SDL_GetRGBA(3)							 SDL API Reference						    SDL_GetRGBA(3)

NAME
SDL_GetRGBA - Get RGBA values from a pixel in the specified pixel format.
SYNOPSIS
#include "SDL.h" void SDL_GetRGBA(Uint32 pixel, SDL_PixelFormat *fmt, Uint8 *r, Uint8 *g, Uint8 *b, Uint8 *a);
DESCRIPTION
Get RGBA 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]). If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque).
