public class MfCmdArc
extends MfCmd

The Arc function draws an elliptical arc.

The points (nLeftRect, nTopRect) and (nRightRect, nBottomRect) specify the bounding rectangle. An ellipse formed by the specified bounding rectangle defines the curve of the arc. The arc extends in the current drawing direction from the point where it intersects the radial from the center of the bounding rectangle to the (nXStartArc, nYStartArc) point. The arc ends where it intersects the radial from the center of the bounding rectangle to the (nXEndArc, nYEndArc) point. If the starting point and ending point are the same, a complete ellipse is drawn.

The arc is drawn using the current pen; it is not filled.

MfCmdArc

public MfCmdArc()
Method Detail

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 x scale has changed and the internal coordinate values have to be adjusted.

Specified by:
scaleYChanged in class MfCmd

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.

replay

public void replay(WmfFile file)
Replays the command on the given WmfFile.

Specified by:
replay in class MfCmd
Parameters:
file - the meta file.

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.

getBounds

public java.awt.Rectangle getBounds()

getScaledBounds

public java.awt.Rectangle getScaledBounds()

setBounds

public void setBounds(int x,
                      int y,
                      int width,
                      int height)

setStartingIntersection

public void setStartingIntersection(int x,
                                    int y)

getStartingIntersection

public java.awt.Point getStartingIntersection()

getScaledStartingIntersection

public java.awt.Point getScaledStartingIntersection()

setEndingIntersection

public void setEndingIntersection(int x,
                                  int y)

getEndingIntersection

public java.awt.Point getEndingIntersection()

getScaledEndingIntersection

public java.awt.Point getScaledEndingIntersection()

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()
Creates a new record based on the data stored in the MfCommand.

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

toString

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