Recently, you need to write a picture batch software. Use ImageIO to easily process JPG, however, ImageIO cannot process GIF images. I found a product: www.gif4j.com, but unfortunately, the trial version will play a "gif4j eval" logo for each picture, very disgusting. So I used the source code, and handled the watermark module Watermark.class, I hope gif4j.com don't mind :) Friends who need to use can send me an email: openssl@126.com
