAT_SKEW = 28, FT_COLR_PAINTFORMAT_COMPOSITE = 32, FT_COLR_PAINT_FORMAT_MAX = 33, FT_COLR_PAINTFORMAT_UNSUPPORTED = 255 } FT_PaintFormat ; Enumeration describing the different paint format types of the v1 extensions to the \u2018COLR\u2019 table, see \u2018 https://github.com/googlefonts/colr-gradients-spec \u2019. The enumeration values loosely correspond with the format numbers of the specification: FreeType always returns a fully specified \u2018Paint\u2019 structure for the \u2018Transform\u2019, \u2018Translate\u2019, \u2018Scale\u2019, \u2018Rotate\u2019, and \u2018Skew\u2019 table types even though the specification has different formats depending on whether or not a center is specified, whether the scale is uniform in x and y direction or not, etc. Also, only non-variable format identifiers are listed in this enumeration; as soon as support for variable \u2018COLR\u2019 v1 fonts is implemented, interpolation is performed dependent on axis coordinates, which are configured on the FT_Face through FT_Set_Var_Design_Coordinates . This implies that always static, readily interpolated values are returned in the \u2018Paint\u2019 structures. since 2.13 FT_ColorStopIterator \u00b6 Defined in FT_COLOR_H (freetype/ftcolor.h). typedef struct FT_ColorStopIterator_ { FT_UInt num_color_stops; FT_UInt current_color_stop; FT_Byte * p; FT_Bool read_variable; } FT_ColorStopIterator ; This iterator object is needed for FT_Get_Colorline_Stops . It keeps state while iterating over the stops of an FT_ColorLine , representing the ColorLine struct of the v1 extensions to \u2018COLR\u2019, see \u2018 https://github.com/googlefonts/colr-gradients-spec \u2019. Do not manually modify fields of this iterator. fields num_color_stops The number of color stops for the requested glyph index. Set by FT_Get_Paint . current_color_stop The current color stop.

Compare Offset<24> there. When \u2018COLR\u2019 v1 paint tables represented by FreeType objects such as FT_PaintColrLayers , FT_PaintComposite , or FT_PaintTransform reference downstream nested paint tables, we do not immediately retrieve them but encapsulate their location in this type. Use FT_Get_Paint to retrieve the actual FT_COLR_Paint object that describes the details of the respective paint table. fields p An internal offset to a Paint table, needs to be set to NULL before passing this struct as an argument to FT_Get_Paint . insert_root_transform An internal boolean to track whether an initial root transform is to be provided.

FT_EXPORT( FT_Bool ) FT_Get_Color_Glyph_Paint ( FT_Face face, FT_UInt base_glyph, FT_Color_Root_Transform root_transform, FT_OpaquePaint * paint ); This is the starting point and interface to color gradient information in a \u2018COLR\u2019 v1 table in OpenType fonts to recursively retrieve the paint tables for the directed acyclic graph of a colored glyph, given a glyph ID. https://github.com/googlefonts/colr-gradients-spec In a \u2018COLR\u2019 v1 font, each color glyph defines a directed acyclic graph of nested paint tables, such as PaintGlyph , PaintSolid , PaintLinearGradient , PaintRadialGradient , and so on. Using this function and specifying a glyph ID, one retrieves the root paint table for this glyph ID. This function allows control whether an initial root transform is returned to configure scaling, transform, and translation correctly on the client's graphics context. The initial root transform is computed and returned according to the values configured for FT_Size and FT_Set_Transform on the FT_Face object, see below for details of the root_transform parameter. This has implications for a client \u2018COLR\u2019 v1 implementation: When this function returns an initially computed root transform, at the time of executing the FT_PaintGlyph operation, the contours should be retrieved using FT_Load_Glyph at unscaled, untransformed size. This is because the root transform applied to the graphics context will take care of correct scaling. Alternatively, to allow hinting of contours, at the time of executing FT_Load_Glyph , the current graphics context transformation matrix can be decomposed into a scaling matrix and a remainder, and FT_Load_Glyph can be used to retrieve the contours at scaled size. Care must then be taken to blit or clip to the graphics context with taking this remainder transformation into account. input face A handle to the parent face object. base_glyph The glyph index for which to retrieve the root paint table. root_transform Specifies whether an initially computed root is returned by the FT_PaintTransform operation to account for the activated size (see FT_Activate_Size ) and the configured transform and translate (see FT_Set_Transform ). This root transform is returned before nodes of the glyph graph of the font are returned. Subsequent FT_COLR_Paint structures contain unscaled and untransformed values. The inserted root transform enables the client application to apply an initial transform to its graphics context. When executing subsequent FT_COLR_Paint operations, values from FT_COLR_Paint operations will ultimately be correctly scaled because of the root transform applied to the graphics context. Use FT_COLOR_INCLUDE_ROOT_TRANSFORM to include the root transform, use FT_COLOR_NO_ROOT_TRANSFORM to not include it. The latter may be useful when traversing the \u2018COLR\u2019 v1 glyph graph and reaching a FT_PaintColrGlyph . When recursing into FT_PaintColrGlyph and painting that inline, no additional root transform is needed as it has already been applied to the graphics context at the beginning of drawing this glyph. output paint The FT_OpaquePaint object that references the actual paint table. The respective actual FT_COLR_Paint object is retrieved via FT_Get_Paint . return Value 1 if everything is OK. If no color glyph is found, or the root paint could not be retrieved, value 0 gets returned. In case of an error, value 0 is returned also. since 2.13 FT_Get_Color_Glyph_ClipBox \u00b6 Defined in FT_COLOR_H (freetype/ftcolor.h).

The clip box is computed taking scale and transformations configured on the FT_Face into account. FT_ClipBox contains FT_Vector values in 26.6 format. return Value 1 if a clip box is found.

If the root paint of a color glyph, or a nested paint of a \u2018COLR\u2019 glyph is a PaintColrLayers table, this function retrieves the layers of the PaintColrLayers table. The FT_PaintColrLayers object contains an FT_LayerIterator , which is used here to iterate over the layers. Each layer is returned as an FT_OpaquePaint object, which then can be used with FT_Get_Paint to retrieve the actual paint object. input face A handle to the parent face object. inout iterator The FT_LayerIterator from an FT_PaintColrLayers object, for which the layers are to be retrieved. The internal state of the iterator is incremented after one call to this function for retrieving one layer. output paint The FT_OpaquePaint object that references the actual paint table.

Should you define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ftoption.h file, this enables ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise. ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of 3. Using the subpixel coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed evenly. Therefore, an equalizing 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties: It should be symmetrical, like { a, b, c, b, a }, to avoid any shifts in appearance. It should be color-balanced, meaning a + b = c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally. It should be normalized, meaning 2a + 2b + c = 1.0 to maintain overall brightness. Boxy 3-tap filter {0, \u2153, \u2153, \u2153, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant. Use the FT_Library_SetLcdFilter or FT_Library_SetLcdFilterWeights API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through FT_Render_Glyph . Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel can be rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage. The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-\u2153, 0}, {0, 0}, {\u2153, 0}} for standard RGB striped panel or {{-\u2159, \u00bc}, {-\u2159, -\u00bc}, {\u2153, 0}} for a certain PenTile panel. Use the FT_Library_SetLcdGeometry API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter. As a result of ClearType filtering or Harmony shifts, the resulting dimensions of LCD bitmaps can be slightly wider or taller than the dimensions the original outline with regard to the pixel grid. For example, for FT_RENDER_MODE_LCD , the filter adds 2 subpixels to the left, and 2 subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter. The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through FT_Render_Glyph , FT_Load_Glyph , FT_Load_Char , and FT_Glyph_To_Bitmap , when FT_RENDER_MODE_LCD or FT_RENDER_MODE_LCD_V is specified. This API does not control FT_Outline_Render and FT_Outline_Get_Bitmap . The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space.

To add a new renderer, simply use FT_Add_Module . To retrieve a renderer by its name, use FT_Get_Module . FT_Set_Renderer \u00b6 Defined in FT_RENDER_H (freetype/ftrender.h). FT_EXPORT( FT_Error ) FT_Set_Renderer ( FT_Library library, FT_Renderer renderer, FT_UInt num_params, FT_Parameter * parameters ); Set the current renderer to use, and set additional mode. inout library A handle to the library object. input renderer A handle to the renderer object. num_params The number of additional parameters. parameters Additional parameters. return FreeType error code. 0 means success. note In case of success, the renderer will be used to convert glyph images in the renderer's known format into bitmaps. This doesn't change the current renderer for other formats. Currently, no FreeType renderer module uses parameters ; you should thus always pass NULL as the value. FT_Set_Debug_Hook \u00b6 Defined in FT_MODULE_H (freetype/ftmodapi.h). FT_EXPORT( void ) FT_Set_Debug_Hook ( FT_Library library, FT_UInt hook_index, FT_DebugHook_Func debug_hook ); Set a debug hook function for debugging the interpreter of a font format. While this is a public API function, an application needs access to FreeType's internal header files to do something useful. Have a look at the source code of the ttdebug FreeType demo program for an example of its usage. inout library A handle to the library object. input hook_index The index of the debug hook. You should use defined enumeration macros like FT_DEBUG_HOOK_TRUETYPE . debug_hook The function used to debug the interpreter. note Currently, four debug hook slots are available, but only one (for the TrueType interpreter) is defined. FT_Driver \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_DriverRec_* FT_Driver ; A handle to a given FreeType font driver object. A font driver is a module capable of creating faces from font files.

Its job is essentially to activate debug mode to enforce single-stepping, to call the main loop function to interpret the next opcode, and to show the changed context to the user. An example for such a main loop function is TT_RunIns (declared in FreeType's internal header file src/truetype/ttinterp.h ). Have a look at the source code of the ttdebug FreeType demo program for an example of a drop-in replacement. inout arg A typeless pointer, to be cast to the main loop function's data structure (which depends on the font module). For TrueType fonts it is bytecode interpreter's execution context, TT_ExecContext , which is declared in FreeType's internal header file tttypes.h .

If bit 0 is unset, the point is \u2018off\u2019 the curve, i.e., a Bezier control point, while it is \u2018on\u2019 if set. Bit 1 is meaningful for \u2018off\u2019 points only.

If bit 2 is set, bits 5-7 contain the drop-out mode (as defined in the OpenType specification; the value is the same as the argument to the \u2018SCANMODE\u2019 instruction). Bits 3 and 4 are reserved for internal purposes. contours An array of n_contours shorts, giving the end point of each contour within the outline. For example, the first contour is defined by the points \u20180\u2019 to contours[0] , the second one is defined by the points contours[0]+1 to contours[1] , etc. flags A set of bit flags used to characterize the outline and give hints to the scan-converter and hinter on how to convert/grid-fit it. See FT_OUTLINE_XXX . note The B/W rasterizer only checks bit 2 in the tags array for the first point of each contour. The drop-out mode as given with FT_OUTLINE_IGNORE_DROPOUTS , FT_OUTLINE_SMART_DROPOUTS , and FT_OUTLINE_INCLUDE_STUBS in flags is then overridden.

FT_EXPORT( FT_Error ) FT_Outline_New ( FT_Library library, FT_UInt numPoints, FT_Int numContours, FT_Outline *anoutline ); Create a new outline of a given size. input library A handle to the library object from where the outline is allocated. Note however that the new outline will not necessarily be freed , when destroying the library, by FT_Done_FreeType . numPoints The maximum number of points within the outline.

This value must be in the range 0 to numPoints . output anoutline A handle to the new outline. return FreeType error code. 0 means success. note The reason why this function takes a library parameter is simply to use the library's memory allocator. FT_Outline_Done \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h).

FT_Outline_Copy \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Copy ( const FT_Outline * source, FT_Outline *target ); Copy an outline into another one.

FT_Outline_Translate \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Translate ( const FT_Outline * outline, FT_Pos xOffset, FT_Pos yOffset ); Apply a simple translation to the points of an outline. inout outline A pointer to the target outline descriptor. input xOffset The horizontal offset. yOffset The vertical offset. FT_Outline_Transform \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Transform ( const FT_Outline * outline, const FT_Matrix * matrix ); Apply a simple 2x2 matrix to all of an outline's points. Useful for applying rotations, slanting, flipping, etc. inout outline A pointer to the target outline descriptor. input matrix A pointer to the transformation matrix. note You can use FT_Outline_Translate if you need to translate the outline's points. FT_Outline_Embolden \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Embolden ( FT_Outline * outline, FT_Pos strength ); Embolden an outline.

Negative strength values to reduce the outline thickness are possible also. inout outline A handle to the target outline. input strength How strong the glyph is emboldened. Expressed in 26.6 pixel format. return FreeType error code. 0 means success. note The used algorithm to increase or decrease the thickness of the glyph doesn't change the number of points; this means that certain situations like acute angles or intersections are sometimes handled incorrectly. If you need \u2018better\u2019 metrics values you should call FT_Outline_Get_CBox or FT_Outline_Get_BBox . To get meaningful results, font scaling values must be set with functions like FT_Set_Char_Size before calling FT_Render_Glyph. example FT_Load_Glyph( face, index, FT_LOAD_DEFAULT ); if ( face->glyph->format == FT_GLYPH_FORMAT_OUTLINE ) FT_Outline_Embolden( &face->glyph->outline, strength ); FT_Outline_EmboldenXY \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_EmboldenXY ( FT_Outline * outline, FT_Pos xstrength, FT_Pos ystrength ); Embolden an outline. The new outline will be xstrength pixels wider and ystrength pixels higher. Otherwise, it is similar to FT_Outline_Embolden , which uses the same strength in both directions. since 2.4.10 FT_Outline_Reverse \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Reverse ( FT_Outline * outline ); Reverse the drawing direction of an outline. This is used to ensure consistent fill conventions for mirrored glyphs. inout outline A pointer to the target outline descriptor. note This function toggles the bit flag FT_OUTLINE_REVERSE_FILL in the outline's flags field. It shouldn't be used by a normal client application, unless it knows what it is doing. FT_Outline_Check \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Check ( FT_Outline * outline ); Check the contents of an outline descriptor. input outline A handle to a source outline. return FreeType error code. 0 means success. note An empty outline, or an outline with a single point only is also valid. FT_Outline_Get_CBox \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Get_CBox ( const FT_Outline * outline, FT_BBox *acbox ); Return an outline's \u2018control box\u2019. The control box encloses all the outline's points, including Bezier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline that contains Bezier outside arcs). Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the \u2018ftbbox\u2019 component, which is dedicated to this single task. input outline A pointer to the source outline descriptor. output acbox The outline's control box. note See FT_Glyph_Get_CBox for a discussion of tricky fonts. FT_Outline_Get_BBox \u00b6 Defined in FT_BBOX_H (freetype/ftbbox.h). FT_EXPORT( FT_Error ) FT_Outline_Get_BBox ( FT_Outline * outline, FT_BBox *abbox ); Compute the exact bounding box of an outline. This is slower than computing the control box. However, it uses an advanced algorithm that returns very quickly when the two boxes coincide. Otherwise, the outline Bezier arcs are traversed to extract their extrema. input outline A pointer to the source outline. output abbox The outline's exact bounding box. return FreeType error code. 0 means success. note If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE , the resulting BBox is meaningless. To get reasonable values for the BBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the BBox, which can be eventually converted back to font units. FT_Outline_Get_Bitmap \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Get_Bitmap ( FT_Library library, FT_Outline * outline, const FT_Bitmap *abitmap ); Render an outline within a bitmap. The outline's image is simply OR-ed to the target bitmap. input library A handle to a FreeType library object. outline A pointer to the source outline descriptor. inout abitmap A pointer to the target bitmap descriptor. return FreeType error code. 0 means success. note This function does not create the bitmap, it only renders an outline image within the one you pass to it! Consequently, the various fields in abitmap should be set accordingly. It will use the raster corresponding to the default glyph format. The value of the num_grays field in abitmap is ignored. If you select the gray-level rasterizer, and you want less than 256 gray levels, you have to use FT_Outline_Render directly. FT_Outline_Render \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Render ( FT_Library library, FT_Outline * outline, FT_Raster_Params * params ); Render an outline within a bitmap using the current scan-convert. input library A handle to a FreeType library object. outline A pointer to the source outline descriptor. inout params A pointer to an FT_Raster_Params structure used to describe the rendering operation. return FreeType error code. 0 means success. note This advanced function uses FT_Raster_Params as an argument. The field params.source will be set to outline before the scan converter is called, which means that the value you give to it is actually ignored. Either params.target must point to preallocated bitmap, or FT_RASTER_FLAG_DIRECT must be set in params.flags allowing FreeType rasterizer to be used for direct composition, translucency, etc. See FT_Raster_Params for more details. FT_Outline_Decompose \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Decompose ( FT_Outline * outline, const FT_Outline_Funcs * func_interface, void * user ); Walk over an outline's structure to decompose it into individual segments and Bezier arcs. This function also emits \u2018move to\u2019 operations to indicate the start of new contours in the outline. input outline A pointer to the source target. func_interface A table of \u2018emitters\u2019, i.e., function pointers called during decomposition to indicate path operations. inout user A typeless pointer that is passed to each emitter during the decomposition. It can be used to store the state during the decomposition. return FreeType error code. 0 means success. note Degenerate contours, segments, and Bezier arcs may be reported. In most cases, it is best to filter these out before using the outline for stroking or other path modification purposes (which may cause degenerate segments to become non-degenrate and visible, like when stroke caps are used or the path is otherwise outset). Some glyph outlines may contain deliberate degenerate single points for mark attachement. Similarly, the function returns success for an empty outline also (doing nothing, this is, not calling any emitter); if necessary, you should filter this out, too.

The TrueType and PostScript specifications use different conventions to determine whether outline contours should be filled or unfilled. values FT_ORIENTATION_TRUETYPE According to the TrueType specification, clockwise contours must be filled, and counter-clockwise ones must be unfilled. FT_ORIENTATION_POSTSCRIPT According to the PostScript specification, counter-clockwise contours must be filled, and clockwise ones must be unfilled. FT_ORIENTATION_FILL_RIGHT This is identical to FT_ORIENTATION_TRUETYPE , but is used to remember that in TrueType, everything that is to the right of the drawing direction of a contour must be filled. FT_ORIENTATION_FILL_LEFT This is identical to FT_ORIENTATION_POSTSCRIPT , but is used to remember that in PostScript, everything that is to the left of the drawing direction of a contour must be filled. FT_ORIENTATION_NONE The orientation cannot be determined. That is, different parts of the glyph have different orientation. FT_Outline_Get_Orientation \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Orientation ) FT_Outline_Get_Orientation ( FT_Outline * outline ); This function analyzes a glyph outline and tries to compute its fill orientation (see FT_Orientation ). This is done by integrating the total area covered by the outline. The positive integral corresponds to the clockwise orientation and FT_ORIENTATION_POSTSCRIPT is returned. The negative integral corresponds to the counter-clockwise orientation and FT_ORIENTATION_TRUETYPE is returned.

FT_OUTLINE_OWNER If set, this flag indicates that the outline's field arrays (i.e., points , flags , and contours ) are \u2018owned\u2019 by the outline object, and should thus be freed when it is destroyed. FT_OUTLINE_EVEN_ODD_FILL By default, outlines are filled using the non-zero winding rule. If set to 1, the outline will be filled using the even-odd fill rule (only works with the smooth rasterizer). FT_OUTLINE_REVERSE_FILL By default, outside contours of an outline are oriented in clock-wise direction, as defined in the TrueType specification. This flag is set if the outline uses the opposite direction (typically for Type 1 fonts). This flag is ignored by the scan converter. FT_OUTLINE_IGNORE_DROPOUTS By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information. FT_OUTLINE_SMART_DROPOUTS Select smart dropout control. If unset, use simple dropout control. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information. FT_OUTLINE_INCLUDE_STUBS If set, turn pixels on for \u2018stubs\u2019, otherwise exclude them. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information. FT_OUTLINE_OVERLAP [Since 2.10.3] This flag indicates that this outline contains overlapping contours and the anti-aliased renderer should perform oversampling to mitigate possible artifacts. This flag should not be set for well designed glyphs without overlaps because it quadruples the rendering time. FT_OUTLINE_HIGH_PRECISION This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter. FT_OUTLINE_SINGLE_PASS This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image. Normally, it is set for very large character sizes. It is only a hint that might be completely ignored by a given scan-converter. note The flags FT_OUTLINE_IGNORE_DROPOUTS , FT_OUTLINE_SMART_DROPOUTS , and FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer. There exists a second mechanism to pass the drop-out mode to the B/W rasterizer; see the tags field in FT_Outline .

This section documents the available properties, together with auxiliary macros and structures.

FT_HINTING_ADOBE Use the hinting engine contributed by Adobe. since 2.9 hinting-engine \u00b6 Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between \u2018freetype\u2019 and \u2018adobe\u2019 if compiled with CFF_CONFIG_OPTION_OLD_ENGINE . If this configuration macro isn't defined, \u2018hinting-engine\u2019 does nothing. The same holds for the Type 1 and CID modules if compiled with T1_CONFIG_OPTION_OLD_ENGINE . For the \u2018cff\u2019 module, the default engine is \u2018adobe\u2019. For both the \u2018type1\u2019 and \u2018t1cid\u2019 modules, the default engine is \u2018adobe\u2019, too. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values \u2018adobe\u2019 or \u2018freetype\u2019). example The following example code demonstrates how to select Adobe's hinting engine for the \u2018cff\u2019 module (omitting the error handling). FT_Library library; FT_UInt hinting_engine = FT_HINTING_ADOBE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"cff\", \"hinting-engine\", &hinting_engine ); since 2.4.12 (for \u2018cff\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) no-stem-darkening \u00b6 All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type 1, and CID font modules if the \u2018Adobe\u2019 engine is selected (which is the default). Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see FT_Render_Glyph . When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy! Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs \u2018thin out\u2019. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore \u2018blacker\u2019. This counteracts the \u2018thinning out\u2019 of glyphs, making text remain readable at smaller sizes. For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, no-stem-darkening is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver. Note that stem darkening is never applied if FT_LOAD_NO_SCALE is set. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values 1 and 0 for \u2018on\u2019 and \u2018off\u2019, respectively). It can also be set per face using FT_Face_Properties with FT_PARAM_TAG_STEM_DARKENING . example FT_Library library; FT_Bool no_stem_darkening = TRUE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"cff\", \"no-stem-darkening\", &no_stem_darkening ); since 2.4.12 (for \u2018cff\u2019 module) 2.6.2 (for \u2018autofitter\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) darkening-parameters \u00b6 By default, the Adobe hinting engine, as used by the CFF, Type 1, and CID font drivers, darkens stems as follows (if the no-stem-darkening property isn't set): stem width <= 0.5px: darkening amount = 0.4px stem width = 1px: darkening amount = 0.275px stem width = 1.667px: darkening amount = 0.275px stem width >= 2.333px: darkening amount = 0px and piecewise linear in-between. At configuration time, these four control points can be set with the macro CFF_CONFIG_OPTION_DARKENING_PARAMETERS ; the CFF, Type 1, and CID drivers share these values. At runtime, the control points can be changed using the darkening-parameters property (see the example below that demonstrates this for the Type 1 driver). The x values give the stem width, and the y values the darkening amount. The unit is 1000 th of pixels. All coordinate values must be positive; the x values must be monotonically increasing; the y values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4). The auto-hinter provides this property, too, as an experimental feature. See no-stem-darkening for more. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable, using eight comma-separated integers without spaces. Here the above example, using \\ to break the line for readability. FREETYPE_PROPERTIES=\\ type1:darkening-parameters=500,300,1000,200,1500,100,2000,0 example FT_Library library; FT_Int darken_params[8] = { 500, 300, // x1, y1 1000, 200, // x2, y2 1500, 100, // x3, y3 2000, 0 }; // x4, y4 FT_Init_FreeType( &library ); FT_Property_Set( library, \"type1\", \"darkening-parameters\", darken_params ); since 2.5.1 (for \u2018cff\u2019 module) 2.6.2 (for \u2018autofitter\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) random-seed \u00b6 By default, the seed value for the CFF \u2018random\u2019 operator and the similar \u20180 28 callothersubr pop\u2019 command for the Type 1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by \u2018random\u2019 are repeatable. The random-seed property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the intitialRandomSeed private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of initialRandomSeed , which is consequently ignored. note This property can be set via the FREETYPE_PROPERTIES environment variable. It can also be set per face using FT_Face_Properties with FT_PARAM_TAG_RANDOM_SEED . since 2.8 (for \u2018cff\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) no-long-family-names \u00b6 If PCF_CONFIG_OPTION_LONG_FAMILY_NAMES is active while compiling FreeType, the PCF driver constructs long family names. There are many PCF fonts just called \u2018Fixed\u2019 which look completely different, and which have nothing to do with each other. When selecting \u2018Fixed\u2019 in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name. It also checks whether there are \u2018wide\u2019 characters; all put together, family names like \u2018Sony Fixed\u2019 or \u2018Misc Fixed Wide\u2019 are constructed. If no-long-family-names is set, this feature gets switched off. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values 1 and 0 for \u2018on\u2019 and \u2018off\u2019, respectively). example FT_Library library; FT_Bool no_long_family_names = TRUE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"pcf\", \"no-long-family-names\", &no_long_family_names ); since 2.8 TT_INTERPRETER_VERSION_XXX \u00b6 Defined in FT_DRIVER_H (freetype/ftdriver.h). # define TT_INTERPRETER_VERSION_35 35 # define TT_INTERPRETER_VERSION_38 38 # define TT_INTERPRETER_VERSION_40 40 A list of constants used for the interpreter-version property to select the hinting engine for Truetype fonts. The numeric value in the constant names represents the version number as returned by the \u2018GETINFO\u2019 bytecode instruction. values TT_INTERPRETER_VERSION_35 Version 35 corresponds to MS rasterizer v.1.7 as used e.g. in Windows 98; only grayscale and B/W rasterizing is supported. TT_INTERPRETER_VERSION_38 Version 38 corresponds to MS rasterizer v.1.9; it is roughly equivalent to the hinting provided by DirectWrite ClearType (as can be found, for example, in the Internet Explorer 9 running on Windows 7). It is used in FreeType to select the \u2018Infinality\u2019 subpixel hinting code. The code may be removed in a future version. TT_INTERPRETER_VERSION_40 Version 40 corresponds to MS rasterizer v.2.1; it is roughly equivalent to the hinting provided by DirectWrite ClearType (as can be found, for example, in Microsoft's Edge Browser on Windows 10). It is used in FreeType to select the \u2018minimal\u2019 subpixel hinting code, a stripped-down and higher performance version of the \u2018Infinality\u2019 code. note This property controls the behaviour of the bytecode interpreter and thus how outlines get hinted. It does not control how glyph get rasterized! In particular, it does not control subpixel color filtering. If FreeType has not been compiled with the configuration option TT_CONFIG_OPTION_SUBPIXEL_HINTING , selecting version 38 or 40 causes an FT_Err_Unimplemented_Feature error. Depending on the graphics framework, Microsoft uses different bytecode and rendering engines. As a consequence, the version numbers returned by a call to the \u2018GETINFO\u2019 bytecode instruction are more convoluted than desired. Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it. GETINFO framework version feature ------------------------------------------------------------------- 3 GDI (Win 3.1), v1.0 16-bit, first version TrueImage 33 GDI (Win NT 3.1), v1.5 32-bit HP Laserjet 34 GDI (Win 95) v1.6 font smoothing, new SCANTYPE opcode 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET bits in composite glyphs 36 MGDI (Win CE 2) v1.6+ classic ClearType 37 GDI (XP and later), v1.8 ClearType GDI+ old (before Vista) 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType, WPF Y-direction ClearType, additional error checking 39 DWrite (before Win 8) v2.0 subpixel ClearType flags in GETINFO opcode, bug fixes 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag DWrite (Win 8) in GETINFO opcode, Gray ClearType The \u2018version\u2019 field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support. version sampling rendering comment x y x y -------------------------------------------------------------- v1.0 normal normal B/W B/W bi-level v1.6 high high gray gray grayscale v1.8 high normal color-filter B/W (GDI) ClearType v1.9 high high color-filter gray Color ClearType v2.1 high normal gray B/W Gray ClearType v2.1 high high gray gray Gray ClearType Color and Gray ClearType are the two available variants of \u2018Y-direction ClearType\u2019, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is \u2018symmetric smoothing\u2019. \u2018Classic ClearType\u2019 is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is \u2018font smoothing\u2019, and \u2018Color ClearType\u2019 is sometimes also called \u2018DWrite ClearType\u2019. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called \u2018GDI ClearType\u2019. \u2018Normal\u2019 and \u2018high\u2019 sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. \u2018Normal\u2019 means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, \u2018high\u2019 means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like \u2018MIRP\u2019. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated. Note that \u2018Gray ClearType\u2019 is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1). Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals. interpreter-version \u00b6 Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old \u2018Infinality\u2019 code and new stripped-down and higher performance \u2018minimal\u2019 code) and one without, respectively. The default is subpixel support if TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support otherwise (since it isn't available then). If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if \u2018native ClearType\u2019 is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter. Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at \u2018 https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx \u2019. Note that FreeType currently doesn't really \u2018subpixel hint\u2019 (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values \u201835\u2019, \u201838\u2019, or \u201840\u2019). example The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling). FT_Library library; FT_Face face; FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35; FT_Init_FreeType( &library ); FT_Property_Set( library, \"truetype\", \"interpreter-version\", &interpreter_version ); since 2.5 svg-hooks \u00b6 Set up the interface between FreeType and an extern SVG rendering library like \u2018librsvg\u2019. All details on the function hooks can be found in section \u2018 OpenType SVG Fonts \u2019. example The following example code expects that the four hook functions svg_* are defined elsewhere. Error handling is omitted, too. FT_Library library; SVG_RendererHooks hooks = { (SVG_Lib_Init_Func)svg_init, (SVG_Lib_Free_Func)svg_free, (SVG_Lib_Render_Func)svg_render, (SVG_Lib_Preset_Slot_Func)svg_preset_slot }; FT_Init_FreeType( &library ); FT_Property_Set( library, \"ot-svg\", \"svg-hooks\", &hooks ); since 2.12 glyph-to-script-map \u00b6 Experimental only The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below. OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called \u2018features\u2019. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType. The mapping between glyph indices and scripts (in the auto-hinter sense, see the FT_AUTOHINTER_SCRIPT_XXX values) is stored as an array with num_glyphs elements, as found in the font's FT_Face structure. The glyph-to-script-map property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping. example The following example code demonstrates how to access it (omitting the error handling). FT_Library library; FT_Face face; FT_Prop_GlyphToScriptMap prop; FT_Init_FreeType( &library ); FT_New_Face( library, \"foo.ttf\", 0, &face ); prop.face = face; FT_Property_Get( library, \"autofitter\", \"glyph-to-script-map\", &prop ); // adjust `prop.map' as needed right here FT_Load_Glyph( face, ..., FT_LOAD_FORCE_AUTOHINT ); since 2.4.11 FT_AUTOHINTER_SCRIPT_XXX \u00b6 Defined in FT_DRIVER_H (freetype/ftdriver.h). # define FT_AUTOHINTER_SCRIPT_NONE 0 # define FT_AUTOHINTER_SCRIPT_LATIN 1 # define FT_AUTOHINTER_SCRIPT_CJK 2 # define FT_AUTOHINTER_SCRIPT_INDIC 3 Experimental only A list of constants used for the glyph-to-script-map property to specify the script submodule the auto-hinter should use for hinting a particular glyph. values FT_AUTOHINTER_SCRIPT_NONE Don't auto-hint this glyph. FT_AUTOHINTER_SCRIPT_LATIN Apply the latin auto-hinter.

The same is true for the CFF, Type 1, and CID font modules if the \u2018Adobe\u2019 engine is selected (which is the default). Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see FT_Render_Glyph . When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy! Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs \u2018thin out\u2019. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore \u2018blacker\u2019. This counteracts the \u2018thinning out\u2019 of glyphs, making text remain readable at smaller sizes. For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, no-stem-darkening is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones.

FT_Raster_Params \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Raster_Params_ { const FT_Bitmap * target; const void * source; int flags; FT_SpanFunc gray_spans; FT_SpanFunc black_spans; /* unused */ FT_Raster_BitTest_Func bit_test; /* unused */ FT_Raster_BitSet_Func bit_set; /* unused */ void * user; FT_BBox clip_box; } FT_Raster_Params ; A structure to hold the parameters used by a raster's render function, passed as an argument to FT_Outline_Render . fields target The target bitmap. source A pointer to the source glyph image (e.g., an FT_Outline ). flags The rendering flags. gray_spans The gray span drawing callback. black_spans Unused. bit_test Unused. bit_set Unused. user User-supplied data that is passed to each drawing callback. clip_box An optional span clipping box expressed in integer pixels (not in 26.6 fixed-point units). note The FT_RASTER_FLAG_AA bit flag must be set in the flags to generate an anti-aliased glyph bitmap, otherwise a monochrome bitmap is generated. The target should have appropriate pixel mode and its dimensions define the clipping region. If both FT_RASTER_FLAG_AA and FT_RASTER_FLAG_DIRECT bit flags are set in flags , the raster calls an FT_SpanFunc callback gray_spans with user data as an argument ignoring target . This allows direct composition over a pre-existing user surface to perform the span drawing and composition. To optionally clip the spans, set the FT_RASTER_FLAG_CLIP flag and clip_box . The monochrome raster does not support the direct mode. The gray-level rasterizer always uses 256 gray levels. If you want fewer gray levels, you have to use FT_RASTER_FLAG_DIRECT and reduce the levels in the callback function.

FT_RASTER_FLAG_AA This flag is set to indicate that an anti-aliased glyph image should be generated. Otherwise, it will be monochrome (1-bit). FT_RASTER_FLAG_DIRECT This flag is set to indicate direct rendering. In this mode, client applications must provide their own span callback. This lets them directly draw or compose over an existing bitmap. If this bit is not set, the target pixmap's buffer must be zeroed before rendering and the output will be clipped to its size. Direct rendering is only possible with anti-aliased glyphs. FT_RASTER_FLAG_CLIP This flag is only used in direct rendering mode. If set, the output will be clipped to a box specified in the clip_box field of the FT_Raster_Params structure. Otherwise, the clip_box is effectively set to the bounding box and all spans are generated. FT_RASTER_FLAG_SDF This flag is set to indicate that a signed distance field glyph image should be generated. This is only used while rendering with the FT_RENDER_MODE_SDF render mode. FT_Raster \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_RasterRec_* FT_Raster ; An opaque handle (pointer) to a raster object. Each object can be used independently to convert an outline into a bitmap or pixmap. note In FreeType 2, all rasters are now encapsulated within specific FT_Renderer modules and only used in their context.

In practice, it is an FT_Memory object, i.e., a handle to the standard FreeType memory allocator. However, this field can be completely ignored by a given raster implementation.

This function is called after a new raster object is created. input raster A handle to the new raster object. pool_base Previously, the address in memory of the render pool. Set this to NULL . pool_size Previously, the size in bytes of the render pool. Set this to 0. note Rasterizers should rely on dynamic or stack allocation if they want to (a handle to the memory allocator is passed to the rasterizer constructor).

It can be an FT_Outline or anything else in order to support a large array of glyph formats. Note also that the render function can fail and return a FT_Err_Unimplemented_Feature error code if the raster used does not support direct composition. FT_Raster_Funcs \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Raster_Funcs_ { FT_Glyph_Format glyph_format; FT_Raster_NewFunc raster_new; FT_Raster_ResetFunc raster_reset; FT_Raster_SetModeFunc raster_set_mode; FT_Raster_RenderFunc raster_render; FT_Raster_DoneFunc raster_done; } FT_Raster_Funcs ; A structure used to describe a given raster class to the library. fields glyph_format The supported glyph format for this raster. raster_new The raster constructor. raster_reset Used to reset the render pool within the raster. raster_render A function to render a glyph into a given bitmap. raster_done The raster destructor.

Instead of working with complete coverage bitmaps, it is also possible to intercept consecutive pixel runs on the same scanline with the same coverage, called spans , and process them individually. Only the smooth rasterizer permits this when calling FT_Outline_Render with FT_Raster_Params as described below. Working with either complete bitmaps or spans it is important to think of them as colorless coverage objects suitable as alpha channels to blend arbitrary colors with a background.

This callback hook is called right after the preset hook SVG_Lib_Preset_Slot_Func has been called with cache set to TRUE . The data necessary to render is available through the handle FT_SVG_Document , which is set in the other field of FT_GlyphSlotRec . The render hook is expected to render the SVG glyph to the bitmap buffer that is allocated already at slot->bitmap.buffer . It also sets the num_grays value as well as slot->format . input slot The slot to render. inout data_pointer The SVG rendering module stores a pointer variable that can be used by clients to store any data that needs to be shared across different hooks. data_pointer is essentially a pointer to that pointer such that it can be written to as well as read from. return FreeType error code. 0 means success. since 2.12 SVG_Lib_Preset_Slot_Func \u00b6 Defined in FT_OTSVG_H (freetype/otsvg.h). typedef FT_Error (* SVG_Lib_Preset_Slot_Func )( FT_GlyphSlot slot, FT_Bool cache, FT_Pointer *state ); A callback that is called to preset the glyph slot. It is called from two places. When FT_Load_Glyph needs to preset the glyph slot. Right before the svg module calls the render callback hook. When it is the former, the argument cache is set to FALSE . When it is the latter, the argument cache is set to TRUE . This distinction has been made because many calculations that are necessary for presetting a glyph slot are the same needed later for the render callback hook. Thus, if cache is TRUE , the hook can cache those calculations in a memory block referenced by the state pointer. This hook is expected to preset the slot by setting parameters such as bitmap_left , bitmap_top , width , rows , pitch , and pixel_mode . It is also expected to set all the metrics for the slot including the vertical advance if it is not already set. Typically, fonts have horizontal advances but not vertical ones. If those are available, they had already been set, otherwise they have to be estimated and set manually. The hook must take into account the transformations that have been set, and translate the transformation matrices into the SVG coordinate system, as the original matrix is intended for the TTF/CFF coordinate system. input slot The glyph slot that has the SVG document loaded. cache See description. inout data_pointer The SVG rendering module stores a pointer variable that can be used by clients to store any data that needs to be shared across different hooks. data_pointer is essentially a pointer to that pointer such that it can be written to as well as read from. return FreeType error code. 0 means success. since 2.12 SVG_RendererHooks \u00b6 Defined in FT_OTSVG_H (freetype/otsvg.h). typedef struct SVG_RendererHooks_ { SVG_Lib_Init_Func init_svg; SVG_Lib_Free_Func free_svg; SVG_Lib_Render_Func render_svg; SVG_Lib_Preset_Slot_Func preset_slot; } SVG_RendererHooks ; A structure that stores the four hooks needed to render OT-SVG glyphs properly. The structure is publicly used to set the hooks via the svg-hooks driver property. The behavior of each hook is described in its documentation. One thing to note is that the preset hook and the render hook often need to do the same operations; therefore, it's better to cache the intermediate data in a state structure to avoid calculating it twice. For example, in the preset hook one can draw the glyph on a recorder surface and later create a bitmap surface from it in the render hook. All four hooks must be non-NULL. fields init_svg The initialization hook. free_svg The cleanup hook. render_hook The render hook. preset_slot The preset hook. since 2.12 FT_SVG_DocumentRec \u00b6 Defined in FT_OTSVG_H (freetype/otsvg.h). typedef struct FT_SVG_DocumentRec_ { FT_Byte * svg_document; FT_ULong svg_document_length; FT_Size_Metrics metrics; FT_UShort units_per_EM; FT_UShort start_glyph_id; FT_UShort end_glyph_id; FT_Matrix transform; FT_Vector delta; } FT_SVG_DocumentRec ; A structure that models one SVG document. fields svg_document A pointer to the SVG document. svg_document_length The length of svg_document . metrics A metrics object storing the size information. units_per_EM The size of the EM square. start_glyph_id The first glyph ID in the glyph range covered by this document. end_glyph_id The last glyph ID in the glyph range covered by this document. transform A 2x2 transformation matrix to apply to the glyph while rendering it. delta The translation to apply to the glyph while rendering. note When an FT_GlyphSlot object slot is passed down to a renderer, the renderer can only access the metrics and units_per_EM fields via slot->face . However, when FT_Glyph_To_Bitmap sets up a dummy object, it has no way to set a face object. Thus, metrics information and units_per_EM (which is necessary for OT-SVG) has to be stored separately. since 2.12 FT_SVG_Document \u00b6 Defined in FT_OTSVG_H (freetype/otsvg.h). typedef struct FT_SVG_DocumentRec_* FT_SVG_Document ; FT_END_HEADER # endif /* OTSVG_H_ */ /* END */ A handle to an FT_SVG_DocumentRec object. since 2.12","title":"OpenType SVG Fonts"},{"location":"ft2-svg_fonts.html#opentype-svg-fonts","text":"","title":"OpenType SVG Fonts"},{"location":"ft2-svg_fonts.html#synopsis","text":"This section describes the four hooks necessary to render SVG \u2018documents\u2019 that are contained in an OpenType font's \u2018SVG \u2019 table.

FT_EXPORT( void * ) FT_Get_Sfnt_Table ( FT_Face face, FT_Sfnt_Tag tag ); Return a pointer to a given SFNT table stored within a face. input face A handle to the source. tag The index of the SFNT table. return A type-less pointer to the table. This will be NULL in case of error, or if the corresponding table was not found OR loaded from the file. Use a typecast according to tag to access the structure elements. note The table is owned by the face object and disappears with it. This function is only useful to access SFNT tables that are loaded by the sfnt, truetype, and opentype drivers. See FT_Sfnt_Tag for a list. example Here is an example demonstrating access to the \u2018vhea\u2019 table. TT_VertHeader* vert_header; vert_header = (TT_VertHeader*)FT_Get_Sfnt_Table( face, FT_SFNT_VHEA ); FT_Load_Sfnt_Table \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Error ) FT_Load_Sfnt_Table ( FT_Face face, FT_ULong tag, FT_Long offset, FT_Byte * buffer, FT_ULong * length ); Load any SFNT font table into client memory. input face A handle to the source face. tag The four-byte tag of the table to load. Use value 0 if you want to access the whole font file. Otherwise, you can use one of the definitions found in the FT_TRUETYPE_TAGS_H file, or forge a new one with FT_MAKE_TAG . offset The starting offset in the table (or file if tag == 0). output buffer The target buffer address. The client must ensure that the memory array is big enough to hold the data. inout length If the length parameter is NULL , try to load the whole table. Return an error code if it fails. Else, if *length is 0, exit immediately while returning the table's (or file) full size in it. Else the number of bytes to read from the table or file, from the starting offset. return FreeType error code. 0 means success. note If you need to determine the table's length you should first call this function with *length set to 0, as in the following example: FT_ULong length = 0; error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length ); if ( error ) { ... table does not exist ... } buffer = malloc( length ); if ( buffer == NULL ) { ... not enough memory ... } error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length ); if ( error ) { ... could not load table ... } Note that structures like TT_Header or TT_OS2 can't be used with this function; they are limited to FT_Get_Sfnt_Table . Reason is that those structures depend on the processor architecture, with varying size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian). FT_Sfnt_Table_Info \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Error ) FT_Sfnt_Table_Info ( FT_Face face, FT_UInt table_index, FT_ULong *tag, FT_ULong *length ); Return information on an SFNT table. input face A handle to the source face. table_index The index of an SFNT table. The function returns FT_Err_Table_Missing for an invalid value. inout tag The name tag of the SFNT table. If the value is NULL , table_index is ignored, and length returns the number of SFNT tables in the font. output length The length of the SFNT table (or the number of SFNT tables, depending on tag ). return FreeType error code. 0 means success. note While parsing fonts, FreeType handles SFNT tables with length zero as missing. FT_Get_CMap_Language_ID \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_ULong ) FT_Get_CMap_Language_ID ( FT_CharMap charmap ); Return cmap language ID as specified in the OpenType standard. Definitions of language ID values are in file FT_TRUETYPE_IDS_H . input charmap The target charmap. return The language ID of charmap . If charmap doesn't belong to an SFNT face, just return 0 as the default value. For a format 14 cmap (to access Unicode IVS), the return value is 0xFFFFFFFF. FT_Get_CMap_Format \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Long ) FT_Get_CMap_Format ( FT_CharMap charmap ); Return the format of an SFNT \u2018cmap\u2019 table. input charmap The target charmap. return The format of charmap .

The TrueType driver's module name is \u2018truetype\u2019; a single property interpreter-version is available, as documented in the \u2018 Driver properties \u2019 section. To help understand the differences between interpreter versions, we introduce a list of definitions, kindly provided by Greg Hitchcock. Bi-Level Rendering Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, \u2018hdmx\u2019 and \u2018LTSH\u2019, to cache hinting widths across multiple sizes and device aspect ratios. Font Smoothing Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering. ClearType Rendering Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls \u2018natural widths\u2019 ClearType, see http://rastertragedy.com/RTRCh4.htm#Sec21 . Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode. ClearType Compatible Widths One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see http://rastertragedy.com/RTRCh4.htm#Sec20 . Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths. ClearType Subpixel Positioning One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this \u2018natural mode\u2019, not to be confused with GDI's \u2018natural widths\u2019. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see http://rastertragedy.com/RTRCh4.htm#Sec22 . Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes. ClearType Backward Compatibility This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see http://rastertragedy.com/RTRCh4.htm#Sec1 and https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx .

FT_EXPORT( FT_Int ) FT_Has_PS_Glyph_Names ( FT_Face face ); Return true if a given face provides reliable PostScript glyph names. This is similar to using the FT_HAS_GLYPH_NAMES macro, except that certain fonts (mostly TrueType) contain incorrect glyph name tables. When this function returns true, the caller is sure that the glyph names returned by FT_Get_Glyph_Name are reliable. input face face handle return Boolean. True if glyph names are reliable.

Missing entries in the font's FontInfo dictionary are represented by NULL pointers. The following font formats support this feature: \u2018Type 1\u2019, \u2018Type 42\u2019, \u2018CFF\u2019, \u2018CID Type 1\u2019.

FT_Get_PS_Font_Value \u00b6 Defined in FT_TYPE1_TABLES_H (freetype/t1tables.h). FT_EXPORT( FT_Long ) FT_Get_PS_Font_Value ( FT_Face face, PS_Dict_Keys key, FT_UInt idx, void *value, FT_Long value_len ); Retrieve the value for the supplied key from a PostScript font. input face PostScript face handle. key An enumeration value representing the dictionary key to retrieve. idx For array values, this specifies the index to be returned. value A pointer to memory into which to write the value. valen_len The size, in bytes, of the memory supplied for the value. output value The value matching the above key, if it exists. return The amount of memory (in bytes) required to hold the requested value (if it exists, -1 otherwise). note The values returned are not pointers into the internal structures of the face, but are \u2018fresh\u2019 copies, so that the memory containing them belongs to the calling application. This also enforces the \u2018read-only\u2019 nature of these values, i.e., this function cannot be used to manipulate the face. value is a void pointer because the values returned can be of various types. If either value is NULL or value_len is too small, just the required memory size for the requested entry is returned. The idx parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values. PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale). IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either. If the font's format is not PostScript-based, this function returns the FT_Err_Invalid_Argument error code. since 2.4.8 T1_Blend_Flags \u00b6 Defined in FT_TYPE1_TABLES_H (freetype/t1tables.h). typedef enum T1_Blend_Flags_ { /* required fields in a FontInfo blend dictionary */ T1_BLEND_UNDERLINE_POSITION = 0, T1_BLEND_UNDERLINE_THICKNESS , T1_BLEND_ITALIC_ANGLE , /* required fields in a Private blend dictionary */ T1_BLEND_BLUE_VALUES , T1_BLEND_OTHER_BLUES , T1_BLEND_STANDARD_WIDTH , T1_BLEND_STANDARD_HEIGHT , T1_BLEND_STEM_SNAP_WIDTHS , T1_BLEND_STEM_SNAP_HEIGHTS , T1_BLEND_BLUE_SCALE , T1_BLEND_BLUE_SHIFT , T1_BLEND_FAMILY_BLUES , T1_BLEND_FAMILY_OTHER_BLUES , T1_BLEND_FORCE_BOLD , T1_BLEND_MAX /* do not remove */ } T1_Blend_Flags ; /* these constants are deprecated; use the corresponding */ /* ` T1_Blend_Flags ` values instead */ # define t1_blend_underline_position T1_BLEND_UNDERLINE_POSITION # define t1_blend_underline_thickness T1_BLEND_UNDERLINE_THICKNESS # define t1_blend_italic_angle T1_BLEND_ITALIC_ANGLE # define t1_blend_blue_values T1_BLEND_BLUE_VALUES # define t1_blend_other_blues T1_BLEND_OTHER_BLUES # define t1_blend_standard_widths T1_BLEND_STANDARD_WIDTH # define t1_blend_standard_height T1_BLEND_STANDARD_HEIGHT # define t1_blend_stem_snap_widths T1_BLEND_STEM_SNAP_WIDTHS # define t1_blend_stem_snap_heights T1_BLEND_STEM_SNAP_HEIGHTS # define t1_blend_blue_scale T1_BLEND_BLUE_SCALE # define t1_blend_blue_shift T1_BLEND_BLUE_SHIFT # define t1_blend_family_blues T1_BLEND_FAMILY_BLUES # define t1_blend_family_other_blues T1_BLEND_FAMILY_OTHER_BLUES # define t1_blend_force_bold T1_BLEND_FORCE_BOLD # define t1_blend_max T1_BLEND_MAX A set of flags used to indicate which fields are present in a given blend dictionary (font info or private).

FT_Error \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef int FT_Error ; The FreeType error code type. A value of 0 is always interpreted as a successful operation. FT_Fixed \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef signed long FT_Fixed ; This type is used to store 16.16 fixed-point values, like scaling values or matrix coefficients.

In PostScript, those values are often called (llx,lly) and (urx,ury), respectively. If yMin is negative, this value gives the glyph's descender. Otherwise, the glyph doesn't descend below the baseline. Similarly, if ymax is positive, this value gives the glyph's ascender. xMin gives the horizontal distance from the glyph's origin to the left edge of the glyph's bounding box. If xMin is negative, the glyph extends to the left of the origin. FT_Matrix \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Matrix_ { FT_Fixed xx, xy; FT_Fixed yx, yy; } FT_Matrix ; A simple structure used to store a 2x2 matrix.

FT_Data \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Data_ { const FT_Byte * pointer; FT_UInt length; } FT_Data ; Read-only binary data represented as a pointer and a length. fields pointer The data. length The length of the data in bytes. FT_MAKE_TAG \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). # define FT_MAKE_TAG ( _x1, _x2, _x3, _x4 ) \\ ( ( FT_STATIC_BYTE_CAST( FT_Tag , _x1 ) << 24 ) | \\ ( FT_STATIC_BYTE_CAST( FT_Tag , _x2 ) << 16 ) | \\ ( FT_STATIC_BYTE_CAST( FT_Tag , _x3 ) << 8 ) | \\ FT_STATIC_BYTE_CAST( FT_Tag , _x4 ) ) This macro converts four-letter tags that are used to label TrueType tables into an FT_Tag type, to be used within FreeType. note The produced values must be 32-bit integers. Don't redefine this macro. FT_Generic \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef struct FT_Generic_ { void * data; FT_Generic_Finalizer finalizer; } FT_Generic ; Client applications often need to associate their own data to a variety of FreeType core objects. For example, a text layout API might want to associate a glyph cache to a given size object. Some FreeType object contains a generic field, of type FT_Generic , which usage is left to client applications and font servers. It can be used to store a pointer to client-specific data, as well as the address of a \u2018finalizer\u2019 function, which will be called by FreeType when the object is destroyed (for example, the previous client example would put the address of the glyph cache destructor in the finalizer field). fields data A typeless pointer to any client-specified data. This field is completely ignored by the FreeType library. finalizer A pointer to a \u2018generic finalizer\u2019 function, which will be called when the object is destroyed. If this field is set to NULL , no code will be called. FT_Generic_Finalizer \u00b6 Defined in FT_TYPES_H (freetype/fttypes.h). typedef void (* FT_Generic_Finalizer )( void * object ); Describe a function used to destroy the \u2018client\u2019 data of any FreeType object. See the description of the FT_Generic type for details of usage. input The address of the FreeType object that is under finalization. Its client data is accessed through its generic field. FT_Bitmap \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Bitmap_ { unsigned int rows; unsigned int width; int pitch; unsigned char * buffer; unsigned short num_grays; unsigned char pixel_mode; unsigned char palette_mode; void * palette; } FT_Bitmap ; A structure used to describe a bitmap or pixmap to the raster. Note that we now manage pixmaps of various depths through the pixel_mode field. fields rows The number of bitmap rows. width The number of pixels in bitmap row. pitch The pitch's absolute value is the number of bytes taken by one bitmap row, including padding. However, the pitch is positive when the bitmap has a \u2018down\u2019 flow, and negative when it has an \u2018up\u2019 flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row. Note that \u2018padding\u2019 means the alignment of a bitmap to a byte border, and FreeType functions normally align to the smallest possible integer value. For the B/W rasterizer, pitch is always an even number. To change the pitch of a bitmap (say, to make it a multiple of 4), use FT_Bitmap_Convert . Alternatively, you might use callback functions to directly render to the application's surface; see the file example2.cpp in the tutorial for a demonstration. buffer A typeless pointer to the bitmap buffer. This value should be aligned on 32-bit boundaries in most cases. num_grays This field is only used with FT_PIXEL_MODE_GRAY ; it gives the number of gray levels used in the bitmap. pixel_mode The pixel mode, i.e., how pixel bits are stored. See FT_Pixel_Mode for possible values. palette_mode This field is intended for paletted pixel modes; it indicates how the palette is stored. Not used currently. palette A typeless pointer to the bitmap palette; this field is intended for paletted pixel modes. Not used currently. note width and rows refer to the physical size of the bitmap, not the logical one. For example, if FT_Pixel_Mode is set to FT_PIXEL_MODE_LCD , the logical width is a just a third of the physical one. FT_Pixel_Mode \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef enum FT_Pixel_Mode_ { FT_PIXEL_MODE_NONE = 0, FT_PIXEL_MODE_MONO , FT_PIXEL_MODE_GRAY , FT_PIXEL_MODE_GRAY2 , FT_PIXEL_MODE_GRAY4 , FT_PIXEL_MODE_LCD , FT_PIXEL_MODE_LCD_V , FT_PIXEL_MODE_BGRA , FT_PIXEL_MODE_MAX /* do not remove */ } FT_Pixel_Mode ; /* these constants are deprecated; use the corresponding ` FT_Pixel_Mode ` */ /* values instead. */ # define ft_pixel_mode_none FT_PIXEL_MODE_NONE # define ft_pixel_mode_mono FT_PIXEL_MODE_MONO # define ft_pixel_mode_grays FT_PIXEL_MODE_GRAY # define ft_pixel_mode_pal2 FT_PIXEL_MODE_GRAY2 # define ft_pixel_mode_pal4 FT_PIXEL_MODE_GRAY4 An enumeration type used to describe the format of pixels in a given bitmap. Note that additional formats may be added in the future. values FT_PIXEL_MODE_NONE Value 0 is reserved. FT_PIXEL_MODE_MONO A monochrome bitmap, using 1 bit per pixel. Note that pixels are stored in most-significant order (MSB), which means that the left-most pixel in a byte has value 128. FT_PIXEL_MODE_GRAY An 8-bit bitmap, generally used to represent anti-aliased glyph images. Each pixel is stored in one byte. Note that the number of \u2018gray\u2019 levels is stored in the num_grays field of the FT_Bitmap structure (it generally is 256). FT_PIXEL_MODE_GRAY2 A 2-bit per pixel bitmap, used to represent embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven't found a single font using this format, however. FT_PIXEL_MODE_GRAY4 A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven't found a single font using this format, however. FT_PIXEL_MODE_LCD An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on LCD displays; the bitmap is three times wider than the original glyph image. See also FT_RENDER_MODE_LCD . FT_PIXEL_MODE_LCD_V An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on rotated LCD displays; the bitmap is three times taller than the original glyph image. See also FT_RENDER_MODE_LCD_V . FT_PIXEL_MODE_BGRA [Since 2.5] An image with four 8-bit channels per pixel, representing a color image (such as emoticons) with alpha channel. For each pixel, the format is BGRA, which means, the blue channel comes first in memory. The color channels are pre-multiplied and in the sRGB colorspace.

Note that this version of FreeType only supports two image formats, even though future font drivers will be able to register their own format. values FT_GLYPH_FORMAT_NONE The value 0 is reserved. FT_GLYPH_FORMAT_COMPOSITE The glyph image is a composite of several other images. This format is only used with FT_LOAD_NO_RECURSE , and is used to report compound glyphs (like accented characters). FT_GLYPH_FORMAT_BITMAP The glyph image is a bitmap, and can be described as an FT_Bitmap . You generally need to access the bitmap field of the FT_GlyphSlotRec structure to read it. FT_GLYPH_FORMAT_OUTLINE The glyph image is a vectorial outline made of line segments and Bezier arcs; it can be described as an FT_Outline ; you generally want to access the outline field of the FT_GlyphSlotRec structure to read it. FT_GLYPH_FORMAT_PLOTTER The glyph image is a vectorial path with no inside and outside contours. Some Type 1 fonts, like those in the Hershey family, contain glyphs in this format. These are described as FT_Outline , but FreeType isn't currently capable of rendering them correctly. FT_GLYPH_FORMAT_SVG [Since 2.12] The glyph is represented by an SVG document in the \u2018SVG \u2019 table.

Note that all types and functions begin with the FTC_ prefix rather than the usual FT_ prefix in the rest of FreeType. The cache is highly portable and, thus, doesn't know anything about the fonts installed on your system, or how to access them. Therefore, it requires the following. FTC_FaceID , an arbitrary non-zero value that uniquely identifies available or installed font faces, has to be provided to the cache by the client. Note that the cache only stores and compares these values and doesn't try to interpret them in any way, but they have to be persistent on the client side. FTC_Face_Requester , a method to convert an FTC_FaceID into a new FT_Face object when necessary, has to be provided to the cache by the client. The FT_Face object is completely managed by the cache, including its termination through FT_Done_Face . To monitor termination of face objects, the finalizer callback in the generic field of the FT_Face object can be used, which might also be used to store the FTC_FaceID of the face. Clients are free to map face IDs to anything useful. The most simple usage is, for example, to associate them to a {pathname,face_index} pair that is then used by FTC_Face_Requester to call FT_New_Face . However, more complex schemes are also possible. Note that for the cache to work correctly, the face ID values must be persistent , which means that the contents they point to should not change at runtime, or that their value should not become invalid. If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call FTC_Manager_RemoveFaceID as soon as possible to let the cache get rid of any references to the old FTC_FaceID it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes in FTC_Face_Requester . To use the cache, start with calling FTC_Manager_New to create a new FTC_Manager object, which models a single cache instance. You can then look up FT_Face and FT_Size objects with FTC_Manager_LookupFace and FTC_Manager_LookupSize , respectively, and use them in any FreeType work stream. You can also cache other FreeType objects as follows. If you want to use the charmap caching, call FTC_CMapCache_New , then later use FTC_CMapCache_Lookup to perform the equivalent of FT_Get_Char_Index , only much faster. If you want to use the FT_Glyph caching, call FTC_ImageCache_New , then later use FTC_ImageCache_Lookup to retrieve the corresponding FT_Glyph objects from the cache. If you need lots of small bitmaps, it is much more memory-efficient to call FTC_SBitCache_New followed by FTC_SBitCache_Lookup . This returns FTC_SBitRec structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers). FTC_Manager \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ManagerRec_* FTC_Manager ; This object corresponds to one instance of the cache-subsystem. It is used to cache one or more FT_Face objects, along with corresponding FT_Size objects. The manager intentionally limits the total number of opened FT_Face and FT_Size objects to control memory usage. See the max_faces and max_sizes parameters of FTC_Manager_New . The manager is also used to cache \u2018nodes\u2019 of various types while limiting their total memory usage. All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones. FTC_FaceID \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef FT_Pointer FTC_FaceID ; An opaque pointer type that is used to identity face objects. The contents of such objects is application-dependent. These pointers are typically used to point to a user-defined structure containing a font file path, and face index. note Never use NULL as a valid FTC_FaceID . Face IDs are passed by the client to the cache manager that calls, when needed, the FTC_Face_Requester to translate them into new FT_Face objects. If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call FTC_Manager_RemoveFaceID before any other cache function. Failure to do so will result in incorrect behaviour or even memory leaks and crashes. FTC_Face_Requester \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef FT_Error (* FTC_Face_Requester )( FTC_FaceID face_id, FT_Library library, FT_Pointer req_data, FT_Face * aface ); A callback function provided by client applications. It is used by the cache manager to translate a given FTC_FaceID into a new valid FT_Face object, on demand. input face_id The face ID to resolve. library A handle to a FreeType library object. req_data Application-provided request data (see note below). output aface A new FT_Face handle. return FreeType error code. 0 means success. note The third parameter req_data is the same as the one passed by the client when FTC_Manager_New is called. The face requester should not perform funny things on the returned face object, like creating a new FT_Size for it, or setting a transformation through FT_Set_Transform ! FTC_Manager_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_New ( FT_Library library, FT_UInt max_faces, FT_UInt max_sizes, FT_ULong max_bytes, FTC_Face_Requester requester, FT_Pointer req_data, FTC_Manager *amanager ); Create a new cache manager. input library The parent FreeType library handle to use. max_faces Maximum number of opened FT_Face objects managed by this cache instance. Use 0 for defaults. max_sizes Maximum number of opened FT_Size objects managed by this cache instance. Use 0 for defaults. max_bytes Maximum number of bytes to use for cached data nodes. Use 0 for defaults. Note that this value does not account for managed FT_Face and FT_Size objects. requester An application-provided callback used to translate face IDs into real FT_Face objects. req_data A generic pointer that is passed to the requester each time it is called (see FTC_Face_Requester ). output amanager A handle to a new manager object. 0 in case of failure. return FreeType error code. 0 means success. FTC_Manager_Reset \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_Reset ( FTC_Manager manager ); Empty a given cache manager. This simply gets rid of all the currently cached FT_Face and FT_Size objects within the manager. inout manager A handle to the manager. FTC_Manager_Done \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_Done ( FTC_Manager manager ); Destroy a given manager after emptying it. input manager A handle to the target cache manager object. FTC_Manager_LookupFace \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_LookupFace ( FTC_Manager manager, FTC_FaceID face_id, FT_Face *aface ); Retrieve the FT_Face object that corresponds to a given face ID through a cache manager. input manager A handle to the cache manager. face_id The ID of the face object. output aface A handle to the face object. return FreeType error code. 0 means success. note The returned FT_Face object is always owned by the manager. You should never try to discard it yourself. The FT_Face object doesn't necessarily have a current size object (i.e., face->size can be 0). If you need a specific \u2018font size\u2019, use FTC_Manager_LookupSize instead. Never change the face's transformation matrix (i.e., never call the FT_Set_Transform function) on a returned face! If you need to transform glyphs, do it yourself after glyph loading. When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed. If a lookup fails with FT_Err_Out_Of_Memory the cache has already been completely flushed, and still no memory was available for the operation. FTC_Manager_LookupSize \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_Manager_LookupSize ( FTC_Manager manager, FTC_Scaler scaler, FT_Size *asize ); Retrieve the FT_Size object that corresponds to a given FTC_ScalerRec pointer through a cache manager. input manager A handle to the cache manager. scaler A scaler handle. output asize A handle to the size object. return FreeType error code. 0 means success. note The returned FT_Size object is always owned by the manager. You should never try to discard it by yourself. You can access the parent FT_Face object simply as size->face if you need it. Note that this object is also owned by the manager. note When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed. If a lookup fails with FT_Err_Out_Of_Memory the cache has already been completely flushed, and still no memory is available for the operation. FTC_Manager_RemoveFaceID \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Manager_RemoveFaceID ( FTC_Manager manager, FTC_FaceID face_id ); A special function used to indicate to the cache manager that a given FTC_FaceID is no longer valid, either because its content changed, or because it was deallocated or uninstalled. input manager The cache manager handle. face_id The FTC_FaceID to be removed. note This function flushes all nodes from the cache corresponding to this face_id , with the exception of nodes with a non-null reference count. Such nodes are however modified internally so as to never appear in later lookups with the same face_id value, and to be immediately destroyed when released by all their users. FTC_Node \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_NodeRec_* FTC_Node ; An opaque handle to a cache node object. Each cache node is reference-counted. A node with a count of 0 might be flushed out of a full cache whenever a lookup request is performed. If you look up nodes, you have the ability to \u2018acquire\u2019 them, i.e., to increment their reference count. This will prevent the node from being flushed out of the cache until you explicitly \u2018release\u2019 it (see FTC_Node_Unref ). See also FTC_SBitCache_Lookup and FTC_ImageCache_Lookup . FTC_Node_Unref \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( void ) FTC_Node_Unref ( FTC_Node node, FTC_Manager manager ); Decrement a cache node's internal reference count. When the count reaches 0, it is not destroyed but becomes eligible for subsequent cache flushes. input node The cache node handle. manager The cache manager handle. FTC_ImageCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ImageCacheRec_* FTC_ImageCache ; A handle to a glyph image cache object. They are designed to hold many distinct glyph images while not exceeding a certain memory threshold. FTC_ImageCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_ImageCache_New ( FTC_Manager manager, FTC_ImageCache *acache ); Create a new glyph image cache. input manager The parent manager for the image cache. output acache A handle to the new glyph image cache object. return FreeType error code. 0 means success. FTC_ImageCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_ImageCache_Lookup ( FTC_ImageCache cache, FTC_ImageType type, FT_UInt gindex, FT_Glyph *aglyph, FTC_Node *anode ); Retrieve a given glyph image from a glyph image cache. input cache A handle to the source glyph image cache. type A pointer to a glyph image type descriptor. gindex The glyph index to retrieve. output aglyph The corresponding FT_Glyph object. 0 in case of failure. anode Used to return the address of the corresponding cache node after incrementing its reference count (see note below). return FreeType error code. 0 means success. note The returned glyph is owned and managed by the glyph image cache. Never try to transform or discard it manually! You can however create a copy with FT_Glyph_Copy and modify the new one. If anode is not NULL , it receives the address of the cache node containing the glyph image, after increasing its reference count. This ensures that the node (as well as the FT_Glyph ) will always be kept in the cache until you call FTC_Node_Unref to \u2018release\u2019 it. If anode is NULL , the cache node is left unchanged, which means that the FT_Glyph could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent! FTC_SBit \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_SBitRec_* FTC_SBit ; A handle to a small bitmap descriptor. See the FTC_SBitRec structure for details. FTC_SBitCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_SBitCacheRec_* FTC_SBitCache ; A handle to a small bitmap cache. These are special cache objects used to store small glyph bitmaps (and anti-aliased pixmaps) in a much more efficient way than the traditional glyph image cache implemented by FTC_ImageCache . FTC_SBitCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_SBitCache_New ( FTC_Manager manager, FTC_SBitCache *acache ); Create a new cache to store small glyph bitmaps. input manager A handle to the source cache manager. output acache A handle to the new sbit cache. NULL in case of error. return FreeType error code. 0 means success. FTC_SBitCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_SBitCache_Lookup ( FTC_SBitCache cache, FTC_ImageType type, FT_UInt gindex, FTC_SBit *sbit, FTC_Node *anode ); Look up a given small glyph bitmap in a given sbit cache and \u2018lock\u2019 it to prevent its flushing from the cache until needed. input cache A handle to the source sbit cache. type A pointer to the glyph image type descriptor. gindex The glyph index. output sbit A handle to a small bitmap descriptor. anode Used to return the address of the corresponding cache node after incrementing its reference count (see note below). return FreeType error code. 0 means success. note The small bitmap descriptor and its bit buffer are owned by the cache and should never be freed by the application. They might as well disappear from memory on the next cache lookup, so don't treat them as persistent data. The descriptor's buffer field is set to 0 to indicate a missing glyph bitmap. If anode is not NULL , it receives the address of the cache node containing the bitmap, after increasing its reference count. This ensures that the node (as well as the image) will always be kept in the cache until you call FTC_Node_Unref to \u2018release\u2019 it. If anode is NULL , the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent! FTC_CMapCache \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_CMapCacheRec_* FTC_CMapCache ; An opaque handle used to model a charmap cache. This cache is to hold character codes -> glyph indices mappings. FTC_CMapCache_New \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_Error ) FTC_CMapCache_New ( FTC_Manager manager, FTC_CMapCache *acache ); Create a new charmap cache. input manager A handle to the cache manager. output acache A new cache handle. NULL in case of error. return FreeType error code. 0 means success. note Like all other caches, this one will be destroyed with the cache manager. FTC_CMapCache_Lookup \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). FT_EXPORT( FT_UInt ) FTC_CMapCache_Lookup ( FTC_CMapCache cache, FTC_FaceID face_id, FT_Int cmap_index, FT_UInt32 char_code ); Translate a character code into a glyph index, using the charmap cache. input cache A charmap cache handle. face_id The source face ID. cmap_index The index of the charmap in the source face. Any negative value means to use the cache FT_Face 's default charmap. char_code The character code (in the corresponding charmap). return Glyph index. 0 means \u2018no glyph\u2019. FTC_ScalerRec \u00b6 Defined in FT_CACHE_H (freetype/ftcache.h). typedef struct FTC_ScalerRec_ { FTC_FaceID face_id; FT_UInt width; FT_UInt height; FT_Int pixel; FT_UInt x_res; FT_UInt y_res; } FTC_ScalerRec ; A structure used to describe a given character size in either pixels or points to the cache manager. See FTC_Manager_LookupSize . fields face_id The source face ID. width The character width. height The character height. pixel A Boolean. If 1, the width and height fields are interpreted as integer pixel character sizes. Otherwise, they are expressed as 1/64 of points. x_res Only used when pixel is value 0 to indicate the horizontal resolution in dpi. y_res Only used when pixel is value 0 to indicate the vertical resolution in dpi. note This type is mainly used to retrieve FT_Size objects through the cache manager.

Sometimes the vertical stems may be only partially black. In this context, \u2018anti-aliasing\u2019 means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance. There are two principles behind this approach. 1) No hinting in the horizontal direction: Unlike \u2018superhinted\u2019 TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is \u2018faithful to the design\u2019 in representing both the glyph width and the inter-glyph spacing designed for the font.

Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied. One of the reasons to not hint horizontally is anti-aliasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale anti-aliasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would. 2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of \u2153 pixels) is less of a problem. On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called \u2018blue zones\u2019) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.

The list of available charmaps in a face is available through the face->num_charmaps and face->charmaps fields of FT_FaceRec . The currently active charmap is available as face->charmap . You should call FT_Set_Charmap to change it. note When a new face is created (either through FT_New_Face or FT_Open_Face ), the library looks for a Unicode charmap within the list and automatically activates it. If there is no Unicode charmap, FreeType doesn't set an \u2018active\u2019 charmap. also See FT_CharMapRec for the publicly accessible fields of a given character map.

FT_ENCODING_UNICODE The Unicode character set. This value covers all versions of the Unicode repertoire, including ASCII and Latin-1. Most fonts include a Unicode charmap, but not all of them. For example, if you want to access Unicode value U+1F028 (and the font contains it), use value 0x1F028 as the input value for FT_Get_Char_Index .

FT_ENCODING_MS_JOHAB Same as FT_ENCODING_JOHAB. Deprecated. note When loading a font, FreeType makes a Unicode charmap active if possible (either if the font provides such a charmap, or if FreeType can synthesize one from PostScript glyph name dictionaries; in either case, the charmap is tagged with FT_ENCODING_UNICODE ). If such a charmap is synthesized, it is placed at the first position of the charmap array. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, FT_ENCODING_NONE is used. FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE ). Use FT_Get_BDF_Charset_ID to find out which encoding is really present. If, for example, the cs_registry field is \u2018KOI8\u2019 and the cs_encoding field is \u2018R\u2019, the font is encoded in KOI8-R. FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver. Use FT_Get_WinFNT_Header and examine the charset field of the FT_WinFNT_HeaderRec structure to find out which encoding is really present. For example, FT_WinFNT_ID_CP1251 (204) means Windows code page 1251 (for Russian). FT_ENCODING_NONE is set if platform_id is TT_PLATFORM_MACINTOSH and encoding_id is not TT_MAC_ID_ROMAN (otherwise it is set to FT_ENCODING_APPLE_ROMAN ). If platform_id is TT_PLATFORM_MACINTOSH , use the function FT_Get_CMap_Language_ID to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt to get an idea how to do that. Basically, if the language ID is 0, don't use it, otherwise subtract 1 from the language ID. Then examine encoding_id . If, for example, encoding_id is TT_MAC_ID_ROMAN and the language ID (minus 1) is TT_MAC_LANGID_GREEK , it is the Greek encoding, not Roman. TT_MAC_ID_ARABIC with TT_MAC_LANGID_FARSI means the Farsi variant of the Arabic encoding.

It is used to define \u2018encoding\u2019 identifiers (see FT_Encoding ). note Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this: #define FT_ENC_TAG( value, a, b, c, d ) value to get a simple enumeration without assigning special numbers.

FT_EXPORT( FT_Error ) FT_Select_Charmap ( FT_Face face, FT_Encoding encoding ); Select a given charmap by its encoding tag (as listed in freetype.h ). inout face A handle to the source face object. input encoding A handle to the selected encoding. return FreeType error code. 0 means success. note This function returns an error if no charmap in the face corresponds to the encoding queried here. Because many fonts contain more than a single cmap for Unicode encoding, this function has some special code to select the one that covers Unicode best (\u2018best\u2019 in the sense that a UCS-4 cmap is preferred to a UCS-2 cmap). It is thus preferable to FT_Set_Charmap in this case. FT_Set_Charmap \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Charmap ( FT_Face face, FT_CharMap charmap ); Select a given charmap for character code to glyph index mapping. inout face A handle to the source face object. input charmap A handle to the selected charmap. return FreeType error code. 0 means success. note This function returns an error if the charmap is not part of the face (i.e., if it is not listed in the face->charmaps table). It also fails if an OpenType type 14 charmap is selected (which doesn't map character codes to glyph indices at all). FT_Get_Charmap_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Int ) FT_Get_Charmap_Index ( FT_CharMap charmap ); Retrieve index of a given charmap. input charmap A handle to a charmap. return The index into the array of character maps within the face to which charmap belongs. If an error occurs, -1 is returned. FT_Get_Char_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_UInt ) FT_Get_Char_Index ( FT_Face face, FT_ULong charcode ); Return the glyph index of a given character code. This function uses the currently selected charmap to do the mapping. input face A handle to the source face object. charcode The character code. return The glyph index. 0 means \u2018undefined character code\u2019. note If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the \u2018missing glyph\u2019. If the first glyph is not named \u2018.notdef\u2019, then for Type 1 and Type 42 fonts, \u2018.notdef\u2019 will be moved into the glyph ID 0 position, and whatever was there will be moved to the position \u2018.notdef\u2019 had. For Type 1 fonts, if there is no \u2018.notdef\u2019 glyph at all, then one will be created at index 0 and whatever was there will be moved to the last index \u2013 Type 42 fonts are considered invalid under this condition. FT_Get_First_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_ULong ) FT_Get_First_Char ( FT_Face face, FT_UInt *agindex ); Return the first character code in the current charmap of a given face, together with its corresponding glyph index. input face A handle to the source face object. output agindex Glyph index of first character code. 0 if charmap is empty. return The charmap's first character code. note You should use this function together with FT_Get_Next_Char to parse all character codes available in a given charmap. The code should look like this: FT_ULong charcode; FT_UInt gindex; charcode = FT_Get_First_Char( face, &gindex ); while ( gindex != 0 ) { ... do something with (charcode,gindex) pair ... charcode = FT_Get_Next_Char( face, charcode, &gindex ); } Be aware that character codes can have values up to 0xFFFFFFFF; this might happen for non-Unicode or malformed cmaps. However, even with regular Unicode encoding, so-called \u2018last resort fonts\u2019 (using SFNT cmap format 13, see function FT_Get_CMap_Format ) normally have entries for all Unicode characters up to 0x1FFFFF, which can cause a lot of iterations. Note that *agindex is set to 0 if the charmap is empty. The result itself can be 0 in two cases: if the charmap is empty or if the value 0 is the first valid character code. FT_Get_Next_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_ULong ) FT_Get_Next_Char ( FT_Face face, FT_ULong char_code, FT_UInt *agindex ); Return the next character code in the current charmap of a given face following the value char_code , as well as the corresponding glyph index. input face A handle to the source face object. char_code The starting character code. output agindex Glyph index of next character code. 0 if charmap is empty. return The charmap's next character code. note You should use this function with FT_Get_First_Char to walk over all character codes available in a given charmap. See the note for that function for a simple code example. Note that *agindex is set to 0 when there are no more codes in the charmap. FT_Load_Char \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Load_Char ( FT_Face face, FT_ULong char_code, FT_Int32 load_flags ); Load a glyph into the glyph slot of a face object, accessed by its character code. inout face A handle to a target face object where the glyph is loaded. input char_code The glyph's character code, according to the current charmap used in the face. load_flags A flag indicating what to load for this glyph. The FT_LOAD_XXX constants can be used to control the glyph loading process (e.g., whether the outline should be scaled, whether to load bitmaps or not, whether to hint the outline, etc). return FreeType error code. 0 means success. note This function simply calls FT_Get_Char_Index and FT_Load_Glyph . Many fonts contain glyphs that can't be loaded by this function since its glyph indices are not listed in any of the font's charmaps. If no active cmap is set up (i.e., face->charmap is zero), the call to FT_Get_Char_Index is omitted, and the function behaves identically to FT_Load_Glyph .","title":"Character Mapping"},{"location":"ft2-character_mapping.html#character-mapping","text":"","title":"Character Mapping"},{"location":"ft2-character_mapping.html#synopsis","text":"This section holds functions and structures that are related to mapping character input codes to glyph indices.

FT_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_FaceRec_* FT_Face ; A handle to a typographic face object. A face object models a given typeface, in a given style. note A face object also owns a single FT_GlyphSlot object, as well as one or more FT_Size objects. Use FT_New_Face or FT_Open_Face to create a new face object from a given filepath or a custom input stream. Use FT_Done_Face to destroy it (along with its slot and sizes). An FT_Face object can only be safely used from one thread at a time. Similarly, creation and destruction of FT_Face with the same FT_Library object can only be done from one thread at a time. On the other hand, functions like FT_Load_Glyph and its siblings are thread-safe and do not need the lock to be held as long as the same FT_Face object is not used from multiple threads at the same time. also See FT_FaceRec for the publicly accessible fields of a given face object.

A face object models a typeface in a font file. fields num_faces The number of faces in the font file. Some font formats can have multiple faces in a single font file. face_index This field holds two different values. Bits 0-15 are the index of the face in the font file (starting with value 0). They are set to 0 if there is only one face in the font file. [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation fonts only, holding the named instance index for the current face index (starting with value 1; value 0 indicates font access without a named instance). For non-variation fonts, bits 16-30 are ignored. If we have the third named instance of face 4, say, face_index is set to 0x00030004. Bit 31 is always zero (that is, face_index is always a positive value). [Since 2.9] Changing the design coordinates with FT_Set_Var_Design_Coordinates or FT_Set_Var_Blend_Coordinates does not influence the named instance index value (only FT_Set_Named_Instance does that). face_flags A set of bit flags that give important information about the face; see FT_FACE_FLAG_XXX for the details. style_flags The lower 16 bits contain a set of bit flags indicating the style of the face; see FT_STYLE_FLAG_XXX for the details. [Since 2.6.1] Bits 16-30 hold the number of named instances available for the current face if we have a GX or OpenType variation (sub)font. Bit 31 is always zero (that is, style_flags is always a positive value). Note that a variation font has always at least one named instance, namely the default instance. num_glyphs The number of glyphs in the face. If the face is scalable and has sbits (see num_fixed_sizes ), it is set to the number of outline glyphs. For CID-keyed fonts (not in an SFNT wrapper) this value gives the highest CID used in the font. family_name The face's family name. This is an ASCII string, usually in English, that describes the typeface's family (like \u2018Times New Roman\u2019, \u2018Bodoni\u2019, \u2018Garamond\u2019, etc). This is a least common denominator used to list fonts. Some formats (TrueType & OpenType) provide localized and Unicode versions of this string. Applications should use the format-specific interface to access them. Can be NULL (e.g., in fonts embedded in a PDF file). In case the font doesn't provide a specific family name entry, FreeType tries to synthesize one, deriving it from other name entries. style_name The face's style name. This is an ASCII string, usually in English, that describes the typeface's style (like \u2018Italic\u2019, \u2018Bold\u2019, \u2018Condensed\u2019, etc). Not all font formats provide a style name, so this field is optional, and can be set to NULL . As for family_name , some formats provide localized and Unicode versions of this string. Applications should use the format-specific interface to access them. num_fixed_sizes The number of bitmap strikes in the face. Even if the face is scalable, there might still be bitmap strikes, which are called \u2018sbits\u2019 in that case. available_sizes An array of FT_Bitmap_Size for all bitmap strikes in the face. It is set to NULL if there is no bitmap strike. Note that FreeType tries to sanitize the strike data since they are sometimes sloppy or incorrect, but this can easily fail. num_charmaps The number of charmaps in the face. charmaps An array of the charmaps of the face. generic A field reserved for client uses. See the FT_Generic type description. bbox The font bounding box. Coordinates are expressed in font units (see units_per_EM ). The box is large enough to contain any glyph from the font. Thus, bbox.yMax can be seen as the \u2018maximum ascender\u2019, and bbox.yMin as the \u2018minimum descender\u2019. Only relevant for scalable formats. Note that the bounding box might be off by (at least) one pixel for hinted fonts. See FT_Size_Metrics for further discussion. Note that the bounding box does not vary in OpenType variation fonts and should only be used in relation to the default instance. units_per_EM The number of font units per EM square for this face. This is typically 2048 for TrueType fonts, and 1000 for Type 1 fonts. Only relevant for scalable formats. ascender The typographic ascender of the face, expressed in font units. For font formats not having this information, it is set to bbox.yMax . Only relevant for scalable formats. descender The typographic descender of the face, expressed in font units. For font formats not having this information, it is set to bbox.yMin . Note that this field is negative for values below the baseline. Only relevant for scalable formats. height This value is the vertical distance between two consecutive baselines, expressed in font units. It is always positive. Only relevant for scalable formats. If you want the global glyph height, use ascender - descender . max_advance_width The maximum advance width, in font units, for all glyphs in this face. This can be used to make word wrapping computations faster. Only relevant for scalable formats. max_advance_height The maximum advance height, in font units, for all glyphs in this face. This is only relevant for vertical layouts, and is set to height for fonts that do not provide vertical metrics. Only relevant for scalable formats. underline_position The position, in font units, of the underline line for this face. It is the center of the underlining stem. Only relevant for scalable formats. underline_thickness The thickness, in font units, of the underline for this face. Only relevant for scalable formats. glyph The face's associated glyph slot(s). size The current active size for this face. charmap The current active charmap for this face. note Fields may be changed after a call to FT_Attach_File or FT_Attach_Stream . For an OpenType variation font, the values of the following fields can change after a call to FT_Set_Var_Design_Coordinates (and friends) if the font contains an \u2018MVAR\u2019 table: ascender , descender , height , underline_position , and underline_thickness . Especially for TrueType fonts see also the documentation for FT_Size_Metrics .

They inform client applications of properties of the corresponding face. values FT_FACE_FLAG_SCALABLE The face contains outline glyphs. Note that a face can contain bitmap strikes also, i.e., a face can have both this flag and FT_FACE_FLAG_FIXED_SIZES set. FT_FACE_FLAG_FIXED_SIZES The face contains bitmap strikes. See also the num_fixed_sizes and available_sizes fields of FT_FaceRec . FT_FACE_FLAG_FIXED_WIDTH The face contains fixed-width characters (like Courier, Lucida, MonoType, etc.). FT_FACE_FLAG_SFNT The face uses the SFNT storage scheme. For now, this means TrueType and OpenType. FT_FACE_FLAG_HORIZONTAL The face contains horizontal glyph metrics. This should be set for all common formats. FT_FACE_FLAG_VERTICAL The face contains vertical glyph metrics. This is only available in some formats, not all of them. FT_FACE_FLAG_KERNING The face contains kerning information. If set, the kerning distance can be retrieved using the function FT_Get_Kerning . Otherwise the function always returns the vector (0,0). Note that FreeType doesn't handle kerning data from the SFNT \u2018GPOS\u2019 table (as present in many OpenType fonts). FT_FACE_FLAG_FAST_GLYPHS THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. FT_FACE_FLAG_MULTIPLE_MASTERS The face contains multiple masters and is capable of interpolating between them. Supported formats are Adobe MM, TrueType GX, and OpenType variation fonts. See section \u2018 Multiple Masters \u2019 for API details. FT_FACE_FLAG_GLYPH_NAMES The face contains glyph names, which can be retrieved using FT_Get_Glyph_Name . Note that some TrueType fonts contain broken glyph name tables. Use the function FT_Has_PS_Glyph_Names when needed. FT_FACE_FLAG_EXTERNAL_STREAM Used internally by FreeType to indicate that a face's stream was provided by the client application and should not be destroyed when FT_Done_Face is called. Don't read or test this flag. FT_FACE_FLAG_HINTER The font driver has a hinting machine of its own. For example, with TrueType fonts, it makes sense to use data from the SFNT \u2018gasp\u2019 table only if the native TrueType hinting engine (with the bytecode interpreter) is available and active. FT_FACE_FLAG_CID_KEYED The face is CID-keyed. In that case, the face is not accessed by glyph indices but by CID values. For subsetted CID-keyed fonts this has the consequence that not all index values are a valid argument to FT_Load_Glyph . Only the CID values for which corresponding glyphs in the subsetted font exist make FT_Load_Glyph return successfully; in all other cases you get an FT_Err_Invalid_Argument error. Note that CID-keyed fonts that are in an SFNT wrapper (that is, all OpenType/CFF fonts) don't have this flag set since the glyphs are accessed in the normal way (using contiguous indices); the \u2018CID-ness\u2019 isn't visible to the application. FT_FACE_FLAG_TRICKY The face is \u2018tricky\u2019, that is, it always needs the font format's native hinting engine to get a reasonable result. A typical example is the old Chinese font mingli.ttf (but not mingliu.ttc ) that uses TrueType bytecode instructions to move and scale all of its subglyphs. It is not possible to auto-hint such fonts using FT_LOAD_FORCE_AUTOHINT ; it will also ignore FT_LOAD_NO_HINTING . You have to set both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT to really disable hinting; however, you probably never want this except for demonstration purposes. Currently, there are about a dozen TrueType fonts in the list of tricky fonts; they are hard-coded in file ttobjs.c . FT_FACE_FLAG_COLOR [Since 2.5.1] The face has color glyph tables. See FT_LOAD_COLOR for more information. FT_FACE_FLAG_VARIATION [Since 2.9] Set if the current face (or named instance) has been altered with FT_Set_MM_Design_Coordinates , FT_Set_Var_Design_Coordinates , FT_Set_Var_Blend_Coordinates , or FT_Set_MM_WeightVector to select a non-default instance. FT_FACE_FLAG_SVG [Since 2.12] The face has an \u2018SVG \u2019 OpenType table. FT_FACE_FLAG_SBIX [Since 2.12] The face has an \u2018sbix\u2019 OpenType table and outlines. For such fonts, FT_FACE_FLAG_SCALABLE is not set by default to retain backward compatibility. FT_FACE_FLAG_SBIX_OVERLAY [Since 2.12] The face has an \u2018sbix\u2019 OpenType table where outlines should be drawn on top of bitmap strikes. FT_STYLE_FLAG_XXX \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_STYLE_FLAG_ITALIC ( 1 << 0 ) # define FT_STYLE_FLAG_BOLD ( 1 << 1 ) A list of bit flags to indicate the style of a given face. These are used in the style_flags field of FT_FaceRec . values FT_STYLE_FLAG_ITALIC The face style is italic or oblique. FT_STYLE_FLAG_BOLD The face is bold. note The style information as provided by FreeType is very basic. More details are beyond the scope and should be done on a higher level (for example, by analyzing various fields of the \u2018OS/2\u2019 table in SFNT based fonts). FT_New_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_New_Face ( FT_Library library, const char * filepathname, FT_Long face_index, FT_Face *aface ); Call FT_Open_Face to open a font by its pathname. inout library A handle to the library resource. input pathname A path to the font file. face_index See FT_Open_Face for a detailed description of this parameter. output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note The pathname string should be recognizable as such by a standard fopen call on your system; in particular, this means that pathname must not contain null bytes. If that is not sufficient to address all file name possibilities (for example, to handle wide character file names on Windows in UTF-16 encoding) you might use FT_Open_Face to pass a memory array or a stream object instead. Use FT_Done_Face to destroy the created FT_Face object (along with its slot and sizes). FT_Done_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Done_Face ( FT_Face face ); Discard a given face object, as well as all of its child slots and sizes. input face A handle to a target face object. return FreeType error code. 0 means success. note See the discussion of reference counters in the description of FT_Reference_Face . FT_Reference_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Reference_Face ( FT_Face face ); A counter gets initialized to 1 at the time an FT_Face structure is created. This function increments the counter. FT_Done_Face then only destroys a face if the counter is 1, otherwise it simply decrements the counter. This function helps in managing life-cycles of structures that reference FT_Face objects. input face A handle to a target face object. return FreeType error code. 0 means success. since 2.4.2 FT_New_Memory_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_New_Memory_Face ( FT_Library library, const FT_Byte * file_base, FT_Long file_size, FT_Long face_index, FT_Face *aface ); Call FT_Open_Face to open a font that has been loaded into memory. inout library A handle to the library resource. input file_base A pointer to the beginning of the font data. file_size The size of the memory chunk used by the font data. face_index See FT_Open_Face for a detailed description of this parameter. output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note You must not deallocate the memory before calling FT_Done_Face . FT_Face_Properties \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Face_Properties ( FT_Face face, FT_UInt num_properties, FT_Parameter * properties ); Set or override certain (library or module-wide) properties on a face-by-face basis. Useful for finer-grained control and avoiding locks on shared structures (threads can modify their own faces as they see fit). Contrary to FT_Property_Set , this function uses FT_Parameter so that you can pass multiple properties to the target face in one call. Note that only a subset of the available properties can be controlled. FT_PARAM_TAG_STEM_DARKENING (stem darkening, corresponding to the property no-stem-darkening provided by the \u2018autofit\u2019, \u2018cff\u2019, \u2018type1\u2019, and \u2018t1cid\u2019 modules; see no-stem-darkening ). FT_PARAM_TAG_LCD_FILTER_WEIGHTS (LCD filter weights, corresponding to function FT_Library_SetLcdFilterWeights ). FT_PARAM_TAG_RANDOM_SEED (seed value for the CFF, Type 1, and CID \u2018random\u2019 operator, corresponding to the random-seed property provided by the \u2018cff\u2019, \u2018type1\u2019, and \u2018t1cid\u2019 modules; see random-seed ). Pass NULL as data in FT_Parameter for a given tag to reset the option and use the library or module default again. input face A handle to the source face object. num_properties The number of properties that follow. properties A handle to an FT_Parameter array with num_properties elements. return FreeType error code. 0 means success. example Here is an example that sets three properties. You must define FT_CONFIG_OPTION_SUBPIXEL_RENDERING to make the LCD filter examples work. FT_Parameter property1; FT_Bool darken_stems = 1; FT_Parameter property2; FT_LcdFiveTapFilter custom_weight = { 0x11, 0x44, 0x56, 0x44, 0x11 }; FT_Parameter property3; FT_Int32 random_seed = 314159265; FT_Parameter properties[3] = { property1, property2, property3 }; property1.tag = FT_PARAM_TAG_STEM_DARKENING; property1.data = &darken_stems; property2.tag = FT_PARAM_TAG_LCD_FILTER_WEIGHTS; property2.data = custom_weight; property3.tag = FT_PARAM_TAG_RANDOM_SEED; property3.data = &random_seed; FT_Face_Properties( face, 3, properties ); The next example resets a single property to its default value. FT_Parameter property; property.tag = FT_PARAM_TAG_LCD_FILTER_WEIGHTS; property.data = NULL; FT_Face_Properties( face, 1, &property ); since 2.8 FT_Open_Face \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Open_Face ( FT_Library library, const FT_Open_Args * args, FT_Long face_index, FT_Face *aface ); Create a face object from a given resource described by FT_Open_Args . inout library A handle to the library resource. input args A pointer to an FT_Open_Args structure that must be filled by the caller. face_index This field holds two different values. Bits 0-15 are the index of the face in the font file (starting with value 0). Set it to 0 if there is only one face in the font file. [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation fonts only, specifying the named instance index for the current face index (starting with value 1; value 0 makes FreeType ignore named instances). For non-variation fonts, bits 16-30 are ignored. Assuming that you want to access the third named instance in face 4, face_index should be set to 0x00030004. If you want to access face 4 without variation handling, simply set face_index to value 4. FT_Open_Face and its siblings can be used to quickly check whether the font format of a given font resource is supported by FreeType. In general, if the face_index argument is negative, the function's return value is 0 if the font format is recognized, or non-zero otherwise. The function allocates a more or less empty face handle in *aface (if aface isn't NULL ); the only two useful fields in this special case are face->num_faces and face->style_flags . For any negative value of face_index , face->num_faces gives the number of faces within the font file. For the negative value \u2018-(N+1)\u2019 (with \u2018N\u2019 a non-negative 16-bit value), bits 16-30 in face->style_flags give the number of named instances in face \u2018N\u2019 if we have a variation font (or zero otherwise). After examination, the returned FT_Face structure should be deallocated with a call to FT_Done_Face . output aface A handle to a new face object. If face_index is greater than or equal to zero, it must be non- NULL . return FreeType error code. 0 means success. note Unlike FreeType 1.x, this function automatically creates a glyph slot for the face object that can be accessed directly through face->glyph . Each new face object created with this function also owns a default FT_Size object, accessible as face->size . One FT_Library instance can have multiple face objects, that is, FT_Open_Face and its siblings can be called multiple times using the same library argument. See the discussion of reference counters in the description of FT_Reference_Face . If FT_OPEN_STREAM is set in args->flags , the stream in args->stream is automatically closed before this function returns any error (including FT_Err_Invalid_Argument ). example To loop over all faces, use code similar to the following snippet (omitting the error handling). ... FT_Face face; FT_Long i, num_faces; error = FT_Open_Face( library, args, -1, &face ); if ( error ) { ... } num_faces = face->num_faces; FT_Done_Face( face ); for ( i = 0; i < num_faces; i++ ) { ... error = FT_Open_Face( library, args, i, &face ); ... FT_Done_Face( face ); ... } To loop over all valid values for face_index , use something similar to the following snippet, again without error handling. The code accesses all faces immediately (thus only a single call of FT_Open_Face within the do-loop), with and without named instances. ... FT_Face face; FT_Long num_faces = 0; FT_Long num_instances = 0; FT_Long face_idx = 0; FT_Long instance_idx = 0; do { FT_Long id = ( instance_idx << 16 ) + face_idx; error = FT_Open_Face( library, args, id, &face ); if ( error ) { ... } num_faces = face->num_faces; num_instances = face->style_flags >> 16; ... FT_Done_Face( face ); if ( instance_idx < num_instances ) instance_idx++; else { face_idx++; instance_idx = 0; } } while ( face_idx < num_faces ) FT_Open_Args \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Open_Args_ { FT_UInt flags; const FT_Byte * memory_base; FT_Long memory_size; FT_String * pathname; FT_Stream stream; FT_Module driver; FT_Int num_params; FT_Parameter * params; } FT_Open_Args ; A structure to indicate how to open a new font file or stream. A pointer to such a structure can be used as a parameter for the functions FT_Open_Face and FT_Attach_Stream . fields flags A set of bit flags indicating how to use the structure. memory_base The first byte of the file in memory. memory_size The size in bytes of the file in memory. pathname A pointer to an 8-bit file pathname, which must be a C string (i.e., no null bytes except at the very end). The pointer is not owned by FreeType. stream A handle to a source stream object. driver This field is exclusively used by FT_Open_Face ; it simply specifies the font driver to use for opening the face. If set to NULL , FreeType tries to load the face with each one of the drivers in its list. num_params The number of extra parameters. params Extra parameters passed to the font driver when opening a new face. note The stream type is determined by the contents of flags : If the FT_OPEN_MEMORY bit is set, assume that this is a memory file of memory_size bytes, located at memory_address . The data are not copied, and the client is responsible for releasing and destroying them after the corresponding call to FT_Done_Face . Otherwise, if the FT_OPEN_STREAM bit is set, assume that a custom input stream stream is used. Otherwise, if the FT_OPEN_PATHNAME bit is set, assume that this is a normal file and use pathname to open it. If none of the above bits are set or if multiple are set at the same time, the flags are invalid and FT_Open_Face fails. If the FT_OPEN_DRIVER bit is set, FT_Open_Face only tries to open the file with the driver whose handler is in driver . If the FT_OPEN_PARAMS bit is set, the parameters given by num_params and params is used. They are ignored otherwise. Ideally, both the pathname and params fields should be tagged as \u2018const\u2019; this is missing for API backward compatibility. In other words, applications should treat them as read-only.

FT_Attach_Stream \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Attach_Stream ( FT_Face face, const FT_Open_Args * parameters ); \u2018Attach\u2019 data to a face object.

For example, you can attach an AFM file that comes with a Type 1 font to get the kerning values and other metrics. inout face The target face object. input parameters A pointer to FT_Open_Args that must be filled by the caller. return FreeType error code. 0 means success. note The meaning of the \u2018attach\u2019 (i.e., what really happens when the new file is read) is not fixed by FreeType itself. It really depends on the font format (and thus the font driver). Client applications are expected to know what they are doing when invoking this function.

Currently, FreeType only supports bitmap glyphs in PNG format for this table (i.e., JPEG and TIFF formats are unsupported, as are Apple-specific formats not part of the OpenType specification). note For backward compatibility, a font with an \u2018sbix\u2019 table is treated as a bitmap-only face. Using FT_Open_Face with FT_PARAM_TAG_IGNORE_SBIX , an application can switch off \u2018sbix\u2019 handling so that the face is treated as an ordinary outline font with scalable outlines. Here is some pseudo code that roughly illustrates how to implement \u2018sbix\u2019 handling according to the OpenType specification. if ( FT_HAS_SBIX( face ) ) { // open font as a scalable one without sbix handling FT_Face face2; FT_Parameter param = { FT_PARAM_TAG_IGNORE_SBIX, NULL }; FT_Open_Args args = { FT_OPEN_PARAMS | ..., ..., 1, ¶m }; FT_Open_Face( library, &args, 0, &face2 ); <sort `face->available_size` as necessary into `preferred_sizes`[*]> for ( i = 0; i < face->num_fixed_sizes; i++ ) { size = preferred_sizes[i].size; error = FT_Set_Pixel_Sizes( face, size, size ); <error handling omitted> // check whether we have a glyph in a bitmap strike error = FT_Load_Glyph( face, glyph_index, FT_LOAD_SBITS_ONLY | FT_LOAD_BITMAP_METRICS_ONLY ); if ( error == FT_Err_Invalid_Argument ) continue; else if ( error ) <other error handling omitted> else break; } if ( i != face->num_fixed_sizes ) <load embedded bitmap with `FT_Load_Glyph`, scale it, display it, etc.> if ( i == face->num_fixed_sizes || FT_HAS_SBIX_OVERLAY( face ) ) <use `face2` to load outline glyph with `FT_Load_Glyph`, scale it, display it on top of the bitmap, etc.> } [*] Assuming a target value of 400dpi and available strike sizes 100, 200, 300, and 400dpi, a possible order might be [400, 200, 300, 100]: scaling 200dpi to 400dpi usually gives better results than scaling 300dpi to 400dpi; it is also much faster. However, scaling 100dpi to 400dpi can yield a too pixelated result, thus the preference might be 300dpi over 100dpi. since 2.12 FT_HAS_SBIX_OVERLAY \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_HAS_SBIX_OVERLAY ( face ) \\ ( !!( (face)->face_flags & FT_FACE_FLAG_SBIX_OVERLAY ) ) A macro that returns true whenever a face object contains an \u2018sbix\u2019 OpenType table with bit 1 in its flags field set, instructing the application to overlay the bitmap strike with the corresponding outline glyph.

FT_Glyph_BBox_Mode \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). typedef enum FT_Glyph_BBox_Mode_ { FT_GLYPH_BBOX_UNSCALED = 0, FT_GLYPH_BBOX_SUBPIXELS = 0, FT_GLYPH_BBOX_GRIDFIT = 1, FT_GLYPH_BBOX_TRUNCATE = 2, FT_GLYPH_BBOX_PIXELS = 3 } FT_Glyph_BBox_Mode ; /* these constants are deprecated; use the corresponding */ /* ` FT_Glyph_BBox_Mode ` values instead */ # define ft_glyph_bbox_unscaled FT_GLYPH_BBOX_UNSCALED # define ft_glyph_bbox_subpixels FT_GLYPH_BBOX_SUBPIXELS # define ft_glyph_bbox_gridfit FT_GLYPH_BBOX_GRIDFIT # define ft_glyph_bbox_truncate FT_GLYPH_BBOX_TRUNCATE # define ft_glyph_bbox_pixels FT_GLYPH_BBOX_PIXELS The mode how the values of FT_Glyph_Get_CBox are returned. values FT_GLYPH_BBOX_UNSCALED Return unscaled font units. FT_GLYPH_BBOX_SUBPIXELS Return unfitted 26.6 coordinates. FT_GLYPH_BBOX_GRIDFIT Return grid-fitted 26.6 coordinates. FT_GLYPH_BBOX_TRUNCATE Return coordinates in integer pixels. FT_GLYPH_BBOX_PIXELS Return grid-fitted pixel coordinates. FT_Glyph_Get_CBox \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). FT_EXPORT( void ) FT_Glyph_Get_CBox ( FT_Glyph glyph, FT_UInt bbox_mode, FT_BBox *acbox ); Return a glyph's \u2018control box\u2019. The control box encloses all the outline's points, including Bezier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline that contains Bezier outside arcs). Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the \u2018ftbbox\u2019 component, which is dedicated to this single task. input glyph A handle to the source glyph object. mode The mode that indicates how to interpret the returned bounding box values. output acbox The glyph coordinate bounding box. Coordinates are expressed in 1/64 of pixels if it is grid-fitted. note Coordinates are relative to the glyph origin, using the y upwards convention. If the glyph has been loaded with FT_LOAD_NO_SCALE , bbox_mode must be set to FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6 pixel format. The value FT_GLYPH_BBOX_SUBPIXELS is another name for this constant. If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE , the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units. Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as: width = bbox.xMax - bbox.xMin; height = bbox.yMax - bbox.yMin; Note also that for 26.6 coordinates, if bbox_mode is set to FT_GLYPH_BBOX_GRIDFIT , the coordinates will also be grid-fitted, which corresponds to: bbox.xMin = FLOOR(bbox.xMin); bbox.yMin = FLOOR(bbox.yMin); bbox.xMax = CEILING(bbox.xMax); bbox.yMax = CEILING(bbox.yMax); To get the bbox in pixel coordinates, set bbox_mode to FT_GLYPH_BBOX_TRUNCATE . To get the bbox in grid-fitted pixel coordinates, set bbox_mode to FT_GLYPH_BBOX_PIXELS . FT_Glyph_To_Bitmap \u00b6 Defined in FT_GLYPH_H (freetype/ftglyph.h). FT_EXPORT( FT_Error ) FT_Glyph_To_Bitmap ( FT_Glyph * the_glyph, FT_Render_Mode render_mode, const FT_Vector * origin, FT_Bool destroy ); Convert a given glyph object to a bitmap glyph object. inout the_glyph A pointer to a handle to the target glyph. input render_mode An enumeration that describes how the data is rendered. origin A pointer to a vector used to translate the glyph image before rendering. Can be 0 (if no translation). The origin is expressed in 26.6 pixels. destroy A boolean that indicates that the original glyph image should be destroyed by this function. It is never destroyed in case of error. return FreeType error code. 0 means success. note This function does nothing if the glyph format isn't scalable. The glyph image is translated with the origin vector before rendering. The first parameter is a pointer to an FT_Glyph handle that will be replaced by this function (with newly allocated data). Typically, you would do something like the following (omitting error handling). FT_Glyph glyph; FT_BitmapGlyph glyph_bitmap; // load glyph error = FT_Load_Char( face, glyph_index, FT_LOAD_DEFAULT ); // extract glyph image error = FT_Get_Glyph( face->glyph, &glyph ); // convert to a bitmap (default render mode + destroying old) if ( glyph->format != FT_GLYPH_FORMAT_BITMAP ) { error = FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL, 0, 1 ); if ( error ) // `glyph' unchanged ... } // access bitmap content by typecasting glyph_bitmap = (FT_BitmapGlyph)glyph; // do funny stuff with it, like blitting/drawing ... // discard glyph image (bitmap or not) FT_Done_Glyph( glyph ); Here is another example, again without error handling.

FT_GlyphSlot \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_GlyphSlotRec_* FT_GlyphSlot ; A handle to a given \u2018glyph slot\u2019. A slot is a container that can hold any of the glyphs contained in its parent face. In other words, each time you call FT_Load_Glyph or FT_Load_Char , the slot's content is erased by the new glyph data, i.e., the glyph's metrics, its image (bitmap or outline), and other control information. also See FT_GlyphSlotRec for the publicly accessible glyph fields. FT_GlyphSlotRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_GlyphSlotRec_ { FT_Library library; FT_Face face; FT_GlyphSlot next; FT_UInt glyph_index; /* new in 2.10; was reserved previously */ FT_Generic generic; FT_Glyph_Metrics metrics; FT_Fixed linearHoriAdvance; FT_Fixed linearVertAdvance; FT_Vector advance; FT_Glyph_Format format; FT_Bitmap bitmap; FT_Int bitmap_left; FT_Int bitmap_top; FT_Outline outline; FT_UInt num_subglyphs; FT_SubGlyph subglyphs; void * control_data; long control_len; FT_Pos lsb_delta; FT_Pos rsb_delta; void * other; FT_Slot_Internal internal; } FT_GlyphSlotRec ; FreeType root glyph slot class structure. A glyph slot is a container where individual glyphs can be loaded, be they in outline or bitmap format. fields library A handle to the FreeType library instance this slot belongs to. face A handle to the parent face object. next In some cases (like some font tools), several glyph slots per face object can be a good thing. As this is rare, the glyph slots are listed through a direct, single-linked list using its next field. glyph_index [Since 2.10] The glyph index passed as an argument to FT_Load_Glyph while initializing the glyph slot. generic A typeless pointer unused by the FreeType library or any of its drivers. It can be used by client applications to link their own data to each glyph slot object. metrics The metrics of the last loaded glyph in the slot. The returned values depend on the last load flags (see the FT_Load_Glyph API function) and can be expressed either in 26.6 fractional pixels or font units. Note that even when the glyph image is transformed, the metrics are not. linearHoriAdvance The advance width of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for scalable glyphs. linearVertAdvance The advance height of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for scalable glyphs. advance This shorthand is, depending on FT_LOAD_IGNORE_TRANSFORM , the transformed (hinted) advance width for the glyph, in 26.6 fractional pixel format. As specified with FT_LOAD_VERTICAL_LAYOUT , it uses either the horiAdvance or the vertAdvance value of metrics field. format This field indicates the format of the image contained in the glyph slot. Typically FT_GLYPH_FORMAT_BITMAP , FT_GLYPH_FORMAT_OUTLINE , or FT_GLYPH_FORMAT_COMPOSITE , but other values are possible. bitmap This field is used as a bitmap descriptor. Note that the address and content of the bitmap buffer can change between calls of FT_Load_Glyph and a few other functions. bitmap_left The bitmap's left bearing expressed in integer pixels. bitmap_top The bitmap's top bearing expressed in integer pixels. This is the distance from the baseline to the top-most glyph scanline, upwards y coordinates being positive . outline The outline descriptor for the current glyph image if its format is FT_GLYPH_FORMAT_OUTLINE . Once a glyph is loaded, outline can be transformed, distorted, emboldened, etc. However, it must not be freed. [Since 2.10.1] If FT_LOAD_NO_SCALE is set, outline coordinates of OpenType variation fonts for a selected instance are internally handled as 26.6 fractional font units but returned as (rounded) integers, as expected. To get unrounded font units, don't use FT_LOAD_NO_SCALE but load the glyph with FT_LOAD_NO_HINTING and scale it, using the font's units_per_EM value as the ppem. num_subglyphs The number of subglyphs in a composite glyph. This field is only valid for the composite glyph format that should normally only be loaded with the FT_LOAD_NO_RECURSE flag. subglyphs An array of subglyph descriptors for composite glyphs. There are num_subglyphs elements in there. Currently internal to FreeType. control_data Certain font drivers can also return the control data for a given glyph image (e.g. TrueType bytecode, Type 1 charstrings, etc.). This field is a pointer to such data; it is currently internal to FreeType. control_len This is the length in bytes of the control data. Currently internal to FreeType. other Reserved. lsb_delta The difference between hinted and unhinted left side bearing while auto-hinting is active. Zero otherwise. rsb_delta The difference between hinted and unhinted right side bearing while auto-hinting is active. Zero otherwise. note If FT_Load_Glyph is called with default flags (see FT_LOAD_DEFAULT ) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type 1 formats). [Since 2.9] The prospective bitmap metrics are calculated according to FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even if FT_LOAD_RENDER is not set. This image can later be converted into a bitmap by calling FT_Render_Glyph . This function searches the current renderer for the native image's format, then invokes it. The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in slot->bitmap . Note that slot->bitmap_left and slot->bitmap_top are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, slot->format is also changed to FT_GLYPH_FORMAT_BITMAP . Here is a small pseudo code fragment that shows how to use lsb_delta and rsb_delta to do fractional positioning of glyphs: FT_GlyphSlot slot = face->glyph; FT_Pos origin_x = 0; for all glyphs do <load glyph with `FT_Load_Glyph'> FT_Outline_Translate( slot->outline, origin_x & 63, 0 ); <save glyph image, or render glyph, or ...> <compute kern between current and next glyph and add it to `origin_x'> origin_x += slot->advance.x; origin_x += slot->lsb_delta - slot->rsb_delta; endfor Here is another small pseudo code fragment that shows how to use lsb_delta and rsb_delta to improve integer positioning of glyphs: FT_GlyphSlot slot = face->glyph; FT_Pos origin_x = 0; FT_Pos prev_rsb_delta = 0; for all glyphs do <compute kern between current and previous glyph and add it to `origin_x'> <load glyph with `FT_Load_Glyph'> if ( prev_rsb_delta - slot->lsb_delta > 32 ) origin_x -= 64; else if ( prev_rsb_delta - slot->lsb_delta < -31 ) origin_x += 64; prev_rsb_delta = slot->rsb_delta; <save glyph image, or render glyph, or ...> origin_x += slot->advance.x; endfor If you use strong auto-hinting, you must apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then. FT_Glyph_Metrics \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Glyph_Metrics_ { FT_Pos width; FT_Pos height; FT_Pos horiBearingX; FT_Pos horiBearingY; FT_Pos horiAdvance; FT_Pos vertBearingX; FT_Pos vertBearingY; FT_Pos vertAdvance; } FT_Glyph_Metrics ; A structure to model the metrics of a single glyph. The values are expressed in 26.6 fractional pixel format; if the flag FT_LOAD_NO_SCALE has been used while loading the glyph, values are expressed in font units instead. fields width The glyph's width. height The glyph's height. horiBearingX Left side bearing for horizontal layout. horiBearingY Top side bearing for horizontal layout. horiAdvance Advance width for horizontal layout. vertBearingX Left side bearing for vertical layout. vertBearingY Top side bearing for vertical layout. Larger positive values mean further below the vertical glyph origin. vertAdvance Advance height for vertical layout. Positive values mean the glyph has a positive advance downward. note If not disabled with FT_LOAD_NO_HINTING , the values represent dimensions of the hinted glyph (in case hinting is applicable). Stroking a glyph with an outside border does not increase horiAdvance or vertAdvance ; you have to manually adjust these values to account for the added width and height. FreeType doesn't use the \u2018VORG\u2019 table data for CFF fonts because it doesn't have an interface to quickly retrieve the glyph height. The y coordinate of the vertical origin can be simply computed as vertBearingY + height after loading a glyph. FT_Load_Glyph \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Load_Glyph ( FT_Face face, FT_UInt glyph_index, FT_Int32 load_flags ); Load a glyph into the glyph slot of a face object. inout face A handle to the target face object where the glyph is loaded. input glyph_index The index of the glyph in the font file. For CID-keyed fonts (either in PS or in CFF format) this argument specifies the CID value. load_flags A flag indicating what to load for this glyph. The FT_LOAD_XXX flags can be used to control the glyph loading process (e.g., whether the outline should be scaled, whether to load bitmaps or not, whether to hint the outline, etc). return FreeType error code. 0 means success. note For proper scaling and hinting, the active FT_Size object owned by the face has to be meaningfully initialized by calling FT_Set_Char_Size before this function, for example. The loaded glyph may be transformed. See FT_Set_Transform for the details. For subsetted CID-keyed fonts, FT_Err_Invalid_Argument is returned for invalid CID values (that is, for CID values that don't have a corresponding glyph in the font). See the discussion of the FT_FACE_FLAG_CID_KEYED flag for more details. If you receive FT_Err_Glyph_Too_Big , try getting the glyph outline at EM size, then scale it manually and fill it as a graphics operation.

In this case, the following happens: FreeType looks for a bitmap for the glyph corresponding to the face's current size. If one is found, the function returns. The bitmap data can be accessed from the glyph slot (see note below). If no embedded bitmap is searched for or found, FreeType looks for a scalable outline. If one is found, it is loaded from the font file, scaled to device pixels, then \u2018hinted\u2019 to the pixel grid in order to optimize it. The outline data can be accessed from the glyph slot (see note below). Note that by default the glyph loader doesn't render outlines into bitmaps. The following flags are used to modify this default behaviour to more specific and useful cases. FT_LOAD_NO_SCALE Don't scale the loaded outline glyph but keep it in font units. This flag is also assumed if FT_Size owned by the face was not properly initialized. This flag implies FT_LOAD_NO_HINTING and FT_LOAD_NO_BITMAP , and unsets FT_LOAD_RENDER . If the font is \u2018tricky\u2019 (see FT_FACE_FLAG_TRICKY for more), using FT_LOAD_NO_SCALE usually yields meaningless outlines because the subglyphs must be scaled and positioned with hinting instructions. This can be solved by loading the font without FT_LOAD_NO_SCALE and setting the character size to font->units_per_EM . FT_LOAD_NO_HINTING Disable hinting. This generally generates \u2018blurrier\u2019 bitmap glyphs when the glyphs are rendered in any of the anti-aliased modes. See also the note below. This flag is implied by FT_LOAD_NO_SCALE . FT_LOAD_RENDER Call FT_Render_Glyph after the glyph is loaded. By default, the glyph is rendered in FT_RENDER_MODE_NORMAL mode. This can be overridden by FT_LOAD_TARGET_XXX or FT_LOAD_MONOCHROME . This flag is unset by FT_LOAD_NO_SCALE . FT_LOAD_NO_BITMAP Ignore bitmap strikes when loading. Bitmap-only fonts ignore this flag. FT_LOAD_NO_SCALE always sets this flag. FT_LOAD_SBITS_ONLY [Since 2.12] This is the opposite of FT_LOAD_NO_BITMAP , more or less: FT_Load_Glyph returns FT_Err_Invalid_Argument if the face contains a bitmap strike for the given size (or the strike selected by FT_Select_Size ) but there is no glyph in the strike. Note that this load flag was part of FreeType since version 2.0.6 but previously tagged as internal. FT_LOAD_VERTICAL_LAYOUT Load the glyph for vertical text layout. In particular, the advance value in the FT_GlyphSlotRec structure is set to the vertAdvance value of the metrics field. In case FT_HAS_VERTICAL doesn't return true, you shouldn't use this flag currently. Reason is that in this case vertical metrics get synthesized, and those values are not always consistent across various font formats. FT_LOAD_FORCE_AUTOHINT Prefer the auto-hinter over the font's native hinter. See also the note below. FT_LOAD_PEDANTIC Make the font driver perform pedantic verifications during glyph loading and hinting. This is mostly used to detect broken glyphs in fonts. By default, FreeType tries to handle broken fonts also. In particular, errors from the TrueType bytecode engine are not passed to the application if this flag is not set; this might result in partially hinted or distorted glyphs in case a glyph's bytecode is buggy. FT_LOAD_NO_RECURSE Don't load composite glyphs recursively. Instead, the font driver fills the num_subglyph and subglyphs values of the glyph slot; it also sets glyph->format to FT_GLYPH_FORMAT_COMPOSITE . The description of subglyphs can then be accessed with FT_Get_SubGlyph_Info . Don't use this flag for retrieving metrics information since some font drivers only return rudimentary data. This flag implies FT_LOAD_NO_SCALE and FT_LOAD_IGNORE_TRANSFORM . FT_LOAD_IGNORE_TRANSFORM Ignore the transform matrix set by FT_Set_Transform . FT_LOAD_MONOCHROME This flag is used with FT_LOAD_RENDER to indicate that you want to render an outline glyph to a 1-bit monochrome bitmap glyph, with 8 pixels packed into each byte of the bitmap data. Note that this has no effect on the hinting algorithm used. You should rather use FT_LOAD_TARGET_MONO so that the monochrome-optimized hinting algorithm is used. FT_LOAD_LINEAR_DESIGN Keep linearHoriAdvance and linearVertAdvance fields of FT_GlyphSlotRec in font units. See FT_GlyphSlotRec for details. FT_LOAD_NO_AUTOHINT Disable the auto-hinter. See also the note below. FT_LOAD_COLOR Load colored glyphs. FreeType searches in the following order; there are slight differences depending on the font format. [Since 2.5] Load embedded color bitmap images (provided FT_LOAD_NO_BITMAP is not set). The resulting color bitmaps, if available, have the FT_PIXEL_MODE_BGRA format, with pre-multiplied color channels. If the flag is not set and color bitmaps are found, they are converted to 256-level gray bitmaps, using the FT_PIXEL_MODE_GRAY format. [Since 2.12] If the glyph index maps to an entry in the face's \u2018SVG \u2019 table, load the associated SVG document from this table and set the format field of FT_GlyphSlotRec to FT_GLYPH_FORMAT_SVG ([since 2.13.1] provided FT_LOAD_NO_SVG is not set). Note that FreeType itself can't render SVG documents; however, the library provides hooks to seamlessly integrate an external renderer. See sections \u2018 The SVG driver \u2019 and \u2018 OpenType SVG Fonts \u2019 for more. [Since 2.10, experimental] If the glyph index maps to an entry in the face's \u2018COLR\u2019 table with a \u2018CPAL\u2019 palette table (as defined in the OpenType specification), make FT_Render_Glyph provide a default blending of the color glyph layers associated with the glyph index, using the same bitmap format as embedded color bitmap images. This is mainly for convenience and works only for glyphs in \u2018COLR\u2019 v0 tables (or glyphs in \u2018COLR\u2019 v1 tables that exclusively use v0 features). For full control of color layers use FT_Get_Color_Glyph_Layer and FreeType's color functions like FT_Palette_Select instead of setting FT_LOAD_COLOR for rendering so that the client application can handle blending by itself. FT_LOAD_NO_SVG [Since 2.13.1] Ignore SVG glyph data when loading. FT_LOAD_COMPUTE_METRICS [Since 2.6.1] Compute glyph metrics from the glyph data, without the use of bundled metrics tables (for example, the \u2018hdmx\u2019 table in TrueType fonts). This flag is mainly used by font validating or font editing applications, which need to ignore, verify, or edit those tables. Currently, this flag is only implemented for TrueType fonts. FT_LOAD_BITMAP_METRICS_ONLY [Since 2.7.1] Request loading of the metrics and bitmap image information of a (possibly embedded) bitmap glyph without allocating or copying the bitmap image data itself. No effect if the target glyph is not a bitmap image. This flag unsets FT_LOAD_RENDER . FT_LOAD_CROP_BITMAP Ignored. Deprecated. FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH Ignored. Deprecated. note By default, hinting is enabled and the font's native hinter (see FT_FACE_FLAG_HINTER ) is preferred over the auto-hinter. You can disable hinting by setting FT_LOAD_NO_HINTING or change the precedence by setting FT_LOAD_FORCE_AUTOHINT . You can also set FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be used at all. See the description of FT_FACE_FLAG_TRICKY for a special exception (affecting only a handful of Asian fonts). Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See FT_LOAD_TARGET_XXX for details. Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results. FT_LOAD_TARGET_MODE \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_LOAD_TARGET_MODE ( x ) \\ FT_STATIC_CAST( FT_Render_Mode , ( (x) >> 16 ) & 15 ) Return the FT_Render_Mode corresponding to a given FT_LOAD_TARGET_XXX value. FT_LOAD_TARGET_XXX \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). # define FT_LOAD_TARGET_( x ) ( FT_STATIC_CAST( FT_Int32 , (x) & 15 ) << 16 ) # define FT_LOAD_TARGET_NORMAL FT_LOAD_TARGET_( FT_RENDER_MODE_NORMAL ) # define FT_LOAD_TARGET_LIGHT FT_LOAD_TARGET_( FT_RENDER_MODE_LIGHT ) # define FT_LOAD_TARGET_MONO FT_LOAD_TARGET_( FT_RENDER_MODE_MONO ) # define FT_LOAD_TARGET_LCD FT_LOAD_TARGET_( FT_RENDER_MODE_LCD ) # define FT_LOAD_TARGET_LCD_V FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V ) A list of values to select a specific hinting algorithm for the hinter. You should OR one of these values to your load_flags when calling FT_Load_Glyph . Note that a font's native hinters may ignore the hinting algorithm you have specified (e.g., the TrueType bytecode interpreter). You can set FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used. values FT_LOAD_TARGET_NORMAL The default hinting algorithm, optimized for standard gray-level rendering. For monochrome output, use FT_LOAD_TARGET_MONO instead. FT_LOAD_TARGET_LIGHT A lighter hinting algorithm for gray-level modes. Many generated glyphs are fuzzier but better resemble their original shape. This is achieved by snapping glyphs to the pixel grid only vertically (Y-axis), as is done by FreeType's new CFF engine or Microsoft's ClearType font renderer. This preserves inter-glyph spacing in horizontal text. The snapping is done either by the native font driver, if the driver itself and the font support it, or by the auto-hinter. Advance widths are rounded to integer values; however, using the lsb_delta and rsb_delta fields of FT_GlyphSlotRec , it is possible to get fractional advance widths for subpixel positioning (which is recommended to use). If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active, TrueType-like metrics are used to make this mode behave similarly as in unpatched FreeType versions between 2.4.6 and 2.7.1 (inclusive). FT_LOAD_TARGET_MONO Strong hinting algorithm that should only be used for monochrome output. The result is probably unpleasant if the glyph is rendered in non-monochrome modes. Note that for outline fonts only the TrueType font driver has proper monochrome hinting support, provided the TTFs contain hints for B/W rendering (which most fonts no longer provide). If these conditions are not met it is very likely that you get ugly results at smaller sizes. FT_LOAD_TARGET_LCD A variant of FT_LOAD_TARGET_LIGHT optimized for horizontally decimated LCD displays. FT_LOAD_TARGET_LCD_V A variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays. note You should use only one of the FT_LOAD_TARGET_XXX values in your load_flags . They can't be ORed. If FT_LOAD_RENDER is also set, the glyph is rendered in the corresponding mode (i.e., the mode that matches the used algorithm best). An exception is FT_LOAD_TARGET_MONO since it implies FT_LOAD_MONOCHROME . You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the \u2018light\u2019 hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like FT_Load_Glyph( face, glyph_index, load_flags | FT_LOAD_TARGET_LIGHT ); FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD ); In general, you should stick with one rendering mode. For example, switching between FT_LOAD_TARGET_NORMAL and FT_LOAD_TARGET_MONO enforces a lot of recomputation for TrueType fonts, which is slow. Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits. FT_Render_Glyph \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Render_Glyph ( FT_GlyphSlot slot, FT_Render_Mode render_mode ); Convert a given glyph image to a bitmap. It does so by inspecting the glyph image format, finding the relevant renderer, and invoking it. inout slot A handle to the glyph slot containing the image to convert. input render_mode The render mode used to render the glyph image into a bitmap. See FT_Render_Mode for a list of possible values. If FT_RENDER_MODE_NORMAL is used, a previous call of FT_Load_Glyph with flag FT_LOAD_COLOR makes FT_Render_Glyph provide a default blending of colored glyph layers associated with the current glyph slot (provided the font contains such layers) instead of rendering the glyph slot's outline. This is an experimental feature; see FT_LOAD_COLOR for more information. return FreeType error code. 0 means success. note When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white). On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception. This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness \u2013 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or \u2018dirt\u2019 around it. The situation is especially ugly for diagonal stems like in \u2018w\u2019 glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't. The blending function for placing text over a background is dst = alpha * src + (1 - alpha) * dst , which is known as the OVER operator. To correctly composite an anti-aliased pixel of a glyph onto a surface, take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space, use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and apply inverse gamma to the blended pixel and write it back to the image. Internal testing at Adobe found that a target inverse gamma of 1.8 for step 3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one. This process can cost performance. There is an approximation that does not need to know about the background color; see https://bel.fi/alankila/lcd/ and https://bel.fi/alankila/lcd/alpcor.html for details. ATTENTION : Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section \u2018 Subpixel Rendering \u2019. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3 times per pixel: red foreground subpixel to red background subpixel and so on for green and blue. FT_Render_Mode \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Render_Mode_ { FT_RENDER_MODE_NORMAL = 0, FT_RENDER_MODE_LIGHT , FT_RENDER_MODE_MONO , FT_RENDER_MODE_LCD , FT_RENDER_MODE_LCD_V , FT_RENDER_MODE_SDF , FT_RENDER_MODE_MAX } FT_Render_Mode ; /* these constants are deprecated; use the corresponding */ /* ` FT_Render_Mode ` values instead */ # define ft_render_mode_normal FT_RENDER_MODE_NORMAL # define ft_render_mode_mono FT_RENDER_MODE_MONO Render modes supported by FreeType 2. Each mode corresponds to a specific type of scanline conversion performed on the outline. For bitmap fonts and embedded bitmaps the bitmap->pixel_mode field in the FT_GlyphSlotRec structure gives the format of the returned bitmap. All modes except FT_RENDER_MODE_MONO use 256 levels of opacity, indicating pixel coverage. Use linear alpha blending and gamma correction to correctly render non-monochrome glyph bitmaps onto a surface; see FT_Render_Glyph . The FT_RENDER_MODE_SDF is a special render mode that uses up to 256 distance values, indicating the signed distance from the grid position to the nearest outline. values FT_RENDER_MODE_NORMAL Default render mode; it corresponds to 8-bit anti-aliased bitmaps. FT_RENDER_MODE_LIGHT This is equivalent to FT_RENDER_MODE_NORMAL . It is only defined as a separate value because render modes are also used indirectly to define hinting algorithm selectors. See FT_LOAD_TARGET_XXX for details. FT_RENDER_MODE_MONO This mode corresponds to 1-bit bitmaps (with 2 levels of opacity). FT_RENDER_MODE_LCD This mode corresponds to horizontal RGB and BGR subpixel displays like LCD screens. It produces 8-bit bitmaps that are 3 times the width of the original glyph outline in pixels, and which use the FT_PIXEL_MODE_LCD mode. FT_RENDER_MODE_LCD_V This mode corresponds to vertical RGB and BGR subpixel displays (like PDA screens, rotated LCD displays, etc.). It produces 8-bit bitmaps that are 3 times the height of the original glyph outline in pixels and use the FT_PIXEL_MODE_LCD_V mode. FT_RENDER_MODE_SDF This mode corresponds to 8-bit, single-channel signed distance field (SDF) bitmaps. Each pixel in the SDF grid is the value from the pixel's position to the nearest glyph's outline. The distances are calculated from the center of the pixel and are positive if they are filled by the outline (i.e., inside the outline) and negative otherwise. Check the note below on how to convert the output values to usable data. note The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like FT_PIXEL_MODE_MONO . You can use FT_Bitmap_Convert to transform them into 8-bit pixmaps. For FT_RENDER_MODE_SDF the output bitmap buffer contains normalized distances that are packed into unsigned 8-bit values. To get pixel values in floating point representation use the following pseudo-C code for the conversion. // Load glyph and render using FT_RENDER_MODE_SDF, // then use the output buffer as follows. ... FT_Byte buffer = glyph->bitmap->buffer; for pixel in buffer { // `sd` is the signed distance and `spread` is the current spread; // the default spread is 2 and can be changed. float sd = (float)pixel - 128.0f; // Convert to pixel values. sd = ( sd / 128.0f ) * spread; // Store `sd` in a buffer or use as required. } FreeType has two rasterizers for generating SDF, namely: sdf for generating SDF directly from glyph's outline, and bsdf for generating SDF from rasterized bitmaps. Depending on the glyph type (i.e., outline or bitmap), one of the two rasterizers is chosen at runtime and used for generating SDFs. To force the use of bsdf you should render the glyph with any of the FreeType's other rendering modes (e.g., FT_RENDER_MODE_NORMAL ) and then re-render with FT_RENDER_MODE_SDF . There are some issues with stability and possible failures of the SDF renderers (specifically sdf ). The sdf rasterizer is sensitive to really small features (e.g., sharp turns that are less than 1 pixel) and imperfections in the glyph's outline, causing artifacts in the final output. The sdf rasterizer has limited support for handling intersecting contours and cannot handle self-intersecting contours whatsoever. Self-intersection happens when a single connected contour intersects itself at some point; having these in your font definitely poses a problem to the rasterizer and cause artifacts, too. Generating SDF for really small glyphs may result in undesirable output; the pixel grid (which stores distance information) becomes too coarse. Since the output buffer is normalized, precision at smaller spreads is greater than precision at larger spread values because the output range of [0..255] gets mapped to a smaller SDF range. A spread of 2 should be sufficient in most cases. Points (1) and (2) can be avoided by using the bsdf rasterizer, which is more stable than the sdf rasterizer in general.

This can be useful to generate \u2018bordered\u2019 glyph, i.e., glyphs displayed with a colored (and anti-aliased) border around their shape. FT_Stroker \u00b6 Defined in FT_STROKER_H (freetype/ftstroke.h). typedef struct FT_StrokerRec_* FT_Stroker ; Opaque handle to a path stroker object. FT_Stroker_LineJoin \u00b6 Defined in FT_STROKER_H (freetype/ftstroke.h). typedef enum FT_Stroker_LineJoin_ { FT_STROKER_LINEJOIN_ROUND = 0, FT_STROKER_LINEJOIN_BEVEL = 1, FT_STROKER_LINEJOIN_MITER_VARIABLE = 2, FT_STROKER_LINEJOIN_MITER = FT_STROKER_LINEJOIN_MITER_VARIABLE , FT_STROKER_LINEJOIN_MITER_FIXED = 3 } FT_Stroker_LineJoin ; These values determine how two joining lines are rendered in a stroker. values FT_STROKER_LINEJOIN_ROUND Used to render rounded line joins. Circular arcs are used to join two lines smoothly. FT_STROKER_LINEJOIN_BEVEL Used to render beveled line joins. The outer corner of the joined lines is filled by enclosing the triangular region of the corner with a straight line between the outer corners of each stroke. FT_STROKER_LINEJOIN_MITER_FIXED Used to render mitered line joins, with fixed bevels if the miter limit is exceeded. The outer edges of the strokes for the two segments are extended until they meet at an angle. A bevel join (see above) is used if the segments meet at too sharp an angle and the outer edges meet beyond a distance corresponding to the meter limit. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter line join as used in PostScript and PDF. FT_STROKER_LINEJOIN_MITER_VARIABLE FT_STROKER_LINEJOIN_MITER Used to render mitered line joins, with variable bevels if the miter limit is exceeded. The intersection of the strokes is clipped perpendicularly to the bisector, at a distance corresponding to the miter limit. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line join as used in XPS. FT_STROKER_LINEJOIN_MITER is an alias for FT_STROKER_LINEJOIN_MITER_VARIABLE , retained for backward compatibility.

FT_STROKER_LINECAP_ROUND The end of lines is rendered as a half-circle around the last point. FT_STROKER_LINECAP_SQUARE The end of lines is rendered as a square around the last point.

FT_STROKER_BORDER_RIGHT Select the right border, relative to the drawing direction. note Applications are generally interested in the \u2018inside\u2019 and \u2018outside\u2019 borders. However, there is no direct mapping between these and the \u2018left\u2019 and \u2018right\u2019 ones, since this really depends on the glyph's drawing orientation, which varies between font formats. You can however use FT_Outline_GetInsideBorder and FT_Outline_GetOutsideBorder to get these. FT_Outline_GetInsideBorder \u00b6 Defined in FT_STROKER_H (freetype/ftstroke.h).

They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters. Unicode maintains two different sets, namely \u2018Standardized Variation Sequences\u2019 and registered \u2018Ideographic Variation Sequences\u2019 (IVS), collected in the \u2018Ideographic Variation Database\u2019 (IVD). https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt https://unicode.org/reports/tr37/ https://unicode.org/ivd/ To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS. Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only. A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence U+9089 U+E0100 . Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font. A variation may be either \u2018default\u2019 or \u2018non-default\u2019 for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.

They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters. Unicode maintains two different sets, namely \u2018Standardized Variation Sequences\u2019 and registered \u2018Ideographic Variation Sequences\u2019 (IVS), collected in the \u2018Ideographic Variation Database\u2019 (IVD). https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt https://unicode.org/reports/tr37/ https://unicode.org/ivd/ To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS. Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only. A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence U+9089 U+E0100 . Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font. A variation may be either \u2018default\u2019 or \u2018non-default\u2019 for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap.

This is a mode where all glyphs loaded from a given FT_Face are provided by the client application. Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor. To enable this mode, you must use FT_Open_Face , passing an FT_Parameter with the FT_PARAM_TAG_INCREMENTAL tag and an FT_Incremental_Interface value. See the comments for FT_Incremental_InterfaceRec for an example. FT_Incremental \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_IncrementalRec_* FT_Incremental ; An opaque type describing a user-provided object used to implement \u2018incremental\u2019 glyph loading within FreeType. This is used to support embedded fonts in certain environments (e.g., PostScript interpreters), where the glyph data isn't in the font file, or must be overridden by different values. note It is up to client applications to create and implement FT_Incremental objects, as long as they provide implementations for the methods FT_Incremental_GetGlyphDataFunc , FT_Incremental_FreeGlyphDataFunc and FT_Incremental_GetGlyphMetricsFunc . See the description of FT_Incremental_InterfaceRec to understand how to use incremental objects with FreeType. FT_Incremental_MetricsRec \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_Incremental_MetricsRec_ { FT_Long bearing_x; FT_Long bearing_y; FT_Long advance; FT_Long advance_v; /* since 2.3.12 */ } FT_Incremental_MetricsRec ; A small structure used to contain the basic glyph metrics returned by the FT_Incremental_GetGlyphMetricsFunc method. fields bearing_x Left bearing, in font units. bearing_y Top bearing, in font units. advance Horizontal component of glyph advance, in font units. advance_v Vertical component of glyph advance, in font units. note These correspond to horizontal or vertical metrics depending on the value of the vertical argument to the function FT_Incremental_GetGlyphMetricsFunc . FT_Incremental_Metrics \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_Incremental_MetricsRec_* FT_Incremental_Metrics ; A handle to an FT_Incremental_MetricsRec structure. FT_Incremental_GetGlyphDataFunc \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef FT_Error (* FT_Incremental_GetGlyphDataFunc )( FT_Incremental incremental, FT_UInt glyph_index, FT_Data * adata ); A function called by FreeType to access a given glyph's data bytes during FT_Load_Glyph or FT_Load_Char if incremental loading is enabled. Note that the format of the glyph's data bytes depends on the font file format. For TrueType, it must correspond to the raw bytes within the \u2018glyf\u2019 table. For PostScript formats, it must correspond to the unencrypted charstring bytes, without any lenIV header. It is undefined for any other format. input incremental Handle to an opaque FT_Incremental handle provided by the client application. glyph_index Index of relevant glyph. output adata A structure describing the returned glyph data bytes (which will be accessed as a read-only byte block). return FreeType error code. 0 means success. note If this function returns successfully the method FT_Incremental_FreeGlyphDataFunc will be called later to release the data bytes. Nested calls to FT_Incremental_GetGlyphDataFunc can happen for compound glyphs. FT_Incremental_FreeGlyphDataFunc \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef void (* FT_Incremental_FreeGlyphDataFunc )( FT_Incremental incremental, FT_Data * data ); A function used to release the glyph data bytes returned by a successful call to FT_Incremental_GetGlyphDataFunc . input incremental A handle to an opaque FT_Incremental handle provided by the client application. data A structure describing the glyph data bytes (which will be accessed as a read-only byte block). FT_Incremental_GetGlyphMetricsFunc \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef FT_Error (* FT_Incremental_GetGlyphMetricsFunc ) ( FT_Incremental incremental, FT_UInt glyph_index, FT_Bool vertical, FT_Incremental_MetricsRec *ametrics ); A function used to retrieve the basic metrics of a given glyph index before accessing its data. This allows for handling font types such as PCL XL Format 1, Class 2 downloaded TrueType fonts, where the glyph metrics ( hmtx and vmtx tables) are permitted to be omitted from the font, and the relevant metrics included in the header of the glyph outline data. Importantly, this is not intended to allow custom glyph metrics (for example, Postscript Metrics dictionaries), because that conflicts with the requirements of outline hinting. Such custom metrics must be handled separately, by the calling application. input incremental A handle to an opaque FT_Incremental handle provided by the client application. glyph_index Index of relevant glyph. vertical If true, return vertical metrics. ametrics This parameter is used for both input and output. The original glyph metrics, if any, in font units. If metrics are not available all the values must be set to zero. output ametrics The glyph metrics in font units. FT_Incremental_FuncsRec \u00b6 Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). typedef struct FT_Incremental_FuncsRec_ { FT_Incremental_GetGlyphDataFunc get_glyph_data; FT_Incremental_FreeGlyphDataFunc free_glyph_data; FT_Incremental_GetGlyphMetricsFunc get_glyph_metrics; } FT_Incremental_FuncsRec ; A table of functions for accessing fonts that load data incrementally. Used in FT_Incremental_InterfaceRec . fields get_glyph_data The function to get glyph data. Must not be null. free_glyph_data The function to release glyph data.

Docs \u00bb Core API \u00bb Information Retrieval Information Retrieval \u00b6 Synopsis \u00b6 Functions to retrieve font and glyph information. Only some very basic data is covered; see also the chapter on the format-specific API for more. FT_Get_Name_Index \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_UInt ) FT_Get_Name_Index ( FT_Face face, const FT_String * glyph_name ); Return the glyph index of a given glyph name. This only works for those faces where FT_HAS_GLYPH_NAMES returns true. input face A handle to the source face object. glyph_name The glyph name. return The glyph index. 0 means \u2018undefined character code\u2019. note Acceptable glyph names might come from the Adobe Glyph List . See FT_Get_Glyph_Name for the inverse functionality. This function has limited capabilities if the config macro FT_CONFIG_OPTION_POSTSCRIPT_NAMES is not defined in ftoption.h : It then works only for fonts that actually embed glyph names (which many recent OpenType fonts do not). FT_Get_Glyph_Name \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Get_Glyph_Name ( FT_Face face, FT_UInt glyph_index, FT_Pointer buffer, FT_UInt buffer_max ); Retrieve the ASCII name of a given glyph in a face. This only works for those faces where FT_HAS_GLYPH_NAMES returns true. input face A handle to a source face object. glyph_index The glyph index. buffer_max The maximum number of bytes available in the buffer. output buffer A pointer to a target buffer where the name is copied to. return FreeType error code. 0 means success. note An error is returned if the face doesn't provide glyph names or if the glyph index is invalid. In all cases of failure, the first byte of buffer is set to 0 to indicate an empty name. The glyph name is truncated to fit within the buffer if it is too long. The returned string is always zero-terminated. Be aware that FreeType reorders glyph indices internally so that glyph index 0 always corresponds to the \u2018missing glyph\u2019 (called \u2018.notdef\u2019). This function has limited capabilities if the config macro FT_CONFIG_OPTION_POSTSCRIPT_NAMES is not defined in ftoption.h : It then works only for fonts that actually embed glyph names (which many recent OpenType fonts do not). FT_Get_Postscript_Name \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( const char * ) FT_Get_Postscript_Name ( FT_Face face ); Retrieve the ASCII PostScript name of a given face, if available. This only works with PostScript, TrueType, and OpenType fonts. input face A handle to the source face object. return A pointer to the face's PostScript name. NULL if unavailable. note The returned pointer is owned by the face and is destroyed with it. For variation fonts, this string changes if you select a different instance, and you have to call FT_Get_PostScript_Name again to retrieve it. FreeType follows Adobe TechNote #5902, \u2018Generating PostScript Names for Fonts Using OpenType Font Variations\u2019. https://download.macromedia.com/pub/developer/opentype/tech-notes/5902.AdobePSNameGeneration.html [Since 2.9] Special PostScript names for named instances are only returned if the named instance is set with FT_Set_Named_Instance (and the font has corresponding entries in its \u2018fvar\u2019 table or is the default named instance).

FT_EXPORT( FT_Bool ) FT_Get_Color_Glyph_Layer ( FT_Face face, FT_UInt base_glyph, FT_UInt *aglyph_index, FT_UInt *acolor_index, FT_LayerIterator * iterator ); This is an interface to the \u2018COLR\u2019 table in OpenType fonts to iteratively retrieve the colored glyph layers associated with the current glyph slot. https://docs.microsoft.com/en-us/typography/opentype/spec/colr The glyph layer data for a given glyph index, if present, provides an alternative, multi-color glyph representation: Instead of rendering the outline or bitmap with the given glyph index, glyphs with the indices and colors returned by this function are rendered layer by layer. The returned elements are ordered in the z direction from bottom to top; the 'n'th element should be rendered with the associated palette color and blended on top of the already rendered layers (elements 0, 1, \u2026, n-1). input face A handle to the parent face object. base_glyph The glyph index the colored glyph layers are associated with. inout iterator An FT_LayerIterator object. For the first call you should set iterator->p to NULL . For all following calls, simply use the same object again. output aglyph_index The glyph index of the current layer. acolor_index The color index into the font face's color palette of the current layer. The value 0xFFFF is special; it doesn't reference a palette entry but indicates that the text foreground color should be used instead (to be set up by the application outside of FreeType). The color palette can be retrieved with FT_Palette_Select . return Value 1 if everything is OK. If there are no more layers (or if there are no layers at all), value 0 gets returned. In case of an error, value 0 is returned also. note This function is necessary if you want to handle glyph layers by yourself. In particular, functions that operate with FT_GlyphRec objects (like FT_Get_Glyph or FT_Glyph_To_Bitmap ) don't have access to this information.

FT_EXPORT( FT_Bool ) FT_Get_Color_Glyph_Paint ( FT_Face face, FT_UInt base_glyph, FT_Color_Root_Transform root_transform, FT_OpaquePaint * paint ); This is the starting point and interface to color gradient information in a \u2018COLR\u2019 v1 table in OpenType fonts to recursively retrieve the paint tables for the directed acyclic graph of a colored glyph, given a glyph ID. https://github.com/googlefonts/colr-gradients-spec In a \u2018COLR\u2019 v1 font, each color glyph defines a directed acyclic graph of nested paint tables, such as PaintGlyph , PaintSolid , PaintLinearGradient , PaintRadialGradient , and so on. Using this function and specifying a glyph ID, one retrieves the root paint table for this glyph ID. This function allows control whether an initial root transform is returned to configure scaling, transform, and translation correctly on the client's graphics context. The initial root transform is computed and returned according to the values configured for FT_Size and FT_Set_Transform on the FT_Face object, see below for details of the root_transform parameter. This has implications for a client \u2018COLR\u2019 v1 implementation: When this function returns an initially computed root transform, at the time of executing the FT_PaintGlyph operation, the contours should be retrieved using FT_Load_Glyph at unscaled, untransformed size. This is because the root transform applied to the graphics context will take care of correct scaling. Alternatively, to allow hinting of contours, at the time of executing FT_Load_Glyph , the current graphics context transformation matrix can be decomposed into a scaling matrix and a remainder, and FT_Load_Glyph can be used to retrieve the contours at scaled size. Care must then be taken to blit or clip to the graphics context with taking this remainder transformation into account. input face A handle to the parent face object. base_glyph The glyph index for which to retrieve the root paint table. root_transform Specifies whether an initially computed root is returned by the FT_PaintTransform operation to account for the activated size (see FT_Activate_Size ) and the configured transform and translate (see FT_Set_Transform ). This root transform is returned before nodes of the glyph graph of the font are returned. Subsequent FT_COLR_Paint structures contain unscaled and untransformed values. The inserted root transform enables the client application to apply an initial transform to its graphics context. When executing subsequent FT_COLR_Paint operations, values from FT_COLR_Paint operations will ultimately be correctly scaled because of the root transform applied to the graphics context. Use FT_COLOR_INCLUDE_ROOT_TRANSFORM to include the root transform, use FT_COLOR_NO_ROOT_TRANSFORM to not include it. The latter may be useful when traversing the \u2018COLR\u2019 v1 glyph graph and reaching a FT_PaintColrGlyph . When recursing into FT_PaintColrGlyph and painting that inline, no additional root transform is needed as it has already been applied to the graphics context at the beginning of drawing this glyph. output paint The FT_OpaquePaint object that references the actual paint table. The respective actual FT_COLR_Paint object is retrieved via FT_Get_Paint . return Value 1 if everything is OK. If no color glyph is found, or the root paint could not be retrieved, value 0 gets returned.

If the root paint of a color glyph, or a nested paint of a \u2018COLR\u2019 glyph is a PaintColrLayers table, this function retrieves the layers of the PaintColrLayers table. The FT_PaintColrLayers object contains an FT_LayerIterator , which is used here to iterate over the layers.

Should you define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ftoption.h file, this enables ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise. ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of 3. Using the subpixel coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed evenly. Therefore, an equalizing 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties: It should be symmetrical, like { a, b, c, b, a }, to avoid any shifts in appearance. It should be color-balanced, meaning a + b = c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally. It should be normalized, meaning 2a + 2b + c = 1.0 to maintain overall brightness. Boxy 3-tap filter {0, \u2153, \u2153, \u2153, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant. Use the FT_Library_SetLcdFilter or FT_Library_SetLcdFilterWeights API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through FT_Render_Glyph . Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel can be rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage. The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-\u2153, 0}, {0, 0}, {\u2153, 0}} for standard RGB striped panel or {{-\u2159, \u00bc}, {-\u2159, -\u00bc}, {\u2153, 0}} for a certain PenTile panel. Use the FT_Library_SetLcdGeometry API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter. As a result of ClearType filtering or Harmony shifts, the resulting dimensions of LCD bitmaps can be slightly wider or taller than the dimensions the original outline with regard to the pixel grid. For example, for FT_RENDER_MODE_LCD , the filter adds 2 subpixels to the left, and 2 subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter. The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through FT_Render_Glyph , FT_Load_Glyph , FT_Load_Char , and FT_Glyph_To_Bitmap , when FT_RENDER_MODE_LCD or FT_RENDER_MODE_LCD_V is specified. This API does not control FT_Outline_Render and FT_Outline_Get_Bitmap . The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space.

FT_EXPORT( FT_Error ) FT_New_Library ( FT_Memory memory, FT_Library *alibrary ); This function is used to create a new FreeType library instance from a given memory object. It is thus possible to use libraries with distinct memory allocators within the same program. Note, however, that the used FT_Memory structure is expected to remain valid for the life of the FT_Library object. Normally, you would call this function (followed by a call to FT_Add_Default_Modules or a series of calls to FT_Add_Module , and a call to FT_Set_Default_Properties ) instead of FT_Init_FreeType to initialize the FreeType library. Don't use FT_Done_FreeType but FT_Done_Library to destroy a library instance. input memory A handle to the original memory object. output alibrary A pointer to handle of a new library object. return FreeType error code. 0 means success. note See the discussion of reference counters in the description of FT_Reference_Library . FT_Done_Library \u00b6 Defined in FT_MODULE_H (freetype/ftmodapi.h). FT_EXPORT( FT_Error ) FT_Done_Library ( FT_Library library ); Discard a given library object.

FT_Reference_Library \u00b6 Defined in FT_MODULE_H (freetype/ftmodapi.h). FT_EXPORT( FT_Error ) FT_Reference_Library ( FT_Library library ); A counter gets initialized to 1 at the time an FT_Library structure is created. This function increments the counter. FT_Done_Library then only destroys a library if the counter is 1, otherwise it simply decrements the counter. This function helps in managing life-cycles of structures that reference FT_Library objects. input library A handle to a target library object. return FreeType error code. 0 means success. since 2.4.2 FT_Renderer \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_RendererRec_* FT_Renderer ; A handle to a given FreeType renderer. A renderer is a module in charge of converting a glyph's outline image to a bitmap. It supports a single glyph image format, and one or more target surface depths.

This is a pointer to its raster's class. FT_Get_Renderer \u00b6 Defined in FT_RENDER_H (freetype/ftrender.h). FT_EXPORT( FT_Renderer ) FT_Get_Renderer ( FT_Library library, FT_Glyph_Format format ); Retrieve the current renderer for a given glyph format. input library A handle to the library object. format The glyph format. return A renderer handle. 0 if none found. note An error will be returned if a module already exists by that name, or if the module requires a version of FreeType that is too great. To add a new renderer, simply use FT_Add_Module . To retrieve a renderer by its name, use FT_Get_Module . FT_Set_Renderer \u00b6 Defined in FT_RENDER_H (freetype/ftrender.h). FT_EXPORT( FT_Error ) FT_Set_Renderer ( FT_Library library, FT_Renderer renderer, FT_UInt num_params, FT_Parameter * parameters ); Set the current renderer to use, and set additional mode. inout library A handle to the library object. input renderer A handle to the renderer object. num_params The number of additional parameters. parameters Additional parameters. return FreeType error code. 0 means success. note In case of success, the renderer will be used to convert glyph images in the renderer's known format into bitmaps. This doesn't change the current renderer for other formats. Currently, no FreeType renderer module uses parameters ; you should thus always pass NULL as the value.

Have a look at the source code of the ttdebug FreeType demo program for an example of its usage. inout library A handle to the library object. input hook_index The index of the debug hook. You should use defined enumeration macros like FT_DEBUG_HOOK_TRUETYPE . debug_hook The function used to debug the interpreter. note Currently, four debug hook slots are available, but only one (for the TrueType interpreter) is defined. FT_Driver \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_DriverRec_* FT_Driver ; A handle to a given FreeType font driver object. A font driver is a module capable of creating faces from font files.

Its job is essentially to activate debug mode to enforce single-stepping, to call the main loop function to interpret the next opcode, and to show the changed context to the user. An example for such a main loop function is TT_RunIns (declared in FreeType's internal header file src/truetype/ttinterp.h ). Have a look at the source code of the ttdebug FreeType demo program for an example of a drop-in replacement. inout arg A typeless pointer, to be cast to the main loop function's data structure (which depends on the font module).

If it is larger than the number of designs, the extra values are ignored. If it is less than the number of designs, the remaining values are set to zero. weightvector An array representing the weight vector. return FreeType error code. 0 means success. note Adobe Multiple Master fonts limit the number of designs, and thus the length of the weight vector to 16 elements. If len is larger than zero, this function sets the FT_FACE_FLAG_VARIATION bit in FT_Face 's face_flags field (i.e., FT_IS_VARIATION will return true). If len is zero, this bit flag is unset and the weight vector array is reset to the default values.

This function can't be used with TrueType GX or OpenType variation fonts. inout face A handle to the source face. len A pointer to the size of the array to be filled. If the size of the array is less than the number of designs, FT_Err_Invalid_Argument is returned, and len is set to the required size (the number of designs). If the size of the array is greater than the number of designs, the remaining entries are set to 0. On successful completion, len is set to the number of designs (i.e., the number of values written to the array). output weightvector An array to be filled. return FreeType error code. 0 means success. note Adobe Multiple Master fonts limit the number of designs, and thus the length of the WeightVector to 16. since 2.10 FT_VAR_AXIS_FLAG_XXX \u00b6 Defined in FT_MULTIPLE_MASTERS_H (freetype/ftmm.h). # define FT_VAR_AXIS_FLAG_HIDDEN 1 A list of bit flags used in the return value of FT_Get_Var_Axis_Flags . values FT_VAR_AXIS_FLAG_HIDDEN The variation axis should not be exposed to user interfaces. since 2.8.1 FT_Get_Var_Axis_Flags \u00b6 Defined in FT_MULTIPLE_MASTERS_H (freetype/ftmm.h).

FT_Outline \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Outline_ { short n_contours; /* number of contours in glyph */ short n_points; /* number of points in the glyph */ FT_Vector * points; /* the outline's points */ char * tags; /* the points flags */ short * contours; /* the contour end points */ int flags; /* outline masks */ } FT_Outline ; This structure is used to describe an outline to the scan-line converter. fields n_contours The number of contours in the outline. n_points The number of points in the outline. points A pointer to an array of n_points FT_Vector elements, giving the outline's point coordinates. tags A pointer to an array of n_points chars, giving each outline point's type. If bit 0 is unset, the point is \u2018off\u2019 the curve, i.e., a Bezier control point, while it is \u2018on\u2019 if set. Bit 1 is meaningful for \u2018off\u2019 points only. If set, it indicates a third-order Bezier arc control point; and a second-order control point if unset. If bit 2 is set, bits 5-7 contain the drop-out mode (as defined in the OpenType specification; the value is the same as the argument to the \u2018SCANMODE\u2019 instruction). Bits 3 and 4 are reserved for internal purposes. contours An array of n_contours shorts, giving the end point of each contour within the outline. For example, the first contour is defined by the points \u20180\u2019 to contours[0] , the second one is defined by the points contours[0]+1 to contours[1] , etc. flags A set of bit flags used to characterize the outline and give hints to the scan-converter and hinter on how to convert/grid-fit it. See FT_OUTLINE_XXX . note The B/W rasterizer only checks bit 2 in the tags array for the first point of each contour. The drop-out mode as given with FT_OUTLINE_IGNORE_DROPOUTS , FT_OUTLINE_SMART_DROPOUTS , and FT_OUTLINE_INCLUDE_STUBS in flags is then overridden. FT_Outline_New \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_New ( FT_Library library, FT_UInt numPoints, FT_Int numContours, FT_Outline *anoutline ); Create a new outline of a given size. input library A handle to the library object from where the outline is allocated. Note however that the new outline will not necessarily be freed , when destroying the library, by FT_Done_FreeType . numPoints The maximum number of points within the outline. Must be smaller than or equal to 0xFFFF (65535). numContours The maximum number of contours within the outline. This value must be in the range 0 to numPoints . output anoutline A handle to the new outline. return FreeType error code. 0 means success. note The reason why this function takes a library parameter is simply to use the library's memory allocator. FT_Outline_Done \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Done ( FT_Library library, FT_Outline * outline ); Destroy an outline created with FT_Outline_New . input library A handle of the library object used to allocate the outline. outline A pointer to the outline object to be discarded. return FreeType error code. 0 means success. note If the outline's \u2018owner\u2019 field is not set, only the outline descriptor will be released. FT_Outline_Copy \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Copy ( const FT_Outline * source, FT_Outline *target ); Copy an outline into another one. Both objects must have the same sizes (number of points & number of contours) when this function is called. input source A handle to the source outline. output target A handle to the target outline. return FreeType error code. 0 means success. FT_Outline_Translate \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Translate ( const FT_Outline * outline, FT_Pos xOffset, FT_Pos yOffset ); Apply a simple translation to the points of an outline. inout outline A pointer to the target outline descriptor. input xOffset The horizontal offset. yOffset The vertical offset. FT_Outline_Transform \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Transform ( const FT_Outline * outline, const FT_Matrix * matrix ); Apply a simple 2x2 matrix to all of an outline's points. Useful for applying rotations, slanting, flipping, etc. inout outline A pointer to the target outline descriptor. input matrix A pointer to the transformation matrix. note You can use FT_Outline_Translate if you need to translate the outline's points. FT_Outline_Embolden \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Embolden ( FT_Outline * outline, FT_Pos strength ); Embolden an outline. The new outline will be at most 4 times strength pixels wider and higher. You may think of the left and bottom borders as unchanged. Negative strength values to reduce the outline thickness are possible also. inout outline A handle to the target outline. input strength How strong the glyph is emboldened. Expressed in 26.6 pixel format. return FreeType error code. 0 means success. note The used algorithm to increase or decrease the thickness of the glyph doesn't change the number of points; this means that certain situations like acute angles or intersections are sometimes handled incorrectly. If you need \u2018better\u2019 metrics values you should call FT_Outline_Get_CBox or FT_Outline_Get_BBox . To get meaningful results, font scaling values must be set with functions like FT_Set_Char_Size before calling FT_Render_Glyph. example FT_Load_Glyph( face, index, FT_LOAD_DEFAULT ); if ( face->glyph->format == FT_GLYPH_FORMAT_OUTLINE ) FT_Outline_Embolden( &face->glyph->outline, strength ); FT_Outline_EmboldenXY \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_EmboldenXY ( FT_Outline * outline, FT_Pos xstrength, FT_Pos ystrength ); Embolden an outline. The new outline will be xstrength pixels wider and ystrength pixels higher. Otherwise, it is similar to FT_Outline_Embolden , which uses the same strength in both directions. since 2.4.10 FT_Outline_Reverse \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Reverse ( FT_Outline * outline ); Reverse the drawing direction of an outline. This is used to ensure consistent fill conventions for mirrored glyphs. inout outline A pointer to the target outline descriptor. note This function toggles the bit flag FT_OUTLINE_REVERSE_FILL in the outline's flags field. It shouldn't be used by a normal client application, unless it knows what it is doing. FT_Outline_Check \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Check ( FT_Outline * outline ); Check the contents of an outline descriptor. input outline A handle to a source outline. return FreeType error code. 0 means success. note An empty outline, or an outline with a single point only is also valid. FT_Outline_Get_CBox \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( void ) FT_Outline_Get_CBox ( const FT_Outline * outline, FT_BBox *acbox ); Return an outline's \u2018control box\u2019. The control box encloses all the outline's points, including Bezier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline that contains Bezier outside arcs). Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the \u2018ftbbox\u2019 component, which is dedicated to this single task. input outline A pointer to the source outline descriptor. output acbox The outline's control box. note See FT_Glyph_Get_CBox for a discussion of tricky fonts. FT_Outline_Get_BBox \u00b6 Defined in FT_BBOX_H (freetype/ftbbox.h). FT_EXPORT( FT_Error ) FT_Outline_Get_BBox ( FT_Outline * outline, FT_BBox *abbox ); Compute the exact bounding box of an outline. This is slower than computing the control box. However, it uses an advanced algorithm that returns very quickly when the two boxes coincide. Otherwise, the outline Bezier arcs are traversed to extract their extrema. input outline A pointer to the source outline. output abbox The outline's exact bounding box. return FreeType error code. 0 means success. note If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE , the resulting BBox is meaningless. To get reasonable values for the BBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the BBox, which can be eventually converted back to font units. FT_Outline_Get_Bitmap \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Get_Bitmap ( FT_Library library, FT_Outline * outline, const FT_Bitmap *abitmap ); Render an outline within a bitmap. The outline's image is simply OR-ed to the target bitmap. input library A handle to a FreeType library object. outline A pointer to the source outline descriptor. inout abitmap A pointer to the target bitmap descriptor. return FreeType error code. 0 means success. note This function does not create the bitmap, it only renders an outline image within the one you pass to it! Consequently, the various fields in abitmap should be set accordingly. It will use the raster corresponding to the default glyph format. The value of the num_grays field in abitmap is ignored. If you select the gray-level rasterizer, and you want less than 256 gray levels, you have to use FT_Outline_Render directly. FT_Outline_Render \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Render ( FT_Library library, FT_Outline * outline, FT_Raster_Params * params ); Render an outline within a bitmap using the current scan-convert. input library A handle to a FreeType library object. outline A pointer to the source outline descriptor. inout params A pointer to an FT_Raster_Params structure used to describe the rendering operation. return FreeType error code. 0 means success. note This advanced function uses FT_Raster_Params as an argument. The field params.source will be set to outline before the scan converter is called, which means that the value you give to it is actually ignored. Either params.target must point to preallocated bitmap, or FT_RASTER_FLAG_DIRECT must be set in params.flags allowing FreeType rasterizer to be used for direct composition, translucency, etc. See FT_Raster_Params for more details. FT_Outline_Decompose \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Error ) FT_Outline_Decompose ( FT_Outline * outline, const FT_Outline_Funcs * func_interface, void * user ); Walk over an outline's structure to decompose it into individual segments and Bezier arcs. This function also emits \u2018move to\u2019 operations to indicate the start of new contours in the outline. input outline A pointer to the source target. func_interface A table of \u2018emitters\u2019, i.e., function pointers called during decomposition to indicate path operations. inout user A typeless pointer that is passed to each emitter during the decomposition. It can be used to store the state during the decomposition. return FreeType error code. 0 means success. note Degenerate contours, segments, and Bezier arcs may be reported. In most cases, it is best to filter these out before using the outline for stroking or other path modification purposes (which may cause degenerate segments to become non-degenrate and visible, like when stroke caps are used or the path is otherwise outset). Some glyph outlines may contain deliberate degenerate single points for mark attachement. Similarly, the function returns success for an empty outline also (doing nothing, that is, not calling any emitter); if necessary, you should filter this out, too. FT_Outline_Funcs \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Outline_Funcs_ { FT_Outline_MoveToFunc move_to; FT_Outline_LineToFunc line_to; FT_Outline_ConicToFunc conic_to; FT_Outline_CubicToFunc cubic_to; int shift; FT_Pos delta; } FT_Outline_Funcs ; A structure to hold various function pointers used during outline decomposition in order to emit segments, conic, and cubic Beziers. fields move_to The \u2018move to\u2019 emitter. line_to The segment emitter. conic_to The second-order Bezier arc emitter. cubic_to The third-order Bezier arc emitter. shift The shift that is applied to coordinates before they are sent to the emitter. delta The delta that is applied to coordinates before they are sent to the emitter, but after the shift. note The point coordinates sent to the emitters are the transformed version of the original coordinates (this is important for high accuracy during scan-conversion). The transformation is simple: x' = (x << shift) - delta y' = (y << shift) - delta Set the values of shift and delta to 0 to get the original point coordinates. FT_Outline_MoveToFunc \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef int (* FT_Outline_MoveToFunc )( const FT_Vector * to, void * user ); # define FT_Outline_MoveTo_Func FT_Outline_MoveToFunc A function pointer type used to describe the signature of a \u2018move to\u2019 function during outline walking/decomposition. A \u2018move to\u2019 is emitted to start a new contour in an outline. input to A pointer to the target point of the \u2018move to\u2019. user A typeless pointer, which is passed from the caller of the decomposition function. return Error code. 0 means success. FT_Outline_LineToFunc \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef int (* FT_Outline_LineToFunc )( const FT_Vector * to, void * user ); # define FT_Outline_LineTo_Func FT_Outline_LineToFunc A function pointer type used to describe the signature of a \u2018line to\u2019 function during outline walking/decomposition. A \u2018line to\u2019 is emitted to indicate a segment in the outline. input to A pointer to the target point of the \u2018line to\u2019. user A typeless pointer, which is passed from the caller of the decomposition function. return Error code. 0 means success. FT_Outline_ConicToFunc \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef int (* FT_Outline_ConicToFunc )( const FT_Vector * control, const FT_Vector * to, void * user ); # define FT_Outline_ConicTo_Func FT_Outline_ConicToFunc A function pointer type used to describe the signature of a \u2018conic to\u2019 function during outline walking or decomposition. A \u2018conic to\u2019 is emitted to indicate a second-order Bezier arc in the outline. input control An intermediate control point between the last position and the new target in to . to A pointer to the target end point of the conic arc. user A typeless pointer, which is passed from the caller of the decomposition function. return Error code. 0 means success. FT_Outline_CubicToFunc \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef int (* FT_Outline_CubicToFunc )( const FT_Vector * control1, const FT_Vector * control2, const FT_Vector * to, void * user ); # define FT_Outline_CubicTo_Func FT_Outline_CubicToFunc A function pointer type used to describe the signature of a \u2018cubic to\u2019 function during outline walking or decomposition. A \u2018cubic to\u2019 is emitted to indicate a third-order Bezier arc. input control1 A pointer to the first Bezier control point. control2 A pointer to the second Bezier control point. to A pointer to the target end point. user A typeless pointer, which is passed from the caller of the decomposition function. return Error code. 0 means success. FT_Orientation \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). typedef enum FT_Orientation_ { FT_ORIENTATION_TRUETYPE = 0, FT_ORIENTATION_POSTSCRIPT = 1, FT_ORIENTATION_FILL_RIGHT = FT_ORIENTATION_TRUETYPE , FT_ORIENTATION_FILL_LEFT = FT_ORIENTATION_POSTSCRIPT , FT_ORIENTATION_NONE } FT_Orientation ; A list of values used to describe an outline's contour orientation. The TrueType and PostScript specifications use different conventions to determine whether outline contours should be filled or unfilled. values FT_ORIENTATION_TRUETYPE According to the TrueType specification, clockwise contours must be filled, and counter-clockwise ones must be unfilled. FT_ORIENTATION_POSTSCRIPT According to the PostScript specification, counter-clockwise contours must be filled, and clockwise ones must be unfilled. FT_ORIENTATION_FILL_RIGHT This is identical to FT_ORIENTATION_TRUETYPE , but is used to remember that in TrueType, everything that is to the right of the drawing direction of a contour must be filled. FT_ORIENTATION_FILL_LEFT This is identical to FT_ORIENTATION_POSTSCRIPT , but is used to remember that in PostScript, everything that is to the left of the drawing direction of a contour must be filled. FT_ORIENTATION_NONE The orientation cannot be determined. That is, different parts of the glyph have different orientation. FT_Outline_Get_Orientation \u00b6 Defined in FT_OUTLINE_H (freetype/ftoutln.h). FT_EXPORT( FT_Orientation ) FT_Outline_Get_Orientation ( FT_Outline * outline ); This function analyzes a glyph outline and tries to compute its fill orientation (see FT_Orientation ). This is done by integrating the total area covered by the outline. The positive integral corresponds to the clockwise orientation and FT_ORIENTATION_POSTSCRIPT is returned. The negative integral corresponds to the counter-clockwise orientation and FT_ORIENTATION_TRUETYPE is returned. Note that this will return FT_ORIENTATION_TRUETYPE for empty outlines. input outline A handle to the source outline. return The orientation.

FT_OUTLINE_OWNER If set, this flag indicates that the outline's field arrays (i.e., points , flags , and contours ) are \u2018owned\u2019 by the outline object, and should thus be freed when it is destroyed. FT_OUTLINE_EVEN_ODD_FILL By default, outlines are filled using the non-zero winding rule. If set to 1, the outline will be filled using the even-odd fill rule (only works with the smooth rasterizer). FT_OUTLINE_REVERSE_FILL By default, outside contours of an outline are oriented in clock-wise direction, as defined in the TrueType specification. This flag is set if the outline uses the opposite direction (typically for Type 1 fonts). This flag is ignored by the scan converter. FT_OUTLINE_IGNORE_DROPOUTS By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information. FT_OUTLINE_SMART_DROPOUTS Select smart dropout control. If unset, use simple dropout control. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information. FT_OUTLINE_INCLUDE_STUBS If set, turn pixels on for \u2018stubs\u2019, otherwise exclude them. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information. FT_OUTLINE_OVERLAP [Since 2.10.3] This flag indicates that this outline contains overlapping contours and the anti-aliased renderer should perform oversampling to mitigate possible artifacts. This flag should not be set for well designed glyphs without overlaps because it quadruples the rendering time. FT_OUTLINE_HIGH_PRECISION This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter. FT_OUTLINE_SINGLE_PASS This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image. Normally, it is set for very large character sizes. It is only a hint that might be completely ignored by a given scan-converter. note The flags FT_OUTLINE_IGNORE_DROPOUTS , FT_OUTLINE_SMART_DROPOUTS , and FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer. There exists a second mechanism to pass the drop-out mode to the B/W rasterizer; see the tags field in FT_Outline . Please refer to the description of the \u2018SCANTYPE\u2019 instruction in the OpenType specification (in file ttinst1.doc ) how simple drop-outs, smart drop-outs, and stubs are defined.","title":"Outline Processing"},{"location":"ft2-outline_processing.html#outline-processing","text":"","title":"Outline Processing"},{"location":"ft2-outline_processing.html#synopsis","text":"This section contains routines used to create and destroy scalable glyph images known as \u2018outlines\u2019.

FT_HINTING_ADOBE Use the hinting engine contributed by Adobe. since 2.9 hinting-engine \u00b6 Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between \u2018freetype\u2019 and \u2018adobe\u2019 if compiled with CFF_CONFIG_OPTION_OLD_ENGINE . If this configuration macro isn't defined, \u2018hinting-engine\u2019 does nothing. The same holds for the Type 1 and CID modules if compiled with T1_CONFIG_OPTION_OLD_ENGINE . For the \u2018cff\u2019 module, the default engine is \u2018adobe\u2019. For both the \u2018type1\u2019 and \u2018t1cid\u2019 modules, the default engine is \u2018adobe\u2019, too. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values \u2018adobe\u2019 or \u2018freetype\u2019). example The following example code demonstrates how to select Adobe's hinting engine for the \u2018cff\u2019 module (omitting the error handling). FT_Library library; FT_UInt hinting_engine = FT_HINTING_ADOBE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"cff\", \"hinting-engine\", &hinting_engine ); since 2.4.12 (for \u2018cff\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) no-stem-darkening \u00b6 All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type 1, and CID font modules if the \u2018Adobe\u2019 engine is selected (which is the default). Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see FT_Render_Glyph . When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy! Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs \u2018thin out\u2019. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore \u2018blacker\u2019. This counteracts the \u2018thinning out\u2019 of glyphs, making text remain readable at smaller sizes. For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (that is, no-stem-darkening is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver. Note that stem darkening is never applied if FT_LOAD_NO_SCALE is set. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values 1 and 0 for \u2018on\u2019 and \u2018off\u2019, respectively). It can also be set per face using FT_Face_Properties with FT_PARAM_TAG_STEM_DARKENING . example FT_Library library; FT_Bool no_stem_darkening = TRUE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"cff\", \"no-stem-darkening\", &no_stem_darkening ); since 2.4.12 (for \u2018cff\u2019 module) 2.6.2 (for \u2018autofitter\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) darkening-parameters \u00b6 By default, the Adobe hinting engine, as used by the CFF, Type 1, and CID font drivers, darkens stems as follows (if the no-stem-darkening property isn't set): stem width <= 0.5px: darkening amount = 0.4px stem width = 1px: darkening amount = 0.275px stem width = 1.667px: darkening amount = 0.275px stem width >= 2.333px: darkening amount = 0px and piecewise linear in-between. At configuration time, these four control points can be set with the macro CFF_CONFIG_OPTION_DARKENING_PARAMETERS ; the CFF, Type 1, and CID drivers share these values. At runtime, the control points can be changed using the darkening-parameters property (see the example below that demonstrates this for the Type 1 driver). The x values give the stem width, and the y values the darkening amount. The unit is 1000 th of pixels. All coordinate values must be positive; the x values must be monotonically increasing; the y values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4). The auto-hinter provides this property, too, as an experimental feature. See no-stem-darkening for more. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable, using eight comma-separated integers without spaces. Here the above example, using \\ to break the line for readability. FREETYPE_PROPERTIES=\\ type1:darkening-parameters=500,300,1000,200,1500,100,2000,0 example FT_Library library; FT_Int darken_params[8] = { 500, 300, // x1, y1 1000, 200, // x2, y2 1500, 100, // x3, y3 2000, 0 }; // x4, y4 FT_Init_FreeType( &library ); FT_Property_Set( library, \"type1\", \"darkening-parameters\", darken_params ); since 2.5.1 (for \u2018cff\u2019 module) 2.6.2 (for \u2018autofitter\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) random-seed \u00b6 By default, the seed value for the CFF \u2018random\u2019 operator and the similar \u20180 28 callothersubr pop\u2019 command for the Type 1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by \u2018random\u2019 are repeatable. The random-seed property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the intitialRandomSeed private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of initialRandomSeed , which is consequently ignored. note This property can be set via the FREETYPE_PROPERTIES environment variable. It can also be set per face using FT_Face_Properties with FT_PARAM_TAG_RANDOM_SEED . since 2.8 (for \u2018cff\u2019 module) 2.9 (for \u2018type1\u2019 and \u2018t1cid\u2019 modules) no-long-family-names \u00b6 If PCF_CONFIG_OPTION_LONG_FAMILY_NAMES is active while compiling FreeType, the PCF driver constructs long family names. There are many PCF fonts just called \u2018Fixed\u2019 which look completely different, and which have nothing to do with each other. When selecting \u2018Fixed\u2019 in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name. It also checks whether there are \u2018wide\u2019 characters; all put together, family names like \u2018Sony Fixed\u2019 or \u2018Misc Fixed Wide\u2019 are constructed. If no-long-family-names is set, this feature gets switched off. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values 1 and 0 for \u2018on\u2019 and \u2018off\u2019, respectively). example FT_Library library; FT_Bool no_long_family_names = TRUE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"pcf\", \"no-long-family-names\", &no_long_family_names ); since 2.8 TT_INTERPRETER_VERSION_XXX \u00b6 Defined in FT_DRIVER_H (freetype/ftdriver.h). # define TT_INTERPRETER_VERSION_35 35 # define TT_INTERPRETER_VERSION_38 38 # define TT_INTERPRETER_VERSION_40 40 A list of constants used for the interpreter-version property to select the hinting engine for Truetype fonts. The numeric value in the constant names represents the version number as returned by the \u2018GETINFO\u2019 bytecode instruction. values TT_INTERPRETER_VERSION_35 Version 35 corresponds to MS rasterizer v.1.7 as used e.g. in Windows 98; only grayscale and B/W rasterizing is supported. TT_INTERPRETER_VERSION_38 Version 38 is the same Version 40. The original \u2018Infinality\u2019 code is no longer available. TT_INTERPRETER_VERSION_40 Version 40 corresponds to MS rasterizer v.2.1; it is roughly equivalent to the hinting provided by DirectWrite ClearType (as can be found, for example, in Microsoft's Edge Browser on Windows 10). It is used in FreeType to select the \u2018minimal\u2019 subpixel hinting code, a stripped-down and higher performance version of the \u2018Infinality\u2019 code. note This property controls the behaviour of the bytecode interpreter and thus how outlines get hinted. It does not control how glyph get rasterized! In particular, it does not control subpixel color filtering. If FreeType has not been compiled with the configuration option TT_CONFIG_OPTION_SUBPIXEL_HINTING , selecting version 38 or 40 causes an FT_Err_Unimplemented_Feature error. Depending on the graphics framework, Microsoft uses different bytecode and rendering engines. As a consequence, the version numbers returned by a call to the \u2018GETINFO\u2019 bytecode instruction are more convoluted than desired. Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it. GETINFO framework version feature ------------------------------------------------------------------- 3 GDI (Win 3.1), v1.0 16-bit, first version TrueImage 33 GDI (Win NT 3.1), v1.5 32-bit HP Laserjet 34 GDI (Win 95) v1.6 font smoothing, new SCANTYPE opcode 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET bits in composite glyphs 36 MGDI (Win CE 2) v1.6+ classic ClearType 37 GDI (XP and later), v1.8 ClearType GDI+ old (before Vista) 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType, WPF Y-direction ClearType, additional error checking 39 DWrite (before Win 8) v2.0 subpixel ClearType flags in GETINFO opcode, bug fixes 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag DWrite (Win 8) in GETINFO opcode, Gray ClearType The \u2018version\u2019 field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support. version sampling rendering comment x y x y -------------------------------------------------------------- v1.0 normal normal B/W B/W bi-level v1.6 high high gray gray grayscale v1.8 high normal color-filter B/W (GDI) ClearType v1.9 high high color-filter gray Color ClearType v2.1 high normal gray B/W Gray ClearType v2.1 high high gray gray Gray ClearType Color and Gray ClearType are the two available variants of \u2018Y-direction ClearType\u2019, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is \u2018symmetric smoothing\u2019. \u2018Classic ClearType\u2019 is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is \u2018font smoothing\u2019, and \u2018Color ClearType\u2019 is sometimes also called \u2018DWrite ClearType\u2019. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called \u2018GDI ClearType\u2019. \u2018Normal\u2019 and \u2018high\u2019 sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. \u2018Normal\u2019 means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, \u2018high\u2019 means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like \u2018MIRP\u2019. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated. Note that \u2018Gray ClearType\u2019 is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1). Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals. interpreter-version \u00b6 Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old \u2018Infinality\u2019 code and new stripped-down and higher performance \u2018minimal\u2019 code) and one without, respectively. The default is subpixel support if TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support otherwise (since it isn't available then). If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if \u2018native ClearType\u2019 is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter. Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at \u2018 https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx \u2019. Note that FreeType currently doesn't really \u2018subpixel hint\u2019 (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results. note This property can be used with FT_Property_Get also. This property can be set via the FREETYPE_PROPERTIES environment variable (using values \u201835\u2019, \u201838\u2019, or \u201840\u2019). example The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling). FT_Library library; FT_Face face; FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35; FT_Init_FreeType( &library ); FT_Property_Set( library, \"truetype\", \"interpreter-version\", &interpreter_version ); since 2.5 svg-hooks \u00b6 Set up the interface between FreeType and an extern SVG rendering library like \u2018librsvg\u2019. All details on the function hooks can be found in section \u2018 OpenType SVG Fonts \u2019. example The following example code expects that the four hook functions svg_* are defined elsewhere. Error handling is omitted, too. FT_Library library; SVG_RendererHooks hooks = { (SVG_Lib_Init_Func)svg_init, (SVG_Lib_Free_Func)svg_free, (SVG_Lib_Render_Func)svg_render, (SVG_Lib_Preset_Slot_Func)svg_preset_slot }; FT_Init_FreeType( &library ); FT_Property_Set( library, \"ot-svg\", \"svg-hooks\", &hooks ); since 2.12 glyph-to-script-map \u00b6 Experimental only The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below. OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called \u2018features\u2019. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType. The mapping between glyph indices and scripts (in the auto-hinter sense, see the FT_AUTOHINTER_SCRIPT_XXX values) is stored as an array with num_glyphs elements, as found in the font's FT_Face structure. The glyph-to-script-map property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping. example The following example code demonstrates how to access it (omitting the error handling). FT_Library library; FT_Face face; FT_Prop_GlyphToScriptMap prop; FT_Init_FreeType( &library ); FT_New_Face( library, \"foo.ttf\", 0, &face ); prop.face = face; FT_Property_Get( library, \"autofitter\", \"glyph-to-script-map\", &prop ); // adjust `prop.map' as needed right here FT_Load_Glyph( face, ..., FT_LOAD_FORCE_AUTOHINT ); since 2.4.11 FT_AUTOHINTER_SCRIPT_XXX \u00b6 Defined in FT_DRIVER_H (freetype/ftdriver.h). # define FT_AUTOHINTER_SCRIPT_NONE 0 # define FT_AUTOHINTER_SCRIPT_LATIN 1 # define FT_AUTOHINTER_SCRIPT_CJK 2 # define FT_AUTOHINTER_SCRIPT_INDIC 3 Experimental only A list of constants used for the glyph-to-script-map property to specify the script submodule the auto-hinter should use for hinting a particular glyph. values FT_AUTOHINTER_SCRIPT_NONE Don't auto-hint this glyph.

By default, this is FT_AUTOHINTER_SCRIPT_CJK . Using the fallback-script property, this fallback value can be changed. note This property can be used with FT_Property_Get also. It's important to use the right timing for changing this value: The creation of the glyph-to-script map that eventually uses the fallback script value gets triggered either by setting or reading a face-specific property like glyph-to-script-map , or by auto-hinting any glyph from that face. In particular, if you have already created an FT_Face structure but not loaded any glyph (using the auto-hinter), a change of the fallback script will affect this face. example FT_Library library; FT_UInt fallback_script = FT_AUTOHINTER_SCRIPT_NONE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"autofitter\", \"fallback-script\", &fallback_script ); since 2.4.11 default-script \u00b6 Experimental only If FreeType gets compiled with FT_CONFIG_OPTION_USE_HARFBUZZ to make the HarfBuzz library access OpenType features for getting better glyph coverages, this property sets the (auto-fitter) script to be used for the default (OpenType) script data of a font's GSUB table. Features for the default script are intended for all scripts not explicitly handled in GSUB; an example is a \u2018dlig\u2019 feature, containing the combination of the characters \u2018T\u2019, \u2018E\u2019, and \u2018L\u2019 to form a \u2018TEL\u2019 ligature. By default, this is FT_AUTOHINTER_SCRIPT_LATIN . Using the default-script property, this default value can be changed. note This property can be used with FT_Property_Get also. It's important to use the right timing for changing this value: The creation of the glyph-to-script map that eventually uses the default script value gets triggered either by setting or reading a face-specific property like glyph-to-script-map , or by auto-hinting any glyph from that face. In particular, if you have already created an FT_Face structure but not loaded any glyph (using the auto-hinter), a change of the default script will affect this face. example FT_Library library; FT_UInt default_script = FT_AUTOHINTER_SCRIPT_NONE; FT_Init_FreeType( &library ); FT_Property_Set( library, \"autofitter\", \"default-script\", &default_script ); since 2.5.3 increase-x-height \u00b6 For ppem values in the range 6 <= ppem <= increase-x-height , round up the font's x height much more often than normally. If the value is set to 0, which is the default, this feature is switched off. Use this property to improve the legibility of small font sizes if necessary. note This property can be used with FT_Property_Get also. Set this value right after calling FT_Set_Char_Size , but before loading any glyph (using the auto-hinter). example FT_Library library; FT_Face face; FT_Prop_IncreaseXHeight prop; FT_Init_FreeType( &library ); FT_New_Face( library, \"foo.ttf\", 0, &face ); FT_Set_Char_Size( face, 10 * 64, 0, 72, 0 ); prop.face = face; prop.limit = 14; FT_Property_Set( library, \"autofitter\", \"increase-x-height\", &prop ); since 2.4.11 FT_Prop_IncreaseXHeight \u00b6 Defined in FT_DRIVER_H (freetype/ftdriver.h). typedef struct FT_Prop_IncreaseXHeight_ { FT_Face face; FT_UInt limit; } FT_Prop_IncreaseXHeight ; The data exchange structure for the increase-x-height property. warping \u00b6 Obsolete This property was always experimental and probably never worked correctly. It was entirely removed from the FreeType 2 sources. This entry is only here for historical reference. Warping only worked in \u2018normal\u2019 auto-hinting mode replacing it. The idea of the code was to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments were aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations were tried and scored. since 2.6","title":"Driver properties"},{"location":"ft2-properties.html#driver-properties","text":"","title":"Driver properties"},{"location":"ft2-properties.html#synopsis","text":"Driver modules can be controlled by setting and unsetting properties, using the functions FT_Property_Set and FT_Property_Get .

The same is true for the CFF, Type 1, and CID font modules if the \u2018Adobe\u2019 engine is selected (which is the default). Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see FT_Render_Glyph . When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy! Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs \u2018thin out\u2019. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore \u2018blacker\u2019. This counteracts the \u2018thinning out\u2019 of glyphs, making text remain readable at smaller sizes. For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (that is, no-stem-darkening is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones.

The mapping between glyph indices and scripts (in the auto-hinter sense, see the FT_AUTOHINTER_SCRIPT_XXX values) is stored as an array with num_glyphs elements, as found in the font's FT_Face structure. The glyph-to-script-map property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.","title":"glyph-to-script-map"},{"location":"ft2-properties.html#ft_autohinter_script_xxx","text":"Defined in FT_DRIVER_H (freetype/ftdriver.h). # define FT_AUTOHINTER_SCRIPT_NONE 0 # define FT_AUTOHINTER_SCRIPT_LATIN 1 # define FT_AUTOHINTER_SCRIPT_CJK 2 # define FT_AUTOHINTER_SCRIPT_INDIC 3 Experimental only A list of constants used for the glyph-to-script-map property to specify the script submodule the auto-hinter should use for hinting a particular glyph.","title":"FT_AUTOHINTER_SCRIPT_XXX"},{"location":"ft2-properties.html#ft_prop_glyphtoscriptmap","text":"Defined in FT_DRIVER_H (freetype/ftdriver.h). typedef struct FT_Prop_GlyphToScriptMap_ { FT_Face face; FT_UShort * map; } FT_Prop_GlyphToScriptMap ; Experimental only The data exchange structure for the glyph-to-script-map property.","title":"FT_Prop_GlyphToScriptMap"},{"location":"ft2-properties.html#fallback-script","text":"Experimental only If no auto-hinter script module can be assigned to a glyph, a fallback script gets assigned to it (see also the glyph-to-script-map property).

FreeType comes with two rasterizers: bilevel raster1 and anti-aliased smooth are two separate modules. They are usually called from the high-level FT_Load_Glyph or FT_Render_Glyph functions and produce the entire coverage bitmap at once, while staying largely invisible to users. Instead of working with complete coverage bitmaps, it is also possible to intercept consecutive pixel runs on the same scanline with the same coverage, called spans , and process them individually. Only the smooth rasterizer permits this when calling FT_Outline_Render with FT_Raster_Params as described below. Working with either complete bitmaps or spans it is important to think of them as colorless coverage objects suitable as alpha channels to blend arbitrary colors with a background. For best results, it is recommended to use gamma correction, too. This section also describes the public API needed to set up alternative FT_Renderer modules. FT_Span \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Span_ { short x; unsigned short len; unsigned char coverage; } FT_Span ; A structure to model a single span of consecutive pixels when rendering an anti-aliased bitmap. fields x The span's horizontal start position. len The span's length in pixels. coverage The span color/coverage, ranging from 0 (background) to 255 (foreground). note This structure is used by the span drawing callback type named FT_SpanFunc that takes the y coordinate of the span as a parameter. The anti-aliased rasterizer produces coverage values from 0 to 255, that is, from completely transparent to completely opaque. FT_SpanFunc \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef void (* FT_SpanFunc )( int y, int count, const FT_Span * spans, void * user ); # define FT_Raster_Span_Func FT_SpanFunc A function used as a call-back by the anti-aliased renderer in order to let client applications draw themselves the pixel spans on each scan line. input y The scanline's upward y coordinate. count The number of spans to draw on this scanline. spans A table of count spans to draw on the scanline. user User-supplied data that is passed to the callback. note This callback allows client applications to directly render the spans of the anti-aliased bitmap to any kind of surfaces. This can be used to write anti-aliased outlines directly to a given background bitmap using alpha compositing. It can also be used for oversampling and averaging. FT_Raster_Params \u00b6 Defined in FT_IMAGE_H (freetype/ftimage.h). typedef struct FT_Raster_Params_ { const FT_Bitmap * target; const void * source; int flags; FT_SpanFunc gray_spans; FT_SpanFunc black_spans; /* unused */ FT_Raster_BitTest_Func bit_test; /* unused */ FT_Raster_BitSet_Func bit_set; /* unused */ void * user; FT_BBox clip_box; } FT_Raster_Params ; A structure to hold the parameters used by a raster's render function, passed as an argument to FT_Outline_Render . fields target The target bitmap. source A pointer to the source glyph image (e.g., an FT_Outline ). flags The rendering flags. gray_spans The gray span drawing callback. black_spans Unused. bit_test Unused. bit_set Unused. user User-supplied data that is passed to each drawing callback. clip_box An optional span clipping box expressed in integer pixels (not in 26.6 fixed-point units). note The FT_RASTER_FLAG_AA bit flag must be set in the flags to generate an anti-aliased glyph bitmap, otherwise a monochrome bitmap is generated. The target should have appropriate pixel mode and its dimensions define the clipping region. If both FT_RASTER_FLAG_AA and FT_RASTER_FLAG_DIRECT bit flags are set in flags , the raster calls an FT_SpanFunc callback gray_spans with user data as an argument ignoring target . This allows direct composition over a pre-existing user surface to perform the span drawing and composition. To optionally clip the spans, set the FT_RASTER_FLAG_CLIP flag and clip_box . The monochrome raster does not support the direct mode. The gray-level rasterizer always uses 256 gray levels. If you want fewer gray levels, you have to use FT_RASTER_FLAG_DIRECT and reduce the levels in the callback function.

FT_RASTER_FLAG_DIRECT This flag is set to indicate direct rendering. In this mode, client applications must provide their own span callback. This lets them directly draw or compose over an existing bitmap. If this bit is not set, the target pixmap's buffer must be zeroed before rendering and the output will be clipped to its size. Direct rendering is only possible with anti-aliased glyphs. FT_RASTER_FLAG_CLIP This flag is only used in direct rendering mode. If set, the output will be clipped to a box specified in the clip_box field of the FT_Raster_Params structure. Otherwise, the clip_box is effectively set to the bounding box and all spans are generated.

FT_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_SizeRec_* FT_Size ; A handle to an object that models a face scaled to a given character size. note An FT_Face has one active FT_Size object that is used by functions like FT_Load_Glyph to determine the scaling transformation that in turn is used to load and hint glyphs and metrics. A newly created FT_Size object contains only meaningless zero values. You must use FT_Set_Char_Size , FT_Set_Pixel_Sizes , FT_Request_Size or even FT_Select_Size to change the content (i.e., the scaling values) of the active FT_Size . Otherwise, the scaling and hinting will not be performed. You can use FT_New_Size to create additional size objects for a given FT_Face , but they won't be used by other functions until you activate it through FT_Activate_Size . Only one size can be activated at any given time per face. also See FT_SizeRec for the publicly accessible fields of a given size object. FT_SizeRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_SizeRec_ { FT_Face face; /* parent face object */ FT_Generic generic; /* generic pointer for client uses */ FT_Size_Metrics metrics; /* size metrics */ FT_Size_Internal internal; } FT_SizeRec ; FreeType root size class structure. A size object models a face object at a given size. fields face Handle to the parent face object. generic A typeless pointer, unused by the FreeType library or any of its drivers. It can be used by client applications to link their own data to each size object. metrics Metrics for this size object. This field is read-only. FT_Size_Metrics \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_Metrics_ { FT_UShort x_ppem; /* horizontal pixels per EM */ FT_UShort y_ppem; /* vertical pixels per EM */ FT_Fixed x_scale; /* scaling values used to convert font */ FT_Fixed y_scale; /* units to 26.6 fractional pixels */ FT_Pos ascender; /* ascender in 26.6 frac. pixels */ FT_Pos descender; /* descender in 26.6 frac. pixels */ FT_Pos height; /* text height in 26.6 frac. pixels */ FT_Pos max_advance; /* max horizontal advance, in 26.6 pixels */ } FT_Size_Metrics ; The size metrics structure gives the metrics of a size object. fields x_ppem The width of the scaled EM square in pixels, hence the term \u2018ppem\u2019 (pixels per EM). It is also referred to as \u2018nominal width\u2019. y_ppem The height of the scaled EM square in pixels, hence the term \u2018ppem\u2019 (pixels per EM). It is also referred to as \u2018nominal height\u2019. x_scale A 16.16 fractional scaling value to convert horizontal metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats. y_scale A 16.16 fractional scaling value to convert vertical metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats. ascender The ascender in 26.6 fractional pixels, rounded up to an integer value. See FT_FaceRec for the details. descender The descender in 26.6 fractional pixels, rounded down to an integer value. See FT_FaceRec for the details. height The height in 26.6 fractional pixels, rounded to an integer value. See FT_FaceRec for the details. max_advance The maximum advance width in 26.6 fractional pixels, rounded to an integer value. See FT_FaceRec for the details. note The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in FT_FaceRec . Some values like ascender or descender are rounded for historical reasons; more precise values (for outline fonts) can be derived by scaling the corresponding FT_FaceRec values manually, with code similar to the following. scaled_ascender = FT_MulFix( face->ascender, size_metrics->y_scale ); Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel! Indeed, the only way to get the exact metrics is to render all glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations. The FT_Size_Metrics structure is valid for bitmap fonts also. TrueType fonts with native bytecode hinting All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions. The application has to cater for this, especially if it wants to rely on a TTF's vertical data (for example, to properly align box characters vertically). Only the application knows in advance that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an FT_Size object but much later, namely while calling FT_Load_Glyph . Here is some pseudo code that illustrates a possible solution. font_format = FT_Get_Font_Format( face ); if ( !strcmp( font_format, \"TrueType\" ) && do_native_bytecode_hinting ) { ascender = ROUND( FT_MulFix( face->ascender, size_metrics->y_scale ) ); descender = ROUND( FT_MulFix( face->descender, size_metrics->y_scale ) ); } else { ascender = size_metrics->ascender; descender = size_metrics->descender; } height = size_metrics->height; max_advance = size_metrics->max_advance; FT_Bitmap_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Bitmap_Size_ { FT_Short height; FT_Short width; FT_Pos size; FT_Pos x_ppem; FT_Pos y_ppem; } FT_Bitmap_Size ; This structure models the metrics of a bitmap strike (i.e., a set of glyphs for a given point size and resolution) in a bitmap font. It is used for the available_sizes field of FT_Face . fields height The vertical distance, in pixels, between two consecutive baselines. It is always positive. width The average width, in pixels, of all glyphs in the strike. size The nominal size of the strike in 26.6 fractional points. This field is not very useful. x_ppem The horizontal ppem (nominal width) in 26.6 fractional pixels. y_ppem The vertical ppem (nominal height) in 26.6 fractional pixels. note Windows FNT: The nominal size given in a FNT font is not reliable. If the driver finds it incorrect, it sets size to some calculated values, and x_ppem and y_ppem to the pixel width and height given in the font, respectively. TrueType embedded bitmaps: size , width , and height values are not contained in the bitmap strike itself. They are computed from the global font parameters. FT_Set_Char_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Char_Size ( FT_Face face, FT_F26Dot6 char_width, FT_F26Dot6 char_height, FT_UInt horz_resolution, FT_UInt vert_resolution ); Call FT_Request_Size to request the nominal size (in points). inout face A handle to a target face object. input char_width The nominal width, in 26.6 fractional points. char_height The nominal height, in 26.6 fractional points. horz_resolution The horizontal resolution in dpi. vert_resolution The vertical resolution in dpi. return FreeType error code. 0 means success. note While this function allows fractional points as input values, the resulting ppem value for the given resolution is always rounded to the nearest integer. If either the character width or height is zero, it is set equal to the other value. If either the horizontal or vertical resolution is zero, it is set equal to the other value. A character width or height smaller than 1pt is set to 1pt; if both resolution values are zero, they are set to 72dpi. Don't use this function if you are using the FreeType cache API. FT_Set_Pixel_Sizes \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Set_Pixel_Sizes ( FT_Face face, FT_UInt pixel_width, FT_UInt pixel_height ); Call FT_Request_Size to request the nominal size (in pixels). inout face A handle to the target face object. input pixel_width The nominal width, in pixels. pixel_height The nominal height, in pixels. return FreeType error code. 0 means success. note You should not rely on the resulting glyphs matching or being constrained to this pixel size. Refer to FT_Request_Size to understand how requested sizes relate to actual sizes. Don't use this function if you are using the FreeType cache API. FT_Request_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Request_Size ( FT_Face face, FT_Size_Request req ); Resize the scale of the active FT_Size object in a face. inout face A handle to a target face object. input req A pointer to a FT_Size_RequestRec . return FreeType error code. 0 means success. note Although drivers may select the bitmap strike matching the request, you should not rely on this if you intend to select a particular bitmap strike. Use FT_Select_Size instead in that case. The relation between the requested size and the resulting glyph size is dependent entirely on how the size is defined in the source face. The font designer chooses the final size of each glyph relative to this size. For more information refer to \u2018 https://www.freetype.org/freetype2/docs/glyphs/glyphs-2.html \u2019. Contrary to FT_Set_Char_Size , this function doesn't have special code to normalize zero-valued widths, heights, or resolutions, which are treated as FT_LOAD_NO_SCALE . Don't use this function if you are using the FreeType cache API. FT_Select_Size \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). FT_EXPORT( FT_Error ) FT_Select_Size ( FT_Face face, FT_Int strike_index ); Select a bitmap strike. To be more precise, this function sets the scaling factors of the active FT_Size object in a face so that bitmaps from this particular strike are taken by FT_Load_Glyph and friends. inout face A handle to a target face object. input strike_index The index of the bitmap strike in the available_sizes field of FT_FaceRec structure. return FreeType error code. 0 means success. note For bitmaps embedded in outline fonts it is common that only a subset of the available glyphs at a given ppem value is available. FreeType silently uses outlines if there is no bitmap for a given glyph index. For GX and OpenType variation fonts, a bitmap strike makes sense only if the default instance is active (that is, no glyph variation takes place); otherwise, FreeType simply ignores bitmap strikes. The same is true for all named instances that are different from the default instance. Don't use this function if you are using the FreeType cache API. FT_Size_Request_Type \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef enum FT_Size_Request_Type_ { FT_SIZE_REQUEST_TYPE_NOMINAL , FT_SIZE_REQUEST_TYPE_REAL_DIM , FT_SIZE_REQUEST_TYPE_BBOX , FT_SIZE_REQUEST_TYPE_CELL , FT_SIZE_REQUEST_TYPE_SCALES , FT_SIZE_REQUEST_TYPE_MAX } FT_Size_Request_Type ; An enumeration type that lists the supported size request types, i.e., what input size (in font units) maps to the requested output size (in pixels, as computed from the arguments of FT_Size_Request ). values FT_SIZE_REQUEST_TYPE_NOMINAL The nominal size. The units_per_EM field of FT_FaceRec is used to determine both scaling values. This is the standard scaling found in most applications. In particular, use this size request type for TrueType fonts if they provide optical scaling or something similar. Note, however, that units_per_EM is a rather abstract value which bears no relation to the actual size of the glyphs in a font. FT_SIZE_REQUEST_TYPE_REAL_DIM The real dimension. The sum of the ascender and (minus of) the descender fields of FT_FaceRec is used to determine both scaling values. FT_SIZE_REQUEST_TYPE_BBOX The font bounding box. The width and height of the bbox field of FT_FaceRec are used to determine the horizontal and vertical scaling value, respectively. FT_SIZE_REQUEST_TYPE_CELL The max_advance_width field of FT_FaceRec is used to determine the horizontal scaling value; the vertical scaling value is determined the same way as FT_SIZE_REQUEST_TYPE_REAL_DIM does. Finally, both scaling values are set to the smaller one. This type is useful if you want to specify the font size for, say, a window of a given dimension and 80x24 cells. FT_SIZE_REQUEST_TYPE_SCALES Specify the scaling values directly. note The above descriptions only apply to scalable formats. For bitmap formats, the behaviour is up to the driver. See the note section of FT_Size_Metrics if you wonder how size requesting relates to scaling values. FT_Size_RequestRec \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_RequestRec_ { FT_Size_Request_Type type; FT_Long width; FT_Long height; FT_UInt horiResolution; FT_UInt vertResolution; } FT_Size_RequestRec ; A structure to model a size request. fields type See FT_Size_Request_Type . width The desired width, given as a 26.6 fractional point value (with 72pt = 1in). height The desired height, given as a 26.6 fractional point value (with 72pt = 1in). horiResolution The horizontal resolution (dpi, i.e., pixels per inch). If set to zero, width is treated as a 26.6 fractional pixel value, which gets internally rounded to an integer. vertResolution The vertical resolution (dpi, i.e., pixels per inch). If set to zero, height is treated as a 26.6 fractional pixel value, which gets internally rounded to an integer. note If width is zero, the horizontal scaling value is set equal to the vertical scaling value, and vice versa. If type is FT_SIZE_REQUEST_TYPE_SCALES , width and height are interpreted directly as 16.16 fractional scaling values, without any further modification, and both horiResolution and vertResolution are ignored. FT_Size_Request \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h). typedef struct FT_Size_RequestRec_ * FT_Size_Request ; A handle to a size request structure. FT_Set_Transform \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h).

Use NULL for the identity matrix. delta A pointer to the translation vector. Use NULL for the null vector. note This function is provided as a convenience, but keep in mind that FT_Matrix coefficients are only 16.16 fixed-point values, which can limit the accuracy of the results. Using floating-point computations to perform the transform directly in client code instead will always yield better numbers. The transformation is only applied to scalable image formats after the glyph has been loaded. It means that hinting is unaltered by the transformation and is performed on the character size given in the last call to FT_Set_Char_Size or FT_Set_Pixel_Sizes . Note that this also transforms the face.glyph.advance field, but not the values in face.glyph.metrics . FT_Get_Transform \u00b6 Defined in FT_FREETYPE_H (freetype/freetype.h).

When it is the former, the argument cache is set to FALSE . When it is the latter, the argument cache is set to TRUE . This distinction has been made because many calculations that are necessary for presetting a glyph slot are the same needed later for the render callback hook. Thus, if cache is TRUE , the hook can cache those calculations in a memory block referenced by the state pointer. This hook is expected to preset the slot by setting parameters such as bitmap_left , bitmap_top , width , rows , pitch , and pixel_mode . It is also expected to set all the metrics for the slot including the vertical advance if it is not already set. Typically, fonts have horizontal advances but not vertical ones. If those are available, they had already been set, otherwise they have to be estimated and set manually. The hook must take into account the transformations that have been set, and translate the transformation matrices into the SVG coordinate system, as the original matrix is intended for the TTF/CFF coordinate system. input slot The glyph slot that has the SVG document loaded. cache See description. inout data_pointer The SVG rendering module stores a pointer variable that can be used by clients to store any data that needs to be shared across different hooks. data_pointer is essentially a pointer to that pointer such that it can be written to as well as read from. return FreeType error code. 0 means success. since 2.12 SVG_RendererHooks \u00b6 Defined in FT_OTSVG_H (freetype/otsvg.h). typedef struct SVG_RendererHooks_ { SVG_Lib_Init_Func init_svg; SVG_Lib_Free_Func free_svg; SVG_Lib_Render_Func render_svg; SVG_Lib_Preset_Slot_Func preset_slot; } SVG_RendererHooks ; A structure that stores the four hooks needed to render OT-SVG glyphs properly. The structure is publicly used to set the hooks via the svg-hooks driver property. The behavior of each hook is described in its documentation. One thing to note is that the preset hook and the render hook often need to do the same operations; therefore, it's better to cache the intermediate data in a state structure to avoid calculating it twice. For example, in the preset hook one can draw the glyph on a recorder surface and later create a bitmap surface from it in the render hook.

FT_EXPORT( void * ) FT_Get_Sfnt_Table ( FT_Face face, FT_Sfnt_Tag tag ); Return a pointer to a given SFNT table stored within a face. input face A handle to the source. tag The index of the SFNT table. return A type-less pointer to the table. This will be NULL in case of error, or if the corresponding table was not found OR loaded from the file. Use a typecast according to tag to access the structure elements. note The table is owned by the face object and disappears with it. This function is only useful to access SFNT tables that are loaded by the sfnt, truetype, and opentype drivers. See FT_Sfnt_Tag for a list. example Here is an example demonstrating access to the \u2018vhea\u2019 table. TT_VertHeader* vert_header; vert_header = (TT_VertHeader*)FT_Get_Sfnt_Table( face, FT_SFNT_VHEA ); FT_Load_Sfnt_Table \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Error ) FT_Load_Sfnt_Table ( FT_Face face, FT_ULong tag, FT_Long offset, FT_Byte * buffer, FT_ULong * length ); Load any SFNT font table into client memory. input face A handle to the source face. tag The four-byte tag of the table to load. Use value 0 if you want to access the whole font file. Otherwise, you can use one of the definitions found in the FT_TRUETYPE_TAGS_H file, or forge a new one with FT_MAKE_TAG . offset The starting offset in the table (or file if tag == 0). output buffer The target buffer address. The client must ensure that the memory array is big enough to hold the data. inout length If the length parameter is NULL , try to load the whole table. Return an error code if it fails. Else, if *length is 0, exit immediately while returning the table's (or file) full size in it. Else the number of bytes to read from the table or file, from the starting offset. return FreeType error code. 0 means success. note If you need to determine the table's length you should first call this function with *length set to 0, as in the following example: FT_ULong length = 0; error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length ); if ( error ) { ... table does not exist ... } buffer = malloc( length ); if ( buffer == NULL ) { ... not enough memory ... } error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length ); if ( error ) { ... could not load table ... } Note that structures like TT_Header or TT_OS2 can't be used with this function; they are limited to FT_Get_Sfnt_Table . Reason is that those structures depend on the processor architecture, with varying size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian). FT_Sfnt_Table_Info \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Error ) FT_Sfnt_Table_Info ( FT_Face face, FT_UInt table_index, FT_ULong *tag, FT_ULong *length ); Return information on an SFNT table. input face A handle to the source face. table_index The index of an SFNT table. The function returns FT_Err_Table_Missing for an invalid value. inout tag The name tag of the SFNT table. If the value is NULL , table_index is ignored, and length returns the number of SFNT tables in the font. output length The length of the SFNT table (or the number of SFNT tables, depending on tag ). return FreeType error code. 0 means success. note While parsing fonts, FreeType handles SFNT tables with length zero as missing. FT_Get_CMap_Language_ID \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_ULong ) FT_Get_CMap_Language_ID ( FT_CharMap charmap ); Return cmap language ID as specified in the OpenType standard. Definitions of language ID values are in file FT_TRUETYPE_IDS_H . input charmap The target charmap. return The language ID of charmap . If charmap doesn't belong to an SFNT face, just return 0 as the default value. For a format 14 cmap (to access Unicode IVS), the return value is 0xFFFFFFFF. FT_Get_CMap_Format \u00b6 Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h). FT_EXPORT( FT_Long ) FT_Get_CMap_Format ( FT_CharMap charmap ); Return the format of an SFNT \u2018cmap\u2019 table. input charmap The target charmap. return The format of charmap .

The TrueType driver's module name is \u2018truetype\u2019; a single property interpreter-version is available, as documented in the \u2018 Driver properties \u2019 section. To help understand the differences between interpreter versions, we introduce a list of definitions, kindly provided by Greg Hitchcock. Bi-Level Rendering Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, \u2018hdmx\u2019 and \u2018LTSH\u2019, to cache hinting widths across multiple sizes and device aspect ratios. Font Smoothing Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering. ClearType Rendering Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls \u2018natural widths\u2019 ClearType, see http://rastertragedy.com/RTRCh4.htm#Sec21 . Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode. ClearType Compatible Widths One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see http://rastertragedy.com/RTRCh4.htm#Sec20 . Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths. ClearType Subpixel Positioning One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this \u2018natural mode\u2019, not to be confused with GDI's \u2018natural widths\u2019. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see http://rastertragedy.com/RTRCh4.htm#Sec22 . Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes. ClearType Backward Compatibility This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see http://rastertragedy.com/RTRCh4.htm#Sec1 and https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx .

FT_EXPORT( FT_Int ) FT_Has_PS_Glyph_Names ( FT_Face face ); Return true if a given face provides reliable PostScript glyph names. This is similar to using the FT_HAS_GLYPH_NAMES macro, except that certain fonts (mostly TrueType) contain incorrect glyph name tables. When this function returns true, the caller is sure that the glyph names returned by FT_Get_Glyph_Name are reliable. input face face handle return Boolean. True if glyph names are reliable.

Missing entries in the font's FontInfo dictionary are represented by NULL pointers. The following font formats support this feature: \u2018Type 1\u2019, \u2018Type 42\u2019, \u2018CFF\u2019, \u2018CID Type 1\u2019.

FT_Get_PS_Font_Value \u00b6 Defined in FT_TYPE1_TABLES_H (freetype/t1tables.h). FT_EXPORT( FT_Long ) FT_Get_PS_Font_Value ( FT_Face face, PS_Dict_Keys key, FT_UInt idx, void *value, FT_Long value_len ); Retrieve the value for the supplied key from a PostScript font. input face PostScript face handle. key An enumeration value representing the dictionary key to retrieve. idx For array values, this specifies the index to be returned. value A pointer to memory into which to write the value. valen_len The size, in bytes, of the memory supplied for the value. output value The value matching the above key, if it exists. return The amount of memory (in bytes) required to hold the requested value (if it exists, -1 otherwise). note The values returned are not pointers into the internal structures of the face, but are \u2018fresh\u2019 copies, so that the memory containing them belongs to the calling application. This also enforces the \u2018read-only\u2019 nature of these values, i.e., this function cannot be used to manipulate the face. value is a void pointer because the values returned can be of various types. If either value is NULL or value_len is too small, just the required memory size for the requested entry is returned. The idx parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values. PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale). IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either. If the font's format is not PostScript-based, this function returns the FT_Err_Invalid_Argument error code. since 2.4.8 T1_Blend_Flags \u00b6 Defined in FT_TYPE1_TABLES_H (freetype/t1tables.h). typedef enum T1_Blend_Flags_ { /* required fields in a FontInfo blend dictionary */ T1_BLEND_UNDERLINE_POSITION = 0, T1_BLEND_UNDERLINE_THICKNESS , T1_BLEND_ITALIC_ANGLE , /* required fields in a Private blend dictionary */ T1_BLEND_BLUE_VALUES , T1_BLEND_OTHER_BLUES , T1_BLEND_STANDARD_WIDTH , T1_BLEND_STANDARD_HEIGHT , T1_BLEND_STEM_SNAP_WIDTHS , T1_BLEND_STEM_SNAP_HEIGHTS , T1_BLEND_BLUE_SCALE , T1_BLEND_BLUE_SHIFT , T1_BLEND_FAMILY_BLUES , T1_BLEND_FAMILY_OTHER_BLUES , T1_BLEND_FORCE_BOLD , T1_BLEND_MAX /* do not remove */ } T1_Blend_Flags ; /* these constants are deprecated; use the corresponding */ /* ` T1_Blend_Flags ` values instead */ # define t1_blend_underline_position T1_BLEND_UNDERLINE_POSITION # define t1_blend_underline_thickness T1_BLEND_UNDERLINE_THICKNESS # define t1_blend_italic_angle T1_BLEND_ITALIC_ANGLE # define t1_blend_blue_values T1_BLEND_BLUE_VALUES # define t1_blend_other_blues T1_BLEND_OTHER_BLUES # define t1_blend_standard_widths T1_BLEND_STANDARD_WIDTH # define t1_blend_standard_height T1_BLEND_STANDARD_HEIGHT # define t1_blend_stem_snap_widths T1_BLEND_STEM_SNAP_WIDTHS # define t1_blend_stem_snap_heights T1_BLEND_STEM_SNAP_HEIGHTS # define t1_blend_blue_scale T1_BLEND_BLUE_SCALE # define t1_blend_blue_shift T1_BLEND_BLUE_SHIFT # define t1_blend_family_blues T1_BLEND_FAMILY_BLUES # define t1_blend_family_other_blues T1_BLEND_FAMILY_OTHER_BLUES # define t1_blend_force_bold T1_BLEND_FORCE_BOLD # define t1_blend_max T1_BLEND_MAX A set of flags used to indicate which fields are present in a given blend dictionary (font info or private).

FT_WinFNT_ID_OEM From Michael Poettgen <michael@poettgen.de>: The \u2018Windows Font Mapping\u2019 article says that FT_WinFNT_ID_OEM is used for the charset of vector fonts, like modern.fon , roman.fon , and script.fon on Windows. The \u2018CreateFont\u2019 documentation says: The FT_WinFNT_ID_OEM value specifies a character set that is operating-system dependent. The \u2018IFIMETRICS\u2019 documentation from the \u2018Windows Driver Development Kit\u2019 says: This font supports an OEM-specific character set. The OEM character set is system dependent. In general OEM, as opposed to ANSI (i.e., \u2018cp1252\u2019), denotes the second default codepage that most international versions of Windows have. It is one of the OEM codepages from https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers , and is used for the \u2018DOS boxes\u2019, to support legacy applications.
