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.
[xaml]
In [!INCLUDETLA#tla_xaml], you can use attribute syntax to describe a path.
[!code-xamlGeometrySample#56]
[xaml]
(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 [!INCLUDETLA2#tla_xaml], you can also draw an elliptical arc by explicitly using object tags. The following is equivalent to the preceding [!INCLUDETLA2#tla_xaml] markup.

This example is part of a larger sample. For the complete sample, see the Geometries Sample.
