逆天通用水印扩展篇~新增剪贴板系列的功能和手动配置，卸除原基础不常用的功能：http://www.cnblogs.com/dunitian/p/5377097.html

好几天没上QQ了，今天上了个QQ，，额....额...貌似消息还挺多，没及时回复的还请见谅~~刚好昨天无聊把水印这快封装出来了，支持图片水印，文字水印，索引图水印和非索引图水印，支持位置选择（9个位置 ==》[X]）。好吧不高兴屁话了，软件是WPF的（只满足我的需求，如果有需要可以出第个二版本），水印核心代码封装了个Helper类（通用：支持Winform，WPF，Web，WP，Win10）软件共享一下==>http://pan.baidu.com/s/1qWDwv4C 源码看下面
