using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void RegionHolesRemovalCommandExample() 
{ 
   // Load an image

   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   LeadRect rcRect = new LeadRect(image.Width / 8, image.Height / 8, image.Width / 2 + image.Width / 8, image.Height / 2 + image.Height / 8); 
   image.AddEllipseToRegion(null, rcRect, RasterRegionCombineMode.SetNot); 
   RegionHolesRemovalCommand command = new RegionHolesRemovalCommand();
