Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void FeretsDiameterConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs();

   // Prepare the command 
   LeadRect rcRect = new LeadRect(image.Width / 4, image.Height / 4, image.Width * 3 / 4, image.Height * 3 / 4);

   RegionContourPointsCommand contourcommand = new RegionContourPointsCommand(null);

   } 
 
   FeretsDiameterCommand command = new FeretsDiameterCommand(); 
   command.Points = contourcommand.Points;
