How can I create animated gif in Java?

问题

I would like to create a gif image from the set of BufferedImages. How can I do this? Is there such library in pure Java (ImageMagick is not an option)? I've found Gif4J library but it's not royality-free.

I just answer a similar question here, but I think that my solution can help.

'ImageIcon' class allows you to load gif animations. I load the image with 'getResource()'. For doing this I normally us URL class to pass the file path. The path does not need to be necessary in a remote machine as the name URL may suggest.

URL url = This.class.getResource(path);
Icon myImgIcon = new ImageIcon(url);
JLabel imageLbl = new JLabel(myImgIcon);
component.add(imageLbl, BorderLayout.CENTER);

path will be the path of the gif inside of the class folder.

There is an image processing library, akin to Picasso which uses the very same AnimatedGifEncoder class mentioned by Lifelogger- Glide Docs, Glide

 AnimatedGifEncoder e = new AnimatedGifEncoder();
 e.start(outputFileName);
 e.setDelay(1000);   // 1 frame per sec
 e.addFrame(image1);
 e.addFrame(image2);
 e.finish();
