强化JAVA图形操作类

不想再继续为汉语编程的问题浪费时间，印度的SKTN下场怎么样大家一目了然。

而在我Blog发表评论的，只要是用人类语言，我都可以接受。就算有个别不用人类语言的，有空时我也会尽量帮那些生物往人类语言方向矫正。

——————————————————————————————

我们都知道，微软对其原有GDI（Graphics Device Interface）改进后形成了现在的GDI+。作为图形设备接口GDI的继任者，其对GDI的很多功能都进行了优化，而且还提供了许多方便实用的附加功能。

以此为基础，在.Net环境下可以很轻松的完成一系列复杂的图形操作。而与之相较，Java的图像接口在图像处理功能上则略显单薄，而部分操作较之C#等还有些复杂。

所以最近我打算在本人的loonframework项目中将一些java图像接口二次封装，及添加部分新的功能进入。下面我公布的，是一些在Loonframework框架中将新添加的图像处理类。当然，这些还在测试阶段，最后的确定版估计会与此有较大出入，有改进意见的欢迎邮寄到我的Email:ceponline@yahoo.com.cn。（最近挺懒的……一写代码就犯困……下班只看漫画度日……）
