The RasterImage this method creates.
You can also use the RasterImage(RasterImage) constructor to create an exact copy of an existing RasterImage.
To create a copy of an object while maintaining a progress status, refer to the CloneCommand.
This method copies all the pages and any metadata contained in the RasterImage. To create a copy of only the current active page (no metadata information), use the Clone method.
To clone an image with support for a progress event, refer to CloneCommand.
