Werner Lemberg fb672897 2016-01-20T21:13:16 [autofix] Complete last autofit commit. Problem reported by Kostya Serebryany <kcc@google.com>. * src/autofit/afshaper.c (af_shaper_get_coverage) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Update signature.
Werner Lemberg 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. Update all callers. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Fix search order for coverages.

Werner Lemberg b0de5a82 2015-12-23T23:25:03 [autofit] Start implementing hinting direction (up/down, down/up). Right now, it does nothing. * src/autofit/afscript.h: Add another parameter to `SCRIPT', specifying hinting direction. * src/autofit/afglobal.c, scr/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/afshaper.c, src/autofit/aftypes.h: Extend `SCRIPT' definitions.
Werner Lemberg 4fe3b55d 2015-12-11T08:08:48 [autofit] Restore OpenType feature check. This was removed while rewriting the HarfBuzz interface. * src/autofit/afglobal.h (AF_FaceGlobalsRec): Add `hb_buf' field to hold internal HarfBuzz buffer, needed for feature comparison. * src/autofit/afglobal.c (af_face_globals_new, af_face_globals_free): Initialize and destroy `hb_buf'. * src/autofit/afshaper.c (af_shaper_get_cluster): Compare character (cluster) with and without applied feature. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix tracing message.
Werner Lemberg 3c3d7c21 2015-12-10T11:54:41 Another typo.
Werner Lemberg 93fdf4eb 2015-12-10T11:52:08 Formatting.
Werner Lemberg 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.
Werner Lemberg 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/. (af_face_globals_compute_style_coverage): Updated. * src/autofit/afglocal.h: s/hbshim.h/afshaper.h/. * src/autofit/autofit.c: s/hbshim.c/afshaper.c/. * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC): Updated.
