Khaled Hosny 0cd7d041d8 [appveyor] Don’t build branches with open PR twice 2018-10-24 17:27:28 +02:00
Behdad Esfahbod 401cdf0792 [ot-font] Fix sign of ascent/descent 
Some fonts, like msmincho, have positive number as descent
in vhea table.  That's wrong.  Just enforce sign on ascent/descent
when reading both horizontal and vertical metrics.

Behdad Esfahbod ffe3478448 [aat] Allow enabling/disabling features 
Only works at entire-buffer range, not sub-ranges.

Test with:

$ hb-shape Zapfino.dfont Zapfino

$ hb-shape Zapfino.dfont Zapfino --features=-dlig
[Z=0+416|a=1@-21,0+264|p_f=2+433|i=4+181|n=5+261|o=6+250]

$ hb-shape Zapfino.dfont Zapfino --features=+dlig

So '--features=-trak' or 'font-feature-settings: 'trak' 0;' can prevent
applying of tracking if used.

Behdad Esfahbod 792071de40 [morx] Leave ligature on stack after ligating 
Test with Apple Color Emoji.ttf of ~66MB and following sequence:

./hb-shape Apple\ Color\ Emoji-old.ttf --font-funcs=ot -u U+1F468,200d,U+1F469,200d,U+1F467,200d,1f466

Should form full family if matching works correctly.  It first makes
family of three, then makes family of four out of that and the last
two characters.

[ci] Disable llvm-gcc 
#define Null(Type) Null<typename hb_remove_const<typename hb_remove_reference<Type>::value>::value>()

raises:
  hb-blob.cc: In function 'hb_blob_t* hb_blob_get_empty()':
  hb-blob.cc:194: error: using 'typename' outside of template
  hb-blob.cc:194: error: using 'typename' outside of template

Removing "typename"s fixes the issue but makes newer compiler fail apparently.

Probably downstream can patch that locally till we get a solution.

Behdad Esfahbod b18acab7bc [color] Add HB_COLOR 
Normally I would have added to_string / from_string like other types
have.  But since we don't use hb_color_t much, I'm not going to do that.
Although, if we did, we could use it in hb-view to parse colors...

Behdad Esfahbod f3336580dd [color] Use hb_array_t in CPAL 
Doesn't work though, ouch :(.  Need to figure out if it's unreasonable

of Null for NameID.

Behdad Esfahbod 3bf91bd269 [color] Rewrite colr access 
COLR table has one function: return layers for a glyph, and we expose exactly
that, so should just wire it through.  Also use sub_array() for verifiable
safety.

Also, BaseGlyphRecord's null object is enough.  We don't need to special-case
the not-found.
