# 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>.
