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 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).

SEE ALSO
       SDL_GetRGB, SDL_MapRGB, SDL_MapRGBA, SDL_PixelFormat
