f6509933a4 PDF: Fix glyph positioning bug 2008-04-04 08:41:08 +10:30
Chris Wilson
bb76eb508b [cairo-truetype-subset] Check reads are within valid data. 
Check cairo_truetype_font_remap_composite_glyph() does not read beyond
the end of the buffer loaded for the glyf.

Chris Wilson
a5e2a2ad2d [cairo-truetype-subset] Prevent accesses beyond the end of the glyph array. 
Reject the font if we try to remap a composite glyph that exists outside
the known set of glyphs.

13cdfed894 [cairo-truetype-subset] Perform a quick sanity check that glyf end >= begin. 
Check for a bogus glyf position and prevent an integer overflow.

cfff3c3bd0 [cairo-array] Guard against integer overflow whilst growing the array. 
Sanity check the arguments to _cairo_array_grow_by() such that the
array size does not overflow, similar to the defensive checking of
parameters to malloc.

6101dc3e93 [cairo-pdf-surface] Do not bitswap big-endian A1 masks. 
Pixman stores the bits A1 surfaces in native byte order, PDF stores
A1 masks in MSb - so only perform swapping for little-endian machines.

Note this also removes the extraneous packing as per the PDF spec 4.8.2:
"Byte boundaries are ignored, except that each row of sample data must
begin on a byte boundary. If the number of data bits per row is not a
multiple of 8, the end of the row is padded with extra bits to fill out
the last byte."

7901eb29ef [test] Add a1-mask. 
Add a variant of the a8-mask test case that exercises the FORMAT_A1 code
paths instead.

5aa5aeb1f5 [cairo-font-face] Cleanup up the font_face on the error path. 
A missing _cairo_toy_font_face_fini() was leaking the strdup(family).

eb3eb0252b [cairo-xlib-surface] Avoid writing to the error surface. 
Insert status checks during construction of temporary glyph surfaces
to avoid potentially writing to the inert error object.
 2008-04-02 17:33:30 +01:00
Chris Wilson
c1062bf20a [cairo-xlib-surface] Preserve Visuals for non-TrueColor similar surfaces. 
Previously, given a valid XRenderFormat the Visual was discarded
when creating similar surfaces. However the original Visual is
required to support reading back from non-TrueColor surfaces.
 2008-04-02 10:50:48 +01:00

b3a70629f8 [test/text-transform] Fix pattern leak. 
Add missing cairo_pattern_destroy.
 2008-04-02 10:50:48 +01:00
Chris Wilson
37c69c0d54 [cairo-xlib] Handle malloc failures for cairo_xlib_visual_info_t. 
Tidy the error paths whilst handling visuals, in particular avoiding a
couple of potential NULL deferences, missed status checks and fresh
leaks.
 2008-04-02 10:50:48 +01:00
Chris Wilson
0cd42c25a6 [cairo-svg-surface] Check surface status before extracting the svg target. 
We need to check and report the existent status, else we may try to
modify the inert error object.
 2008-04-02 10:50:47 +01:00
Chris Wilson
013bbda637 [cairo-ps-surface] Check surface status before extracting the ps target. 
We need to check and report the existent status, else we may try to
modify the inert error object.
 2008-04-02 10:50:47 +01:00
Chris Wilson
cebb1eef43 [cairo-svg-surface] Missing status check. 
Check and, if necessary, propagate the error status - do not allow the
status to be overwritten, potentially masking the original error.
 2008-04-02 10:50:47 +01:00
Chris Wilson
94db91b65e [cairo-pdf-surface] Do not mask error during cleanup. 
Be careful to preserve the original error status whilst on the common
cleanup path for _cairo_pdf_surface_emit_meta_surface().
 2008-04-02 10:50:47 +01:00

3580b99a8f [cairo-pdf-surface] Check surface status before extracting the pdf target. 
We need to check and report the existent status, else we may try to
modify the inert error object.

34d734365b [cairo-svg-surface] Release acquired surface on error path. 
Ensure the surface returned from _cairo_pattern_acquire_surface() is
released on the error path.
 2008-04-02 10:50:47 +01:00
Chris Wilson
ba2e82d138 [cairo-ps-surface] Check error status before potential illegal dereference. 
After acquiring the source image, check for the error status to ensure
that we do not attempt to deference an invalid surface.
 2008-04-02 10:50:47 +01:00
Chris Wilson
767add1ee3 [cairo-pdf-operators] Destroy stream on error. 
We cannot guarantee that a newly created error stream is a static error
object, so we need to always destroy the stream on the error path. (One
day this may change with the global pool of error objects...)

An especial thanks to Vladimir Vukicevic and the Mozilla
Foundation for a tremendous amount of work on cairo-quartz

07130a9061 Include cairoint.h first to satisfy the test suite 
Forgetting to include cairoint.h (or not including it first) can
cause some subtle bugs due to specific feature flags not being
set, etc.

46ea00d829 More quieting of subtle potentially-uninitialized warnings 
The compiler isn't clever enough to notice that these
variables are always initialized (in either the TrueColor
or ! TrueColor conditions corresponding to the later
identical conditions in which the variables are used).
