Vladimír Vondruš	7060a83ca9	GL,Vk: inverse mapping of {Texture,Pixel}Format to generic PixelFormat. An ad-hoc solution was already done in DebugTools::screenshot(), now I need it in another place. While not as fast as the O(1) mapping from the generic format to the API-specific ones due to the potentially linear lookup, it definitely could be useful in general.	3 years ago
Vladimír Vondruš	1191eb4176	GL: whoops, mapping of these to a TextureFormat was wrong. Only noticed this now when adding inverse mapping. Sigh. OTOH, with the inverse mapping in place this will no longer be possible to happen, as it would cause a compile error due to a duplicate switch case.	3 years ago

Vladimír Vondruš	042f28a90e	GL: hook up EXT_texture_sRGB_RG8 for desktop GL as well. Was browsing the extension registry looking for something else and found this instead. It used to be ES catching up with desktop, now it's the other way around.	4 years ago
Vladimír Vondruš	aea8722729	Add generic depth/stencil PixelFormat values. 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.	5 years ago
Vladimír Vondruš	93fa1b9f94	GL: EXT_texture_norm16 is not on WebGL 1 anymore. It got changed shortly after the original implementation in `083ecf72b8` to be WebGL 2 only.	5 years ago

Vladimír Vondruš	083ecf72b8	GL: implement EXT_texture_norm16 ES and WebGL extension.	6 years ago

Vladimír Vondruš	946c3cdac9	GL: rename PixelType::HalfFloat and Attribute::DataType::HalfFloat to Half. For consistency with the Half type we use elsewhere. The old enums are still available, but deprecated and scheduled for removal.	6 years ago
Vladimír Vondruš	eef1981b43	GL: added hasTextureFormat() and textureFormat() helpers.	7 years ago
Vladimír Vondruš	40b8815b9d	Added sRGB formats to PixelFormats + R and RG sRGB GL texture formats. The extension support is a mess, as usual. This time the ES flavor supports something that desktop doesn't and WebGL lack those altogether. Yay.	7 years ago
Vladimír Vondruš	537177ca26	DebugTools: added screenshot().	7 years ago

Vladimír Vondruš	6d41597d1d	Split the OpenGL layer out, pt 9: generic pixel formats. This is quite big, so: * There are new Magnum::PixelFormat and Magnum::CompressedPixelFormat enums, which contain generic API-independent formats. In particular, PixelFormat replaces GL::PixelFormat and GL::PixelType with a single value. * There's GL::pixelFormat(), GL::pixelType(), GL::compressedPixelFormat() to convert the generic enums to GL-specific. The mapping is only in one direction, done with a lookup table (generic enums are indices to that table). * GL classes taking the formats directly (such as GL::BufferImage) have overloads that take both the GL-specific and generic format. * The generic Image, CompressedImage, ImageView, CompressedImageView, and Trade::ImageData classes now accept the generic formats first-class. However, it's also possible to store an implementation-specific value to cover cases where a generic format enum doesn't have support for a particular format. This is done by wrapping the value using pixelFormatWrap() or compressedPixelFormatWrap(). Particular GPU APIs then assume it's their implementation-specific value and extract the value back using pixelFormatUnwrap() or compressedPixelFormatUnwrap(). There's also an isPixelFormatImplementationSpecific() and isCompressedPixelFormatImplementationSpecific() that distinguishes these values. * Many operations need pixel size and in order to have it even for implementation-specific formats, a corresponding pixelSize() overload is found via ADL on construction and the calculated size stored along the format. Previously the pixel size was only calculated on demand, but that's not possible now. In case such overload is not available, it's possible to pass pixel size manually as well. * In order to support the GL format+type pair, Image, ImageView and Trade::ImageData, there's now an additional untyped formatExtra() field that holds the second value. * The CompressedPixelStorage class is now unconditionally available on all targets, including OpenGL ES and WebGL. However, on OpenGL ES the GL APIs expect that it's all at default values. I attempted to preserve backwards compatibility as much as possible: * The PixelFormat and CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or GL::PixelFormat (togehter with GL::PixelType) and GL::CompressedPixelFormat instead. There's a lot of ugliness caused by this, but seems to work well. * Image::type() functions are deprecated as they were too GL-specific. Use formatExtra() and cast it to GL::PixelType instead. Image constructors take templated format or format+extra arguments, so passing GL-specific values to them should still work.	8 years ago
