Region Property

Leadtools.ImageProcessing.Core Namespace > BorderRemoveCommand Class : Region Property



Gets the handle to a LEADTOOLS Leadtools.RasterRegion. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property Region As RasterRegion
Visual Basic (Usage)Copy Code
Dim instance As BorderRemoveCommand
Dim value As RasterRegion
 
value = instance.Region
C# 
public RasterRegion Region {get;}
C++/CLI 
public:
property RasterRegion^ Region {
   RasterRegion^ get();
}

Property Value

Handle to a windows region. When BorderRemoveCommand returns, this is updated with a single windows region corresponding to all changes, only if BorderRemoveCommandFlags.SingleRegion has been set in Flags and BorderRemoveCommandFlags.LeadRegion has not been set. To use this, set the Flags to BorderRemoveCommandFlags.SingleRegion. It is the programmer's responsibility to dispose this region when the region is no longer needed.

Example

Run the BorderRemoveCommand on an image.
