public static void ReadBarcodeFromPDF(string filename, int pageIndex)
   {
      // generate PDF document
      PDFDocument doc = new PDFDocument(filename);

      // get the page you want to read barcode from
      BasePage page = doc.GetPage(pageIndex);

      // set reader setting
      ReaderSettings setting = new ReaderSettings();
      setting.AddTypesToRead(BarcodeType.Code39);

      // read out barcode information
      Barcode[] barcodes = BarcodeReader.ReadBarcodes(setting, page);

      // output barcode information
      foreach (Barcode barcode in barcodes)
         {
            Console.WriteLine(barcode.DataString);
         }
   }
