Class MfCmdPolyPolygon


public class MfCmdPolyPolygon
extends MfCmd

PolyPolygon, is a list of polygons, for filled polygons SetPolyFillMode affects how the polygon is filled. the number of polygons is recorded, followed by the number of points in each polygon, and then a long sequence of all the points of all the polygons.

Constructor Details

MfCmdPolyPolygon

public MfCmdPolyPolygon()
The default constructor, adjusts the scale to 1.

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.

getPointsX

public int[] getPointsX(int polygon)

getPointsY

public int[] getPointsY(int polygon)

getPolygonCount

public int getPolygonCount()

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(int polygon)

getScaledPointsY

public int[] getScaledPointsY(int polygon)

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

setPoints

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

setPolygonCount

public void setPolygonCount(int count)

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()
