563ae780	2017-01-04T20:16:34	Update copyright year.
84b0d992	2016-12-29T10:38:51	/: Use `0.5f' for tracing 16.16 numbers.
4441f7b2	2016-12-26T17:08:17	Replace `foo == NULL' and `foo != NULL' with `!foo' and `foo', resp. Other minor formatting.
d44daf9e	2016-12-21T23:03:48	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. Don't apply deltas twice for non-phantom points. Spotted by Ben Wagner.
255828c8	2016-12-01T07:07:22	[autofit] Fix Emscripten crash (patch #9180). Function calls through pointers must use a matching signature to work on Emscripten, since such calls are dispatched through lookup tables grouped by signature. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Fix typedef.
b37b799c	2016-11-27T16:30:53	[autofit] Code shuffling. Also improve some comments and remove unused code. No functional change. * src/autofit/afloader.c (af_loader_load_g): Merged with... (af_loader_load_glyph): ...this function. Split off emboldening code into... (af_loader_embolden_glyph_in_slot): ... this function.
48c77da3	2016-11-17T07:37:50	Add minor comment to avoid confusion (#19044).
2f2e73c5	2016-09-24T22:42:58	[autofit] Tracing fixes. * src/autofit/afmodule.c (af_autofitter_load_glyph): Call dumping functions only if we actually do tracing.
c95b7652	2016-09-17T17:12:50	s/0/NULL/ for function pointers; comments, formatting.
9749f269	2016-09-08T07:51:03	[autofit] Another improvement to Armenian support. Suggested by Hrant H Papazian <hpapazian@gmail.com>. * src/autofit/afscript.h: Use better suited characters to derive default stem widths.
c9adf1a1	2016-09-05T07:32:37	[autofit] Improve Armenian support. Thanks to Hrant H Papazian <hpapazian@gmail.com> for help. * src/autofit/afblue.dat (AF_BLUE_STRING_ARMENIAN_): Improve selection of characters. src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
d9c7f5aa	2016-07-26T20:20:27	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor. No functional change.
aafff574	2016-07-16T06:41:39	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko. `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed. Reported by Alexei.
1831e6f0	2016-07-15T10:35:32	[autofit] Update and improve segment and edge tracing. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace `delta' also. Don't show first point of segment as a replacement for `pos'; this is (a) misleading, since the difference to `pos' can be almost arbitrarily large in corner cases, and (b) it is better to have all segment data in font units instead of a single value given in output space coordinates. Improve layout. (af_glyph_hints_dump_edges): Show px->units and units->px conversion values for convenience. Improve layout.
894c0228	2016-07-15T10:23:11	[autofit] For edges, reject segments wider than 1px (#41334). * src/autofit/afhints.h (AF_SegmentRec): New member `delta'. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute `delta'. (af_latin_hints_compute_edges): Reject segments with a delta larger than 0.5px.
605946af	2016-07-11T16:14:36	Conditionally compile environment support. * include/freetype/internal/ftobjs.h, src/autofit/afmodule.c, src/base/ftobjs.c, src/cff/cffdrivr.c, src/truetype/ttdriver.c: Decorate with `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' where necessary.
8f8ae8c5	2016-07-11T15:11:38	Handle properties in `FREETYPE_PROPERTIES' environment variable. This commit covers the most important one. * src/autofit/afmodule.c (af_property_set): Handle `warping', `darkening-parameters', and `no-stem-darkening'. * src/cff/cffdrivr.c (cff_property_set): Handle `darkening-parameters', `hinting-engine', and `no-stem-darkening'. * src/truetype/ttdriver.c (tt_property_set): Handle `interpreter-version'.
c3beb30a	2016-07-10T07:11:45	Add function `ft_property_string_set'. This is a preparation for handling an `FREETYPE_PROPERTIES' environment variable to control (some) driver properties. No change in functionality. * src/base/ftobjs.c (ft_property_do): Add `value_is_string' parameter. (ft_property_string_set): New function. (FT_Property_Set, FT_Property_Get): Updated. * include/freetype/internal/ftobjs.h: Updated. * include/freetype/internal/services/svprop.h (FT_Properties_SetFunc): Add `value_is_string' parameter. * src/autofit/afmodule.c (af_property_set), src/cff/cffdrivr.c (cff_property_set), src/truetype/ttdriver.c (tt_property_set): Updated, emitting an error currently if `value_is_string' is set.
5e353f07	2016-07-04T14:59:22	[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 ignore one-point contours but handle them specially as one-point segments. (af_latin_hints_compute_edges): Append one-point segments to edges if possible.
8b8c4408	2016-07-02T18:35:50	[autofit] Remove unused structure members. * src/autofit/afhints.h (AF_SegmentRec, AF_EdgeRec): Remove `num_linked'. * src/autofit/afcjk.c (af_cjk_hints_link_segments): Updated.
aab2b8d8	2016-07-02T08:37:44	[autofit] Update to Unicode 9.0.0. * src/autofit/afranges.c (af_arab_nonbase_uniranges, af_cyrl_uniranges): Add new data.

15eab363	2016-06-07T10:36:27	[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 `*/'.
46d36904	2016-05-28T19:38:43	* 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.
e97918c5	2016-05-25T07:13:29	[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.

80afef8b	2016-04-23T21:34:15	[autofit] Improve Georgian blue zone characters. Suggested by Akaki Razmadze <razmadzekoko@gmail.com>. * src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM): Updated. * src/autofit/afblue.c: Regenerated.
c8c7ad79	2016-04-09T08:24:00	[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. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data.

bf8f100d	2016-04-05T11:43:58	[autofit] Provide dummy blue zone for pseudo script `none'. Even if the dummy hinter is used as the handler for `none' (which doesn't use blue zones), it is more consistent than the old value (which was 0), pointing to Arabic... * src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE.

614a8f17	2016-03-21T19:39:14	* src/autofit/afhints.c (af_glyph_hints_reload): Thinko. This fixes the previous commit to this file.
709486db	2016-03-20T22:20:32	[autofit] Show `near' points in tracing. * src/autofit/afhints.h (AF_FLAG_NEAR): New macro. * src/autofit/afhints.c (af_glyph_hints_dump_points): Implement it. (af_glyph_hints_reload): Handle AF_FLAG_NEAR.
da86b73f	2016-03-15T07:55:05	* src/autofit/aflatin.c (af_latin_compute_stem_width): Optimize.
caa48b0d	2016-03-05T19:47:07	[autofit] Avoid excessive stem length rounding (#25392). * src/autofit/aflatin.c (af_latin_compute_stem_width): Add argument to pass difference between hinted and unhinted position of base point; use this to adjust the stem width depending on the PPEM so that it doesn't become too large under certain circumstances. Update all callers using value 0 for this argument except... (af_latin_align_linked_edge): Pass position delta of base point to `af_latin_compute_stem_width'.
3eb6f66a	2016-03-01T07:10:30	[autofit] Fix reallocation error introduced in 2016-02-27 (#47310). * src/autofit/aflatin.c (af_latin_hints_compute_segments): Reassign `prev_segment' after reallocation.
015c6e08	2016-03-01T06:45:52	Fix clang warnings. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Use FT_UShort for `min_flags' and `max_flags'.

f2169478	2016-02-28T22:48:34	[autofit] Properly handle spikes pointing to the x-axis. An example that gets better rendered is glyph `uusignTaml' (glyph index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly handle segments where the last point of the first segment is identical to the first point in the second one. This can happen for malformed fonts or spikes. We either merge the new segment with the previous one (both segments point into the same direction), or we discard the shorter segment if they point into different directions.
ce486645	2016-02-27T15:01:49	[autofit] Minor code clean-up. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Change some local variable names to better differentiate between values along a segment and values orthogonal to it.
ebfd7ce5	2016-02-26T08:10:41	[autofit] Improve BOUND action. In complex glyph shapes, the original logic was too simple to cater for situations that would actually need something similar to PS Hint masks. This fix should alleviate the worst cases. * src/autofit/aflatin.c (af_latin_hint_edges): Don't allow complete disappearance of stems.
44324b37	2016-02-25T06:58:47	[autofit] Add blue-zone support for Tamil script.

a5952d30	2016-02-18T12:56:38	[autofit] Add blue-zone support for Malayalam script. This essentially moves the Malayalam script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Malayalam. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Malayalam standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Malayalam data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Malayalam data; in particular, use AF_WRITING_SYSTEM_LATIN.

ec776596	2016-01-19T19:33:57	[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.

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. (af_latin_hints_compute_blue_edges): Updated.
f02e1df7	2015-12-09T14:45:30	[autofit] Fix tracing message. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Display inactive blue zones also.
c13526e6	2015-12-08T09:48:50	* 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.
b38ca3cb	2015-12-06T19:48:31	[autofit] Typos. * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_get_elem) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Make it compile.
facb79ab	2015-12-06T19:34:59	[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.
24aa9c66	2015-12-06T18:52:41	[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, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.

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 (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.

(af_loader_compute_darkening): New function. * src/autofit/afloader.h: Updated.
37c401ac	2015-11-02T09:32:26	[autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type.

[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. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data.

[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.

[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, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.
