Proofread everything, make the packages the first choice (and manual
build only as a backup catch-all solution), don't force the users to
CMake but provide useful snippets to show how to use the libs from
CMake.
And removing the bundled std::optional implementation. This finally
makes this library compatible with C++17. Since this would be a huge
backwards-incompatible change that would make everyone angry, the
following had to be done in case both CORRADE_BUILD_DEPRECATED and
MAGNUM_BUILD_DEPRECATED is defined:
* Under C++11 and C++14, Containers::Optional / Containers::NullOpt is
aliased to std::optional / std::nullopt. This is no worse than the
state before, when we also provided these symbols.
* Under C++17, where standard <optional> header is available,
Containers::Optional provides implicit conversion to it. Only one-way
conversion is supported, as there was fortunately no Magnum API that
took std::optional via parameter, and there might be some corner
cases that this doesn't cover. The goal is to have all examples
compiling with the old API, at least.
* There's a new test especially for this, which checks that both the
C++11 and C++17 ways of doing things work as they should.
The typedef and conversion is marked as deprecated, so it will spit out
many warnings to push users to upgrade. I hope I can completely remove
this mess soon :/
As with Corrade, this is not exactly backwards compatible, but for
common use case without OBJECT libraries this should not be a problem.
In any case, recreate the build dir and update your copy of all
Find*.cmake modules to avoid weird things happening.
User-facing changes:
* Documentation of all Find*.cmake modules converted to
reStructuredText to follow official CMake guidelines.
* The newfangled way to use the libraries is to link to Magnum::Shaders
instead of adding ${MAGNUM_SHADERS_INCLUDE_DIRS} to include path and
linking to ${MAGNUM_SHADERS_LIBRARIES}.
* The old ${MAGNUM_*_LIBRARIES} are deprecated and now just expand to
Magnum::* target. Use the target directly. These are also enabled
only when building with MAGNUM_BUILD_DEPRECATED.
* The old ${MAGNUM_*_INCLUDE_DIRS} are removed as the Magnum::* targets
cover these too.
Internal changes:
* Global state such as include_directories() was replaced with
target-specific settings.
In the particular case of AnyImageConverter the function needs to access
manager and load/instantiate plugin using it, which is non-const
operation. More generally, it puts unnecessary restrictions on what the
plugin can and cannot do.
Makes it far easier to detect pixel storage misconfigurations and
improperly sized data arrays. Data owning classes (Image,
Trade::ImageData) accept Containers::Array<char> while wrappers
(ImageView, BufferImage) accept Containers::ArrayView<const void>.
ImageView reinterprets the passed array as const char to enable pointer
arithmetic on the data.
The old way (constructor/setData() call accepting void*) is now marked as
deprecated and will be removed in some future release. Because decay of
fixed-size arrays to void* is preferred to calling Containers::ArrayView
constructor, there are two more overloads to have proper handling of
const T(&)[n] and std::nullptr_t arguments.
Currently the TgaImporter and TgaImageConverter fail on images with row
length not aligned to 4, will fix that in followup commits.
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).
With pixel pack/unpack support it will be possible to create views onto
sub-images, renamed the class to reflect that.
The old Magnum/ImageReference.h and ImageReference types are now aliases
to ImageView.h and ImageView types, are marked as deprecated and will be
removed in future release.
Swizzle to RGB/RGBA on all platforms. Usability over (minor) performance
benefits. Otherwise we would be like the ugly mess called QImage (in
Qt4 at least).
Mainly to fix linker errors on Windows when using static plugins as
dependencies of other plugins. Don't even let me get started on how much
I hate the dllexport/dllimport hell.
`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.
New in 2.8.9, much cleaner than the previous "solution". Also cleaned up
the surroundings a bit. Fixed cases where PIC was forced independently
of the settings, for plugins the PIC is now also set only when
needed/requested.
They need to be installed into possibly system-wide location on Windows
and thus we need to avoid name clashes (or at least explicitly show that
e.g. TgaImporterTestLib.dll belongs to Magnum and is not any OMG virus).
