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