For compressed images the expected message was completely wrong, meaning
it'd fail in any case, and they were missing a SKIP on no-assert builds.
Then, for GL::[Compressed]BufferImage the assertions in setData() were
never tested at all.
Because there's no format that'd have more than 256-byte pixels anyway,
the theoretically biggest one would be RGBA64F or some such with 32
bytes. Nevertheless, an assert is now in place to verify the bounds as
well as ensuring the pixel size is not zero.
And document that. Because the pixel size cannot be determined for it,
and one has to either pass it explicitly or use the templated overload
that figures it out implicitly via ADL. This asserted before, but only
deep inside in pixelFormatSize(), which may be confusing.
I need to do a similar treatment for compressed images with block size
properties so let's first make it behave properly for uncompressed.
This got deprecated in 069c81b9cb but
without any visible documentation bit, so it was almost impossible to
trace back to a particular version. Or know about it when using the API.
Compared to Corrade, the improvement in compile time is about a minute
cumulative across all cores, or about 8 seconds on an 8-core system (~2
minutes before, ~1:52 after). Not bad at all. And this is with a
deprecated build, the non-deprecated build is 1:48 -> 1:41.
Partially needed to avoid build breakages because Corrade itself
switched as well, partially because a cleanup is always good. Done
except for (STL-heavy) code that's deprecated or SceneGraph-related APIs
that are still quite full of STL as well.
Useful for creating pixel formats with different channel count,
adding/removing the sRGB bit and such. Counterpart to
vertexFormat(VertexFormat, UnsignedInt, bool) that got added back in
2020.06 already.
Doing so usually points to some error in user code, so directly disallow
it, instead of returning false. Such behavior is consistent with
pixelFormatChannelCount() and other helper APIs.
Because, when it fails, it'd attempt to print them as strings,
inevitably leading to a crash or garbage in the terminal. Moreover, with
the upcoming fix that makes StringView *actually* convertible from an
ArrayView, it would become ambiguous.
Apparently can't even test that the returned time is in some range. So
I'll test only that the time isn't less than expected. Which it
sometimes is, on Emscripten, so add an epsilon for that as well.
This was an annoyance with GltfImporter's customSceneFieldTypes, where
it just wasn't possible to set the options through AnySceneImporter or
magnum-sceneconverter -i argument without causing a warning to be
printed.
The behavior is now that if a plugin configuration subgroup (but not the
root group) is empty, it's assumed that new values are meant to be added
to it, and thus it doesn't warn on them.
Initially, if possible, by extracting the code into separate files and
testing those, instead of having to execute a binary and deal with
output redirection and other crazy things. The option propagation is
already extracted, so do that first.
With the intention that those will eventually contain also things like
YUp / YDown, PremultipliedAlpha and such.
This commit is mostly just busywork, wiring this into [Compressed]Image,
[Compressed]ImageView and Trade::ImageData and ensuring the flags get
correctly propagated during moves and conversions. Unfortunately in case
of Trade::ImageData it meant deprecating the current set of constructor
in order to insert an ImageFlags parameter before the importer state
pointer.
The only non-trivial piece of logic is when a 2D
[Compressed]ImageView gets converted to a 3D one, then the Array bit is
implicitly dropped, as 2D arrays of 1D images are not really a thing.
Instead, it's now possible to add new flags when doing the conversion --
for example to turn a 2D image to a (single-layer) 2D array image.
Similar to what VertexFormat already has -- getting channel count,
channel format, sRGB and color vs depth/stencil properties out of a
PixelFormat value. Very useful for various image conversion plugins.
For consistency with how VertexFormat and other enum helpers are named.
The compressedBlockSize() and compressedBlockDataSize() is also renamed
to compressedPixelFormatBlockSize() and
compressedPixelFormatBlockDataSize().
While backwards compatibility aliases are in place, a breaking change
is that Image classes now look for pixelFormatSize() instead of
pixelSize(). This is used e.g. when passing GL::PixelFormat /
GL::PixelType to the image classes, instead of the generic PixelFormat.
While useful, it's unlikely that any project was defining their own
pixel format enum and pixelSize() for a D3D or Metal renderer or
whatnot, so the breakage should have no practical impact.
While branching on a compiler is rather common, checking a particular
compiler version should be needed only rarely. Thus minimize use of such
macros to make them easier to grep for.
Again not publicly documented because I don't like the naming and I
don't have the full behavior and interactions figured out yet -- i.e.,
an array of VertexFormats would be printed with Debug::packed as a long
string of characters without any whitespace. Not good, thus this
feature probably needs to be split in two, with this being named
"compact" or something else.
It limits the support for CMake 3.12+, but it's much less verbose and I
don't expect people to use ancient CMake versions with IDEs like Xcode
or VS anyway, so this should be fine.
It's dangerous, as in case of failure it will attempt to print them as
strings. Plus now with latest de-std-string-ification of TestSuite it
causes the compilation to fail due to an ambigupus overload.
This should eventually be catched and disallowed directly by the Tester
class.
The type is now extended to 32 bits. In the GL and Vk libraries it means
one can now do things like
MeshIndexType type = meshIndexTypeWrap(GL_UNSIGNED_BYTE);
and passing that to GL::Mesh or Vk::Mesh will cause it to use the value
directly, instead of doing a mapping from a generic type. The *real* use
case for this is however to allow custom index buffer representations in
Trade::MeshData. Support for that will be hooked up in the following
commit.
