My requirement is to create specific region of image (given x,y coordinates & width, height of region of image) from the given IImage.
我可以使用IImage-> Draw(handle，destRect，srcRect)方法绘制drawRegion.但是，我应该能够将此图像保存在另一个IImage对象中，而不仅仅是在屏幕上绘制.
I am able to drawRegion using IImage->Draw(handle, destRect, srcRect) method. However, I should be able to save this image in another IImage object rather than just drawing it on screen.
我尝试使用ExtCreateRegion()，但是无法生成适当的HRGN.另外，请告诉我是否可以从HRGN生成IImage对象.
有人可以尽快帮助我吗?
致谢，

Can anyone help me as soon as possible?
