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.

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 classMfCmd
-
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 classMfCmd
-
getInstance
public MfCmd getInstance()
Creates a empty unintialized copy of this command implementation.- Specified by:
getInstance
in classMfCmd
- Returns:
- a new instance of the command.
-
replay
public void replay(WmfFile file)
Replays the command on the given WmfFile.
-
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 classMfCmd
- Returns:
- the function identifier.
-
getBounds
public Rectangle getBounds()
-
getScaledBounds
public Rectangle getScaledBounds()
-
setBounds
public void setBounds(int x, int y, int width, int height)
-
setStartingIntersection
public void setStartingIntersection(int x, int y)
-
getStartingIntersection
public Point getStartingIntersection()
-
getScaledStartingIntersection
public Point getScaledStartingIntersection()
-
setEndingIntersection
public void setEndingIntersection(int x, int y)
-
getEndingIntersection
public Point getEndingIntersection()
-
getScaledEndingIntersection
public 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.
-
getRecord
public MfRecord getRecord()
Creates a new record based on the data stored in the MfCommand.
