A structure that contains pixel format information.
Everything in the pixel format structure is read-only.
A pixel format has either a palette or masks. If a palette is used Rmask
, Gmask
, Bmask
, and Amask
will be 0.
An SDL_PixelFormat describes the format of the pixel data stored at the pixels
field of an SDL_Surface. Every surface stores an SDL_PixelFormat in the format
field.
If you wish to do pixel level modifications on a surface, then understanding how SDL stores its color information is essential.
For information on modern pixel color spaces, see the following Wikipedia article: http://en.wikipedia.org/wiki/RGBA_color_space
