      • replay

        public void replay​(WmfFile file)
        Replays the command on the given WmfFile.
        Specified by:
        replay in class MfCmd
        Parameters:
        file - the meta file.

      • getInstance

        public MfCmd getInstance()
        Creates a empty unintialized copy of this command implementation.
        Specified by:
        getInstance in class MfCmd
        Returns:
        a new instance of the command.

      • getFunction

        public int getFunction()
        Reads the function identifier. Every record type is identified by a function number corresponding to one of the Windows GDI functions used.
        Specified by:
        getFunction in class MfCmd
        Returns:
        the function identifier.

      • setRecord

        public void setRecord​(MfRecord record)
        Reads the command data from the given record and adjusts the internal parameters according to the data parsed.

        After the raw record was read from the datasource, the record is parsed by the concrete implementation.

        Specified by:
        setRecord in class MfCmd
        Parameters:
        record - the raw data that makes up the record.

        public int[] getScaledPointsY()

      • scaleXChanged

        protected void scaleXChanged()
        A callback function to inform the object, that the x scale has changed and the internal coordinate values have to be adjusted.

        scaleXChanged in class MfCmd

      • scaleYChanged

        protected void scaleYChanged()
        A callback function to inform the object, that the y scale has changed and the internal coordinate values have to be adjusted.
