For most elliptical arcs of a particular position, size, and rotation, there are four different arcs that can be drawn; the largeArc and sweepDirection parameters indicate which arc to use.
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 largeArc is true, then one of the two larger arc sweeps is chosen; otherwise, if largeArc is false, one of the smaller arc sweeps is chosen.
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.xaml
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>
This example is part of a larger sample. For the complete sample, see the Geometries Sample.
