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 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.
The bug shows up when doing cairo_copy_path_flat for a path that has
a curve_to immediately after a close_path. When the curve is flattened
the flattener is using (0,0) as the initial point rather than the proper
close_to point.
This test also serves to ensure a similar bug doesn't crop up when
closing a path that begins with an implicit move_to, (as from cairo_arc).
In that bug the path state may have no last-move-point and the path
is closed to (0,0). This bug is not present currently, but did appear
during the development of a fix for the bug above.
that combine vertical layout with font_matrix rotation and translation.
Currently Type3 and Type1 font paths both show broken behavior.
The type1 test uses "Nimbus Sans L" as the font.
This is useful to review every once in a while to drop duplicate images that
can be dropped. For example, if there are two identical images one named
some-test-svg-rgb24-ref.png and other some-test-svg-argb32-ref.png, those two
can be replaced with some-test-svg-ref.png.
- Remove cairo_test_expect_failure. cairo-test.c now checks
env var CAIRO_XFAIL_TESTS to see if the running test is
expected to fail. The reason for expected failure is
appended to the test description.
- Test description is written out.
- Failed/crashed tests also write a line out to stderr (in red),
so one can now redirect stdout to /dev/null to only see failures.
- cairo_test() has been changed to not take the draw function
anymore, instead, draw function is now part of the test struct.
- "make check" doesn't allow limiting backends to test using env
var anymore. To limit backends to test, one should use the
TARGETS variable on the make command line.
- "make check-valgrind" now writes its log to valgrind-log instead
of valgrind.log, to not interfere with test log file processing.
This test exercises the combination of cairo_get_group_target along
with cairo_surface_get_device_offset. Something funny is currently
going on with the surfaces based on the paginated surface.
Specifically, device offsets now affect using the offset surface in
a source pattern as well as drawing to the surface. This behavior
os also verified with a new test case: test/device-offset.c
[With this change, two tests with gradients exhibit subtle differences
under device offsets. I don't think we actually care about them
though. -cworth]
Add a new cairo_ps_surface_set_size which can be used to produce a
PostScript file consisting of pages of various different sizes (or
orientations).
Also add a new test (ps-features.c) for testing this and subsequent
ps-specific function calls.
Add a new cairo_test_paint_checkered function so that tests that draw
with alpha can easily put an easy-to-see checkered background in place
first.
Add new tests caps-joins-alpha and paint-source-alpha that do simple
tests of strokes and image painting with source pattern alpha.
Also, add the checkered background to paint-with-alpha for
consistency.
