- [mac] Fix ftexport.sym target in Jamfile.
-
- * Jamfile: Update the directories of the header files scanned for
- ftexport.sym. They were incorrect since the migration of the
- header files, on 2015-06-22. Either inexisting include/cache

-
- [smooth] Sub-banding protocol revision.
-
- Rasterization sub-banding is utilized at large sizes while using a
- rather small fixed memory pool. Indeed it is possible to make an
- educated guess how much memory is necessary at a given size for a
- given glyph. It turns out that, for a large majority of European
- glyphs, you should store about 8 times more boundary pixels than
- their height. Or, vice versa, if your memory pool can hold 800
- pixels the band height should be 100 and you should sub-band
- anything larger than that. Should you still run out of memory,
- FreeType bisects the band but you have wasted some time. This is
- what has been implemented in FreeType since the beginning.
-
- It was overlooked, however, that the top band could grow to twice
- the default band size leading to unnecessary memory overflows there.
- This commit fixes that. Now the bands are distributed more evenly
- and cannot exceed the default size.
-
- Now the magic number 8 is really suitable for rather simple European
- scripts. For complex Chinese logograms the magic number should be
- 13 but that is subject for another day.
-
- * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
- protocol.

-
- [mac] Fix Savannah bug #48417.
-
- Mac OS X linker throws errors when `-exported_symbol_list' input
- file includes non-existing symbols. Reported by Ryan Schmidt.
-
- * builds/exports.mk: Exclude ftmac.h from the headers for apinames
- by default. Include it when ftmac.c would be compiled.

-
- * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some
- fields to `TCoord'.

- (gray_convert_glyph): ... to here and update accordingly.
-
-2016-06-22 Alexei Podtelezhnikov <[email protected]>

- modified and the whole FreeType library is recompiled. With this
- change we change the files only if there are real modifications, so
- we can avoid recompilations.
-
-2016-06-09 Werner Lemberg <[email protected]>
-
- [bdf] Check number of properties (#48166).

- it immediately follows non-ASCII characters.
-
- * src/autofit/afscript.h: Ensure whitespace before `*/'.
-
-2016-06-04 Werner Lemberg <[email protected]>
-
- Fix a test for named instances (#48122).
-
- This was missed while giving negative face indices an extended
- meaning.
-
- * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.
-
-2016-05-31 Nikolaus Waxweiler <[email protected]>
-
- [truetype] Let SHPIX move points in the twilight zone in v40.
-
- * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
- the twilight zone. Otherwise, treat SHPIX the same as DELTAP.
- Unbreaks various fonts such as older versions of Rokkitt and DTL
- Argo T Light that would glitch severly after calling ALIGNRP after a

- having the format
-
- (foo) cvn 12345 def
-
-2016-05-28 Werner Lemberg <[email protected]>
-
- * src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
-
- Suggested by Alexei. `UL' is only needed for 16bit compilers, but
- it seems noone is using this anymore (and we no longer test whether
- FreeType compiles in such an environment). Otherwise, it is easy to
- add the postfix to the `AF_UNICODE_RANGE' macro.
-
-2016-05-26 Alexei Podtelezhnikov <[email protected]>
-
- [smooth] Shrink bisection stack.
-
- The convergence of Bézier flatteners is fast with the deviation
- from straight line being assymptotically cut 4-fold on each bisection.
- This justifies smaller bisection stack size.
-
- * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
- (gray_render_conic): Create and use conic `bez_stack'. Move back the
- band analysis from...
- (gray_conic_to): ... here.
- (gray_render_cubic): Create and use cubic `bez_stack'. Move back the
- band analysis from...
- (gray_cubic_to): ... here.
- (gray_move_to): Updated.
-
-2016-05-25 Werner Lemberg <[email protected]>
-
- [autofit] Fixes for Armenian and Gujarati ranges.
-
- * src/autofit/afranges.c (af_armn_uniranges): Corrected.
- (af_guru_nonbase_uniranges): Make U+0A3E a base character.
-
-2016-05-24 Werner Lemberg <[email protected]>
-
- [autofit] Add support for Armenian script.
-
- * src/autofit/afblue.dat: Add blue zone data for Armenian.

-
- * src/autofit/afscript.h: Add Armenian standard characters.
-
- * src/autofit/afranges.c: Add Armenian data.
-
- * src/autofit/afstyles.h: Add Armenian data.
-
-2016-05-23 Werner Lemberg <[email protected]>
-
- * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
-
- This was commented about 10 years ago – I think the reason then to
- disable libtool's `-export-symbols' option was to give some badly
- programmed applications access to internal FreeType functions.
-
- I believe that we should no longer take care of such programs; the
- number of symbols exported should be rather restricted as much as
- possible.
-
-2016-05-22 Werner Lemberg <[email protected]>
-
- [autofit] Add blue-zone support for Gurmukhi script.
-
- This essentially moves the Gurmukhi script from the `Indic' hinter to
- the `Latin' hinter.
-
- * src/autofit/afblue.dat: Add blue zone data for Gurmukhi.
-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
-
- * src/autofit/afscript.h: Add Gurmukhi standard characters and move
- data out of AF_CONFIG_OPTION_INDIC block.
-
- * src/autofit/afranges.c: Move Gurmukhi data out of
- AF_CONFIG_OPTION_INDIC block.
-
- * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
- AF_WRITING_SYSTEM_LATIN.
-
-2016-05-21 Werner Lemberg <[email protected]>
-
- Minor clang++ fixes.
-
- * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c

-
- [autofit] Add support for Georgian scripts.
-
- Georgian is problematic, since `uppercase' forms of Mkhedruli
- (called Mtavruli) are not yet defined in Unicode, which means that
- proper blue zones can't be defined. However, there is already a
- proposal submitted to Unicode; see
-
- http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
-
- Additionally, due to historical reasons, Unicode treats Khutsuri as
- the same script as Mkhedruli, and so does OpenType. However, since
- the two scripts have completely different shapes it can happen that
- blue zones differ considerably. The tag `geok' used here (derived
- from ISO 15924) to differentiate the two scripts is not an OpenType
- tag in use. If we now have a font that contains both glyphs for
- Mkhedruli and Khutsuri, and it uses OpenType features for both also,
- HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
- blue zones for `geok' are not used for glyphs involved in the
- OpenType features.
-
- An issue not yet resolved is which OpenType feature should be used
- to access Mtavruli glyph shapes; right now, FreeType doesn't set up
- support for them, but it is easy to add them later on as soon as
- more information is available.

-
- [autofit] Fix handling of default script.
-
- Patch taken from ttfautohint, commit
- 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
-
- There were two bugs.
-
- - We now use non-standard script tags like `khms' for special
- purposes. However, HarfBuzz maps such tags to `DFLT', and
- without this commit the associated lookups were incorrectly
- assigned to the non-standard tags.
-
- - Let's assume we have a Bengali font, and the font's `DFLT'
- script tag handles the necessary lookups for Bengali, too.
- Without this commit, the `DFLT' lookups were assigned to
- ttfautohint's default script (usually `latn') before the
- standard lookups for Bengali were handled.
-
- We now have the following order while searching for covered
- glyph indices.
-
- special features of scripts (e.g. `sups' for Cyrillic)
- Unicode mappings of scripts
- remaining features of scripts (especially important for Indic
- scripts)
- default features of default script
-
- * src/autofit/afshaper.c, src/autofit/afshaper.h
- (af_shaper_get_coverage): Add boolean parameter to indicate default
- script.
- Update all callers.
-
- * src/autofit/afglobal.c (af_face_globals_compute_style_coverage):

-
- * src/autofit/aflatin.c (af_latin_metrics_init_widths): Do it.
-
-2015-12-09 Werner Lemberg <[email protected]>
-
- [autofit] Thinko.
-
- * src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count
- empty blue zones (bug introduced 2015-12-06).
-
-2015-12-09 Werner Lemberg <[email protected]>
-
- [autofit] Introduce subscript top blue zones.
-
- This feature is mainly for Khmer: The idea is to avoid a clash
- between the top of subscript glyphs and the bottom of normal
- baseline glyphs.
-
- This only works for character clusters mapped to multiple glyphs.
-
- * src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
-
- * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
- macro.
-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
-
- * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE,
- AF_LATIN_BLUE_SUB_TOP): New macros.
-
- * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new
- blue zone property.

- inactive blue zones also.
-
-2015-12-06 Werner Lemberg <[email protected]>
-
- * src/autofit/afblue.dat: Add more Khmer clusters.
-
- Some fonts have incorrect ligatures; we need more samples to get a
- good mean value.
-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
-
-2015-12-06 Werner Lemberg <[email protected]>
-
- [autofit] Typos.
-

-
- [autofit] Add support for Khmer script.
-
- We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
- `Khmer symbols' (`khms', U+19E0-U+19FF).
-
- * src/autofit/afblue.dat: Add blue zone data for Khmer.
-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
-

-
- * src/autofit/afstyles.h: Add Khmer data.
-
-2015-12-06 Werner Lemberg <[email protected]>
-
- [autofit] Rewrite HarfBuzz interface to support character clusters.
-
- Scripts like Khmer have blue zones that can't be directly
- represented by Unicode characters. Instead, it is necessary to let
- HarfBuzz convert character clusters into proper glyph representation
- forms, then deriving the blue zone information from the resulting
- glyphs.
-
- * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
- * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
- files, providing a new API to access HarfBuzz.
-
- The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
- and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
- string with function `af_shaper_get_cluster', and the resulting
- glyph data (indices, advance widths, vertical offsets) can be
- iteratively accessed with function `af_shaper_get_elem'.
-
- * src/autofit/afcjk.c (af_cjk_metrics_init_widths,
- af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
-
- * src/autofit/aflatin.c (af_latin_metrics_init_widths,

- clusters.
-
- * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
- (AF_ScriptClassRec): Replace `standard_char[123]' with
- `standard_charstring'.

- of the `SCRIPT' calls with a string parameter, holding the standard
- characters (in UTF-8 encoding) separated with spaces.
-

-
- [ftfuzzer] Add support for multiple files (patch #8779).
-
- Currently, libFuzzer only supports mutation of a single file. We
- circumvent this problem by using an uncompressed tar archive as
- multiple-file input for the fuzzer.

- a constructed tarball should contain a font file as the first
- element, and files to be attached as further elements.
-

- [smooth] Faster alternative line renderer.
-
- This implementation renders the entire line segment at once without
- subdividing it into scanlines. The main speed improvement comes from
- reducing the number of divisions to just two per line segment, which

- Notably, the progression from cell to cell does not itself require any
- divisions at all. The speed improvement is more noticeable at larger

- [sfnt] Improve handling of invalid SFNT table entries (#45987).
-
- This patch fixes weaknesses in function `tt_face_load_font_dir'.
-
- - It incorrectly assumed that valid tables are always at the
- beginning. As a consequence, some valid tables after invalid
- entries (which are ignored) were never seen.
-
- - Duplicate table entries (this is, having the same tag) were not
- rejected.
-
- - The number of valid tables was sometimes too large, leading to
- access of invalid tables.
-
- * src/sfnt/ttload.c (check_table_dir): Add argument to return number
- of valid tables.
- Add another tracing message.

-
- [autofit] Redesign code ranges (1/2).
-
- This patch introduces auxiliary code ranges that identify no-base
- characters; they refer to glyphs of a script that should be hinted
- without alignments to blue zones (mostly diacritics).
-
- It also splits off ranges for fallback scripts that handle subscript
- and superscript characters not covered by OpenType features. For
- example, this greatly helps improve the hinting of various phonetic
- alphabets, which contain a large amount characters that look like
- superscript glyphs.
-
- Finally, code ranges are updated to Unicode 8.0, and enclosed
- characters are removed in general since they normally look better if
- they stay unhinted.
-
- * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
- 8.0.
- Split off superscript-like and subscript-like glyphs into...

-
- Fix Savannah bug #45097.
-
- We no longer `pollute' the namespace of possible header file names;
- instead we move `ft2build.h' up by one level so that it gets
- installed in the default include directory (e.g.,
- /usr/local/include). After this commit, only `ft2build.h' stays in
- the compiler's include path.

- No visible changes for the user who follows the standard FreeType
- header inclusion rules.

-
- Problem reported by Grissiom <[email protected]>; in

- http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
-
- there is an example code to trigger the bug.

-2015-05-31 Werner Lemberg <[email protected]>
-
- [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.

-
- [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 <[email protected]>
-
- [truetype] Minor.
-
- * src/truetype/ttinterp.h (TT_ExecContext):

- * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
-
-2015-05-22 Werner Lemberg <[email protected]>
-
- [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 <[email protected]>

- argument.
-
-2015-05-17 Werner Lemberg <[email protected]>
-
- [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 <[email protected]>
-
- [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 <[email protected]>
-
- [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).

-
- [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).

-
- [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'.

-2015-01-14 Behdad Esfahbod <[email protected]>
-
- [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.

- [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 <[email protected]>
-
- [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'.

- [base] Do not reorder library->renderers upon use.

- With this patch, rasterizing glyphs from different faces from
- different threads doesn't fail choosing rasterizer
- (FT_Err_Cannot_Render_Glyph).

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

- using the singleton `TT_ExecContext' that was stored in `TT_Driver'.

+
+2016-07-09 suzuki toshiya <[email protected]>
+
+ [mac] Fix ftexport.sym target in Jamfile.
+
+ * Jamfile: Update the directories of the header files scanned for
+ ftexport.sym. They were incorrect since the migration of the
+ header files, on 2015-06-22. Either inexisting include/cache
+ (removed on 2006-03-20) is not needed to be listed explicitly.
+ Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.
+
+2016-07-08 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Sub-banding protocol revision.
+
+ Rasterization sub-banding is utilized at large sizes while using a
+ rather small fixed memory pool. Indeed it is possible to make an
+ educated guess how much memory is necessary at a given size for a
+ given glyph. It turns out that, for a large majority of European
+ glyphs, you should store about 8 times more boundary pixels than
+ their height. Or, vice versa, if your memory pool can hold 800
+ pixels the band height should be 100 and you should sub-band
+ anything larger than that. Should you still run out of memory,
+ FreeType bisects the band but you have wasted some time. This is
+ what has been implemented in FreeType since the beginning.
+
+ It was overlooked, however, that the top band could grow to twice
+ the default band size leading to unnecessary memory overflows there.
+ This commit fixes that. Now the bands are distributed more evenly
+ and cannot exceed the default size.
+
+ Now the magic number 8 is really suitable for rather simple European
+ scripts. For complex Chinese logograms the magic number should be
+ 13 but that is subject for another day.
+
+ * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
+ protocol.
+
+2016-07-07 suzuki toshiya <[email protected]>
+
+ [mac] Fix Savannah bug #48417.
+
+ Mac OS X linker throws errors when `-exported_symbol_list' input
+ file includes non-existing symbols. Reported by Ryan Schmidt.
+
+ * builds/exports.mk: Exclude ftmac.h from the headers for apinames
+ by default. Include it when ftmac.c would be compiled.
+
+2016-07-06 Werner Lemberg <[email protected]>
+
+ * src/truetype/ttinterp.c (TInstruction_Function): Removed, unused.

+
+2016-07-04 Werner Lemberg <[email protected]>
+
+ [autofit] Handle single-point contours as segments.
+
+ Doing so allows us to link them to edges – some fonts like
+ `NotoSansGurmukhi-Regular' have such isolated points sitting exactly
+ on other outlines.
+
+ * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't

+ af_cyrl_uniranges): Add new data.
+
+2016-07-01 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Variable type revision (part 1).
+
+ This patch restores original `TCoord' definition as `int' so that the
+ rendering pool is used more efficiently on LP64 platforms (unix).
+
+ * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some
+ fields to `TCoord'.
+ (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline,
+ gray_sweep, gray_convert_glyph): Updated.
+
+2016-06-28 Alexei Podtelezhnikov <[email protected]>

+
+2016-06-26 Alexei Podtelezhnikov <[email protected]>
+
+ [pcf] Fix handling of very large fonts (#47708).
+
+ * src/pcf/pcfread.c (pcf_get_encodings): Make `encodingOffset' an
+ unsigned short.
+ Only reject `0xFFFF' as an invalid encoding offset.
+
+2016-06-25 Werner Lemberg <[email protected]>
+
+ [truetype] Really fix deallocation in case of error (#47726).
+
+ * src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize
+ `outline.points' also.
+
+2016-06-23 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Consolidate memory management.

+ (gray_TWorker): Remove fields that become local variables.
+ (gray_raster_render): Move rendering buffer declaration from here.
+ (gray_convert_glyph): ... to here and update accordingly.
+
+2016-06-22 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Consolidate boundary checks.
+
+ Removing the checks from `gray_hline' shaves 1% off rendering speed.
+

+ (gray_convert_glyph): Updated.
+
+2016-06-17 Alexei Podtelezhnikov <[email protected]>
+
+ [raster, smooth] Handle FT_RENDER_POOL_SIZE better.
+
+ * src/raster/ftraster.c (FT_MAX_BLACK_POOL): New macro.
+ (ft_black_render): Updated.

+
+ [cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files.
+
+ * CMakeLists.txt: Each time cmake is run those files are
+ modified and the whole FreeType library is recompiled. With this
+ change we change the files only if there are real modifications, so
+ we can avoid recompilations.
+
+2016-06-09 Werner Lemberg <[email protected]>
+
+ [bdf] Check number of properties (#48166).
+
+ * src/bdf/bdflib.c (_bdf_parse_start): Implement.
+
+2016-06-08 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Re-enable new line renderer on 64-bit archs.

+ implementation, where it is safe from overflows.
+
+2016-06-08 Alexei Podtelezhnikov <[email protected]>
+

+
+2016-06-07 Werner Lemberg <[email protected]>
+
+ [autofit] Fix compilation with VS2016 (#48126).
+
+ This compiler doesn't recognize the end-of-comment sequence `*/' if
+ it immediately follows non-ASCII characters.
+
+ * src/autofit/afscript.h: Ensure whitespace before `*/'.
+
+2016-06-04 Werner Lemberg <[email protected]>
+
+ Fix a test for named instances (#48122).
+
+ This was missed while giving negative face indices an extended
+ meaning.
+
+ * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.
+
+2016-05-31 Nikolaus Waxweiler <[email protected]>
+
+ [truetype] Let SHPIX move points in the twilight zone in v40.
+
+ * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
+ the twilight zone. Otherwise, treat SHPIX the same as DELTAP.
+ Unbreaks various fonts such as older versions of Rokkitt and DTL
+ Argo T Light that would glitch severly after calling ALIGNRP after a
+ blocked SHPIX.
+
+2016-05-30 Werner Lemberg <[email protected]>
+

+
+ * src/type42/t42parse.c (t42_parse_charstrings): Handle entries
+ having the format
+
+ (foo) cvn 12345 def
+
+2016-05-28 Werner Lemberg <[email protected]>
+
+ * src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
+
+ Suggested by Alexei. `UL' is only needed for 16bit compilers, but
+ it seems noone is using this anymore (and we no longer test whether
+ FreeType compiles in such an environment). Otherwise, it is easy to
+ add the postfix to the `AF_UNICODE_RANGE' macro.
+
+2016-05-26 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Shrink bisection stack.
+
+ The convergence of Bézier flatteners is fast with the deviation
+ from straight line being assymptotically cut 4-fold on each bisection.
+ This justifies smaller bisection stack size.
+
+ * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
+ (gray_render_conic): Create and use conic `bez_stack'. Move back the
+ band analysis from...
+ (gray_conic_to): ... here.
+ (gray_render_cubic): Create and use cubic `bez_stack'. Move back the
+ band analysis from...
+ (gray_cubic_to): ... here.
+ (gray_move_to): Updated.
+
+2016-05-25 Werner Lemberg <[email protected]>
+
+ [autofit] Fixes for Armenian and Gujarati ranges.
+
+ * src/autofit/afranges.c (af_armn_uniranges): Corrected.
+ (af_guru_nonbase_uniranges): Make U+0A3E a base character.
+
+2016-05-24 Werner Lemberg <[email protected]>
+
+ [autofit] Add support for Armenian script.
+
+ * src/autofit/afblue.dat: Add blue zone data for Armenian.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Armenian standard characters.
+
+ * src/autofit/afranges.c: Add Armenian data.
+
+ * src/autofit/afstyles.h: Add Armenian data.
+
+2016-05-23 Werner Lemberg <[email protected]>
+
+ * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
+
+ This was commented about 10 years ago – I think the reason then to
+ disable libtool's `-export-symbols' option was to give some badly
+ programmed applications access to internal FreeType functions.
+
+ I believe that we should no longer take care of such programs; the
+ number of symbols exported should be rather restricted as much as
+ possible.
+
+2016-05-22 Werner Lemberg <[email protected]>
+
+ [autofit] Add blue-zone support for Gurmukhi script.
+
+ This essentially moves the Gurmukhi script from the `Indic' hinter to
+ the `Latin' hinter.
+
+ * src/autofit/afblue.dat: Add blue zone data for Gurmukhi.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Gurmukhi standard characters and move
+ data out of AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afranges.c: Move Gurmukhi data out of
+ AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
+ AF_WRITING_SYSTEM_LATIN.
+
+2016-05-21 Werner Lemberg <[email protected]>
+
+ Minor clang++ fixes.
+
+ * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c
+ (ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add
+ initializer.
+
+ * src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit
+ conversion from NULL to boolean.
+
+2016-05-21 Werner Lemberg <[email protected]>
+
+ Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955).
+
+ * include/freetype/internal/ftmemory.h (cplusplus_typeof): Use
+ braces for `extern "C++"'.
+
+2016-05-17 Nikolaus Waxweiler <[email protected]>
+
+ [truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3].
+
+ * src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with...
+ (tt_loader_set_pp): ... this new function.
+ Update all callers.
+
+2016-05-17 Nikolaus Waxweiler <[email protected]>
+
+ [truetype] New implementation of v38 bytecode interpreter [2/3].
+
+ This patch actually modifies the bytecode interpreter.
+
+ See added comments in `ttinterp.h' for more information on this and
+ the following commit in the series.
+
+ * src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by...
+ (NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY,
+ SUBPIXEL_HINTING_MINIMAL): ...new macros.
+ (Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backwards
+ compatibility.
+ Updated.

+
+ [autofit] Add support for Georgian scripts.
+
+ Georgian is problematic, since `uppercase' forms of Mkhedruli
+ (called Mtavruli) are not yet defined in Unicode, which means that
+ proper blue zones can't be defined. However, there is already a
+ proposal submitted to Unicode; see
+
+ http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+
+ Additionally, due to historical reasons, Unicode treats Khutsuri as
+ the same script as Mkhedruli, and so does OpenType. However, since
+ the two scripts have completely different shapes it can happen that
+ blue zones differ considerably. The tag `geok' used here (derived
+ from ISO 15924) to differentiate the two scripts is not an OpenType
+ tag in use. If we now have a font that contains both glyphs for
+ Mkhedruli and Khutsuri, and it uses OpenType features for both also,
+ HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
+ blue zones for `geok' are not used for glyphs involved in the
+ OpenType features.
+
+ An issue not yet resolved is which OpenType feature should be used
+ to access Mtavruli glyph shapes; right now, FreeType doesn't set up
+ support for them, but it is easy to add them later on as soon as
+ more information is available.

+
+ [autofit] Fix handling of default script.
+
+ Patch taken from ttfautohint, commit
+ 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
+
+ There were two bugs.
+
+ - We now use non-standard script tags like `khms' for special
+ purposes. However, HarfBuzz maps such tags to `DFLT', and
+ without this commit the associated lookups were incorrectly
+ assigned to the non-standard tags.
+
+ - Let's assume we have a Bengali font, and the font's `DFLT'
+ script tag handles the necessary lookups for Bengali, too.
+ Without this commit, the `DFLT' lookups were assigned to
+ ttfautohint's default script (usually `latn') before the
+ standard lookups for Bengali were handled.
+
+ We now have the following order while searching for covered
+ glyph indices.
+
+ special features of scripts (e.g. `sups' for Cyrillic)
+ Unicode mappings of scripts
+ remaining features of scripts (especially important for Indic
+ scripts)
+ default features of default script

+ (af_shaper_get_coverage): Add boolean parameter to indicate default
+ script.

+2015-12-10 Werner Lemberg <[email protected]>
+
+ [autofit] Remove redundant code.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_widths): Do it.
+
+2015-12-09 Werner Lemberg <[email protected]>
+
+ [autofit] Thinko.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count
+ empty blue zones (bug introduced 2015-12-06).
+
+2015-12-09 Werner Lemberg <[email protected]>
+
+ [autofit] Introduce subscript top blue zones.
+
+ This feature is mainly for Khmer: The idea is to avoid a clash
+ between the top of subscript glyphs and the bottom of normal
+ baseline glyphs.
+
+ This only works for character clusters mapped to multiple glyphs.
+
+ * src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
+
+ * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
+ macro.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE,
+ AF_LATIN_BLUE_SUB_TOP): New macros.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new
+ blue zone property.
+ Update tracing messages.
+ (af_latin_metrics_scale_dim): Handle new blue zone property.

+
+2015-12-09 Werner Lemberg <[email protected]>
+
+ [autofit] Fix tracing message.
+
+ * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Display
+ inactive blue zones also.
+
+2015-12-06 Werner Lemberg <[email protected]>
+
+ * src/autofit/afblue.dat: Add more Khmer clusters.
+
+ Some fonts have incorrect ligatures; we need more samples to get a
+ good mean value.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+2015-12-06 Werner Lemberg <[email protected]>
+
+ [autofit] Typos.
+

+
+2015-12-06 Werner Lemberg <[email protected]>
+
+ [autofit] Add support for Khmer script.
+
+ We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
+ `Khmer symbols' (`khms', U+19E0-U+19FF).
+
+ * src/autofit/afblue.dat: Add blue zone data for Khmer.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Khmer standard characters.
+
+ * src/autofit/afranges.c: Add Khmer data.
+
+ * src/autofit/afstyles.h: Add Khmer data.
+
+2015-12-06 Werner Lemberg <[email protected]>
+
+ [autofit] Rewrite HarfBuzz interface to support character clusters.
+
+ Scripts like Khmer have blue zones that can't be directly
+ represented by Unicode characters. Instead, it is necessary to let
+ HarfBuzz convert character clusters into proper glyph representation
+ forms, then deriving the blue zone information from the resulting
+ glyphs.
+
+ * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
+ * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
+ files, providing a new API to access HarfBuzz.
+
+ The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
+ and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
+ string with function `af_shaper_get_cluster', and the resulting
+ glyph data (indices, advance widths, vertical offsets) can be
+ iteratively accessed with function `af_shaper_get_elem'.
+
+ * src/autofit/afcjk.c (af_cjk_metrics_init_widths,
+ af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_widths,

+
+ This makes it easier to control the commits.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy
+ loop. No functional change.
+
+2015-12-06 Werner Lemberg <[email protected]>
+
+ [autofit] Use string of standard characters.
+
+ This is more flexible; additionally, it would allow character
+ clusters.
+
+ * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
+ (AF_ScriptClassRec): Replace `standard_char[123]' with
+ `standard_charstring'.
+
+ * src/autofit/afscript.h: Replace last three character arguments
+ of the `SCRIPT' calls with a string parameter, holding the standard
+ characters (in UTF-8 encoding) separated with spaces.
+
+ * src/autofit/afglobal.c, src/autofit/afglobal.h,
+ src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c

+
+2015-12-05 Werner Lemberg <[email protected]>
+
+ * src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces.

+ [ftfuzzer] Add support for multiple files (patch #8779).
+
+ Currently, libFuzzer only supports mutation of a single file. We

+ [sfnt] Improve handling of invalid SFNT table entries (#45987).
+
+ This patch fixes weaknesses in function `tt_face_load_font_dir'.
+
+ - It incorrectly assumed that valid tables are always at the
+ beginning. As a consequence, some valid tables after invalid
+ entries (which are ignored) were never seen.
+
+ - Duplicate table entries (this is, having the same tag) were not
+ rejected.
+
+ - The number of valid tables was sometimes too large, leading to
+ access of invalid tables.

+ * src/sfnt/ttload.c (check_table_dir): Add argument to return number
+ of valid tables.
+ Add another tracing message.
+ (tt_face_load_font_dir): Only allocate table array for valid
+ entries as returned by `check_table_dir'.

+ [autofit] Redesign code ranges (1/2).
+
+ This patch introduces auxiliary code ranges that identify no-base
+ characters; they refer to glyphs of a script that should be hinted
+ without alignments to blue zones (mostly diacritics).
+
+ It also splits off ranges for fallback scripts that handle subscript
+ and superscript characters not covered by OpenType features. For
+ example, this greatly helps improve the hinting of various phonetic
+ alphabets, which contain a large amount characters that look like
+ superscript glyphs.
+
+ Finally, code ranges are updated to Unicode 8.0, and enclosed
+ characters are removed in general since they normally look better if
+ they stay unhinted.

+ * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode

+ [truetype] In GX, make private point numbers work correctly.
+
+ This is completely missing in Apple's documentation: If a `gvar'

+ 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

+ Add tracing information.
+ Call `tt_handle_deltas' to interpolate missing deltas.
+ Also fix a minor memory leak in case of error.

+2015-05-17 Werner Lemberg <[email protected]>
+
+ [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 <[email protected]>
+
+ [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 <[email protected]>
+
+ [cff] fix incremental interface with new cff code.
+
+ * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental

+ incremental interface callback to apply the encoding to raw
+ character index (as it was in the previous code).

+
+ Add fallback for glyphs with degenerate bounding boxes.
+
+ If a glyph has only one very narrow feature, the bbox can end up

+ No need to create a new glyph loader; we can reuse the one from

+
+ [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.

+
+ [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 <[email protected]>
+
+ [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'.
