Convert one of the enumerated pixel formats to a bpp value and RGBA masks.
SDL_bool SDL_PixelFormatEnumToMasks(Uint32 format,int *bpp,
Uint32 * Rmask,
Uint32 * Gmask,
Uint32 * Bmask, Uint32 * Amask);
format |
one of the SDL_PixelFormatEnum values |
bpp |
a bits per pixel value; usually 15, 16, or 32 |
Rmask |
a pointer filled in with the red mask for the format |
Gmask |
a pointer filled in with the green mask for the format |
Bmask |
a pointer filled in with the blue mask for the format |
