A shallow copy of the image that also has a region that contains the removed dots.
If DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion has been set in Flags, then when DotRemoveCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed dots. So set Flags to (DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion). It is the programmer's responsibility to dispose of the region when it is no longer needed.
Run the DotRemoveCommand on an image.
