NAME

6       SDL_GetRGBA  - Get RGBA values from a pixel in the specified pixel for‐
7       mat.

SYNOPSIS

10       #include "SDL.h"
11
12       void SDL_GetRGBA(Uint32 pixel, SDL_PixelFormat *fmt,  Uint8  *r,  Uint8
13       *g, Uint8 *b, Uint8 *a);

DESCRIPTION

16       Get  RGBA  component  values from a pixel stored in the specified pixel
17       format.
18
19       This function uses the entire  8-bit  [0..255]  range  when  converting
20       color  components from pixel formats with less than 8-bits per RGB com‐
21       ponent (e.g., a completely white pixel in 16-bit  RGB565  format  would
22       return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).
23
24       If  the  surface  has no alpha component, the alpha will be returned as
25       0xff (100% opaque).
