   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "clean.tif")); 
 
   // Prepare the command 
   SmoothCommand command = new SmoothCommand(); 
   command.Smooth += new EventHandler<SmoothCommandEventArgs>(SmoothEventExample_S1); 
   command.Flags = SmoothCommandFlags.FavorLong; 
   command.Length = 2; 
 
   command.Run(image); 
 
} 
 
private void SmoothEventExample_S1(object sender, SmoothCommandEventArgs e)
