Werner Lemberg	2bfdc161fb	[build] Allow overriding of `ANSIFLAGS` for GNU make build. * builds/*: Implement it.	4 years ago
Alexei Podtelezhnikov	28eee3636c	[type42] Fix auto-hinting. The autohinter could not access the base (unscaled) outline in the child TrueType glyph slot. We now share the internal parts between the parent and child glyph slots. Fixes #1057. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of `T42_GlyphSlot' and replace it with the child TrueType structure.

Nikolaus Waxweiler	ebf9e5ac71	[CMake] Update dependency finders. 1. Fixes CMake using any found HarfBuzz version lower than the minimum required. This is based on HALX99's merge request at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests/31 2. Update FindHarfBuzz.cmake from https://github.com/WebKit/WebKit/blob/1ce32454/Source/cmake/FindHarfBuzz.cmake and guard post-CMake-3.1 features to keep the minimum version unchanged 3. Update FindBrotliDec.cmake to stop the warnings, based on what https://github.com/google/woff2/blob/a0d0ed7d/cmake/FindBrotliDec.cmake is doing * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Implement 1 and 2. * builds/cmake/FindBrotliDec.cmake: Implement 3.	4 years ago
Ben Wagner	06e21ffedf	[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_`) instead of `voidpf` (`void`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.	4 years ago
Alexei Podtelezhnikov	81852fbccc	Prioritize the anti-aliasing renderer module. * modules.cfg: Reorder the renderers. * include/freetype/config/ftmodule.h: Ditto.	4 years ago
Alexei Podtelezhnikov	1bc801b0d6	[sfnt] Additional guards on the POST table. Fixes timeout (#1055) analyzed by Ben Wagner, reported as https://crbug.com/1194092 * src/sfnt/ttload.c (tt_face_load_post): Check POST format. * src/sfnt/sfobjs.c (sfnt_load_face): Synthesize the missing unicode charmap only if the glyph names exist. * src/psnames/psmodule.c (ps_unicode_value): Short cut ".notdef" and ".null".	4 years ago
Daniel McArdle	de15165774	[psaux] Use doubling allocation strategy for CF2_ArrStack. Fixes timeout reported as https://crbug.com/1206181 * src/psaux/psarrst.c (cf2_arrstack_{push,init}): Implement it. * src/psaux/psarrst.h (CF2_ArrStackiRec): Drop `chunk'.	4 years ago
Alexei Podtelezhnikov	2d3f5dd294	* src/smooth/ftgrays.c (FT_MAX_GRAY_SPANS): Increase from 10 to 16. Ten was barely enough for two slanted stems. Sixteen can actually fit a bit more complicated scanlines.	4 years ago
Alexei Podtelezhnikov	c653b8d2f1	* src/smooth/ftgrays.c (FT_GRAY_SET): Adjust for better code.	4 years ago
Alexei Podtelezhnikov	8f43d324d1	[smooth] Faster bitmap sweeping. Selecting the fill rule or checking the direct mode each time we call `gray_hline' is sub-optimal. This effectively splits the direct mode into a separate code path while inlining `gray_hline' and saving 5-7% of rendering time. * src/smooth/ftgrays.c (gray_hline): Eliminated in favor of... (FT_FILL_RULE, FT_GRAY_SET): ... these new macros... (gray_sweep): ... inlined here. (gray_sweep_direct): New function that handles the direct span buffer. (gray_TWorker): Remove the span buffer. (gray_raster_render, gray_convert_glyph): Updated.	4 years ago
Alexei Podtelezhnikov	b070264521	* src/smooth/ftgrays.c (gray_hline): Simplify even-odd computations. It is too bad the even-odd rule is not used much.	4 years ago
Alexei Podtelezhnikov	967a34eee3	[type1] Avoid MM memory zeroing. * src/type1/t1load.c (t1_allocate_blend, parse_blend_design_map): Tweak allocation macros. * src/type1/t1objs.c (T1_Face_Done): Minor.	4 years ago

Ben Wagner	82fd32d674	* src/cid/cidload.c (cid_hex_to_binary): Improve return value. Add argument to return the actual number of bytes that were decoded. The actual number of bytes decoded can be quite variable depending on the number of ignored 'whitespace' bytes or early termination with `>`. (cid_face_open): Updated to use this calculated value. This avoids trusting `parser->binary_length` is always be correct and reading uninitialized bits if fewer are actually decoded. First reported as https://crbug.com/1203240	4 years ago
Alexei Podtelezhnikov	66630d882c	[sfnt] Streamline POST format 2.0 handing. To reduce memory allocations, we read an entire Pascal-string buffer and convert it to a C-string buffer. We also reject tables with Postscript glyph names exceeding 63 bytes. * src/sfnt/ttpost.c (load_format20): Implement it. (load_post_names): Check the minimal POST table size. (load_format25, tt_face_free_ps_names): Updated accordingly.	4 years ago
