Werner Lemberg ffee64afb8 Better tracing of loaded glyphs.
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").

Werner Lemberg e8ed2d621e Another round of cppcheck nitpicks.
The call was (from the top-level of the FreeType tree):

           -I /usr/include \
           -I /usr/local/include \

           -DFT2_BUILD_LIBRARY \
           . &> cppcheck.log

using cppcheck git commit f7e93f99.

Note that cppcheck still can't handle `#include FOO' (with `FOO' a
macro).

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.

Ken Sharp 980b76ea5e Really fix Savannah bug #28678 (part 1).
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only.  For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction.  Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).

Werner Lemberg 11cb8c36ed Use 16.16 format while parsing Type 1 charstrings.
This fixes Savannah bug #26867.

Previously, only integers have been used which can lead to serious
rounding errors.

However, fractional values are only used internally; after the
charstrings (of either Type 1 or 2) have been processed, the
resulting coordinates get rounded to integers currently -- before
applying scaling.  This should be fixed; at the same time a new load
flag should be introduced, to be used in combination with
FT_LOAD_NO_SCALE, which indicates that font units are returned in
16.16 format.  Similarly, the incremental interface should be
extended to allow fractional values for metrics.

field.

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 913a365090 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.
