   ' Prepare the command
   Dim command As GlassEffectCommand = New GlassEffectCommand
   command.CellWidth = 20
   command.CellHeight = 10
   command.Flags = GlassEffectCommandFlags.WidthFrequency Or GlassEffectCommandFlags.HeightPeriod
   ' Apply glass effect.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void GlassEffectCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   GlassEffectCommand command = new GlassEffectCommand(); 
   command.CellWidth  = 20; 
   command.CellHeight = 10; 
   command.Flags      = GlassEffectCommandFlags.WidthFrequency | GlassEffectCommandFlags.HeightPeriod; 
   // Apply glass effect. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}
