Locates and decodes a barcode in some format within an image. This method also accepts hints, each possibly associated to some data, which may help the implementation decode.
image of barcode to decode
passed as a {@link Map} from DecodeHintType to arbitrary data. The meaning of the data depends upon the hint type. The implementation may or may not do anything with these hints.
which: string the barcode encodes
Resets any internal state the implementation has after a decode, to prepare it for reuse.
Generated using TypeDoc
Implementations of this interface can decode an image of a barcode in some format into the it: string encodes. For example, {@link com.google.zxing.qrcode.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.
