The device coordinates are the ones that were in effect at the time the Windows region was created.

If you want to assign a region from one bitmap to another, you must use the LBitmapRgn::GetRgnHandle function to get region from the first bitmap; then use the LBitmapRgn::SetRgnHandle function to assign the region to the second bitmap.

To update an existing region, you specify how the new region is to be combined with the existing one. For descriptions of the possibilities, refer to Creating a Bitmap Region.
