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