| | | | | | | | | This ancient option stayed completely undocumented. Given that the 'cff' driver requires the 'psnames' module, it makes no sense today to have this macro. * src/cff/cffdrivr.c (cff_services), src/cff/cffobjs.c (cff_face_init): Remove corresponding conditional code.

(read_color_line): New parameter `read_variable`; update callers. (read_paint): Handle new enumerations.
* doc: Clarify description of `FT_Stream_IoFunc`.Stephen Holdaway2022-07-061-3/+9
| | | | | | | | | | The existing documentation comments on `FT_Stream_IoFunc` hinted at the dual seek/read behavior required for custom stream implementations to work, but it didn't explicitly explain it. Without looking at the internals of FreeType, it was easy for someone to assume their implementation should handle both seek and read operations all the time. If this is done, you get a variety of errors, but mostly just `Unknown_File_Format` (error code 0x02).

* New function `FT_MulAddFix` to compute the sum of fixed-point products.Dominik Röttsches2022-06-291-0/+34
| | | | | | | | 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.

* [stream] Fix reading s32 when long is s64Ben Wagner2022-06-181-53/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return negative values when `long` is more than 32 bits. `FT_Stream_ReadULong` would read four bytes into the LSB of an `FT_ULong` and return that. Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is more than 32 bits the cast to `FT_Long` never resulted in a negative value. Fix this by modifying `FT_Stream_Read*` to return a type of the same size as the bytes it is reading and changing the `FT_READ_*` and `FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*` but with the correctly signed type (instead of casting to what is assumed to be the type of `var` which will happen automatically anyway). There exist a few cases like with the `OFF3` variants where there isn't generally a type with the correct size. `FT_PEEK_OFF3` works around this loading the bytes into the three most significant bits and then doing a signed shift down. `FT_NEXT_OFF3` also already worked correctly by casting this signed value to another signed type. `FT_Stream_GetUOffset` works correctly but one must be careful not to attempt to cast the returned value to a signed type. Fortunately there is only `FT_GET_UOFF3` and no `FT_GET_OFF3`. All of these cases are handled correctly when reading values through `FT_Stream_ReadFields` since it generically computes the signed value through an `FT_Int32`. This change is essentially doing the same for these macros. * include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*): Update macros and return types to use fixed size types for fixed size values. * src/base/ftstream.c (FT_StreamGet*, FT_StreamRead*): Dito.
