Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg fae4ec0525 [sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
Since 2016-05-16 we detect infinite recursion directly.

`maxComponentDepth'.

and emit a tracing message.

Werner Lemberg 730b6d7468 [sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.

- It incorrectly assumed that valid tables are always at the
  beginning.  As a consequence, some valid tables after invalid
  entries (which are ignored) were never seen.

- Duplicate table entries (this is, having the same tag) were not
  rejected.

- The number of valid tables was sometimes too large, leading to
  access of invalid tables.

* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.
Reject duplicate tables and adjust number of valid tables
accordingly.

Werner Lemberg bc25de66c1 [sfnt] Fix `OS/2' table version 5 support.
We now follow the `official' announcement from Microsoft (on the
OpenType mailing list, which unfortunately hasn't a public archive).

* include/freetype/tttables.h (TT_OS2):
s/usLowerPointSize/usLowerOpticalPointSize/,
s/usUpperPointSize/usUpperOpticalPointSize/.

* src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct
default values.
2013-11-16 07:52:20 +01:00
Werner Lemberg ee5105107b [sfnt] Implement support for `OS/2' table version 5.
See

  http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism

for the announcement.

* include/freetype/tttables.h (TT_OS2): Add fields
`usLowerPointSize' and `usUpperPointSize'.  Since FreeType returns
this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.

* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

* docs/CHANGES: Updated.

Werner Lemberg 274207eb9a [sfnt] Ignore invalid magic number in `head' or `bhed'.
Other font engines seem to ignore it also.  Problem reported by
Hin-Tak Leung <htl10@users.sourceforge.net>.

* src/sfnt/ttload.c (check_table_dir): Don't abort but warn only if
we have an invalid magic number.
2013-07-18 12:38:57 +02:00
Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only.
This is a purely mechanical conversion.
2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.
