+# We do not test algorithm correctness but algorithm stability: an old
+# XCF should look the same when loaded with a newer GIMP.
+#
+# Current hashes were made based on renders in GIMP 2.10. To check how
+# they were made, look at the script tools/compute-layer-mode-digests.py
+# in `gimp-2-10` branch.
+#
+# In other words: DO NOT just change a hash to make the test pass. If
+# one of the test starts failing, this is very bad as it will break
+# renders of existing XCF files.
+# If bugs need to be fixed in one of the blend modes, they need to be
+# fixed for further versions while still loading XCF done with older
+# versions of GIMP the same way as they used to.
+#
+# When adding a new mode, here is how to add a new hash:
+#
+# 1. First add it without any hash and run the test.
+# 2. The unit testing will fail telling you which keys are needed (it
+#    can be keys like "auto:auto:auto" for non-mutable modes, or
+#    "linear:union:perceptual", etc. for every possible case). Add this
+#    key with an empty hash.
+# 3. Run the test again.
+# 4. The test again will fail again, this time telling you the found
+#    hash. If you consider your implementation to be correct, this hash
+#    is what you want to store in this dictionnary.
+#
+# If somehow, you want the hash to come from an older implementation,
+# you can do this:
+#
+# 1. In the second test run, the test will generate a XCF on failure
+#    (and will display its path in the test log).
+# 2. Load this XCF with your reference implementations. E.g. initially
+#    I loaded them with latest GIMP 2.10.
+# 3. Export as data in "Contiguous" configuration.
+# 4. Call sha256sum on the data file.
+# 5. The returned checksum is your reference.

Author	SHA1	Message	Date
Jehan	d084f2adc0	app: more accurate test and reference file names.	2024-10-11 10:41:50 +02:00
Jehan	c8dd12034e	More digests from CI.	2024-10-11 10:41:50 +02:00
Jehan	6cdb459c25	Hmmm…	2024-10-11 10:41:50 +02:00
Jehan	b94610f70c	Again from CI. Just a few pixels different, all perceptually identical!	2024-10-11 10:41:50 +02:00
Jehan	3af2db53c3	Plop.	2024-10-11 10:41:50 +02:00
Jehan	ebce835d79	gitlab, libgimp: also exporting as .data file and storing as artifact. This will help debugging.	2024-10-11 10:41:50 +02:00
Jehan	7b8a83eaba	app: some of the CI runners computes different digest. The data is perceptually identical or off-by-one pixels, which means these are very likely consequence of float computation slight differences, which make off-by-one u8 integers when converted back.	2024-10-11 10:41:50 +02:00
Jehan	09a2098487	libgimp: allow using the download server as fallback for data comparison storage. This way, we can have the CI run data comparison for layer mode unit testing without pushing huge data file in the repository. I don't add any textual output about this feature though, because it's not like anyone else but maintainers/admins can upload any files there anyway.	2024-10-11 10:41:50 +02:00
Jehan	3055f1a191	Adding different digest with no-SSE2 codepath.	2024-10-11 10:38:31 +02:00
Jehan	9b1c0b438c	app: adding unit testing for the non-legacy layer modes too. There were just too many possible cases, so I created a script tools/compute-layer-mode-digests.py which I am going to commit in the `gimp-2-10` branch. These are the digests generated this way with GIMP 2.10 with SSE2. "Color Erase" testing is disabled currently because it is very broken (digests are different at each export!). Some modes (Anti Erase and Replace) are not introspected, therefore they cannot be tested. Pass-through is not tested right now because it requires special-casing and a little more thought. "Behind" is not in the list of layer modes in the Layers dockable, and it could not be set in GIMP 2.10 API, but it could be set in GIMP 3.0 API. So I don't have GIMP 2.10 data. Let's use GIMP 3 data as our baseline for this blending mode testing, from now on.	2024-10-11 10:38:31 +02:00
Jehan	fbc296fc25	app: all legacy layer modes are now verified. Some operations generate slightly different pixels but all differences are minimal (in worst case, barely 0.3%) and the pixels are perceptually identical, with basically off-by-one differences (e.g. in some case, I had pixels whose value when converted to u8 would be 91.4999999…, which meant that slight float computation different are enough to make it be either 91 or 92). Even more, in 2 builds of GIMP 2.10 (flatpak or custom build), I had either the same result as 2.99 in one of the build, or sometimes a third result. But any case, none of these differences warrant being qualified as a change in the render. Therefore I make the digest to compare to into a list of digests. Hopefully we won't have to edit this list too often with more slight variant renders.	2024-10-11 10:38:30 +02:00
Jehan	630aba1303	app, libgimp: improve debugging ability in the layer mode unit testing. I add a feature so that one can drop a data file of the result as expected in the build folder. Then the unit testing framework will compare it to the layer mode render and will list of the problematic pixels, additionally to some statistical data to discover if we are likely just dealing with off-by-one issues, or some more drastic render differences.	2024-10-11 10:38:30 +02:00
Jehan	bba0013f8c	app, libgimp: WIP new infrastructure for testing layer modes. One of the points we care most about is for XCF code stability over time. In particular, loading an old XCF should render visually the same. This unit-testing infrastructure allows testing that we do not deviate when editing layer mode code. It works on u8 so that float computation precision does not come into account as well. For now, I only run it on legacy layer modes. Note that 6 legacy modes have different hash from their 2.10 counterparts (difference, subtract and all 4 HSV/HSL layer modes). In a next step, I will look more closely into them to determine if we are talking of minor, not-too relevant, differences or if we broke their implementations somehow.	2024-10-11 10:38:30 +02:00
