SDL API Reference                                   SDL_GetRGB(3)



NAME
     SDL_GetRGB - Get RGB values from a pixel  in  the  specified
     pixel format.

SYNOPSIS
     #include "SDL.h"

     void SDL_GetRGB(Uint32 pixel,  SDL_PixelFormat  *fmt,  Uint8
     *r, Uint8 *g, Uint8 *b);

DESCRIPTION
     Get RGB component values from a pixel stored in  the  speci-
     fied pixel format.

     This function uses the entire 8-bit [0..255] range when con-
     verting  color  components from pixel formats with less than
     8-bits per RGB component (e.g., a completely white pixel  in
     16-bit  RGB565  format  would  return [0xff, 0xff, 0xff] not
     [0xf8, 0xfc, 0xf8]).
