1dee4bf9 | 2017-02-05 08:33:10 | [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. | |

aafff574 | 2016-07-16 06:41:39 | * 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 | 2016-07-15 10:35:32 | [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. | |

(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 | 2016-07-04 14:59:22 | [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. | |

15eab363 | 2016-06-07 10:36:27 | [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 | 2016-05-28 19:38:43 | * 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. | |

c8c7ad79 | 2016-04-09 08:24:00 | [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. | |

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. | |

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

|
0164d934 | 2015-12-09 20:04:18 | [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. (af_latin_hints_compute_blue_edges): Updated. | |

|
facb79ab | 2015-12-06 19:34:59 | [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 | 2015-12-06 18:52:41 | [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. | |

|
f45c0bf9 | 2015-12-06 09:58:18 | [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 (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated. | |

|
68fb4789 | 2015-11-15 13:06:48 | * src/autofit/afhints.c (af_get_segment_index): Fix it. The old code was too simple, returning invalid values in most cases where a segment crosses the contour start. | |
|
75722f89 | 2015-11-11 09:55:16 | [cff, autofit] Switch off stem darkening by default. * src/autofit/afmodule.c (af_autofitter_init), src/cff/cffobjs.c (cff_driver_init): Do it. | |

|
bf2ba9e3 | 2015-11-02 13:12:34 | [autofit] Implement darkening computation function. This is a crude adaption of the original `cf2_computeDarkening' function. * src/autofit/afloader.c (af_intToFixed, af_fixedToInt, af_floatToFixed): New macros, taken from `cf2fixed.h'. (af_loader_compute_darkening): New function. * src/autofit/afloader.h: Updated. | |
|
37c401ac | 2015-11-02 09:32:26 | [autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation.
