-<h2><a name="Font_license"></a>Font license</h2>
-<p>
-As we note in <a href="Fonts.htm#Add_fonts">"Adding your own fonts"</a>,
-you have to read the license of fonts carefully.
-The fact you obtain the fonts legally does not mean
-always that you can use them with Ghostscript.
-
-Usually, outline fonts for east Asian scripts are licensed under
-more restricted conditions in comparison with ASCII or Latin
-fonts, because they must provide a large number of glyphs,
-more than 8000 glyphs.
-
-For example, Adobe licenses the Asian font package for Acrobat
-Reader as "solely for Acrobat Reader". So even if your system
-have pre-installed Acrobat Reader, you cannot use its Asian fonts
-in Ghostscript.
-
-
-<h2><a name="About_OCF_fonts"></a>About OCF fonts</h2>
-<p>
-Prior to PostScript level 2015, PostScript fonts for multibyte encoded
-script (Chinese, Japanese, Korean and Vietnamese etc) were implemented
-as a collection of many elemental Type1/Type3 fonts and a selector.
-Today these fonts are known as OCF (Original Composite Font).
-Ghostscript fully supports OCF.
-
-
-<p>
-Adobe has announced that OCF is obsolete.
-For details of OCF, refer<br>
-<blockquote>

-
-<h2><a name="About_CID_keyed_fonts"></a>About CID-keyed fonts</h2>
-<p>
-In PostScript level 2015, Adobe introduced a new font format
-"CID-keyed font" for CJK scripts.
-For details of the CID-keyed font format, refer<br>
-<blockquote>

-Ghostscript provides the basic functionalities of CID-keyed fonts,
-but the "rearranged font" feature is not implemented.
-The present functionalities are enough for common usage.
-Some Japanese PostScript programs expect that any system that
-supports CID-keyed fonts will also support "rearranged font".
-Such programs do not work well with ghostscript.
-Chinese and Korean scripts were never officially supplied by OCF,
-so such problems are rare.
-
-<p>
-The CID-keyed font format has a double layered structure.
-The lower layer is a CID-keyed font. The public interface of the
-CID-keyed font is a 16-bit CID (character identifier) number
-which is given to each unique "glyph" for subsets of various scripts.
-This is not a "character" code like ASCII/Unicode/etc.
-Adobe specifies CIDs for CJK scripts:
-Adobe-CNS1 &amp 2 (Traditional Chinese Hanzi glyphs),
-Adobe-GB1 (Simplified Chinese Hanzi glyphs),
-Adobe-Japan1 &amp; 2 (Japanese Kana and Kanji glyphs),
-Adobe-Korea1 &amp; 2 (Hangul and Hanja glyphs),
-Adobe-HongKong1 (Traditional Chinese Hanzi in HongKong),
-and Adobe-Vietnam1 (Chu-Han).
-The catalogues of glyphs for some CIDs are published by Adobe,
-refer Technical Notes service of Adobe:<br>
-<blockquote>
-<a
-href="http://partners.adobe.com/asn/developer/technotes/fonts.html"
-class="offsite">
-http://partners.adobe.com/asn/developer/technotes/fonts.html</a>
-</blockquote>
-
-
-
-
-<p>
-A CID-keyed font must provide the CID number interface,
-but the format of the glyph data may vary:<br>
-<ul>
-<li>CIDFontType 0 (FontType 9, CID-keyed Type1 font),</li>
-<li>CIDFontType 1 (FontType 10, CID-keyed Type3 font),</li>
-<li>CIDFontType 2 (FontType 11, CID-keyed Type42 font - TrueType)</li>
-</ul>
-
-
-
-
-
-
-<p>
-The higher layer is a CMap. A CMap provides a map from the multibyte
-character code to the CID of corresponding glyph, under a specified
-encoding system. PostScript fonts must provide a character
-code interface, so a bare CID-keyed font cannot be used as normal
-PostScript font without a CMap (e.g. <tt>findfont</tt>, <tt>show</tt>,
-etc are not usable, however <tt>glyphshow</tt> operator is usable for
-a bare CID-keyed font).
-In a CID-keyed font system, the various encoding systems can be supported
-by higher layer only. The lower layer is sharable.
-
-<p>
-A CMap file is stored in the /CMap resource category and the
-CID-keyed font file is stored in the /CIDFont resource category.
-Several operators introduced for CID-keyed fonts assume these locations,
-so CMap and CIDFont must not be stored in the /Font resource used
-traditionally used by PostScript fonts.
-
-<p>
-For "named resource category", refer
-<a href="Use.htm#PS_resources">Finding PostScript Level 2 resources</a> of Ghostscript.
-
-<p>
-Adobe distributes their official CMap (redistributable but no modification
-is permitted) on O'Reilly ftp site:
-<blockquote>
-<a
-href="ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/"
-class="offsite">
-ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/</a>
-</blockquote>
-
-To use CID-keyed font, these CMap files must be installed into the CMap
-resource directory.
-
-
-
-<h3><a name="About_CIDFontType0"></a>CIDFontType 0</h2>
-<p>
-CIDFontType0 is the most standard CIDFont of PostScript.
-It consists of two separated parts: PostScript
-program and attached binary data. The glyph data is stored in attached
-binary part and is dynamically accessed. In comparison with OCF,
-loading a CIDFontType0 is light-weight and comsumes less memory.
-
-<p>
-To make Ghostscript recognize a CIDFontType0 font is easy.
-If the CIDFontType0 font file is installed into a directory named "CIDFont"
-under GenericResourceDir (see
-<a href="Use.htm#PS_resources">Finding PostScript Level 2 resources</a>),
-Ghostscript will find it when searching for resources in /CIDFont category.
-
-
-
-
-<h3><a name="About_CIDFontType2"></a>CJK TrueType font and CIDFontType 2</h2>
-<p>
-In PostScript 2010, Adobe introduced the Type42 font format
-to embed a host-based TrueType font into a PostScript program.
-For details of the Type42 font format, refer to
-<blockquote>
-The Type 42 Font Format Specification. Technical Note #5012
-<a
-href="http://partners.adobe.com/asn/developer/pdfs/tn/5012.Type42_Spec.pdf"
-class="offsite">
-"http://partners.adobe.com/asn/developer/pdfs/tn/5012.Type42_Spec.pdf
-</a>
-</blockquote>
-CIDFontType2 is a CID extension of the Type42 font format.
-If Ghostscript is compiled with
-<a href="Make.htm#Features_and_devices">ttfont device</a>
-and CMap files are installed, Ghostscript is capable of
-handling CIDFontType2 resource embedded in PostScript program
-or PDF document.
-The Type42 font specification notes that Type42 is an installable font
-format, but there's no font distributed in the Type42 format.
-This is a big difference from the standard PostScript fonts: Type1, Type3
-and CIDFontType0.
-
-<p>
-Ghostscript now provides "on-the-fly CIDFontType2 converter"
-for CJK TrueType, similar to the "on-the-fly Type42 converter" for
-Roman TrueType fonts.
-This does not mean you can perfectly substitute a required PostScript
-fonts by a TrueType font. CJK TrueType font often lack many
-non-popular glyphs and a few popular glyphs in Adobe CID.
-As a result, a TrueType font
-(designed as screen font for window system) cannot be a perfect
-replacement for an Adobe PostScript font
-Refer <a href="CJKTTCID.htm">CJKTTCID.htm</a> for further particulars.
-
-<p>
-The operator <b><tt>.openttcidfont</tt></b> constructs CIDFontType2
-font dictionary from a given TrueType font. <b><tt>.openttcidfont</tt></b>
-requires extra CMaps for PDF available from:
-
-<blockquote>
-<a
-href="http://partners.adobe.com/asn/developer/technotes/acrobatpdf.html"
-class="offsite">
-http://partners.adobe.com/asn/developer/technotes/acrobatpdf.html
-</a>
-</blockquote>
-
-The basic syntax of <b><tt>.openttcidfont</tt></b> is:<br>
-<blockquote>
-<b><tt>&lt;ttf_filename&gt; .openttcidfont</tt></b><br>
-</blockquote>
-
-<p>
-When a font file in Microsoft's TrueType Collection format
-(a font file with suffix <b><tt>.ttc</tt></b>
- includes multiple fonts in single file) is given,
-the first font in it is used by default.
-To specify a font manually, index of the font should be passed
-to <b><tt>.openttcidfont</b></tt>, as:<br>
-
-<blockquote>
-<b><tt>&lt;ttc_filename&gt; 2 .openttcidfont</tt></b><br>
-</blockquote>
-
-<p>
-Old TrueType fonts were encoded by CJK-system specific encodings
-(e.g. Big5, Johab, ShiftJIS, etc) without stating what encoding
-is used.
-On the other hand, recent TrueType fonts are encoded by Unicode,
-but included glyphs are limited to specific language.
-By default, <b><tt>.openttcidfont</tt></b> detects encoding of
-TrueType font and the suitable Adobe CID automatically, but if
-you have trouble, these parameters should be specified manually.
-To specify Adobe CID and TrueType encoding explicitly, pass a name
-object as:
-
-<blockquote>
-<b><tt>&lt;ttf_filename&gt; /Adobe-Japan1-ShiftJIS .openttcidfont</tt></b><br>
-</blockquote>
-
-In such syntax, Adobe-Japan1 specifies Adobe CID to be mapped,
-and ShiftJIS specifies the encoding of TrueType fonts.
-Currently supported Adobe CIDs are:<br>
-
-<blockquote>
-<b><tt>Adobe-CNS1</tt></b><br>
-<b><tt>Adobe-GB1</tt></b><br>
-<b><tt>Adobe-Japan1</tt></b><br>
-<b><tt>Adobe-Japan2</tt></b><br>
-<b><tt>Adobe-Korea1</tt></b><br>
-</blockquote>
-
-and, supported TrueType encodings are:<br>
-
-<blockquote>
-<b><tt>Big5</tt></b><br>
-<b><tt>Johab</tt></b><br>
-<b><tt>PRC</tt></b><br>
-<b><tt>ShiftJIS</tt></b><br>
-<b><tt>Unicode</tt></b><br>
-<b><tt>Wansung</tt></b><br>
-</blockquote>
-
-In addition about on-the-fly CIDFontType2 conversion of TrueType fonts
-(of Big5, PRC, ShiftJIS, Wangsung), <tt>.openttcidfont</tt> requires
-more extra CMap files which are available from Asian font packages for
-Adobe Acrobat Reader. See <a href="Fonts.htm#CMap_Adobe"> "Adobe
-CMaps" subsection</a> of "Fonts and font facilities supplied with
-Ghostscript" section.
-
-
-
-<h2><a name="About_CIDFnmap"></a>About "CIDFnmap" of Ghostscript</h2>
-<p>
-By applying various CMap to single CIDFont, various font resources
-can be generated. To utilize this feature conveniently, "CIDFnmap"
-is introduced. CIDFnmap is similar to Fontmap, but it handles resource
-name of CIDFont.
-
-<p>
-To map all /Ryumin-Light-* fonts (/Ryumin-Light-H, /Ryumin-Light-RKSJ-H
-etc) derived from /Ryumin-Light CIDFont to those from /WadaMin-Regular,
-following single entry works enough:<br>
-
-<blockquote>
-<b><tt>/Ryumin-Light&nbsp;/WadaMin-Regular&nbsp;;</tt></b><br>
-</blockquote>
-
-Also CIDFnmap can define a resource from a file specified with full path,
-it is convenient to import resource from out of Ghostscript directory tree:<br>
-
-<blockquote>
-<b><tt>/WadaMin-Regular&nbsp;(/usr/lib/X11/fonts/CIDFont/WadaMin-Regular)&nbsp;;</tt></b><br>
-</blockquote>
-
-If the given file is TrueType font, CIDFnmap automatically detect it, and
-execute <b><tt>.openttcidfont</tt></b>:<br>
-
-<blockquote>
-<b><tt>/HG-MinchoL&nbsp;(/usr/openwin/lib/locale/ja/X11/fonts/TT/HG-MinchoL.ttf)&nbsp;;</tt></b><br>
-</blockquote>
-
-Other operands for <b><tt>.openttcidfont</tt></b> (TTC index, CID/encoding
-specification) can be specified as:<br>
-
-<blockquote>
-<b><tt>
-/HeiseiMin-W3H&nbsp;(/usr/openwin/lib/locale/ja/X11/fonts/TT/HeiseiMin-W3H.ttf)&nbsp;/Adobe-Japan2-Unicode&nbsp;;<br>
-</blockquote>
-<blockquote>
-/Ryobi-PGothic&nbsp;(/usr/X11R6/lib/X11/fonts/TrueType/tcgothb.ttc)&nbsp;2&nbsp;/Adobe-Japan1-Unicode&nbsp;;<br>
-</tt></b>
-</blockquote>

-
-<p>
-There are CJK samples in <b><tt>examples/cjk</tt></b>:
-<b><tt>
-all_ac1.ps, all_ag1.ps, all_aj1.ps, all_aj2.ps, all_ak1.ps
-</tt></b>
-(drawing all glyphs in Adobe CID for Traditional Chinese,
-Simplified Chinese, Japanese, Japanese Hojo Kanji, Korean)
-<b><tt>
-gscjk_ac.ps, gscjk_ag.ps, gscjk_aj.ps, gscjk_ak.ps
-</tt></b>
-(drawing short texts in horizontal and vertical writing modes)
-and multilingual sample <b><tt>iso2022.ps</tt></b>
-(this sample loads many fonts for various scripts, quite heavy).
-<b><tt>gscjk_*</tt></b> samples are written in Asian character encoding and
-iso2022.ps is in ISO-2022, not pure ASCII.
-To modify them, an internationalized or binary capable editor
-are recommended.
-
-<p>
-For proofing by PostScript printers (for Asian market),
-these samples use standard printer-based CJK fonts:
-/HYGoThic-Medium, /MSung-Light, /Ryumin-Light, /STSong-Light etc.
-To display them correctly by Ghostscript,
-printer-based fonts must be aliased to available fonts on Ghostscript.
-CIDFnmap.CJK lists known printer-based CJK fonts,
-modify it for your own environment.
