| 2年前，我提供了一个GIF4J的可用版，GIF4J是一套针对gif操作的Java类库。周末无聊，在Timiil Cracker的悉心指导下，我连续破解了JCAPI和Gif4J。

Usage: java GifImageWatermarkExample [PathToGifImageToWatermark] (please be sure that the gif4j jar is in your CLASSPATH)

By default the gif4j_logotype.gif as an example gif image is used

load and decode gif image
GifImage gifImage

change out directory if it is necessary

create watermark image using TextPainter

//
create watermark
Watermark watermark
