+2015-06-06 Ashish Azad <ashish.azad@samsung.com>
+
+ Fix Savannah bug #45260.
+
+ * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo.
+
+2015-06-03 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix memory leak.
+
+ Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+ http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+ there is an example code to trigger the bug.
+
+ * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
+ data before allocating again. Bug most probably introduced four
+ years ago in version 2.4.3.
+
+2015-06-02 Werner Lemberg <wl@gnu.org>
+
+ [raster] Add more tracing.
+
+ * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
+ (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
+ Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
+
+2015-06-01 Werner Lemberg <wl@gnu.org>
+
+ [truetype] While tracing opcodes, show code position and stack.
+
+ * src/truetype/ttinterp.c: Change all existing TRACE7 calls to
+ TRACE6.
+ (opcode_name): Add string lengths.
+ (TT_RunIns): Implement display of code position and stack.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make private point numbers work correctly.
+
+ This is completely missing in Apple's documentation: If a `gvar'
+ tuple uses private point numbers (this is, deltas are specified for
+ some points only), the uncovered points must be interpolated for
+ this tuple similar to the IUP bytecode instruction. Examples that
+ need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+ * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+ tt_handle_deltas): New functions.
+ (TT_Vary_Get_Glyph_Deltas): Renamed to...
+ (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+ points and does no longer return an array of deltas.
+ Add tracing information.
+ Call `tt_handle_deltas' to interpolate missing deltas.
+ Also fix a minor memory leak in case of error.
+
+ * src/truetype/ttgxvar.h: Updated.
+
+ * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
+ load_truetype_glyph): Updated.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make intermediate tuplets work at extrema.
+
+ * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Add tracing information to GX code.
+
+ * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
+ ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
+ TT_Set_Var_Design, tt_face_vary_cvt): Do it.
+
+2015-05-28 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/apinames.c (names_dump): Fix invalid reference.
+
+ Problem reported by Guzman Mosqueda, Jose R
+ <jose.r.guzman.mosqueda@intel.com>.
+
+2015-05-24 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix commit from 2015-05-22.
+
+ * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
+ with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.
+
+ Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix return values of GETINFO bytecode instruction.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
+ `vertical_lcd' and `gray_cleartype'.
+
+ * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
+ Change `symmetrical smoothing' to TRUE, since FreeType produces
+ exactly this.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+ values for symmetrical smoothing, namely 11/18.
+ Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+ (12/19).
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (TT_ExecContext):
+ s/subpixel/subpixel_hinting.
+
+ * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
+
+2015-05-22 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Support selector index 3 of the INSTCTRL instruction.
+
+ This flag activates `native ClearType hinting', disabling backwards
+ compatibility mode as described in Greg Hitchcocks whitepaper. In
+ other words, it enables unrestricted functionality of all TrueType
+ instructions in ClearType.
+
+ * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
+ unconditionally.
+ (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
+ `GS.instruct_control' is active.
+
+ * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
+ (Ins_GETINFO): Updated.
+
+ * docs/CHANGES: Document it.
+
+2015-05-20 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
+ argument.
+
+2015-05-17 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix loading of composite glyphs.
+
+ * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+ ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+ unsigned. I trust `ttx' (which has exactly such code) that it does
+ the right thing here...
+
+ The reason that noone has ever noticed this bug is probably the fact
+ that point-aligned subglyphs are rare, as are subglyphs with a
+ number of points in the range [128;255], which is quite large (or
+ even in the range [32768;65535], which is extremely unlikely).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] Make the `*curveto' operators more tolerant.
+
+ * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
+ `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+ pulling values off the stack until the stack is exhausted.
+ Implicitly the stack must be a multiple (or for subtly different
+ behaviour) a multiple plus a specific number of extra values deep.
+ If that's not the case, enforce it (as the old code did).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [cff] fix incremental interface with new cff code.
+
+ * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
+ interface to retrieve glyph data for a SEAC, it be left to the
+ incremental interface callback to apply the encoding to raw
+ character index (as it was in the previous code).
+
+2015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [autofit] Speed up IUP.
+
+ * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
+ the same position from true interpolation, use `scale' to reduce
+ divisions.
+
+2015-04-28 Werner Lemberg <wl@gnu.org>
+
+ [cff] Use `name' table for PS name if we have a SFNT-CFF.
+
+ This follows the OpenType 1.7 specification. See
+
+ http://tug.org/pipermail/tex-live/2015-April/036634.html
+
+ for a discussion.
+
+ * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we
+ have an SFNT.
+
+2015-04-27 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [truetype] Speed up IUP.
+
+ * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial
+ snapping to the same position from true interpolation.
+
+2015-04-21 Werner Lemberg <wl@gnu.org>
+
+ [autofit] By default, enable warping code but switch off warping.
+
+ Suggested by Behdad.
+
+ * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER.
+
+ * src/autofit/afmodule.c (af_autofitter_init): Initialize `warping'
+ with `false'.
+
+2015-04-21 Werner Lemberg <wl@gnu.org>
+
+ * docs/CHANGES: Updated.
+
+2015-04-21 Werner Lemberg <wl@gnu.org>

+ [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.
+
+2015-04-10 Werner Lemberg <wl@gnu.org>
+
+ [cff] Update advance width handling to OpenType 1.7.
+
+ Problem reported by Behdad.
+
+ * src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case
+ separately.
+
+ * src/cff/cffgload.c (cff_slot_load): Use advance width and side

+
+2015-03-21 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [base] Optimize `FT_Angle_Diff'.

+ of angle values, so that the remainder is not really necessary.
+
+ * src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder.

+
+ [raster] Fix Savannah bug #44022.
+
+ Add fallback for glyphs with degenerate bounding boxes.
+
+ If a glyph has only one very narrow feature, the bbox can end up
+ with either the width or height of the bbox being 0, in which case
+ no raster memory is allocated and no attempt is made to render the
+ glyph. This is less than ideal when the drop-out compensation in
+ the rendering code would actually result in the glyph being
+ rendered.
+
+ This problem can be observed with the `I' glyph (gid 47) in the
+ Autodesk RomanS TrueType font.
+
+ * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
+ dimension is zero to explicitly round up/down (instead of simply
+ round).
+
+2015-01-17 Werner Lemberg <wl@gnu.org>
+
+ Add some tools to handle yearly copyright notice updates.

+ We are now following the GNU guidelines: A new release automatically
+ means that the copyright year of all affected files gets updated; it
+ is no longer used to track years of modification changes.
+
+ * src/tools/update-copyright-year: New Perl script.
+ * src/tools/update-copyright: New shell script that calls
+ `update-copyright-year' on all files.
+ * src/tools/no-copyright: Exceptions that should not be handled by
+ `update-copyright'
+

+
+ [autofit] Add embedded array of segments and edges.
+
+ Avoids multiple mallocs per typical glyphs.
+
+ With this and recent changes to avoid mallocs, the thread-safe
+ stack-based loader is now as fast as the previous model that had one
+ cached singleton.
+
+ * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):
+ New macros.
+ (AF_AxisHintsRec): Add two arrays for segments and edges.
+
+ * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate
+ data if number of segments exceeds given threshold value.
+ (af_axis_hints_new_edge): Only allocate data if number of edges

+ Update prototype.
+
+ * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'

+ * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local
+ `hints' object.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [autofit] Reuse slot glyph loader.
+
+ No need to create a new glyph loader; we can reuse the one from
+ `slot->internal->loader'. It's hard to tell why it was written that
+ way originally, but new code looks sound and correct to me, and
+ avoids lots of allocations.
+
+ * src/autofit/afloader.c (af_loader_init): Change return type to
+ `void'.
+ Don't call `FT_GlyphLoader_New'.
+ (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
+ (af_loader_load_g): Update code to use `internal->loader', which
+ doesn't need copying of data.
+
+ * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
+ Update prototype.
+
+ * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [autofit] Remove (unused) support for composite glyphs.
+
+ We never have to deal with composite glyphs in the autohinter, as
+ those will be loaded into FORMAT_OUTLINE by the recursed
+ `FT_Load_Glyph' function.
+
+ In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+ FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+ FT_LOAD_NO_HINTING:
+
+ /* resolve load flags dependencies */
+
+ if ( load_flags & FT_LOAD_NO_RECURSE )
+ load_flags |= FT_LOAD_NO_SCALE |
+ FT_LOAD_IGNORE_TRANSFORM;
+
+ if ( load_flags & FT_LOAD_NO_SCALE )
+ {
+ load_flags |= FT_LOAD_NO_HINTING |
+ FT_LOAD_NO_BITMAP;
+
+ load_flags &= ~FT_LOAD_RENDER;
+ }
+
+ and as such the auto-hinter is never called. Thus, the recursion in
+ `af_loader_load_g' never actually happens. So remove the depth
+ counter as well.
+
+ * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+ parameter.
+ <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+ (af_loader_load_glyph): Updated.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Fix uninitialized memory access.
+
+ Apparently `ras.cProfile' might be uninitialized. This will be the
+ case if `ras.top == ras.cProfile->offset', as can be seen in
+ `End_Profile'. The overshoot code introduced in a change `Fix B/W
+ rasterization of subglyphs with different drop-out modes.' (from
+ 2009-06-18) violated this, accessing `ras.cProfile->flags'
+ unconditionally just before calling `End_Profile' (which then
+ detected that `cProfile' is uninitialized and didn't touch it).
+
+ This was harmless, and was not detected by valgrind before because
+ the objects were allocated on the `raster_pool', which was always
+ initialized. With recent change to allocate raster buffers on the
+ stack, valgrind now reported this invalid access.
+
+ * src/raster/ftraster.c (Convert_Glyph): Don't access an
+ uninitialized `cProfile'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [smooth] Fix uninitialized memory access.
+
+ Looks like `ras.span_y' could always be used without initialization.
+ This was never detected by valgrind before because the library-wide
+ `raster_pool' was used for the worker object and `raster_pool' was
+ originally zero'ed. But subsequent reuses of it were using `span_y'
+ uninitialized. With the recent change to not use `render_pool' and
+ allocate worker and buffer on the stack, valgrind now detects this
+ uninitialized access.
+
+ * src/smooth/ftgrays.c (gray_raster_render): Initialize
+ `ras.span_y'.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Don't initialize unused `driver->glyph_loader'.

+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Don't allocate `library->raster_pool' anymore.
+
+ It's unused after the following commits:
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+ serve, which is, to adjust the pool size. But the pool is now
+ allocated on the stack on demand.
+
+ * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [base] Do not reorder library->renderers upon use.
+
+ Instead of keeping `library->renderers' in a MRU order, just leave
+ it as-is. The MRU machinery wasn't thread-safe.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't fail choosing rasterizer
+ (FT_Err_Cannot_Render_Glyph).
+
+ Easiest to see that crash was to add a `printf' (or otherwise let
+ thread yield in FT_Throw with debugging enabled).
+
+ * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+ (FT_Outline_Render): Don't call `FT_Set_Renderer'.

+2015-01-14 Behdad Esfahbod <behdad@behdad.org>

+ [raster] Allocate render pool for mono rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is

+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't crash in the monochrome rasterizer.
+
+ * src/raster/ftraster.c (black_TRaster): Remove `buffer',

+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ It was off by default and couldn't be turned on at runtime. And the
+ smooth rasterizer superceded it over ten years ago. No point in

+ with FreeType 1.
+

+
+ * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,

+
+ [smooth] Allocate render pool for smooth rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is

+ [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+ Previously the code had stipulation for using a per-TT_Size exec

+
+ [autofit] Better fix for conversion specifiers in debug messages.
+
+ Using `%ld' for pointer differences causes warnings on 32bit
+ platforms. The correct type would be (the relatively new) `%td',
+ however, this is missing on some important platforms.
+
+ This patch improves the change from 2014-11-28.
+
+ * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
+ pointer differences are always sufficiently small.
+ (af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
+ af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
+
+2014-12-03 Werner Lemberg <wl@gnu.org>
+
+ FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.
+
+ All public FreeType enumeration and flag values are uppercase...
+
+ * include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards
+ compatilibity, retain the old values as macros.
+
+ * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c
+ (get_sfnt_table): Updated.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ * include/*: Improve structure of documentation.
+
+ . Add and update many `<Order>' tags.
+ . Apply various documentation fixes.
+ . Remove details to deprecated (or never implemented) data.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Always handle `<Order>' section elements.
+
+ Previously, those elements were handled only for sections present in
+ a `<Sections>' chapter element.
+
+ * src/tools/docmaker/content.py (ContentProcessor::finish):
+ Implement it.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Properly handle empty rows in Synopsis.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ `&nbsp;' for empty fields.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Thinko.

+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Emit `/empty/' string for first element also.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Honour empty lines in `<Order>' section element.
+
+ This greatly improves the readability of the `Synopsis' links.
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Insert string `/empty/' between items.
+
+ * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it
+ robust against nonexistent keys.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ empty <td> elements for `/empty/'.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Ensure Python 3 compatibility.
+
+ * src/tools/docmaker/content.py (ContentProcessor::set_section,

+ keyword.
+
+ * src/tools/docmaker/formatter.py (Formatter::__init__): Replace
+ sorting function with a key generator.
+ (Formatter::add_identifier): Replace `has_key' function with `in'

+ (index_sort): Replaced by...
+ (index_key): ... this new key generator (doing exactly the same).
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Don't output a block multiple times.
+
+ This bug was hidden by not processing all lines of `<Order>' blocks.
+
+ * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter
+ out field names.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>

+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Allow empty lines in `<Order>' blocks.
+
+ Before this patch, the suggested order of entries stopped at the
+ first empty line.
+
+ Obviously, nobody noticed that this problem caused a much reduced
+ set of links in the `Synopsis' sections; in particular, the
+ `<Order>' blocks contain a lot of entries that wouldn't be listed
+ otherwise...
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ New function to iterate over all items.
+ (DocSection::process): Use it.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>

+ together with proper CSS.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Provide higher-level markup and simplify HTML.
+
+ * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'
+ elements, use CSS descendants (of class `section') to format the
+ data.
+
+ Also remove reduntant <p> and <br> elements, replacing them with
+ proper CSS.
+
+ Globally reduce page width to 75%.
+
+ (block_header): Rename <div> class to `section'.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Add `top' links after blocks.

+

+
+ Make fields align horizontally relative to full line width.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/docmaker/tohtml.py: Fix index and TOC templates.
+
+ This thinko was introduced 2014-11-27.
+
+2014-11-28 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Format field lists with CSS.
+
+ This also simplifies the inserted HTML code.
+

+
+2014-11-28 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Replace empty `<td>' with CSS.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do
+ it.
+
+2014-11-28 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.
+
+ * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.

+
+2014-11-27 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Replace `name' attribute of `<a>' with `id'.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it.
+
+2014-11-27 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
+
+ For `Index' and `TOC' links, we now simply use the `text-align' CSS
+ property of `<td>' to enforce flush-left and flush-right,
+ eliminating the hack with an empty, full-width `<td>' element
+ inbetween.
+
+ The change also enforces the same (smaller) size for all index and
+ TOC links.
+
+2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),

+ On certain platforms (c -> js with emscripten) this causes

+
+ Before this patch, it was impossible to ever call DELTAP[123] in

+
+ We now follow the whitepaper more closely so that DELTAP[123]

+
+ [autofit] Fix Savannah bug #42148.
+
+ The adaptation of the cjk auto-hinter module to blue stringsets in
+ 2013-08-25 had three severe bugs. Mea culpa.
+
+ 1. Contrary to the latin auto-hinter, characters for reference and
+ overshoot values of a blue zone are specified separately. Due to
+ the screwed-up change it didn't work at all.
+
+ 2. A boolean comparison was erroneously replaced with a cast,
+ causing invalid results with the `^' operator later on. The
+ visual artifact caused by this problem is the topic of the bug
+ report.
+
+ 3. Two flag values were inverted, causing incorrect assignment of
+ reference and overshoot values.
+
+ * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
+ syntax to have both reference and overshoot characters in a single
+ string. This is error #1.
+ Add extensive comments.
+
+ * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
+ longer used.
+ (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
+ This is error #3.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
+ Use character `|' to separate characters for reference and overshoot
+ values.
+ Improve tracing messages, synchronizing them with the latin
+ auto-hinter.
+ (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
+ This is error #2.
+ (af_cjk_align_linked_edge): Add tracing message.
+
+ * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
+ used.

+
+ [autofit] More coverage fixes for complex scripts.
+
+ * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

+2014-04-12 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Redesign the recognition algorithm of strong points.
+
+ In particular, local extrema without horizontal or vertical segments
+ are better recognized:
+
+ + A + D
+ \ /
+ \ /
+ \ /
+ \ /
+ \ + C
+ \ /
+ B +/
+
+ If the distances AB and CD are large, point B wasn't previously
+ detected as an extremum since the `ft_corner_is_flat' function
+ `swallowed' BC regardless of its direction, tagging point B as weak.
+ The next iteration started at B and made `ft_corner_is_flat' swallow
+ point C, tagging it as weak also, et voilà.
+
+ To improve that, another pass gets now performed before calling
+ `ft_corner_is_flat' to improve the `topology' of an outline: A
+ sequence of non-horizontal or non-vertical vectors that point into
+ the same quadrant are handled as a single, large vector.
+
+ Additionally, distances of near points are now accumulated, which
+ makes the auto-hinter handle them as if they were prepended to the
+ next non-near vector.
+
+ This generally improves the auto-hinter's rendering results.
+
+ * src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
+
+ * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
+ `AF_FLAG_NEAR'.
+
+2014-04-05 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Improve scoring algorithm for identifying stems.
+
+ Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
+
+ The new algorithm takes care of the width of stems: If the distance
+ between two segments is larger than the largest stem width, the
+ demerits quickly increase for larger distances. This improves
+ hinting of slanted fonts (especially if the inner parts of serifs
+ have non-horizontal `shoulders'), avoiding false stem links.
+
+ * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
+ stem width (if available) to compute better demerits for distances
+ between stems.
+ (af_latin_hints_detect_features): Pass stem width array and array
+ size.
+ (af_latin_metrics_init_widths): Updated to use original algorithm.

+
+ Rewrite library option handling in `configure'.
+
+ o Introduce `auto' value for `--with-XXX' library options; this is
+ now the default.
+
+ o First use `pkg-config' for library detection, then fall back to
+ other tests.
+
+ * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
+ --with-harfbuzz): Rewrite.
+ Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
+ variables to collect data for `freetype2.pc' and `freetype-config'.
+ (FT2_EXTRA_LIBS): Renamed to ...
+ (ft2_extra_libs): This since it gets no longer substituted.
+ (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG):
+ New output variables, replacing `XXX_PKG' and `LIBXXX'.
+ Add notice at the end of `configure' showing the library
+ configuration.
+
+ * builds/unix/freetype-config.in (--static): New command line
+ option.
+ (libs): Updated.
+ (staticlibs): New variable, to be used if `--static' is given.

+ Avoid `long long' warnings with older gcc compilers.
+ Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
+
+ * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for

+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ Use pkg-config for detecting libpng and libbz2 also.
+
+ * builds/unix/configure.raw (HAVE_PKG): New variable.
+ Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.

+
+ [bdf] Fix Savannah bug #41692.
+
+ bdflib puts data from the input stream into a buffer in chunks of
+ 1024 bytes. The data itself gets then parsed line by line, simply
+ increasing the current pointer into the buffer; if the search for
+ the final newline character exceeds the buffer size, more data gets
+ read.
+
+ However, in case the current line's end is very near to the buffer
+ end, and the keyword to compare with is longer than the current
+ line's length, an out-of-bounds read might happen since `memcmp'
+ doesn't stop properly at the string end.
+
+ * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
+ stop at string ends.

+ [ftrfork] Fix the face order difference between POSIX and Carbon.
+
+ The fragmented resources in Suitcase and .dfont should be reordered
+ when `POST' resource for Type1 is being restored, but reordering of
+ sfnt resources induces the different face order. Now the ordering
+ is restricted to `POST' resource only, to prevent the different
+ order issue (e.g. the face index in the fontconfig cache generated
+ with Carbon framework is incompatible with that by FreeType 2
+ without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

+
+ [autofit] Introduce `coverages'.
+
+ Coverages are the interface to the HarfBuzz library to acces
+ OpenType features for handling glyphs not addressable by the cmap.
+
+ Right now, compilation of HarfBuzz is only added to the development
+ build. A solution for standard build mode will be delayed until
+ HarfBuzz gets split into two libraries to avoid mutual dependencies
+ between FreeType and HarfBuzz.
+
+ Note that this is only a first step in handling coverages, basically
+ providing the framework only. Code for handling selected OpenType
+ features (this is, actually using the data in `afcover.h') will
+ follow.

+
+ * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

+ incorrect amount of darkening.

+
+ * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
+
+ This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
+ is to use a previous darkening amount when producing an unhinted,
+ unscaled outline. This can cause autohint samples in ftgrid and
+ ftview to be based on darkened CFF outlines instead of unhinted,
+ undarkened ones.
+
+2013-09-29 Dave Arnold <darnold@adobe.com>
+
+ Fix Savannah bug #39295.
+
+ The bug was caused by switching to the initial hintmap (the one in
+ effect when `moveto' executes) just before drawing the final element
+ in the charstring. This ensured that the path was closed (in both
+ Character Space and Device Space). But if the final element was a
+ curve and if the final hintmap was different enough from the initial
+ one, then the curve was visibly distorted.
+
+ The first part of the fix is to draw the final curve using the final
+ hintmap as specified by the charstring. This corrects the
+ distortion but does not ensure closing in Device Space. It may
+ require the rasterizer to automatically generate an extra closing
+ line. Depending on the hintmap differences, this line could be from
+ zero to a couple pixels in length.
+
+ The second part of the fix covers the case where the charstring
+ subpath is closed with an explicit line. We now modify that line's
+ end point to avoid the distortion.
+
+ Some glyphs in the bug report font (TexGyreHeros-Regular) that show
+ the change are:
+
+ 25ppem S (98)
+ 24ppem eight (52)
+ 25.5ppem p (85)
+
+ Curves at the *end* of a subpath are no longer distorted. However,
+ some of these glyphs have bad hint substitutions in the middle of a
+ subpath, and these are not affected.
+
+ The patch has been tested with a set of 106 fonts that shipped with
+ Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
+ Google Fonts. There are 1.5 million glyphs, of which some 20k are
+ changed with the fix. A sampling of a few hundred of these changes
+ have been examined more closely, and the changes look good (or at
+ least acceptable).
+
+ * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
+ to indicate that we synthesize a closepath line.
+
+ * src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
+ (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
+ `lineto' operator) and adjust hint zone.
+ For synthesized closing lines, use end point in first hint zone.
+ (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
+ particular, shift the detection of zero-length lines from character
+ space to device space.
+ (cf2_glyphpath_closeOpenPath): Remove assertion.
+ Updated.

+
+ [autofit] Introduce data file for blue strings.
+
+ The idea is to have a central file which gets processed by a Perl
+ script to create proper `.c' and `.h' files using templates. There
+ are two other reasons to do that:
+
+ . The data file should be easily readable. We use UTF-8 encoding
+ which then gets converted to single bytes.
+
+ . Since the number of supported scripts will increase soon, the
+ current usage of blue string arrays is a waste of space. Using
+ the Perl script it is possible to imitate jagged arrays,
+ defining enumeration constants as offsets into the arrays.
+
+ This commit only adds files without changing any functionality.

+
+ Speed up ARMv7 support.
+
+ When building for ARMv7 with thumb2 instructions, the optimized
+ `FT_MulFix_arm' assembly routine was not being used.
+
+ The reason for this is in the `ftconfig.h' header, namely:
+
+ - The assembly routine uses the `smull' instruction which is not
+ available when generating Thumb-1 machine code. It is available
+ in Thumb-2 mode, though.
+
+ - The header was written a long time ago before Thumb-2 became
+ widely popular (e.g. with Android). So it simply doesn't use the
+ assembly routine if the `__thumb__' built-in macro is defined.
+
+ - When compiling in Thumb-2 mode, the compiler will define both
+ `__thumb__' and `__thumb2__'.
+
+ By checking for `(__thumb2__ || !__thumb__)', we ensure that the
+ assembly routine is only avoided when generating Thumb-1 code.
+
+ Given that this is performance-sensitive function, this improves
+ `ftbench' as follows on a Galaxy Nexus:

+
+ A new load flag, FT_LOAD_COLOR, makes FreeType load color
+ embedded-bitmaps, following this draft specification
+
+ https://color-emoji.googlecode.com/git/specification/v1.html
+
+ which defines two new SFNT tables, `CBDT' and `CBLC' (named and
+ modeled after `EBDT' and `EBLC', respectively). The color bitmaps
+ are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
+ pre-multiplied sRGB images. If PNG support is available, PNG color
+ images as defined in the same proposed specification are supported
+ also.
+
+ Note that color bitmaps are converted to grayscale if client didn't
+ ask for color.
