using Leadtools.ImageProcessing; 
 
 
public void BarcodeEngine_Example() 
{ 
   string[] imageFileNames = 
   { 
   Path.Combine(LEAD_VARS.ImagesDir, "Barcode1.tif"), 
   Path.Combine(LEAD_VARS.ImagesDir, "Barcode2.tif") 
 }; 
 
   // Create a Barcode engine 
   BarcodeEngine engine = new BarcodeEngine(); 
 
   // Load the image 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      foreach (string imageFileName in imageFileNames) 
      { 
         using (RasterImage image = codecs.Load(imageFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1)) 
         { 
            // Read all the barcodes in this image 
            BarcodeData[] barcodes = engine.Reader.ReadBarcodes(image, LeadRect.Empty, 0, null); 
 
            // Print out the barcodes we found 
            Console.WriteLine("{0} contains {1} barcodes", imageFileName, barcodes.Length); 
            for (int i = 0; i < barcodes.Length; i++) 
            { 
               BarcodeData barcode = barcodes[i]; 
               Console.WriteLine("  {0} - {1} - {2}", i + 1, barcode.Symbology, barcode.Value); 
            } 
            Console.WriteLine("-----------------"); 
         }
