Ebrahim Byagowi 2dda6dd7 2020-04-20T14:12:45 minor, tweak spacing turn 8 spaces to tab, add space before Null/Crap
Ebrahim Byagowi 9b7fb5c2 2020-04-17T20:12:24 Move hb_font_get_var_coords_design behind HB_EXPERIMENTAL_API
Ebrahim Byagowi 352ac63e 2020-02-11T03:03:03 Fix an unlikely UAF on the deprecated _set_glyph_func API Fixes https://github.com/harfbuzz/harfbuzz/issues/2168
Ebrahim Byagowi 40166eb0 2020-02-08T13:17:06 [var] Fix the just introduced hb_font_set_var_coords_design storing bug The memcpy call was using the current coords count which is zero initially so no copy at all. Sad that no test has caught it, should see why, will however with the upcoming style API tests.
Ebrahim Byagowi 0b76e813 2019-08-20T15:15:22 Don't use _normalize_variations to avoid twice axis fetch
Ebrahim Byagowi ab2d3ec5 2019-08-14T18:42:51 [var] Implement hb_font_get_var_coords_design Hold design coords and simulate when normalized coords are set directly.

Behdad Esfahbod 5a59de2b 2019-10-28T14:02:47 Actually add +hb_font_get_nominal_glyphs() New API: +hb_font_get_nominal_glyphs()
Ebrahim Byagowi a0b4ac4d 2019-08-24T17:57:14 Turn 8 spaces to tab across the project According to the current code style of the project
Behdad Esfahbod aaa85931 2019-08-20T13:06:10 [font] Update multipliers when creating sub_font Fixes https://github.com/harfbuzz/harfbuzz/issues/1910
Behdad Esfahbod dcb4cd40 2019-08-19T11:35:37 Minor
Ebrahim Byagowi bc27f86f 2019-08-14T22:37:00 Move HB_NO_VAR to a better place in hb-font.cc Needed for other works
Ebrahim Byagowi 6a194b68 2019-08-14T18:49:57 Minor, remove trailing spaces in hb-font.{cc,h} as .editorconfig
Behdad Esfahbod 6461143b 2019-08-13T22:20:54 2.6.0
Ebrahim Byagowi 40a4b6dd 2019-07-27T13:33:46 [var] Add a new API, hb_font_set_var_named_instance
Behdad Esfahbod b8477692 2019-07-05T13:52:09 [font] Keep font-space to user-space multiplier Part of https://github.com/harfbuzz/harfbuzz/issues/1801
Behdad Esfahbod df6edcd4 2019-07-05T13:45:15 Make face immutable in hb_font_set_face()
Behdad Esfahbod a8498731 2019-06-19T19:26:22 [config] Add HB_NO_VAR to disable variations support, enabled by HB_TINY Part of https://github.com/harfbuzz/harfbuzz/issues/1652

Behdad Esfahbod 2682efb0 2019-06-17T13:38:08 Revert "Deprecate font kern API" This reverts commit d219f899f4b2fb4b39ebc1dff9fb648fc5d6d112. API change: Un-deprecate font kern API. Part of https://github.com/harfbuzz/harfbuzz/issues/1682 We should document that this API is only necessary to hook up non-OpenType kerning. hb-ot-font will continue to NOT implement them.
Behdad Esfahbod fca27860 2019-05-11T00:37:01 [config] Make HB_DISABLE_DEPRECATED actually compile Part of https://github.com/harfbuzz/harfbuzz/issues/1652
Behdad Esfahbod 227d85e1 2019-05-10T23:15:58 Minor
Behdad Esfahbod 4d31662b 2019-04-10T15:40:03 Don't install ot-font funcs on new fonts if HB_NO_OT_FONT defined Currently linker cannot GC hb-ot-font completely because we install it on fonts by default. Don't do that if HB_NO_OT_FONT defined. Part of https://github.com/harfbuzz/harfbuzz/issues/1652
Behdad Esfahbod 447323b8 2019-01-22T12:45:40 Better fix for -Wcast-align errors
Behdad Esfahbod 81ec543d 2019-01-22T12:43:12 More -Wcast-error fixes
Behdad Esfahbod 8d05bf7d 2019-01-22T12:34:05 Fix cast-align error If compiler doesn't inline StructAtOffset, this was an error since we only disable cast-align at call-site.

Behdad Esfahbod 93ef20a8 2018-11-03T15:03:06 Replace most uses of is_inert with is_immutable
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 b9db610a 2018-10-31T14:22:31 Minor
Behdad Esfahbod cf5fa57f 2018-10-27T04:50:38 [docs] Change section titles again I think I like the uniform "hb-*" more.

Behdad Esfahbod 00cf4e5e 2018-10-27T04:07:33 [docs] Fill in some sections
Behdad Esfahbod 39bd07ae 2018-10-26T21:01:11 Fix bunch of unused parameter warnings Show up with gcc -O0. There's a few more but those are functions that need to be filled in. Maybe this is a lost battle...

Behdad Esfahbod 68c86af1 2018-10-11T21:18:20 Always compile deprecated symbols We haven't been keeping this updated. So, while we don't expose the symbols in the headers if HB_DISABLE_DEPRECATED is defined, we still always build them.
Behdad Esfahbod 07899435 2018-10-09T15:39:51 Install ot-funcs on newly created funcs **Finally**! Casual users can stop caring about font-funcs completely now, like they haven't been needing to care re unicode-funcs for a few years.
Behdad Esfahbod b314c4e9 2018-10-09T09:23:51 [font] Add get_nominal_glyphs() callback (note the plural) Unused as of now. To be wired up to normalizer, which would remove overhead and allow hb-ot-font initialization to become a no-op, so we can enable it by default.

Behdad Esfahbod c77ae408 2018-08-25T22:36:36 Rename hb-*private.hh to hb-*.hh Sorry for the noise, downstream custom builders. Please adjust.
Behdad Esfahbod 1f738094 2018-08-09T00:22:37 [atomic] Add hb_atomic_ptr_t<> and port all uses Found and fixed a couple bugs. Found a couple multithreading issues. Marked them with "XXX-MT-bug".

Behdad Esfahbod b57f18da 2017-10-11T11:47:47 Add hb_font_[sg]et_ptem() to set/get point size on font New API: hb_font_set_ptem() hb_font_get_ptem() Needed for hb-coretext optical sizing: https://github.com/behdad/harfbuzz/issues/360

Philip Withnall ffde3c9f 2017-02-08T21:56:57 hb-font: Fix a potentially undefined use of memcmp() (#413) While it’s fine to call memcmp(x, 0, 0) in practice, the C99 standard explicitly says that this is not allowed: even if the length is zero, the pointer arguments must be valid. http://stackoverflow.com/a/16363034 Coverity ID: 141178 Signed-off-by: Philip Withnall <withnall@endlessm.com>
Behdad Esfahbod d3d36918 2017-02-03T15:42:03 Add dirty-state tracking to hb_face_t

Behdad Esfahbod 5ec96d30 2017-01-22T18:52:00 [var] Adjust API in prep for 'avar' implementation The 'avar' table does not allow random access to axis maps, so change API to avoid quadratic-time implementation. Removed -hb_ot_var_normalize_axis_value(), added +hb_ot_var_normalize_variations() and +hb_ot_var_normalize_coords() instead.

Behdad Esfahbod 26648ceb 2016-09-10T02:11:05 [GX] Remove (partial) support for anisotropic variations It doesn't always work, not part of FreeType, and we were not going to expose it in the API anyway. Can always be added later.
Behdad Esfahbod c22176d4 2016-09-10T01:58:27 [GX] Handle setting var coords to NULL
Behdad Esfahbod ad69e8f0 2016-09-09T22:23:34 [GX] Add new API hb_font_set_var_coords_normalized() Will probably change.

Behdad Esfahbod ca286703 2016-03-01T19:29:36 [GX] Towards anisotropic interpolation Also hookup to ValueRecord and Anchors.
Behdad Esfahbod 33317310 2016-08-08T17:24:04 Fix sign of shift operators This one: map->mask = (1 << (next_bit + bits_needed)) - (1 << next_bit); before the fix, the shift was done as an int, causing overflow if it ever got to 1 << 31. Sprinkle 'u's around. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=634805

Behdad Esfahbod c335fd79 2016-02-25T09:16:05 In trampoline implementation of get_glyph(), don't destroy user data twice!
Behdad Esfahbod 8b5bc141 2016-02-24T19:05:23 Add get_nominal_glyph() and get_variation_glyph() instead of get_glyph() New API: - hb_font_get_nominal_glyph_func_t - hb_font_get_variation_glyph_func_t - hb_font_funcs_set_nominal_glyph_func() - hb_font_funcs_set_variation_glyph_func() - hb_font_get_nominal_glyph() - hb_font_get_variation_glyph() Deprecated API: - hb_font_get_glyph_func_t - hb_font_funcs_set_glyph_func() Clients that implement their own font-funcs are encouraged to replace their get_glyph() implementation with a get_nominal_glyph() and get_variation_glyph() pair. The variation version can assume that variation_selector argument is not zero.

Other implementations (all I know of!) can simply not set glyph_h_origin() now. I did that for hb-ot and hb-ft in 44f82750807475aa5b16099ccccd917d488df703, though that broke the fallback shaper because the default was returning false...
