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

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void LineRemoveConstructorExample() 
{ 
   // 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); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "CleanAfterLineRemoveConstructor.tif"), RasterImageFormat.Tif, 0); 
   codecs.Dispose(); 
   image.Dispose(); 
          
} 
 
private void LineRemoveEvent_S2(object sender, LineRemoveCommandEventArgs e) 
{ 
   Debug.WriteLine("Row Col " + "( " + e.StartRow.ToString() + ", " + e.StartColumn + " )" + 
      "\n Length " + e.Length.ToString()); 
   e.Status = RemoveStatus.Remove; 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
