Java处理图片缩放，水印的利器 thumbnailator

以前用JimiPro，很弱，这个强大，而且API也不错！

Why Thumbnailator?
Making high-quality thumbnails in Java can be a fairly difficult task.


Learning how to use the Image I/O API, Java 2D API, image processing, image scaling techniques, ... but fear not! Thumbnailator will take care of all those things for you!
