Here’s a free implementation of an animated GIF encoder for Java ME. This class is actually a porting of the original Java version, available here.

Usage is quite straightforward, and it requires these steps:

  1. Instantiate your AnimatedGifEncoder object
  2. Start it, by passing an OutputStream as argument (e.g.: a ByteArrayOutputStream)
  3. Add your Image objects by using addFrame() method
  4. Finalize it by calling finish()
ByteArrayOutputStream bos = new ByteArrayOutputStream();
AnimatedGifEncoder encoder = new AnimatedGifEncoder();
return bos.toByteArray();

As for the original version, code is free for any kind of usages, but you must refer to the Unisys LZW patent for restrictions on use of the associated LZWEncoder class.
