We need to inverse inheritance of FT_GlyphSlot_Internal so that we
have a chance to free the rendered bitmap from the parent slot.
* src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts
of the child `ttslot' and replace it with the parent structure.
(T42_GlyphSlot_Done): Updated accordingly.
The autohinter could not access the base (unscaled) outline in the
child TrueType glyph slot. We now share the internal parts between
the parent and child glyph slots. Fixes#1057.
* src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts
of `T42_GlyphSlot' and replace it with the child TrueType structure.
(T42_GlyphSlot_Done): Updated accordingly.
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.
This is a follow-up to the previous commit.
* src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c
(sfnt_load_face), src/type1/t1objs.c (T1_Face_Init),
src/type42/t42objs.c (T42_Face_Init): Implement it.
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.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font. The indices start
with value 1; value 0 indicates font access without GX variation
data.
* include/freetype/freetype.h (FT_FaceRec): Update documentation.
* include/freetype/internal/sfnt.h: Ditto.
* src/sfnt/sfobjs.c (sfnt_init_face)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and
do argument checks.
(sfnt_load_face): Updated.
* src/truetype/ttobjs.c (tt_face_init)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting
the style name.
* src/base/ftobjs.c (open_face_from_buffer,
open_face_PS_from_sfnt_stream): Updated.

pure CFF fonts if `font_index < 0'.
Updated.

Updated.

This is a severe bug: We've missed one level of indirection, as
described in the Type 42 specification. As a result, ftview
sometimes showed incorrect glyphs for given glyph names, and even
displayed `error 0x0006' (invalid argument!) in case the number of
glyph indices differed between the Type 42 font and the embedded
TTF.
Apparently, noone ever noticed it; this shows how much Type 42 fonts
are in use...
* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
to embedded TTF's glyph index.
This is a follow-up to Savannah bug #43659.
* src/type42/t42objs.c (T42_Face_Init): Exclusively use the
`truetype' font driver for loading the font contained in the `sfnts'
array.
* src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'.
* src/type42/t42parse.c (t42_parse_sfnts): Always set
`face->ttf_size' directly. This ensures a correct stream size in
the call to `FT_Open_Face', which follows after parsing, even for
buggy input data.
Fix error messages.
Suggested by Akira Tagoh, see
http://lists.gnu.org/archive/html/freetype/2013-09/msg00030.html
* src/bdf/bdfdrivr.c (BDF_Face_Init): Return Invalid_Argument error
when the font could be opened but non-zero face_index is given.
* src/pcf/pcfdrivr.c (PCF_Face_Init): Ditto.
* src/type42/t42objs.c (T42_Face_Init): Remove unrequired FT_UNUSED
macro for face_index because it is validated in later.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").
* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.
* src/cff/cffdrivr.c (cff_glyph_load): Ditto.
* src/cff/cffgload.c (cff_decoder_prepare): Improve tracing
messages.

message.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto.
* src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message.

Note that the current version heavily chokes on FreeType, delivering
even wrong results. I will report those issues to the cppcheck team
so that a newer version gives improved results hopefully.

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.
Previously, FreeType misleadingly returned
FT_Err_Unknown_File_Format if a module was missing (or a test was
missing completely).
