Werner Lemberg 1658685967 Remove redundant inclusion of `ft2build.h'.

inclusion of `ft2build.h'.

David Turner e13391333f Make macros for header file names optional.
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.

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 f34f192535 * src/*: Add checks for parameters of API functions where missing.
`API functions' are functions tagged with `FT_EXPORT_DEF'.

Besides trivial fixes, the following changes are included, too.

* src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set
error code if no service is available.

* src/base/ftinit.c (FT_Done_FreeType): Change return value for
invalid `library' parameter to `Invalid_Library_Handle'.

* src/base/ftobjs.c (FT_New_Size): Change return value for invalid
`asize' parameter to `Invalid_Argument'.

* src/base/ftoutln.c (FT_Outline_Copy): Change return value for
invalid `source' and `target' parameters to `Invalid_Outline'.
(FT_Outline_Done_Internal): Change return value for invalid
`outline' parameter to `Invalid_Outline'.

Werner Lemberg 04edbbda3c */*: s/Invalid_Argument/Invalid_Face_Handle/ where appropriate. 2014-11-25 10:21:13 +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.
2013-03-14 10:27:35 +01:00
Werner Lemberg e30de299f2 Fix various memory problems found by linuxtesting.org.
* src/base/ftgxval.c (FT_TrueTypeGX_Free, FT_ClassicKern_Free),
src/base/ftotval.c (FT_OpenType_Free), src/base/ftpfr.c
(ft_pfr_check): Check `face'.

* src/base/ftobjs.c (FT_Get_Charmap_Index): Check `charmap' and
`charmap->face'.
(FT_Render_Glyph): Check `slot->face'.
(FT_Get_SubGlyph_Info): Check `glyph->subglyphs'.

Improve API documentation.
2010-05-22 20:03:41 +02:00
Werner Lemberg 478cca14a5 * src/base/ftpfr.c (FT_Get_PFR_Metrics): Protect against NULL
arguments.
Fix return value for non-PFR fonts.  Both problems reported by Chi
Nguyen <chint@necsv.com>.

Werner Lemberg ece8b20e6c Documentation updates, whitespace. 2004-12-13 23:16:59 +00:00
Werner Lemberg 17d7581918 * src/autohint/ahhint.c (ah_hinter_load_glyph): Patch from
2003-08-18 introduced a severe bug (FT_Render_Glyph was called
twice under some circumstances, causing strange results).  This
is fixed now by clearing the FT_LOAD_RENDER bit of `load_flags'.

* src/base/ftpfr.c (FT_Get_PFR_Metrics): Initialize `error'.
* src/psaux/psobjs.c (ps_tobytes): Initialize `n'.
* src/type42/t42parse.c (t42_parse_sfnts): Initialize `string_size'.
