这是一个位图操作的类，不依赖于MFC，可以实现位图的旋转、镜像、透明、扭曲等等非常绚丽的特效，非常值得推荐。This a bitmap manipulation class that would not be MFC dependent, and would offer some extended features not present in the original MFC implementation. This class can load any 8, 16, 24 or 32bit bitmap, but internally works with 32bit bitmaps. The results can be saved as the 24bit bitmap on the hard disk, or it can be drawn on the device context (DC).-This is a bitmap type of operation, not dependent on MFC, can be achieved bitmap rotation, mirror, transparent, distortion effects, etc. is very brilliant, very worthy of recommendation.
