问题
I am trying to copy a CImage so that I can do some manipulation with it's pixels. I've tried this where source is a pointer to a loaded CImage object.
CImage* dest = new CImage(*source);
However this doesn't seem to work and I believe source and dest are pointing to the same memory.
How would I create a new copy totally detached from the previous CImage?

If this is a question about MFC/ATL CImage then you can create new instance and use Create to initialize it to the size of the original CImage. Then use BitBlt to copy contents.
