SDL_MapRGB(3)		       SDL API Reference		 SDL_MapRGB(3)

       SDL_MapRGB - Map a RGB color value to a pixel format.

       #include "SDL.h"

       Uint32 SDL_MapRGB(SDL_PixelFormat *fmt, Uint8 r, Uint8 g, Uint8 b);

       Maps  the RGB color value to the specified pixel format and returns the
       pixel value as a 32-bit int.

       If the format has a palette (8-bit) the index of the  closest  matching
       color in the palette will be returned.

       If  the	specified  pixel  format  has  an  alpha  component it will be
       returned as all 1 bits (fully opaque).

       A pixel value best approximating the given RGB color value for a	 given
       pixel format. If the pixel format bpp (color depth) is less than 32-bpp
       then the unused upper bits of the return value can  safely  be  ignored
       (e.g.,  with  a	16-bpp	format	the  return value can be assigned to a
       Uint16, and similarly a Uint8 for an 8-bpp format).
