The LEADTOOLS CloudServices RecognitionEngine interface provides a high-level method to extract all barcode information from a file -- this method also allows you to also pass in a list of BarcodeOptions. This method will return an enumerable list of BarcodeData.

Code:


         var inputStream = File.Open(@"leadtools.pdf", FileMode.Open);
         LoadDocumentOptions loadOptions = new LoadDocumentOptions()
         {
            FirstPageNumber = 1,
            LastPageNumber = 1
         };

         RecognitionEngine recognitionEngine = new RecognitionEngine();
         BarcodeEngine barcodeEngine = new BarcodeEngine();
         BarcodeReader reader = barcodeEngine.Reader;
         var options = reader.GetAllDefaultOptions();
         var barcodeInformation = recognitionEngine.ExtractBarcode(inputStream, loadOptions, reader, options, null);
         foreach(var barcode in barcodeInformation)
         {
            Console.WriteLine("Symbology: "+ barcode.Symbology);
            Console.WriteLine("Bounds: "+barcode.Bounds);
            Console.WriteLine("Data: " + barcode.Value);
         }
