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.
This test exercises a clone_similar extents bug noticed by
Benjamin Otte. As expected, the xlib backend fails due to
that bug, (and interestingly, the ps backend is showing a
failure as well).
This new test case demonstrates a bug in the PDF backend, (source
surface patterns are repeated even with a pattern extend of NONE).
Thanks to Romuald <mydevel@free.fr> and Claudio Saavedra
<csaavedra@alumnos.utalca.cl> for pointing out the bug.
Adds a test for missing and out-of-range glyph indexes. The expected
ATSUI renderings are added as references, please replace these with
FT renderings when they become available.
The test passes an empty string to cairo_show_text, cairo_text_path, and
cairo_text_extents, and NULL and an invalid pointer, with zero num_glyphs to
cairo_show_glyphs, cairo_glyph_path, and cairo_glyph_extents.
I must not have the right font available, (test result is coming out
looking like the result of ft-text-vertical-layout-type3, Vera?).
We should switch this test to load a bundled font, (should do that for
all font-using tests, too).
This fixes the last problem with vertical fonts in PS/PDF. As such, remove
ft-text-vertical-layout-type1 test from XFAIL and add PS-specific ref image
to pass.
The PS output for ft-text-vertical-layout-type3 looks correct, except for some
antialiasing mismatch. Ading ref image to fix this, and so, remove the test
from XFAIL.
The purpose of this test case is to help make
sure that changes to the trapezoid generation or
intersection computation in the tessellator
don't break it.
Some systems cannot handle very long list of arguments. Carl was hitting this
for "make clean". Break it out into several rm calls triggered by the
clean-local target.
The new tessellator contains a regression where stop events
that aren't followed by start events sometimes cause the
trapezoid to the left of an edge to be too high.
There's currently a regression bug in the tessellation code from
switching to the new tessellator. The bug is caused by
confusion in the comparator used to order events when there are
degenerate edges. This test is derived from the zrusin-another
performance test case.
We'll need to rewrite this test (and the way cairo is compiled for
testing) before it can exercise the bug of interest. In the
meantime, let's just give it an "expected failure" status.
This test fills a single path (a trapezoid, even) that's larger than the
16.16 precision used in pixman and other code. It leads to memory
scribbling and a crash. Note that there is no crash if a clip is not set.
I added this test originally to make it easier to debug
some recent bugs, (the test suite did have some repeating
in the checkered backgrounds, but with an offset of 0,
and then also in trap clip with an offset larger than the
surface itself). This test exercises repeating more directly.
It also triggers a bug in the PostScript backend that I've
not yet investigated. So the test does fail currently.
What was causing it was making all tests depend on all, to make sure
../boilerplate is built first. I'm not making all tests depend on
../boilerplate/libcairoboilerplate.la and ../src/libcairo.ls and added rules
to build those (by changing dir and making them).
Adds API functions for inspecting the current dash state, as well as
the contents of pattern objects:
cairo_get_dash
cairo_get_dash_count
cairo_pattern_get_rgba
cairo_pattern_get_surface
cairo_pattern_get_color_stop_rgba
cairo_pattern_get_color_stop_count
cairo_pattern_get_linear_points
cairo_pattern_get_radial_circles
