SDL_GetRGB

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