How to: Define a Rectangle Using a RectangleGeometry
This example describes how to use the xref:System.Windows.Media.RectangleGeometry class to describe a rectangle.
Example
The following example shows how to create and render a xref:System.Windows.Media.RectangleGeometry. The relative position and the dimensions of the rectangle are defined by a xref:System.Windows.Rect structure. The relative position is 50,50 and the height and the width are both 25 creating a square. The rectangle's interior is painted with a xref:System.Windows.Media.Brushes.LemonChiffon%2A brush and its outline is painted with a xref:System.Windows.Media.Brushes.Black%2A stroke with a thickness of 1.

RectangleGeometry
Although this example used a xref:System.Windows.Shapes.Path element to render the xref:System.Windows.Media.RectangleGeometry, there are many other ways to use xref:System.Windows.Media.RectangleGeometry objects. For example, a xref:System.Windows.Media.RectangleGeometry can be used to specify the xref:System.Windows.UIElement.Clip%2A of a xref:System.Windows.UIElement or the xref:System.Windows.Media.GeometryDrawing.Geometry%2A of a xref:System.Windows.Media.GeometryDrawing.
Other simple geometry classes include xref:System.Windows.Media.LineGeometry and xref:System.Windows.Media.EllipseGeometry. These geometries, as well as more complex ones, can also be created using a xref:System.Windows.Media.PathGeometry or xref:System.Windows.Media.StreamGeometry.
