* [cff] internal API is changed incompatibly for 16bit & ILP64 systems.suzuki toshiya2017-09-132-7/+7
| | | | | | | | bias calculation is expected to be ILP32, LP64 or LLP64 systems (int = 32bit). Some internal variables and internal APIs are extended to use 32bit type for 16bit systems. Using long type is too large on LP64 systems, and induces the incompatible change of the internal API for 32bit systems, it should be avoided.

* [base] Remove a check for resource ID in the resource fork driver.suzuki toshiya2017-09-092-2/+21
| | | | | | | | | | | LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format.

* [sfnt, truetype] Register the tags for marginal fonts.suzuki toshiya2017-09-093-3/+13
| | | | | | | | | | | | | | | | | | | | The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

* Fix multiple calls of `FT_Bitmap_Convert'.Werner Lemberg2017-09-053-2/+29
| | | | | | | | | | | | | | | | | | | | | | 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.
* [bdf] Fix size and resolution handling.Werner Lemberg2017-09-053-6/+42
