Behdad Esfahbod 166e7024 2025-07-20T13:57:33 [font] Fix glyph_v_origin copy/pasta Ouch!
Behdad Esfahbod 62546424 2025-07-19T14:44:00 [font] Speed up non-synthetic v-origins
Behdad Esfahbod 4fd6345a 2025-07-19T14:42:40 [ot-font] Clean up cache invalidation Also, cache is_synthetic on font.
Behdad Esfahbod faa4472d 2025-07-19T03:12:19 [ot-shape] Use batch origin-changing callbacks Backends don't implement it yet.
Behdad Esfahbod 7d3f8ced 2025-07-19T02:53:03 [font] Minor refactor
Behdad Esfahbod 1835c088 2025-07-19T02:25:43 [font] Add get_glyph_[hv]_origins callbacks (plural) Unused so far, and unimplemented in backends.
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 29d9a7a5 2025-04-23T18:55:52 [font] Fix get_glyph_extents() logic
Behdad Esfahbod 38db1fac 2025-04-23T18:02:06 [paint] Change back return type of paint_glyph() to void Add new "_or_fail" variants of draw_glyph and paint_glyph New API: +hb_font_draw_glyph_or_fail_func_t +hb_font_paint_glyph_or_fail_func_t +hb_font_funcs_set_draw_glyph_or_fail_func() +hb_font_funcs_set_paint_glyph_or_fail_func() +hb_font_draw_glyph_or_fail() +hb_font_paint_glyph_or_fail() Deprecated API: -hb_font_draw_glyph_func_t -hb_font_paint_glyph_func_t -hb_font_funcs_set_draw_glyph_func() -hb_font_funcs_set_paint_glyph_func()
Behdad Esfahbod eb226383 2025-04-23T01:20:48 [font] Synthesize glyph extents if needed See code for logic. Fixes https://github.com/harfbuzz/harfbuzz/issues/5273
Behdad Esfahbod e78310bf 2025-04-23T00:58:08 [paint] Change return type to bool, and return false for outline glyphs It was impossible to get synthetic bold/slant correctly with the previous API. This is a minor API break, but one I'm willing to take.
Behdad Esfahbod 5d9cff80 2025-04-22T23:01:28 [font] Move is_synthetic() to .hh
Behdad Esfahbod a69713b5 2025-04-22T21:01:04 [color] Move slanting to font layer COLRv1 is still being double-slanted. Investigating.
Behdad Esfahbod 9dbb84e6 2025-04-22T20:25:44 [font] Don't apply synthetic bold/slant to parent Fixes https://github.com/harfbuzz/harfbuzz/issues/5274
Behdad Esfahbod 1a9e2175 2025-04-22T19:52:21 [font/draw] Move slanting to font layer I moved it to the draw layer in 11.0.0; That was a bad design: font-funcs should NOT be responsible for synthetic bold & slant. This design reverts that and makes the font layer apply it, using a recording. This is a minor API change from 11.0.0 since hb_draw_state_t::slant_xy which was introduced in 11.0.0, is removed now. I believe no client had started using it. It was only relevant to other font-funcs draw implementations.
Behdad Esfahbod 9ef82f89 2025-04-22T19:35:34 [font] Embolden font_v_extents
Behdad Esfahbod 5ebd740e 2025-04-22T19:28:16 [font] Move font_h_extents emboldening to font layer
Behdad Esfahbod 78822b63 2025-04-20T04:23:35 Revert "[COLRv1] Move paint boundedness check to font layer" This reverts commit c9a26fbf47f01fdd55df1a0ccc81111cb07bf108.
Behdad Esfahbod c9a26fbf 2025-04-20T04:22:32 [COLRv1] Move paint boundedness check to font layer This way it will apply to fontations and future implementations as well. But this slows down things apparently, specially if the font does use clipboxes. So I'm going to revert.

Behdad Esfahbod d53cbeee 2025-03-31T14:24:47 [font] Fix warnings
Behdad Esfahbod 4cf4099f 2025-03-30T17:04:08 [ot/ft] Round glyph extents instead of floor/ceil 1. The floor/ceil was being applied in the wrong order for y direction. 2. If the scale is negative, the floor/ceil should be reversed. Just round them instead. That's what coretext / directwrite / fontations font-funcs do.
Behdad Esfahbod 22f81f70 2025-03-28T12:29:06 [font] Fix var initialization
Behdad Esfahbod aad5780f 2025-03-28T00:26:51 [font] Move outline emboldening to font layer Such that it works on all font-funcs.
Behdad Esfahbod 83481d65 2025-03-28T00:21:20 [font] Move emboldening advances to the font layer Instead of each font-funcs impl. TODO: Do the same for draw_glyphs.

Behdad Esfahbod 9b6da299 2025-03-02T17:00:14 [font/var] Try to regain performance of all-normalized-coords=0
Ozkan Sezer c2f8f35a 2024-03-15T18:45:24 Use inttypes.h PRI?32 macros in format strings for [u]int32_t args. This is a modified and cleaned-up version of PR #4619 by @jpcomito: hb-common.h now expects 'inttypes.h' presence with MSVC exceptions, defines __STDC_FORMAT_MACROS in there (if not already defined) and undoes c930ae2 (PR #1974) and 902ab86.

Behdad Esfahbod 595def8f 2024-03-14T12:34:39 Revert "Fixing compiler warnings" This reverts commit 61a1ba2ff0fc1b1ed9db0b7c1dd0f59a4312e6e6.

Matthias Clasen 9be01b6b 2022-12-21T14:04:32 [paint] Pass hb_paint_context_t along Replace the font argument with a hb_paint_context_t that carries the font, the palette index and the foreground color. The hb_font_paint_glyph() api now takes the palette index and the foreground color as extra arguments. Update all callers and regenerate test results.
Matthias Clasen 14b026ff 2022-12-19T13:53:49 [draw] Add hb_font_draw_glyph hb_font_draw_glyph(), hb_font_draw_glyph_func_t and hb_font_funcs_set_draw_glyph_func() are just alternative names for hb_font_get_glyph_shape and friends, to better align with hb_font_paint_glyph.
Matthias Clasen 0f287e75 2022-12-19T13:45:45 [paint] Rename hb_font_get_glyph_paint_func_t The 'get' was just there due to implementation choices. Work around that and call the vfunc what it should be: hb_font_paint_glyph_func_t.
Matthias Clasen 71efa0dc 2022-12-14T06:22:00 wip: hb_font_paint_glyph

Behdad Esfahbod 8b4f4290 2022-02-03T01:14:47 [draw] Virtualize hb_font_draw_glyph() into hb_font_get_glyph_shape() To be implemented in hb-ft.

Behdad Esfahbod da500568 2021-10-26T08:02:29 [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph Instead of using gid=0 when a character is not found in the font, client can now set a custom value. This is useful for shaper-driven font fallback and to differentiate that from .notdef glyph. Fixes https://github.com/harfbuzz/harfbuzz/issues/1360

Behdad Esfahbod f18ea1dd 2019-07-05T13:56:45 [font] Remove division when scaling Yoohoo. This seems to be precise enough! Let's see if it sticks. I'm asking Dominik to run this in Chrome test suite and report. Fixes https://github.com/harfbuzz/harfbuzz/issues/1801

Behdad Esfahbod 5570c87f 2018-11-03T14:51:38 Port objects to use header.writable instead of immutable Saves 4 or 8 bytes per object on 64bit archs.
Behdad Esfahbod 35d410f2 2018-10-29T14:45:44 Remove ASSERT_POD Newer compilers / language allows structs with constructor in union. So, this was not actually testing anything. Indeed, the recent change in DISALLOW_COPY *is* making some of our types non-POD. That broke some bots. Just remove this since it wasn't doing much, and I'd rather have DISALLOW_COPY.
