主要功能是把图片倒置180度。 虽然是简单的功能，但也能体现用VC图像编程的基本方法。-main function is to picture inverted 180 degrees. Although it is simple, functional, but it can also reflect images with VC's basic programming methods.

图像处理编程关于几何变换（平移，转置，倒置，放缩），效果挺好，希望能对您有点帮助。-the code is about gray geometry transformation. the result is good. thanks.
