using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void UnsharpMaskCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   UnsharpMaskCommand command = new UnsharpMaskCommand(); 
   command.Amount = 200; 
   command.Radius = 15; 
   command.Threshold = 50; 
   command.ColorType = UnsharpMaskCommandColorType.Rgb; 
   command.Run(image);
