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
Garret Rieger 2cfa5505 2024-03-27T23:21:57 [instancer] Switch to doubles for delta calculations. FontTools uses double's internally so match FontTool's precision so we get the same results more often for floating point calculations.
Garret Rieger 975bd39b 2024-03-27T19:28:53 [subset] Match hb rounding to fonttools for avg char width. Update Muli and Roboto input test fonts to recalc class values. FontTools recalcs class values during instancing while harfbuzz does not (like the ft subsetter).
Garret Rieger ec46c4c2 2024-03-27T18:11:26 [subset] Update subset test suite to match some changes made to fonttools. FontTools has added pruning functionality for code pages which we don't yet have in harfbuzz. Update our test runner to disable that for now. Also match fonttools and always recalc usFirst/LastCharIndex even if no prune unicode ranges is set.
Qunxin Liu d550e16a 2023-11-06T10:31:05 [instancer] Recalc avgcharwidth after instancing
Behdad Esfahbod f31fb431 2023-11-06T11:29:30 Remove a couple unnecessary barriers
Behdad Esfahbod 7ee7e2e3 2023-11-04T15:02:28 [sanitize] Add remaining hb_barrier() annotations I'm sure I've forgot some. But this is a good start.
Qunxin Liu 6e49128a 2023-09-01T10:27:40 [instancer] always check and update default wght/width/slnt if necessary Sometimes default values in original file are incorrect, and if default value for an axis is not changed, then these values won't be updated
Behdad Esfahbod 67b16247 2023-06-07T16:15:48 [set] Simplify a few set iterations as range loop
Qunxin Liu bf298e50 2023-05-01T13:40:19 [instancer ]update OS_2/post/glyf tables to accept Triple for axes positions
Behdad Esfahbod 81b942e3 2023-01-12T18:42:22 [os2] Comment

Qunxin Liu 8a552483 2022-10-27T09:43:07 [instance] update OS2/.usWeightClass and .usWidthClass when no-prune-unicode-ranges option is enabled
Qunxin Liu f8ddb999 2022-08-30T09:08:09 [instance] Fix os/2 table width to widthclass mapping
Qunxin Liu 4882c717 2022-07-27T12:54:33 [instance] update OS/2.usWeightClass and OS/2.usWidthClass
Khaled Hosny c3f590bb 2022-06-16T11:04:13 [arabic] Support legacy PUA shaping Support legacy pre-OpenType Windows 3.1-era fonts, by remapping PUA code points in cmap table and letting our fallback shaper build the GSUB table. Uniscribe applies also mset-like substitution, but our fallback mark positioning gives better results, so this is not implemented.
Garret Rieger 46d4a5e6 2021-07-29T15:07:13 [subset] Convert subset plan to use a flags bit set.
Garret Rieger 9aa0ecef 2021-07-14T17:27:14 [subset] de-duplicate the logic that finds unicodes corresponding to requested glyphs. Move the logic into subset planning and then re-use the results in cmap and OS2 subsetting. Removes depedency on cmap from os2.
Qunxin Liu eee7b459 2021-06-24T10:17:46 [subset] add option --no-prune-unicode-ranges
Behdad Esfahbod bbbea3db 2021-02-11T12:23:33 [minor] Rewrite set operation in OS/2 subsetting This patch could be nicer: https://github.com/harfbuzz/harfbuzz/pull/2572/files Just tiny touchup now.
Qunxin Liu 8e5bc535 2020-07-15T18:54:52 [subset] call collect_mapping only when --gids option is used. collect_mapping is time consuming as it iterates all codepoints in all cmap subtables, only trigger it when necessary
Qunxin Liu b2a965df 2020-04-22T15:58:41 [subset] Add support for "--gids" option cmap subsetting now retains entries associated with any glyph ids explicitly requested
Ebrahim Byagowi 8f6d0f84 2020-04-17T11:30:27 [os2] minor, fix font_page_t enum naming As https://github.com/harfbuzz/harfbuzz/pull/986#pullrequestreview-395052800

Behdad Esfahbod 2bd953ff 2019-07-18T14:25:45 [metrics] Fix weird use of xor I believe that was a try to use one approach as fallback to other. But felt wrong. Just believe what's in OS/2 table to be correct.
Ebrahim Byagowi 87e62843 2018-11-20T23:26:46 Implement a simple API for fetching opentype metrics Fixes https://github.com/harfbuzz/harfbuzz/pull/1432

Ebrahim Byagowi 6771e79b 2018-04-17T09:36:52 Add pre-opentype font pages detection code (#986) As Khaled's finding on #981 this is the way Uniscribe detects those fonts. This is its detection part.
Ebrahim Byagowi 277e3289 2018-04-17T09:13:35 Make some of implicit header uses explicit (#989) Splitted from #950 and #986 IIRC Chromium had a policy about this encouraging it, not sure about automated way to detect and add them but for now lets have the needed ones of them.
