    • encodeHighLevel

      public static String encodeHighLevel(String msg, SymbolShapeHint shape, Dimension minSize, Dimension maxSize)
      Performs message encoding of a DataMatrix message using the algorithm described in annex P of ISO/IEC 16022:2000(E).
      Parameters:
      msg - the message
      shape - requested shape. May be SymbolShapeHint.FORCE_NONE, SymbolShapeHint.FORCE_SQUARE or SymbolShapeHint.FORCE_RECTANGLE.
      minSize - the minimum symbol size constraint or null for no constraint
      maxSize - the maximum symbol size constraint or null for no constraint
      Returns:
      the encoded message (the char values range from 0 to 255)
