using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ObjectInformationCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   //Get the objects center of mass and it's roundness. I am not interested in the axis' orientation, so I pass NULL_ 
   ObjectInformationCommand command = new ObjectInformationCommand(false); 
   command.Run(image); 
 
   MessageBox.Show("Angle = " + command.Angle + "\n" + 
      "Roundness = " + command.Roundness + "\n" + 
      "X = " + command.CenterOfMass.X + "\n" + 
      "Y = " + command.CenterOfMass.Y); 
 
}
