How to: Create a GeometryDrawing
This example shows how to create and display a xref:System.Windows.Media.GeometryDrawing. A xref:System.Windows.Media.GeometryDrawing enables you to create shape with a fill and an outline by associating a xref:System.Windows.Media.Pen and a xref:System.Windows.Media.Brush with a xref:System.Windows.Media.Geometry. The xref:System.Windows.Media.GeometryDrawing.Geometry%2A describes the shape's structure, the xref:System.Windows.Media.GeometryDrawing.Brush%2A describes the shape's fill, and the xref:System.Windows.Media.GeometryDrawing.Pen%2A describes the shape's outline.
Example
The following example uses a xref:System.Windows.Media.GeometryDrawing to render a shape. The shape is described by a xref:System.Windows.Media.GeometryGroup and two xref:System.Windows.Media.EllipseGeometry objects. The shape's interior is painted with a xref:System.Windows.Media.LinearGradientBrush and its outline is drawn with a xref:System.Windows.Media.Brushes.Black%2A xref:System.Windows.Media.Pen. The xref:System.Windows.Media.GeometryDrawing is displayed using an xref:System.Windows.Media.ImageDrawing and an xref:System.Windows.Controls.Image element.

The following illustration shows the resulting xref:System.Windows.Media.GeometryDrawing.
To create more complex drawings, you can combine multiple drawing objects into a single composite drawing using a xref:System.Windows.Media.DrawingGroup.
