77930974	2017-03-07T17:27:58	[sfnt] Improve handling for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=738 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `glyf' present also (which gets priority).
27fee7f8	2017-03-06T20:45:44	[sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances.

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.
fcd47b3d	2017-02-12T23:07:29	* src/smooth/ftgrays.c (gray_sweep): Improve code.
faa3c882	2017-02-06T13:13:02	[truetype] Implement `VVAR' table support. * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... (GX_HVVarTable): ...This.

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.

fa437d8d	2017-01-31T23:06:38	[cff] Provide metrics variation service interface (#50196). Only now I've got an OTF with an HVAR table for testing... The code in `ftmm.c' uses `FT_FACE_LOOKUP_SERVICE' to get the metrics variations interface. However, this didn't work with `FT_FACE_FIND_GLOBAL_SERVICE' used in `sfnt_init_face'. * src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H.

[sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances.

[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.

[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.
