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 speci-
fied 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 component (e.g., a completely white
pixel in 16-bit RGB565 format would return [0xff, 0xff,
0xff] not [0xf8, 0xfc, 0xf8]).
