Ebrahim Byagowi	29efd964f2	[fuzz] Add cases that marked as wontfix Let's see if they were really false alarms, if so, let's just have them.	5 years ago

Ebrahim Byagowi	cb65150fec	[draw] minor	5 years ago
Ebrahim Byagowi	44169f3396	[draw] Fix invalid rendering of some glyph on Estedad-VF Basically reverts `11f3fca` so I can do the same tested and better later Fixes #2215	5 years ago
Ebrahim Byagowi	86c40b3a1d	[fuzz/draw] Call _get_glyph_extents Other render related APIs also may be added also later such as ot-color and future rendering things.	5 years ago
Michiharu Ariza	5ab50eebd7	collect_unicodes() with clamp, calling add_range() Use add_range instead an inner loop, clamp its input number by number of glyphs a face has. Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here used to make timeout, face's maxp has 16-bit gid limitation at least for now, using that makes sure we both fix and the timeout and don't need to change much things here also in order to support 32-bit gids also someday. Fixes #2204	5 years ago

Ebrahim Byagowi	e57ced5fc0	[gvar] Add other possibly fixed fuzzer case Speculatively should've been fixed by `61208401` https://crbug.com/oss-fuzz/20924 related	5 years ago
Ebrahim Byagowi	758fda728b	[glyf] Don't accept gids higher than maxp's glyphs number This specially becomes concerning on sub-components where a gvar table that is sanitized using maxp's glyphs number overflows when a high gid accepted here goes to it, maybe an additional check can be put there also, this however feels to be enough. Fixes https://crbug.com/oss-fuzz/20944	5 years ago
Ebrahim Byagowi	e642aab116	[subset] Add source_blob as a hb_subset_context_t field (#2203 ) So no more double sanitizing source table.	5 years ago
Ebrahim Byagowi	e90213868b	Revert "collect_unicodes() to check gid < num_glyphs with cmap 12" Didn't fix the case actually, making bots to fail. This reverts commit `15b43a4104`.	5 years ago
Ebrahim Byagowi	61208401f4	[gvar] Use hb_bytes_t.check_range instead having in house one And use TupleVarHeader calculated size for validity check. Fixes https://crbug.com/oss-fuzz/20919 and possibly other gvar related issues	5 years ago
Michiharu Ariza	15b43a4104	collect_unicodes() to check gid < num_glyphs with cmap 12 fixes #2204	5 years ago

Qunxin Liu	fcd7f33bbb	[subset] GDEF glyphClassDef subsetting support glyphClassDef uses the same ClassDef format. However, glyphClassDef table uses predefined class values so we do not remap class values.	5 years ago

Garret Rieger	38c6598c1c	Switch to C style comments.	5 years ago
Garret Rieger	52b6e0baa0	When serializing cmap14 order the offsets from smallest to largest. Current versions of OTS fail fonts with cmap 14's who's last offset does not point to the a block at the end of the table.	5 years ago

Ebrahim Byagowi	84163c83d3	[draw] Skip commands and paths not contributing anything They aren't contributing to rendering and making issue for stroking, let's skip them ourselves as Skia does also https://skia-review.googlesource.com/c/skia/+/268166 They are useful for extracting extents and so which that functionality won't be effected by this change.	5 years ago

Ebrahim Byagowi	036d868913	[draw] Add a fuzzer Specially checks correctness of the API semantics: * no move happens when a path is already opened with move-to. * no path will be left open and close-path will happen at the end of opened paths. * no path opens with a move-to and will be closed with no length. * paths start and ending points matches. * no line/quadratic/cubic command will be issued when no path is started.	5 years ago
