RasterImage object that is updated with a shallow copy of image that also has a region that contains the removed borders.
public RasterImage ImageRegion { get; }
Public ReadOnly Property ImageRegion As RasterImage
@property (nonatomic, strong, readonly, nullable) LTRasterImage *imageRegion
public RasterImage getImageRegion()
public:
property RasterImage^ ImageRegion {
RasterImage^ get();
}
If BorderRemoveCommandFlags.SingleRegion| BorderRemoveCommandFlags.LeadRegion have been set in Flags, then when BorderRemoveCommand returns, this is updated with a shallow copy of image that also has a region that contains the removed borders. So set Flags to (BorderRemoveCommandFlags.SingleRegion| BorderRemoveCommandFlags.LeadRegion). It is the programmer's responsibility to dispose the region when it is no longer needed.
Run the BorderRemoveCommand on an image.
