Sam Lantinga 2ba76dbe80 Simplified SDL_Surface
SDL_Surface has been simplified and internal details are no longer in the public structure.

The `format` member of SDL_Surface is now an enumerated pixel format value. You can get the full details of the pixel format by calling `SDL_GetPixelFormatDetails(surface->format)`. You can get the palette associated with the surface by calling SDL_GetSurfacePalette(). You can get the clip rectangle by calling SDL_GetSurfaceClipRect().

SDL_PixelFormat has been renamed SDL_PixelFormatDetails and just describes the pixel format, it does not include a palette for indexed pixel types.

SDL_PixelFormatEnum has been renamed SDL_PixelFormat and is used instead of Uint32 for API functions that refer to pixel format by enumerated value.

SDL_MapRGB(), SDL_MapRGBA(), SDL_GetRGB(), and SDL_GetRGBA() take an optional palette parameter for indexed color lookups.

Simple DirectMedia Layer

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

SDL officially supports Windows, macOS, Linux, iOS, and Android. Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python.

This library is distributed under the zlib license, which can be found in the file "LICENSE.txt".

Information on building SDL with CMake is available in README-cmake.md

The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date.

Information on reporting bugs and contributing is available in README-contributing.md

More documentation and FAQs are available online at the wiki

If you need help with the library, or just want to discuss SDL related issues, you can join the SDL Discourse, which can be used as a web forum or a mailing list, at your preference.

If you want to report bugs or contribute patches, please submit them to our bug tracker

Enjoy!
