Public ReadOnly Property ImageRegion As RasterImage
public:
property RasterImage^ ImageRegion {
RasterImage^ get();
}
A shallow copy of the image that also has a region that contains the hole punches.
If HolePunchRemoveCommandFlags.SingleRegion| HolePunchRemoveCommandFlags.LeadRegion has been set in the Flags property, then when HolePunchRemoveCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the hole punches. So set Flags to HolePunchRemoveCommandFlags.SingleRegion| HolePunchRemoveCommandFlags.LeadRegion. It is the programmer's responsibility to dispose of the region when it is no longer needed.
Run the HolePunchRemoveCommand on an image.
