Removed *Image::dataSize() and added *Image::dataProperties(), which
returns all properties separately for better introspection. This function
is now just an convenience alias to PixelStorage::dataProperties(), which
takes into account proper alignment and all other storage properties.
Yeah, sorry, I know, the enums are renamed for second or third time in a
row, first they were Image::Format, then ImageFormat, then ColorFormat
and now PixelFormat. But this time it's final and last time they are
renamed and now everything is finally consistent:
* ColorFormat::DepthComponent -- depth is not a color, thus
PixelFormat::DepthComponent makes a lot more sense.
* There will be PixelStorage classes, which will be stored in images
alonside PixelFormat/PixelType enums, making everything nicely
aligned.
* The GL documentation about glTexImage2D() etc. denotes the <format>
and <type> parameters as format and type of *pixel* data, so now we
are _finally_ consistent with the official naming.
I wonder why did I not choose PixelFormat originally. Anyway, the old
<Magnum/ColorFormat.h> header, ColorFormat, ColorType and
CompressedColorFormat types are now aliases to the new ones, are marked
as deprecated and will be removed in some future release (as always, I'm
waiting at least six months before removing the deprecated
functionality).
Added (now empty) AbstractCompressedImage class that inherits (now also
empty) AbstractImage class.
Added CompressedBufferImage, CompressedImage and CompressedImageView
classes, which are just copies of BufferImage, Image and ImageView
classes with format/type pair replaced by just format, but they
additionally need data size parameter.
Because of different use cases in Trade, the Trade::ImageData class now
handles both uncompressed and compressed format, checking the API
usage with runtime assertions. The reason for this is that a material
could just reference a image file by ID and we need to be able to
extract image of that ID without prior knowledge whether it is
compressed or not. Requiring prior knowledge of image format from the
user would make both the API and the usage far more complicated than
having Trade::ImageData which handles both cases.
On the other hand, the Image*/CompressedImage* distinction is done for
easier usage and type-safe APIs in all other cases.
I wanted to preserve the parameter-less constructor of tests, but WINAPI
requires fairly ugly entagled set of functions, passing HWND around,
which required storing it in a global var and hoping it is properly
initialized when querying it for it to be passed to application
constructor.
When this was done, it was now fairly easy to support passing also
argv/argc to application constructor, which in the future will enable
selective disabling of extensions for even better test coverage.
This however needed slightly different main() function and thus we now
have MAGNUM_GL_TEST_MAIN() instead of CORRADE_TEST_MAIN(). Using the
latter will result in an assert inside std::optional.
`char*` is now the default type for byte arrays. Results in shorter
code, less annoyances and more convenient testing. As is the case with
Corrade, I'm not doing any compatibility/deprecation layer, as most of
these functions is not widely used anyway.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Move constructor and move assignment now behaves similarly to Image
(not only the buffer but also size is swapped). Added constructor taking
size + data, reordered setData() parameters to match order in Image. The
old setData() function is now alias to the new one, is marked as
deprecated and will be removed in future release.
