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 component (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).
