Ewald Hew 43c015823f Objects for new interpreter (part 2).
Make the new objects copy over values.  They are essentially wrapper
types for the different decoders/builders.

* include/freetype/internal/psaux.h: Update declarations.
(PS_Builder): Add `is_t1' flag.
(PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to...
(CFF_Decoder_{Get,Free}_Glyph_Callback: ... this.
(PS_Decoder): Updated.
Add `t1_parse_callback' member.
(PSAux_ServiceRec): Add `ps_decoder_init' member.

* src/psaux/psdecode.h, src/psaux/psobjs.h: Update declarations.

* src/psaux/psdecode.c, src/psaux/psobjs.c: Implement copy with two
modes.

* src/psaux/psauxmod.c: Add builder and decoder functions to `PSAux'
service.

Werner Lemberg 6d403d089d Fix handling of ValueRecords.
For GPOS pair positioning format 1 the description of ValueRecords
in the OpenType specification (1.8.2, from today) is wrong – the

`PairSet' table.

John Tytgat b00be9f609 [cff] Fix family name logic of pure CFF fontdata (#52056).
1. If `FamilyName' is present in the CFF font, use this for
   FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
   together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".

Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).

* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

LastResort.dfont has a marginal resource ID 0xFFFF for sfnt

suzuki toshiya 71f661804e ChangeLog for last commit. 2017-09-09 01:05:44 +09:00
Werner Lemberg a3dd6d99a4 Fix multiple calls of `FT_Bitmap_Convert'.
The documentation of `FT_Bitmap_Convert' says that multiple calls do
proper reallocation of the target FT_Bitmap object.  However, this
failed for the sequence

  non-empty bitmap
  empty bitmap
  non-empty bitmap

Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
buffer if it became too small; it didn't make the buffer smaller.
For an empty bitmap following a non-empty one, only the buffer
dimension got set to zero, without deallocation.  If the next call
was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
triggered.

* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
buffer to the correct size.

* docs/CHANGES: Document it.
