Libraries

These libraries can extend the core SDL functionality.

Please note that several of these have names that start with "SDL_", but none of them are part of the core SDL library. They are separate and optional extras!

SDL_image

Loads images as SDL surfaces and textures, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, SVG, TGA, TIFF, WEBP, XCF, XPM, XV (and more!)
