So people new to the plugin stuff can quickly get to usage introduction
and code snippets. The plugins alone don't list anything like that and
it may be *very* confusing otherwise.
Unlike most other options, where a plugin can support 3D but not 2D or
compressed but not uncompressed data, the "levels" option is orthogonal
to the rest -- if a format supports multi-level data, it obviously also
supports a case where there is just a single level, and if it supports
multi-level images, then it likely supports them for 1D, 2D and 3D, not
just some.
I used the same reasoning for the new SceneConverterFeatures interfaces
already, just "backporting" it here as well.
The bit pattern actually followed this already, but for some reason I
still went ahead and stamped out all possible combinations. Because
of that, nothing really changes on the ABI side either and the
deprecated aliases are now exactly as they were before, so no need to
bump the plugin interface version.
When for example only CMAKE_RUNTIME_OUTPUT_DIRECTORY is set, but not the
others, the original code skipped overriding the locations altogether.
This is a valid use case, as e.g. ARCHIVE and LIBRARY_OUTPUT_DIRECTORY
tend to mess with the way Visual Studio produces and consumes *.lib
files.
Furthermore, this now also handles CMAKE_*_OUTPUT_DIRECTORY_<CONFIG> in
a similar way, which is what Conan uses for example.
Similar to the change done in Corrade, see the commit for details:
878624ac36
Wow, this is probably the most backwards-compatibility code I've ever
written. Can't wait until I can drop all that.
Consistently with changes done to Utility::Path, this enforces proper
error handling on user side. Originally I didn't want to do this and
instead wanted to have a special Array instance devoted for an error
state, but that still would allow the error state be errorneously
treated as a successful but empty array.
Somehow. Heh. This causes a non-deprecated build on MSVC to break due to
a similar reason as in 54394e2c2f. And,
similarly to 3717043ae2, *again*
discovered while building bindings.
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.
Since the plugin implementations rely on the base plugin interfaces for
file handling, this affected only the tests. Also took this as an
opportunity to use the new TestSuite::Compare::StringHasPrefix etc. in
various places.
These checks covered the case when the magnum-plugins repository wasn't
installed, but didn't cover the case when it was installed but the
plugins were built against an outdated interface, had ABI issues, or
didn't load at all for various other reasons.
And prefere to use it onver OpenEXR in most AnyImage{Converter,Importer}
tests, unless the test really needs something that only OpenEXR has
(such as the verbose output for threads or configuration that needs to
be set on both export and import to make the import succeed).
Preparing for the soon-to-be-merged KTX files. Not hooking up 1D/3D and
the compressed APIs yet, doing that only when the plugins get merged so
I have a way to test.
To avoid combinatorial explosion of functions that have to be
implemented on the plugin side, the single-image variants proxy to the
multi-level variants, if available.
THe plugin interface string had to be bumped because otherwise there was
a *really nasty* silent ABI break where instead of doSetFlags() it was
suddenly calling doConvert().
Minor but very important convenience feature, especially useful when
dealing with command-line apps. This now works:
magnum-imageconverter a.png a.jpg -c jpegQuality=0.75
The AnyImageConverter gets the jpegQuality option and then
automatically propagates it to the concrete plugin (which is either
JpegImageConverter or StbImageConverter), possibly warning in case the
target plugin doesn't recognize given option (i.e., doesn't list it in
its default configuration). Previously the user had to always specify a
concrete converter implementation using -C, which was rather annoying
and nonintuitive.
First and foremost I need to expand the interface to support 3D
image conversion. But the interface was not great to begin with, so this
takes the opportunity of an API break and does several things:
* The `export*()` names were rather strange and I don't even remember
why I chose that name (maybe because at first I wanted to have an
"exporter" API as a counterpart to importers?)
* In addition, there was no way to convert a compressed image to a
compressed image (or to an uncompressed image) and adding the two
missing variants would be a lot of combinations. So instead the new
convert() returns an ImageData, which can be both, and thus also
allows the converters to produce compressed or uncompressed output
based on some runtime setting, without having to implement two
(four?) separate functions for that and requiring users to know
beforehand what type of an image will be created.
* The ImageConverterFeature enum was named in a really strange way as
well, with ConvertCompressedImage meaning "convert to a compressed
image" while "ConvertCompressedData" instead meant "convert a
compressed image to a data". Utter chaos. It also all implied 2D and
on the other hand had a redundant `Image` in the name, so I went and
remade the whole thing. As mentioned above, two of the enums now mean
the same thing, and are both replaced with Convert2D.
* Finally, similarly as changes elsewhere, I took this opportunity to
get rid of std::string in the convertToFile() APIs.
