/** @property */ public Point get_Point () /** @property */ public void set_Point (Point value)
Property ValueThe point to which the arc is drawn. The default value is (0,0).
If the arc segment's start point and end point are the same, no arc is drawn.
Of the four candidate arc sweeps, two represent large arcs with sweeps of 180 degrees or greater, and two represent smaller arcs with sweeps 180 degrees or less. If IsLargeArc is true, then one of the two larger arc sweeps is chosen; otherwise, if is false, one of the smaller arc sweeps is chosen. The remaining two arc candidates are each drawn in a different direction: Counterclockwise or Clockwise. The SweepDirection property specifies which one to use.
The following illustration shows several elliptical arcs that are identical except for their Point settings.
Several ArcSegment objects with different Point settings
In the following examples, an elliptical arc is drawn from (10,100) to (200,100). The arc has a Size of 100 by 50 device-independent pixels, a RotationAngle of 45 degrees, an IsLargeArc setting of true, and a SweepDirection of Counterclockwise.
In Extensible Application Markup Language (XAML), you can use attribute syntax to describe a path.
In XAML, you can also draw an elliptical arc by explicitly using object tags. The following is equivalent to the preceding XAML markup.
<Path Stroke="Black" StrokeThickness="1"> <Path.Data> <PathGeometry> <PathGeometry.Figures> <PathFigureCollection> <PathFigure StartPoint="10,100"> <PathFigure.Segments> <PathSegmentCollection> <ArcSegment Size="100,50" RotationAngle="45" IsLargeArc="True" SweepDirection="CounterClockwise" Point="200,100" /> </PathSegmentCollection> </PathFigure.Segments> </PathFigure> </PathFigureCollection> </PathGeometry.Figures> </PathGeometry> </Path.Data> </Path>
