Khaled Hosny 46e3882f 2025-10-23T02:11:13 [subset] Don’t collect name IDs from STAT table if it is dropped (#5623)
Behdad Esfahbod 82370913 2025-09-15T20:16:52 [vector] Simplify resize()
Garret Rieger aa58b43d 2025-09-12T14:24:41 [subset] Introduce HB_SUBSET_FLAGS_RETAIN_NUM_GLYPHS. (#5547) Used in conjunction with retain gids, when set the num glyphs from the input font will be preserved. Empty glyphs will be inserted as necessary to maintain the num glyphs value. Put under experimental for now.
Behdad Esfahbod 47089fe7 2025-05-28T17:10:22 Big misc changes - Make geometry types into templates taking float or double. - Changes to paint() transform elimination. - Add font->has_nonzero_coords and use it across. - Extensions to avar processing for otherwise invalid mappings.
Behdad Esfahbod aef3df50 2025-04-20T00:37:24 Merge branch 'main' into HVF
Garret Rieger efcb7d3d 2025-04-11T23:34:06 [subset] close unicodes over bidi mirror variants during subsetting. Fixes #5281. Does the closure by default, but I've introduced a new flag and option to disable this behaviour since some users may want to get the minimal set if they know they don't need the mirrored variants.

Garret Rieger 5afbd187 2025-04-09T22:48:27 [subset] Split subset plan variations function into separate file. Compile times for hb-subset-plan.cc go from 16s -> 13s.
Garret Rieger d3ccdcdd 2025-04-09T22:26:59 [subset] Move GDEF subset planning into hb-subset-plan-layout.cc
Garret Rieger b33f2e26 2025-04-09T22:11:12 [subset] Start splitting layout specific subset plan functionality. The aim is to reduce the compiled time of hb-subset-plan.cc which on my machine takes almost 30s to compile.

Behdad Esfahbod 9cae040b 2025-04-03T22:18:14 [ItemVariationStore] Make cache atomic floats Doesn't work with intrinsic atomic implementations. Disabled that. Going through the C++11 atomics path now. Will fix in next commit.
Behdad Esfahbod 19b4c6e5 2025-02-25T13:39:59 [subset] "Fix" subset tests after recent fvar/avar precision changes
Behdad Esfahbod d7b15b0e 2025-02-08T21:14:59 [font/fvar/avar] Increase axis coordinate normalization precision Spec requires 16.16; we were doing 2.14. Fix up. Now we do math in float, but do the 16.16 and final 2.14 rounding as required by the spec.
Garret Rieger b0d52abe 2024-10-23T20:49:44 [subset] consider variation selectors subsetting cmap14 cmap14 subsetting code was not considering variation selectors in the input unicode set when deciding which variant glyphs to keep. This updates subsetting to only keeps variant glyphs if their variation selector code point is in the input unicodes set. For https://github.com/harfbuzz/harfbuzz/issues/4911

Behdad Esfahbod 2b5af6f4 2023-11-10T15:23:27 [subset-plan] Micro-optimize set iteration Getting ranges is faster even with the current trivial implementation.
Behdad Esfahbod 6d3b7931 2023-11-10T14:51:34 [subset-plan] Add a couple of allocs
Garret Rieger c6884377 2023-11-06T20:21:46 [subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2. This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.
