Hi,
I saw (from your posts) that you are using CImage class. So if you need to copy the loaded image to the new one you can use the BitBlt() method of CImage.

Here is the code fragment to create a copy of given original image:

// First load the original image
CImage imageOriginal;
imageOriginal.Load(_T("Here is the path to your original image"));

// Make a copy of the original image
CImage imageNew;
imageNew.Create(imageOriginal.GetWidth(), imageOriginal.GetHeight(), imageOriginal.GetBPP());
imageOriginal.BitBlt(imageNew.GetDC(), CPoint(0,0));
imageNew.ReleaseDC();

// Now imageNew holds the copy of original image
....


The above example makes an exact copy of the loaded image.

If you need to copy the specific part of the loaded image, for instance a rectangular part, then you can use the BitBlt() method again, but this time the code could be something like this:

// First load the original image
CImage imageOriginal;
imageOriginal.Load(_T("Here is the path to your original image"));

// Here is the rect that we will copy from the original image (in this case 1/4 of it)
CRect rectCopy(0, 0, imageOriginal.GetWidth() / 2, imageOriginal.GetHeight() / 2);
	
// Make a copy of the specific part
CImage imageNew;
imageNew.Create(rectCopy.Width(), rectCopy.Height(), imageOriginal.GetBPP());
imageOriginal.BitBlt(imageNew.GetDC(), rectCopy, rectCopy.TopLeft());
imageNew.ReleaseDC();

// Now imageNew holds the copy of the specific part from original image


I hope this helps! Smile | :)
