public RasterImage ImageRegion {get;}

'Declaration
 
Public ReadOnly Property ImageRegion As RasterImage

'Usage
 
Dim instance As LineRemoveCommand
Dim value As RasterImage
 
value = instance.ImageRegion

public RasterImage ImageRegion {get;}

@property (nonatomic, strong, readonly) LTRasterImage* imageRegion;

public RasterImage getImageRegion()

 get_ImageRegion();

public:
property RasterImage^ ImageRegion {
   RasterImage^ get();
}

Property Value

The Leadtools.RasterImage object, updated with a shallow copy of the image that has a region that contains the removed lines.

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