16586859 | 2020-06-13 21:15:45 | Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. | |
 |
e1339133 | 2020-06-08 13:31:55 | Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation. | |

|
0d945929 | 2016-09-27 08:44:31 | [truetype] Introduce dynamic limits for some bytecode opcodes. This speeds up FreeType's handling of malformed fonts. * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number of twilight points, the total number of negative jumps, and the total number of loops in LOOPCALL opcodes. The values are based on the number of points and entries in the CVT table. (Ins_JMPR): Test negative jump counter. (Ins_LOOPCALL): Test loopcall counter. * src/truetype/ttinterp.h (TT_ExecContext): Updated. * docs/CHANGES: Updated. | |

b1e7b68e | 2016-09-08 08:56:34 | * src/truetype/ttinterp.c: Include `ttgxvar.h'. This fixes the `multi' build. | |
|
a4c2a311 | 2016-08-22 19:32:34 | [truetype] Fix `MPS' instruction. According to Greg Hitchcock, MPS in DWrite really returns the point size. * src/truetype/ttobjs.h (TT_SizeRec): Add `point_size' member. * src/truetype/ttdriver.c (tt_size_request): Set `point_size'. * src/truetype/ttinterp.h (TT_ExecContextRec): Add `pointSize' member. * src/truetype/ttinterp.c (TT_Load_Context): Updated.

053943a7 | 2016-07-30 00:27:48 | [truetype] Comment. | |
|
3a528bbe | 2016-07-22 06:59:36 | [truetype] Record the end of IDEFs. To match the logic in FDEF. The value of the end is only used for bound-checking in `Ins_JMPR', so it may not have been obvious that it was not recorded. Tested (as part of Font Validator 2.0) all the fonts on Fedora and did not see any change. * src/truetype/ttinterp.c (Ins_IDEF): Updated. | |
|
a3b70d76 | 2016-07-18 06:23:36 | [truetype] Make GETDATA work only for GX fonts. * src/truetype/ttinterp.c (opcode_name): Updated. (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'. (TT_RunIns): Updated. | |
|
8c93013c | 2016-07-17 22:40:31 | [truetype] Add support for Apple's GETDATA[], opcode 0x92 bytecode instruction. It always returns 17, and we have absolutely no idea what it is good for... * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated. (Ins_GETDATA): New function. (TT_RunIns): Add it. | |
|
e0843609 | 2016-07-16 18:46:28 | [truetype] Add bytecode support for GX variation fonts. This commit implements undocumented (but confirmed) stuff from Apple's old bytecode engine. GETVARIATION[], opcode 0x91 This opcode pushes normalized variation coordinates for all axes onto the stack (in 2.14 format). Coordinate of first axis gets pushed first. GETINFO[], selector bit 3 If GX variation support is enabled, bit 10 of the result is set to 1. * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H. (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated. (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector bit 3, checking support for variation glyph hinting. (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to implement opcode 0x91. (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91. | |
|
32a32062 | 2016-07-16 16:39:26 | [truetype] Fix GETINFO bytecode instruction. * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for stretching information. | |
|
86eb43a9 | 2016-07-16 06:37:57 | * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. Problem reported by Hin-Tak Leung. | |
|

|
b4598828 | 2016-05-31 08:39:52 | [truetype] Let SHPIX move points in the twilight zone in v40. * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in the twilight zone. Otherwise, treat SHPIX the same as DELTAP. Unbreaks various fonts such as older versions of Rokkitt and DTL Argo T Light that would glitch severly after calling ALIGNRP after a blocked SHPIX. | |

ed1d8983 | 2016-05-18 06:58:44 | [truetype] New implementation of v38 bytecode interpreter [2/3]. This patch actually modifies the bytecode interpreter. See added comments in `ttinterp.h' for more information on this and the following commit in the series. * src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by... (NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY, SUBPIXEL_HINTING_MINIMAL): ...new macros. (Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backwards compatibility. Updated.
