            // * RotationCorrection   e.g BarcodeReader.BarcodeRotationCorrection.Extreme  un-rotates and removes perspective from barcode images.
            // * ImageCorrection      e.g BarcodeReader.BarcodeImageCorrection.DeepCleanPixels  separates Barcodes from background imagery and digital noise.
            // * BarcodeEncoding      e.g. BarcodeEncoding.Code128  Setting a specific Barcode format improves speed and reduces the risk of false positive results
