Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void HalfTonePatternCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample1.cmp")); 
 
   // Prepare the command 
   HalfTonePatternCommand command = new HalfTonePatternCommand(); 
   command.Contrast = 100; 
   command.Ripple = 200; 
   command.AngleContrast = 12; 
   command.AngleRipple = 2; 
   command.AngleOffset = 4500; 
   command.BackGroundColor = new RasterColor(255, 255, 255); 
   command.ForeGroundColor = new RasterColor(255, 0, 0); 
   command.Type = HalfTonePatternCommandType.Line; 
   command.Run(image);
