Werner Lemberg ba40054c 2017-05-02T12:32:19 [autofit] Remove `slight' auto-hint mode again. A poll on freetype-devel favoured changes directly applied to `light'. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT, FT_RENDER_MODE_SLIGHT): Removed. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init): Revert change from 2017-04-22. * src/autofit/afloader.c (af_loader_load_glyph) Remove references to FT_RENDER_MODE_SLIGHT. [AF_CONFIG_OPTION_TT_SIZE_METRICS]: Enable TrueType-like metrics unconditionally. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Revert change from 2017-04-22. * src/base/ftobjs.c (FT_Load_Glyph): Revert change from 2017-04-22. * src/pshinter/pshalgo.c (ps_hints_apply): Revert change from 2017-04-22. * src/smooth/ftsmooth.c (ft_smooth_render): Revert change from 2017-04-22. * docs/CHANGES: Updated.
Werner Lemberg 0a5315d1 2017-04-27T13:02:24 Introduce AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option. * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_TT_SIZE_METRICS): New option, commented out by default. * src/autofit/afloader.c (af_loader_load_glyph): Use AF_CONFIG_OPTION_TT_SIZE_METRICS to guard the corresponding code.
Werner Lemberg 5aa6716a 2017-04-22T13:27:21 Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. (FT_RENDER_MODE_SLIGHT): New render mode. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add `autohint_mode' and `autohint_metrics' fields. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): Updated. * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use `autohint_metrics'. (af_loader_load_glyph): s/internal/slot_internal/. Initialize `autohint_metrics' and `autohint_mode' depending on current auto-hint mode. Use `autohint_metrics'. Updated. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. * src/base/ftobjs.c (FT_Load_Glyph): Updated. (FT_New_Size): Allocate `internal' object. * src/pshinter/pshalgo.c (ps_hints_apply): Updated. * src/smooth/ftsmooth.c (ft_smooth_render): Updated.

Werner Lemberg 319125d4 2017-02-13T09:34:17 [autofit] Prevent overlapping blue zones. Problem reported as https://github.com/google/fonts/issues/632 The font in question (Nunito) has values 705 and 713 for the reference and overshoot values, respectively, of the first blue zone. Blue zone 2, however, has value 710 for both the reference and overshoot. At 12ppem, reference and overshoot of blue zone 0 becomes 8px, while blue zone 2 becomes 9px. A peculiarity of this font is that the tops of isolated vertical stems like `N' have a slight overshoot also. The auto-hinter tries to find the nearest blue zone using the *original* coordinates. For vertical stems, this is value 713. For normal horizontal tops like in character `E', this is value 710. Since value 713 is mapped to 8px but value 710 to 9px, `N' and similar characters are one pixel higher than `E', which looks very bad. This commit sanitizes blue zones to avoid such a behaviour. * src/autofit/aflatin.c (af_latin_sort_blue): New function. (af_latin_metrics_init_blues): Sort blue values and remove overlaps.
Werner Lemberg 1dee4bf9 2017-02-05T08:33:10 [autofit] Use better blue zone characters for lowercase latin. The number of lowercase characters for computing the top flat blue zone value was too small (in most cases only `x' and `z'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights. Problem reported by Christoph Koeberlin <christoph@koe.berlin>. * src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced with... (AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM): ... New, extended sets. (AF_BLUE_STRINGSET_LATN): Updated. * src/autofit/afblue.c, scr/autofit/afblue.h: Regenerated.

Werner Lemberg dadc50a4 2017-02-02T07:13:29 Make compilation with FT_CONFIG_OPTION_PIC work again. All code committed here is guarded with `FT_CONFIG_OPTION_PIC'. * include/freetype/internal/services/svmetric.h (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Remove trailing semicolon. * src/autofit/aflatin.c (af_latin_hints_compute_edges, af_latin_hint_edges): Provide `globals' variable. * src/autofit/afloader.c (af_loader_load_glyph): Remove shadowing variable. * src/autofit/afmodule.c (AF_SCRIPT_CLASSES_GET, AF_STYLE_CLASSES_GET): Redefine. * src/autofit/aftypes.h (AF_DEFINE_WRITING_SYSTEM_CLASS): Fix typo. * src/cff/cffparse.c (CFF_FIELD_BLEND): Provide it. * src/cff/cffpic.h (CffModulePIC): Fix typo.

Werner Lemberg 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.
Oleksandr Chekhovskyi 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.
Nikolaus Waxweiler 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.
Werner Lemberg 48c77da3 2016-11-17T07:37:50 Add minor comment to avoid confusion (#19044).
Werner Lemberg 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.
Werner Lemberg c95b7652 2016-09-17T17:12:50 s/0/NULL/ for function pointers; comments, formatting.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg d9c7f5aa 2016-07-26T20:20:27 * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor. No functional change.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.

Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 05a55a56 2016-06-13T12:16:45 [autofit] Add support for Cherokee script. * src/autofit/afblue.dat: Add blue zone data for Cherokee. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Cherokee standard characters. * src/autofit/afranges.c: Add Cherokee data. * src/autofit/afstyles.h: Add Cherokee data.

Werner Lemberg 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 `*/'.
Werner Lemberg 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.
Werner Lemberg 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.

Werner Lemberg 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.

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.
