* [type1/MM] Round design coordinates.Alexei Podtelezhnikov2023-02-101-5/+6
| | | | | | | | | | The design coordinates for MM fonts were not rounded.

| | | | | The ascender and descender are optional in the AFM specifications. They could be omitted or even set to zero, e.g., in the current release of URW++ base 35 fonts.

* * src/type1/t1afm.c (T1_Read_PFM): Set charmaps directly.Alexei Podtelezhnikov2022-10-031-8/+2
| | | | | | As with the previous commit, we can avoid the validation checks of `FT_Set_Charmap` and set it directly when choosing from the available list.
* [base, type1] Better handling of out-of-memory situations.Chris Liddell2022-08-211-1/+3
| | | | | | | | | | | This follows similar code in `cff_slot_done`. * src/base/ftobjs.c (ft_glyphslot_done), src/type1/t1objs.c (T1_GlyphSlot_Done): Check `internal` pointer. The Type1 problems was reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=50057.
* [type1] Directly search for eexec in private dictBen Wagner2022-06-161-46/+9
| | | | | | | | | | | | | | | | | | | | | This code originally just searched for `eexec`. This was later modified to check that the `eexec` found is valid (not in a string or comment). This was done by searching for `eexec` as before and then, for each `eexec` found, searching from the beginning using the correct parsing to see if the `eexec` was still found. If the private dictionary is large and contains many copies of `eexec` which are not valid, the initial part of the private dictionary is scanned once for each, potentially leading to n^2 parsing time. Instead of finding an initial `eexec` and then re-parsing to discover if it is valid, drop the initial search for `eexec` and just parse to find a valid `eexec`. This is strictly faster since the validation must happen anyway and avoids restarting from the beginning each time an `eexec` is found in the data. * src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1328883

* [mm] Tolerate missing Blend dictionary entriesBen Wagner2021-10-251-3/+3
| | | | | | | | | | | | | | | In a Multiple Master font, the Blend dictionary must contain valid Private, FontInfo, and FontBBox. The current code will error if any of these are present and invalid, but will not error and will provide uninitialized data if the Blend dictionary exists but does not contain one of these entries. This change reverts to the older behavior of treating any missing entries as containing all zero data and not returning an error. In the future it may be best to keep track of when these are actually initialized and error if they are not. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize.
* [mm] Delay setting blend weight and design position.Ben Wagner2021-10-211-32/+50
| | | | | | | | | | | | | | | | | | | | Previously the `blend->weight_vector`, `blend->default_weight_vector`, and `blend->design_pos` were set early to allocated but uninitialized memory under the assumption that the memory would eventually be initialized. However, it is possible that some of the required keywords may not actually be present, leaving the memory uninitialized. This is different from a present but invalid table, which would produce an error. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions.
* [type1] Revert to signed size for binary data.Alexei Podtelezhnikov2021-10-111-11/+11
| | | | | | | | Recently introduced and reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=39838 * src/type1/t1load.c (read_binary_data): Reject negative size. (parse_subrs, parse_charstrings): Use customary signed size.
* [psaux] Signedness revisions.Alexei Podtelezhnikov2021-10-101-3/+3

* Make macros for header file names optional.David Turner2020-06-0812-50/+50
| | | | | | | | | | | | | | | | | 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.
* Remove Jamfile files from the tree.David Turner2020-05-181-35/+0
| | | | | | | | 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.

* Fix handing of `FT_Bool'.Werner Lemberg2018-09-252-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
