This class allows you to implement temporary image regions, separate from the image region displayed in the viewer control. The region is the viewer content, not image pixel content. It is a rubberband area for the case where a Create is not specified. The sprite can be moved ver the current image by invoking the Move method and can be pasted into the current image by invoking the Paste method.

Note: This method fails if there is no current region defined.
