阅读这篇传奇文章： CxImage

它在图像处理中获取一些细节方面很有用。



如果你有一手COM，你可以尝试： http： //msdn.microsoft.com/en-us/library/windows/desktop/ee690086(v=vs.85).aspx [ ^ ]



如果您从头开始工作：在选择了位图的DC上绘制ppm。因此，在取消选择后，您将在位图中获得ppm并继续。

it served me well in fetching some details in image processing.

if you have a hand on COM you can try: http://msdn.microsoft.com/en-us/library/windows/desktop/ee690086(v=vs.85).aspx[^]

if you work from the scratch: draw the ppm on a DC in which your bitmap is selected. So you have the ppm in the bitmap after deselecting and go on.
