SDL_GetRGB(3)							 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 specified pixel format.

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