Garret Rieger 071aea42c2 [iter] add specialized implementation for hb_concat forward when iterators are not random access. 2021-12-01 08:37:04 -07:00
Garret Rieger 2e935514d9 [iter] fix forward implementation in hb_concat().
Add test coverage for forward.

Garret Rieger 9121ed0cec [subset] Improve sharing of Ligature subtables.
Ligature subtables use virtual links to enforce an ordering constraint between the subtables and the coverage table. Unfortunately this has the sideeffect of prevent the subtables from being shared by another Ligature with a different coverage table since object equality compares all links real and virtual. This change makes virtual links stored separately from real links and updates the equality check to only check real links. If an object is de-duped any virtual links it has are merged into the object that replaces it.

Garret Rieger 599143824c [subset] Don't pad glyphs when using long loca. 2021-11-26 18:01:04 -07:00
Garret Rieger d9660fd58a [subset] Make cmap4 packing more optimal.
The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.

Qunxin Liu 364b6b3989 [subset] Don't assume FeatureList is sorted
Though the spec said FeatureRecords are sorted alphabetically by feature
tag, there're font files with unsorted FeatureList. And harfbuzz is not
able to subset these files correctly because we use binary search in
finding featureRecords when collecting lookups. Also
find_duplicate_features needs to be updated to handle this.

Garret Rieger 49c9392412 [subset] During LigatureSubstFormat1 subsetting always place Coverage last.
In Windows 7 on Chrome if the coverage table comes before any of the LigatureSet or Ligature subtables the font won't load. This changes the packing order to always place the Coverage table last. Virtual links are used to ensure the repacker maintains the desired ordering.

Coincidentally fontTools also does the same thing (a3f988fbf6/Lib/fontTools/ttLib/tables/otTables.py (L1137)) to reduce overflows during packing.
