GIF Decoder quelloffen übernommen. Class GifDecoder - Decodes a GIF file into one or more frames.

Example:
   GifDecoder d = new GifDecoder();
   d.read("sample.gif");
   int n = d.getFrameCount();
   for (int i = 0; i < n; i++) {
      BufferedImage frame = d.getFrame(i);  // frame i
      int t = d.getDelay(i);  // display duration of frame in milliseconds
      // do something with frame
   }
