推荐答案

位图在内存中有两种方式:DDB和DIB，
DDB不能获取图像的内容，DIB可以做到.
也许您没有提供有关您的问题的足够信息！

there are two ways bitmap in meory : DDB and DIB,
DDB you can''t get contents of image, DIB you can do it.
and maybe you doesn''t provide enough information about your qestion!

看看GetDIBits [

Have a look at the GetDIBits[^] function to see how to get comparable image data.
