* tests: consolidate redundant, duplicated helper code
These functions currently exist in a sourced shell library, but there is
an identical copy of them in a single test file. Get rid of this
duplicate definition.
* tests: mark some tests as skipped if bc is not installed
`exit 77` is the GNU exitcode protocol for tests that cannot be run
because their prerequisites are not available. If `bc` is not installed,
and it often isn't, the test can be short-circuited instead of failing;
meson will report them in "warning yellow".
* tests: mark some tests as skipped if support is not compiled
Not all test cases can be cleanly marked as skipped -- sometimes,
multiple things are checked, and having one be unavailable should not
mean skipping all tests.
But in a couple cases, a test file only tests one thing, and that may be
skipped. In such cases, it can be semantically indicated in the test
harness report collection, that a skip occurred.
* seems to export to cmyk+2 correctly
We'll need something fancier for import.
* more hacking
* Revert "more hacking"
This reverts commit fcdad5b491fc4d5a1750388947e42d1e98b1d9d7.
* generalise to many colour export
Should work up to 12 colour profiles (all that lcms supports).
* support import with N-colour profiles
* CI: upgrade macOS runner to version 12 (Monterey)
* CI: upgrade actions/checkout to v3
* CI: remove retry logic for apt
The Linux runners on GitHub Actions already retries up to 10 times,
see:
6c93c24107/images/linux/scripts/base/apt.sh (L11-L12)
* CI: remove redundant `DEBIAN_FRONTEND=noninteractive` env
The Linux runners on GitHub Actions already sets this env variable,
see:
6c93c24107/images/linux/scripts/installers/dpkg-config.sh (L10)
* CI: remove redundant `HOMEBREW_NO_AUTO_UPDATE=1` env
The macOS runners on GitHub Actions already sets this env variable,
see:
6c93c24107/images/macos/provision/configuration/environment/bashrc (L26)
* CI: prefer shorthand flag of apt-get `--fix-missing`
* CI: install libjxl on macOS runner
* Update test suite's README.md
* spngsave: ensure quantisation occurs last
i.e. after setting the metadata and phyiscal pixel dimensions,
since quantisation will overwrite the image.
* spngsave: avoid over-allocation of temporary buffer
For low-bitdepth write and palette-based output.
* reducev: initialize the sum with the addition
Avoids an Orc opcode.
* convi: initialize the sum with the addition
Avoids an Orc opcode.
* vector: add comments to magic numbers
* Inverted order of TIFF tag writing when saving multi-page subifd pyramids to ensure that subifd pyramid layers are correctly tagged as reduced-image subfile type and not as pages
* Use if-else clause to avoid tag overwriting
We added a check that loader ->header() and ->load() methods set the
same dhint. This commit removes that check -- it's not possible to make
header and load match in all cases since images can take so many routes,
and can change between the two events.
If we see performance issues around inappropriate cache sizing again,
try to fix just those cases.
