-/**
- * This class attempts to decode a barcode from an image, not by scanning the whole image,
- * but by scanning subsets of the image. This is important when there may be multiple barcodes in
- * an image, and detecting a barcode may find parts of multiple barcode and fail to decode
- * (e.g. QR Codes). Instead this scans the four quadrants of the image -- and also the center
- * 'quadrant' to cover the case where a barcode is found in the center.
