When it comes to DDS textures, KImageFormats already supports a good number of RGB/YUV storage types as well as the basic Block Compressions (DXT*). It would be nice if the more recent DirectX 10+ types were supported as well, even if only for previewing BC4+ files in Dolphin/Okular. After all, with Linux getting ever more attractive for Windows gamers, Windows game modders might just follow.

Please attach to this task examples of the files you would like the plugin to open.

Thanks.

That was quick :)
FWIW, Blender *can* handle these compression types, so who knows, maybe you can borrow some code from its image library.
