ByQuadrantReader

class ByQuadrantReader(delegate: Reader) : Reader

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.
