Originally it was just assuming that any Vector3ub or Color3ub is a
normalized format. That was kinda enough for many cases, but it started
to get annoying with sRGB image comparisons, as those had to be
manually reinterpret with a sRGB-less format in order to pass.
Now the pixel format detection looks at the expected image format as
well, and if the underlying type and component count matches, it
inherits the sRGB and normalized property from it as well. If not, it
falls back to an integer format for vectors, and normalized format for
colors. For vectors this is different from previous behavior but
shouldn't cause any problem in practice -- the only result will be that
the image comparison fails with a different message for pixel format
mismatch than before.
This now also properly and fully tests the pixelFormatFor() helper, and
adds a missing Color3 specialization of it.
Integer / packed formats are the majority of uses for this utility, and
for them the additional complexity with NaN and infinity handling isn't
needed at all.
Running ShadersMeshVisualizerGLTest with this change in a Debug build
led to its runtime being reduced by about 35%, the total test time
excluding benchmarks went from 14.5 seconds to 11. Not bad.
Basically mirroring the changes done for Corrade::Compare::*File*,
including storing the filenames as string views to avoid unnecessary
copies (and then paying extra attention to not pass temporaries to them
in its own tests).
Otherwise unrelated error messages such as file read failures would get
included, making the tests fail. The Debug output on the other hand
isn't used for any internal reporting.
This was working originally, but got broken when all plugin interfaces
got switched to look for plugins next to the library and not in a
hardcoded install path.
The 32-bit float depth be needed for the upcoming OpenEXR plugin, added
also the remaining ones that will be eventually supported by KTX and DDS
plugins.
Deprecated for 2018.04, it's been almost a year since. Whoever is using
Magnum regularly updated already, and who not can always upgrade
gradually (2018.02, 2018.04, 2018.10, 2019.01 etc.).
Due to that, all the tests got skipped on the CI and moreover when ABI
was broken, tests were failing hard due to ABI mismatches with system
installed plugins. No good.
Some variants still need to access the system plugin dir (such as checks
for compressed data), but those are minimal. Sanitized them nevertheless
so a broken system-installed plugin doesn't break the test.
At the moment just the GL library itself w/o the tests, and without
backwards compatibility aliases. The following types were left in the
root namespace, despite being in the GL/ directory, as they will get
moved back soon:
* Image, CompressedImage and their dimensional typedefs
* ImageView, CompressedImageView and their dimensional typedefs
* PixelStorage
Not PixelFormat etc., that one will stay in the GL namespace and a
completely new PixelFormat enum will be provided in the root namespace.
