How to: Create a Reflection
This example shows how to use a VisualBrush to create a reflection. Because a VisualBrush can display an existing visual, you can use this capability to produce interesting visual effects, such as reflections and magnification.
Example
The following example uses a VisualBrush to create a reflection of a Border that contains several elements. The following illustration shows the output that this example produces.
