How to generate dynamic GIF images in Java

Examples of generating GIF images are not found on the Internet. However, many watermark files are generated. If we make GIF images into watermarks, the images will not move. So I wrote a small example for your reference. (If you want to print a dynamic icon on an image, this class can be well implemented, provided that you must first break down the dynamic icon into several separate GIF images. Of course, you can use a program .)

To useThe animatedgifencoder class is automatically downloaded.
