public void VignetteCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   VignetteCommand command = new VignetteCommand(); 
   command.Origin = new LeadPoint((image.Width / 2), (image.Height / 2)); 
   command.Fading = 50; 
   command.FadingRate = 100; 
   command.Width = 20; 
   command.Height = 20; 
   command.VignetteColor = new RasterColor(0, 0, 0); 
   command.Flags = VignetteCommandFlags.Ellipse | VignetteCommandFlags.Fillin; 
 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
