public final Result decode(BinaryBitmap image)
throws ReaderException
Reader
decode in interface Readerimage - image of barcode to decode
ReaderException - if the barcode cannot be located or decoded for any reason
public final Result decode(BinaryBitmap image,
Hashtable hints)
throws ReaderException
Reader
decode in interface Readerimage - image of barcode to decodehints - passed as a Hashtable 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.
ReaderException - if the barcode cannot be located or decoded for any reason
public abstract Result decodeRow(int rowNumber,
BitArray row,
Hashtable hints)
throws ReaderException
OneDReaderAttempts to decode a one-dimensional barcode format given a single row of an image.
decodeRow in interface OneDReaderrowNumber - row number from top of the rowrow - the black/white pixel data of the rowhints - decode hints
Result containing encoded string and start/end of barcode
ReaderException - if an error occurs or barcode cannot be found
