Werner Lemberg 0164d934b6 [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.

good mean value.

* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
2015-12-08 09:48:50 +01:00

Werner Lemberg facb79abdc [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.

2015-12-06 19:34:59 +01:00
Werner Lemberg 24aa9c665e [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/.

(AF_ScriptClassRec): Replace `standard_char[123]' with
`standard_charstring'.

characters (in UTF-8 encoding) separated with spaces.
