    • decode

      public Result decode(BinaryBitmap image) throws NotFoundException, FormatException
      Locates and decodes a Data Matrix code in an image.
      Specified by:
      decode in interface Reader
      Parameters:
      image - image of barcode to decode
      Returns:
      a String representing the content encoded by the Data Matrix code
      Throws:
      NotFoundException - if a Data Matrix code cannot be found
      FormatException - if a Data Matrix code cannot be decoded
    • decode

      public Result decode(BinaryBitmap image, Map<DecodeHintType,?> hints) throws NotFoundException, FormatException
      Description copied from interface: Reader
      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.
      Specified by:
      decode in interface Reader
      Parameters:
      image - image of barcode to decode
      hints - passed as a 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.
      Returns:
      String which the barcode encodes
      Throws:
      NotFoundException - if no potential barcode is found
      FormatException - if a potential barcode is found but format is invalid
    • reset

      public void reset()
      Description copied from interface: Reader
      Resets any internal state the implementation has after a decode, to prepare it for reuse.
      Specified by:
      reset in interface Reader
