How to: Create an Elliptical Arc
This example shows how to draw an elliptical arc. To create an elliptical arc, use the xref:System.Windows.Media.PathGeometry, xref:System.Windows.Media.PathFigure, and xref:System.Windows.Media.ArcSegment classes.
Example
In the following examples, an elliptical arc is drawn from (10,100) to (200,100). The arc has a xref:System.Windows.Media.ArcSegment.Size%2A of 100 by 50 device-independent pixels, a xref:System.Windows.Media.ArcSegment.RotationAngle%2A of 45 degrees, an xref:System.Windows.Media.ArcSegment.IsLargeArc%2A setting of true, and a xref:System.Windows.Media.ArcSegment.SweepDirection%2A of xref:System.Windows.Media.SweepDirection.Counterclockwise.
In Extensible Application Markup Language (XAML), you can use attribute syntax to describe a path.
[!code-xamlGeometrySample#56]
(Note that this attribute syntax actually creates a xref:System.Windows.Media.StreamGeometry, a lighter-weight version of a xref:System.Windows.Media.PathGeometry. For more information, see the Path Markup Syntax page.)
In XAML, you can also draw an elliptical arc by explicitly using object tags. The following is equivalent to the preceding XAML markup.
[!code-xamlGeometrySample#36]
This example is part of a larger sample. For the complete sample, see the Geometries Sample.
