public void LineRemoveCommandEventArgsExample() 
{ 
   // 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.UseGap | LineRemoveCommandFlags.CallBackRegion, 200, 5, 7, 10, 2, 2, LineRemoveCommandType.Horizontal); 
   command.LineRemove += new EventHandler<LineRemoveCommandEventArgs>(LineRemoveEvent_S4); 
   command.Run(image); 
 
} 
 
private void LineRemoveEvent_S4(object sender, LineRemoveCommandEventArgs e) 
{ 
   LineRemoveCommandEventArgs ee = new LineRemoveCommandEventArgs(e.Image, e.Region, e.StartRow, e.StartColumn, e.Length); 
   e.Status = RemoveStatus.Remove; 
   if (e.Region != null) 
      e.Image.SetRegion(null, e.Region, RasterRegionCombineMode.AndNotRegion);
