Werner Lemberg ba67957d5e Fix Savannah bug #35660. 
For some divisions, we use casts to 32bit entities.  Always guard
against division by zero with these casts also.

* src/base/ftcalc.c (ft_div64by32): Remove redundant cast.
(FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast.
(FT_DivFix): Add 32bit cast (this omission triggered the bug).

Werner Lemberg 847502a217 Improve documentation of `FT_Get_Track_Kerning'. 2012-03-03 07:03:41 +01:00
Werner Lemberg ceed93e328 [psaux] Fix handling of track kerning. 
* src/psaux/afmparse.c (afm_parse_track_kern): Don't inverse sign
for `min_kern'.  It is indeed quite common that track kerning
*increases* spacing for very small sizes.

Werner Lemberg 0fc8debeb6 [truetype] Fix Savannah bug #35689.

point.

* src/bdf/bdflib.c (_bdf_parse_glyphs) <_BDF_BITMAP>: Check validity
of nibble characters instead of accessing `a2i' array.

properly.

Werner Lemberg 292144b44a [psaux] Fix Savannah bug #35657. 
If in function `skip_spaces' the routine `skip_comment' comes to the
end of buffer, `cur' is still increased by one, so we need to check
for `p >= limit' and not `p == limit'.

* src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.
 2012-03-01 14:54:47 +01:00
Werner Lemberg a33c013fe2 [truetype] Fix Savannah bug #35646.

code is now in sync with the other operators (e.g. MSIRP) which
modify twilight points.
 2012-03-01 14:04:30 +01:00
Werner Lemberg cee5d59358 [bdf] Fix Savannah bug #35643. 
* src/bdf/bdflib.c (_bdf_list_ensure): Bring code in sync with
comment before `_bdf_list_split', this is, really allocate at least
five `field' elements.
 2012-03-01 09:26:03 +01:00
Werner Lemberg 4086fb7caf [bdf] Fix Savannah bug #35641. 
* src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
_BDF_ENCODING isn't set.  We need this because access to the `glyph'
variable might be undefined otherwise.
 2012-03-01 08:55:40 +01:00
Werner Lemberg 5dddcc45a0 [truetype] Fix Savannah bug #35640.
