8eab5110 | 2023-12-14 06:59:05 | [CFF] Extract `BlueValues` as `Fixed` rather than `Int`. This is a follow-up to commit 26a7f047, [cff] Make blend operator work with floats in private dicts. which addressed the 'party baseline' bug. However, the reporting user indicated that the default location and some other points in design space rendered OK, but other points in design space still had problems. The most obvious issue being that the x-heights of lower-case letters did not align; see https://github.com/adobe-fonts/source-serif/issues/121#issuecomment-1773794136 After some analysis we determined that this was due to an interaction between `BlueValue` rounding and the zone-based algorithm. In short, for a point to be considered in a zone it must fall within the bounds of the zone. (There is a slop factor in some cases, but only a very small one.) In the Adobe-contributed side of the code, point values are not integer-rounded, instead they're kept as (some form of) fixed. Rounding just the `BlueValues` means that points that need to be considered within a zone will fall outside of it at some points in design space. The majority of this patch changes the storage and parsing of `BlueValues` to keep them as `FT_Fixed`. No significant code changes were needed because the values are converted to `Fixed` anyway when stored in `CF_BlueRec`. No attempt was made to address problems in the older pshinter code beyond converting the values from `FT_Fixed` to `FT_Short` when copying the private dictionary. (However, as the point values are also rounded in that code, the problem is much less likely to occur, although inconsistency between rounding and truncation could cause an analogous problem.) * include/freetype/internal/cfftypes.h (CFF_PrivateRec): Use `FT_Fixed` for `blue_values`, `other_blues`, `family_blues`, and `family_other_blues`. * src/cff/cffload.c (cff_blend_doBlend): Updated. * src/cff/cffobjs.c (CFF_fixedToInt): New macro. (cff_make_private_dict): Use it. * src/cff/cffparse.h (cff_kind_delta_fixed): New enum value. * src/cff/cffparse.c (do_fixed): Updated. (CFF_FIELD_DELTA, CFF_FIELD_DELTA_FIXED, CFF_DELTA_KIND): New set of macros, replacing `CFF_FIELD_DELTA`. (cff_parser_run): Updated to handle fixed-float deltas. * src/cff/cfftoken.h: Updated to use `CFF_FIELD_DELTA_FIXED` for blue values. * src/psaux/psblues.c (cf2_blueToFixed): Removed, no longer needed. (cf2_blues_init): Updated. * src/pxaux/psft.c, src/pxaux/psft.h (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated signatures. * src/psaux/psobjs.c (t1_make_subfont): Updated. | |

 |
034e5dbf | 2022-02-22 20:37:43 | [psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259 | |
|
8e39e42e | 2022-02-02 11:35:14 | [psaux] Revise `PS_Table` handling. The old impleemntation was not using `FT_REALLOC`, buing too careful with the offset rebasing. It shoudl be safe to rely on the base movements. * src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine into... (ps_table_realloc): ... this function based on `FT_REALLOC`.

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. | |
|
4eee1340 | 2020-05-18 09:16:12 | Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete. | |

f2b64583 | 2019-07-04 14:04:52 | [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. | |

6a4718a3 | 2019-03-05 17:25:19 | Fix use of uninitialized memory. * src/psaux/psintrp.c (cf2_interpT2CharString): The call to `cf2_arrstack_setCount' may fail because the allocator ran out of memory. When this happens the stack is still written to before the error condition is checked. This means that FreeType writes outside of allocated memory. This commit moves the error check prior to the stack assignment, hence the function now properly returns with an error condition. | |

All of the Type 1 path building is done with code common to the revised CFF engine, with the exception of closepath, which was still calling ps_builder_close_contour(), thus previously cached segments were not always written to the path, and glyph corruption, or even invalid outlines were possible. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'. | |
