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 com-
       ponent (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).
