bec4ef41 | 2022-07-01 12:04:28 | [base] Round values in `FT_MulAdd_Fix`. This avoids regressing Blink layout tests and makes `FT_MulAdd_Fix` delta retrieval implementation consistent with the previous implementation, which used `FT_fixedToInt` and included rounding. * src/base/ftcalc.c (FT_MulAdd_Fix): Implement it. Also fix remaining `temp` initialization compilation issue. Fixes #1169. | |
|
0607e0e9 | 2022-06-30 10:55:50 | Fix initialisation of temp variable in new FT_MulAddFix src/truetype/ttgxvar.c (FT_MulAddFix): Initialise `temp`. | |
|
15fef219 | 2022-06-29 11:48:10 | New function `FT_MulAddFix` to compute the sum of fixed-point products. This function, based on the code of `FT_MulFix`, uses 64-bit precision internally for intermediate computations. * include/freetype/internal/ftcalc.h, base/ftcalc.c (FT_MulAddFix): Implement it. | |

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. | |

9ac9060d | 2018-06-03 09:01:17 | [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up.

fbe2fe4c | 2017-05-29 13:29:28 | Handle some integer overflow run-time errors (#46149, #48979). This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. | |

059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |

30f1e6ca | 2013-02-01 14:50:08 | Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'. | |

e9f330ad | 2013-01-24 09:12:56 | [base] Make `FT_Hypot' really internal. * include/freetype/fttrigon.h (FT_Hypot): Move to... * include/freetype/internal/ftcalc.h: This file. * src/base/fttrigon.c (FT_Hypot): Move to... * src/base/ftcalc.c: This file. Include FT_TRIGONOMETRY_H. * src/truetype/ttgload.c: Don't include FT_TRIGONOMETRY_H. | |

869fb8c4 | 2013-01-23 19:43:28 | [base] Split out MSB function. * src/base/fttrigon.c (ft_trig_prenorm): Borrow from here. * include/freetype/internal/ftcalc.h (FT_MSB): Declare here. * src/base/ftcalc.c (FT_MSB): Define here. | |

ba67957d | 2012-03-03 12:27:18 | Fix Savannah bug #35660. For some divisions, we use casts to 32bit entities. Always guard against division by zero with these casts also. * src/base/ftcalc.c (ft_div64by32): Remove redundant cast. (FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast. (FT_DivFix): Add 32bit cast (this omission triggered the bug). | |

b211651a | 2008-09-12 16:27:48 | * autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1. Some other minor fixes. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. Formatting, documentation improvements. | |
|
f47d263f | 2008-09-02 02:21:58 | * include/freetype/ftoption.h, include/freetype/ftconfig.h, builds/unix/ftconfig.in, include/freetype/freetype.h, src/base/ftcalc.c: Make FT_MulFix an inlined function. Also provide an assembler implementation for ARM architectures. this is done to speedup FreeType a little (on x86 3% when loading+hinting, 10% when rendering, ARM savings are more important though). Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX in ftconfig.h | |

50997cd7 | 2008-07-16 21:03:40 | * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error. * src/base/ftcalc.c (FT_MulFix): Fix portability issue. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: Fix compiler warning. | |

4e7d984d | 2008-06-27 22:26:11 | * src/ftlyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to... * src/ftcalc.c: Here. This fixes Savannah bug #23729. | |
|
ad83e05b | 2008-06-15 11:06:12 | * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly from clobbering. Patch from Savannah bug report #23556. * docs/CHANGES: Document it. | |

e6e6eade | 2008-05-14 23:05:38 | Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it. | |

913a3650 | 2006-11-19 09:19:17 | Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'. | |
