The 5 additional bugs that will be shipped with 1.4 are
ft-text-vertical-layout-type1
radial-gradient
surface-pattern
surface-pattern-scale-down
surface-pattern-scale-up
Most of these are non-issues, (unbundled font for
ft-text-vertical-layout-type1), or very minor issues (radial-gradient
and surface-pattern). The only things in here that look like a real
bug are the surface-pattern-scale-down and surface-pattern-scale-up
tests where the xlib backend results have some non-1.0 alpha that is
very unexpected.
Without this, any tests that were using cairo_test_init rather than
cairo_test would end up leaking a FILE* for the log file. So this
keeps valgrind much more happy with the test suite.
Embarrassingly enough, the test suite previously never called
into cairo_pattern_create_radial at all. Unsurprisingly, this
has led to bugs creeping into the radial gradient implementation.
This means, PS/PDF/SVG do not need the final cairo_show_page() anymore.
If there is any drawing in the page, a cairo_show_page() is done
automatically.
with surface patterns. One test scaled the pattern up, another scales
down. We observe that both PS and PDF are broken when scaling down.
This is the reason that PDF is failing in the fallback-resolution test
too.
Previously we were generating an image object with the desired
transform and then a pattern with only a translation. This means,
the pattern was alwasys axis-aligned. Obviously this does not
work correctly with repeated rotated patterns.
We now use an identity matrix for the image and put all the
pattern transformation (well, it's inverse) into the pattern.
This fixes the issue nicely.
The surface-pattern test is still failing even with a reference
image, because the gs rendering of the normal case and the
device-offset=25 case are different and both have seams.
The surface-pattern test was very naive, painting a surface pattern
repeated at identity size. With the new test, the surface pattern
is scaled and rotated. This reveals a serious bug in the PS backend.
We do this through a hack, that is, we make
_cairo_pattern_acquire_surface to return a surface that has four
copies of the original surface painted such that this image can
be simply repeated to get the effect of reflecting the original
surface.
This fixes the formerly XFAIL test extend-reflect.
The bug was that the bounding box of the image was computed by transforming
the vector (width,height) and then using 0,0,width,height as the bounding box.
This is obviously wrong. We use _cairo_matrix_transform_bounding_box() now.
This fixes the XFAIL test rotate-image-surface-paint.
and update reference images. This test was fixed some time ago
where I disabled type1 subsetting for vertical layouts, then
turned XFAIL again when Carl Worth didn't have the same fonts as me.
I've not updated reference images to work on FC6 and hoping that it
works for Carl too.
This is to make librsvg and poppler to use the compiled cairo instead
of whatever is on the system, such that the test suite does not depend
on a good version of cairo being installed already.
Adds some state, 'dash_starts_on', to keep track of whether a dashed path
starts with dash_on or not. This fixes the 'leaky-dash' bug (#4863) and
some other degenerate cases. The new version is, in my opinion,
considerably cleaner and more understandable than the old code.
Finally, the rewrite changes the behaviour of dashing to add degenerate
caps around corners that start at the same place as a dash begins. This
matches the behaviour seen in acroread.
This rewrite is based on an initial rewrite done by Jeff Smith.
With 50 iterations I'm seeing the following assertion failure:
cairo-hash.c:477: _cairo_hash_table_insert: Assertion `NOT_REACHED' failed.
Thanks to Jan Slupski <jslupski@juljas.net> for pointing out this bug.
