Werner Lemberg c679115f0d Fix AC_CANONICAL_XXX issue.
* builds/unix/configure.raw: Don't call AC_CANONICAL_BUILD and

Werner Lemberg ce33a312da FT_USE_MODULE declares things as:
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.

Werner Lemberg 5914cb621a Minor doc fixes. 2008-12-16 13:12:18 +00:00
Werner Lemberg b972a2a294 Generalize the concept of `tricky' fonts by introducing
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
engine is necessary for correct rendering.

At the same time, slightly modify the behaviour of tricky fonts:
FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
FT_LOAD_NO_AUTOHINT must be used.

Finally, tricky TrueType fonts always use the bytecode interpreter
even if the patented code is used.

* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
New macros.

* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
semantics as described above.

* src/truetype/ttobjs.c (tt_check_trickyness): New function, using
code of ...
(tt_face_init): This function, now simplified and updated to new
semantics.

* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
fonts.

* docs/CHANGES: Document it.

Werner Lemberg 1474f439b5 Really fix Savannah bug #25010: An SFNT font with neither outlines
nor bitmaps can be considered as containing space `glyphs' only.

* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
a `glyf' table is missing.

* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
`glyf' table but a non-zero `loca' entry.
(tt_loader_init): Handle missing `glyf' table.

* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.

* src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
nor bitmaps is scalable.
2008-12-09 06:51:56 +00:00
Werner Lemberg e3b083c65b * src/autofit/aflatin.c (af_latin_uniranges): Add more ranges. This

Werner Lemberg 76fffcd898 * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
0x100 instead of 0x10000; the latter value is already occupied by
FT_LOAD_TARGET_LIGHT.  Bug reported by James Cloos.


Handle SFNT with neither outlines nor bitmaps.  This fixes Savannah
bug #25010.

* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
outlines nor bitmaps.

* src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there
is no table with glyphs.

message.
