Region Property

Summary

Gets the handle to a LEADTOOLS RasterRegion.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterRegion Region { get; }

@property (nonatomic, strong, readonly, nullable) LTRasterRegion *region;

public RasterRegion getRegion();

public: 
property RasterRegion^ Region { 
   RasterRegion^ get(); 
}

Region # get  (BorderRemoveCommand)

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 of this region when the region is no longer needed.

Example

Run the BorderRemoveCommand on an image.
