public MfCmdPolygon()

Method Details

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.
Overrides:
getFunction in interface MfCmd
Returns:
the function identifier.

getInstance

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

getPointCount

public int getPointCount()

getPointsX

public int[] getPointsX()

getPointsY

public int[] getPointsY()

getRecord

public MfRecord getRecord()
            throws RecordCreationException
Creates a new record based on the data stored in the MfCommand.
Overrides:
getRecord in interface MfCmd
Returns:
the created record.

getScaledPointsX

public int[] getScaledPointsX()

getScaledPointsY

public int[] getScaledPointsY()

replay

public void replay(WmfFile file)
Replays the command on the given WmfFile.
Overrides:
replay in interface MfCmd
Parameters:
file - the meta file.

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.
Overrides:
scaleXChanged in interface 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.
Overrides:
scaleYChanged in interface MfCmd

setPointCount

public void setPointCount(int count)

setPoints

public void setPoints(int[] points_x,
                      int[] points_y)

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.

Overrides:
setRecord in interface MfCmd
Parameters:
record - the raw data that makes up the record.

toString

public String toString()
