Khaled Hosny	6cf308c857	[test/shape] Remove @font-funcs-=directwrite from directwrite test ... The directwrite font functions support variations now, so this is no longer needed.	2025-03-25 10:34:43 +02:00

Behdad Esfahbod	2a878b1b76	[font-funcs] Add two new API ... + hb_font_set_funcs_using() + hb_font_list_funcs() Part of https://github.com/harfbuzz/harfbuzz/issues/5117	2025-03-08 11:50:53 -07:00
Khaled Hosny	a356603061	[directwrite/test] Add test that actually works ... Apparently DirectWrite does not allow disabling calt in Arabic, so test liga in Latin and ss01 in Arabic.	2025-03-07 14:30:53 +02:00
Khaled Hosny	9abaf193d3	[directwrite] Fix applying features to directwrite shaper ... The range_features was ending up with random data because hb_ms_make_feature_ranges() keeps pointers to data allocated in feature_records and range_records, but that data was getting freed before range_features was used. Change the variable scope to avoid freeing the data too early. Fixes https://github.com/harfbuzz/harfbuzz/issues/5113	2025-03-07 14:30:53 +02:00
Behdad Esfahbod	be287eab02	[trak] Don't shift glyphs ... That's what CoreText does and fonts are designed for. Who are we to improve on...	2025-02-09 04:19:02 +00:00
Behdad Esfahbod	1150d4bf12	[trak] Remove support for disabling using pseudo-font-feature ... Fixes https://github.com/harfbuzz/harfbuzz/issues/5052	2025-02-09 04:16:57 +00:00

Behdad Esfahbod	b1677e76aa	[trak] Handle "out-of-range" values better ... If requested size < min-size, use the value for min-size. If requested size > max-size, use the value for max-size. This is the only way that makes sense. Extrapolating as we were doing, is just wrong... This also seems to match what CoreText does.

Khaled Hosny	773fe85018	[layout] Blocklist the GDEF table of various Courier New versions ... These files have incorrectly give several base glyphs GDEF mark glyph class leading in zeroing there advance widths. Fixes https://github.com/harfbuzz/harfbuzz/issues/4936	2024-11-21 14:40:57 -07:00
Behdad Esfahbod	2dc6334133	[tests] Remove invalid tests from collections.tests ... Previously we silently returned the empty face if face_index was out of range. With util/ now using the new API hb_font_face_create_from_file_or_fail(), that returns a nullptr face now. So, adjust tests.	2024-10-15 14:58:13 -06:00
David Corbett	b6196986d7	[USE] Update the data files ... This uses the data files from <e00698c07a/USE>.	2024-10-03 19:54:54 -06:00

Behdad Esfahbod	5e5cd10e10	Don't make variation-selectors default-ignorable if not-found set ... https://github.com/harfbuzz/harfbuzz/pull/4863#issuecomment-2366908261	2024-09-23 06:30:59 -06:00
Behdad Esfahbod	b94a39d7f3	Follow up to variation-selector-not-found glyph ... Addresses https://github.com/harfbuzz/harfbuzz/pull/4529#discussion_r1769638033 I'm not sure if this is an improvement. By leaving the var-selector as default-ignorable, ligatures can form around it, and the resulting cluster won't make it clear *which* base+var-selector could not be resolved... That doesn't quite help font fallback the way we want. Putting up for review.	2024-09-23 06:30:59 -06:00
Behdad Esfahbod	287046f71a	[buffer] Hook up not-found-variation-selector-glyph ... Fixes https://github.com/harfbuzz/harfbuzz/issues/4398	2024-09-21 12:21:56 -06:00
