Rotate(旋转)或Flip(翻转)图片，旋转为顺时针,先旋转，再翻转
示例：
[cpp] view plain copy
- static Bitmap orgpic(_T("D:\\1.PNG")) ;
- orgpic.RotateFlip(Rotate180FlipX ) ;
-
- Graphics g(GetDC()->GetSafeHdc()) ;
- RectF destRect(0.0f, 0.0f, orgpic.GetWidth(), orgpic.GetHeight()) ;
- g.DrawImage(&orgpic, destRect,0.0f, 0.0f, orgpic.GetWidth(), orgpic.GetHeight(),UnitPixel) ;
