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  (LineRemoveCommand)

Property Value

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

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core;

{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand(LineRemoveCommandFlags.UseVariance | LineRemoveCommandFlags.SingleRegion, 200, 5, 7, 10, 2, 2, LineRemoveCommandType.Horizontal); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S2); 
   command.Run(image); 
 
} 
 
private void LineRemoveEvent_S2(object sender, LineRemoveCommandEventArgs e) 
{ 
   MessageBox.Show("Row Col " + "( " + e.StartRow.ToString() + ", " + e.StartColumn + " )" + 
      "\n Length " + e.Length.ToString()); 
   e.Status = RemoveStatus.Remove; 
}
