MfCmdPolygon

public MfCmdPolygon()
Method Detail

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.

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object

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.

getRecord

public MfRecord getRecord()
                   throws RecordCreationException
Creates a new record based on the data stored in the MfCommand.

Specified by:
getRecord in class MfCmd
Returns:
the created record.
RecordCreationException

setPointCount

public void setPointCount(int count)

setPoints

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

getPointsX

public int[] getPointsX()

getPointsY

public int[] getPointsY()

getScaledPointsX

public int[] getScaledPointsX()

getScaledPointsY

public int[] getScaledPointsY()

getPointCount

public int getPointCount()

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.

Specified by:
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.

Specified by:
scaleYChanged in class MfCmd
