SDL_MapRGB(3)				SDL API Reference			    SDL_MapRGB(3)

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

SYNOPSIS
       #include "SDL.h"

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

DESCRIPTION
       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).

RETURN VALUE
       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).
