   // Create an instance of the engine 
   using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD)) 
   { 
      // Start the engine using default parameters 
      ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
 
      // Get the zone manager 
      IOcrZoneManager ocrZoneManager = ocrEngine.ZoneManager; 
 
      // Show all the zone types supported by this engine 
      Console.WriteLine("Hit enter to show the supported zone types"); 
      //Console.ReadLine(); 
 
      OcrZoneType[] zoneTypes = ocrZoneManager.GetSupportedZoneTypes(); 
      Console.WriteLine("Supported zone types:"); 
      Console.WriteLine("---------------------"); 
      foreach (OcrZoneType zoneType in zoneTypes) 
         Console.WriteLine("  {0}", zoneType); 
 
      // Shutdown the engine
