We have switched back and forth quite a few times. This time I'm switching
because with pngalpha we get gray antialiased text and graphics while with
png16m all we get is no antialiasing. This is definitely a bug in the png16m
driver, but I won't wait until it gets fixed upstream.
Previously Carl Worth switched to pngalpha and reverted it immediately in
commit c4fc7b06b5. I've now fixed image-diff to
work with the output of pngalpha, so we can switch. It requires lots of
reference image updates, but still doesn't help with reducing the number of
PS-specific reference images we need.
Previously it was using the equation 128+diff/3, which results in
lots of gray and de-emphasized difference. Now it's using
MIN(255,diff*4) which more emphasizes the real difference.
that includes all tests depending on CAIRO_ANTIALIAS_NONE and
CAIRO_ANTIALIAS_SUBPIXEL.
This removes separate pdf_ignored_tests and svg_ignored_tests
arrays that were out of synch and otherwise the same.
Do a funny transition of CAIRO_TEST_TARGET through TARGETS such that
one can limit tested targets both through CAIRO_TEST_TARGET env var
and TARGETS make var on the command line.
- 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.
- Add new target recheck, that checks only failed tests
- Add targets test and retest, and make html after (re)checking
- Make targets html and index.html lazy, only update if any tests changed
- Improve build system such that checking one test (using TESTS=...) doesn't
build all tests
- Remove pixman-rotate from XFAIL
