public interface Reader
Implementations of this interface can decode an image of a barcode in some format into
the String it encodes. For example, QRCodeReader can
decode a QR code. The decoder may optionally receive hints from the caller which may help
it decode more quickly or accurately.
See MultiFormatReader, which attempts to determine what barcode
format is present within the image as well, and then decodes it accordingly.
