            // Limit search to 1-dimensional barcodes only (exclude 2D barcodes to speed up the processing).
            // Change to barcodeReader.BarcodeTypesToFind.SetAll() to scan for all supported 1D and 2D barcode types
            // or select specific type, e.g. barcodeReader.BarcodeTypesToFind.PDF417 = True
