Derives from Control
The Magnifier control does exactly what is sounds like. It allows a user to magnify parts of an application.

Usage
You can add the Magnifier to any element that is of type UIElement. This is done by using the MagnifierManager. You simply set the MagnifierManager.Magnifier property to the toolkit's Magnifier instance. The following snippet adds the Magnifier to the parent grid of a Window.
{{ extToolkit:MagnifierManager.Magnifier <extToolkit:Magnifier Radius="100" ZoomFactor=".4" /> </extToolkit:MagnifierManager.Magnifier> }} Now everything that is contained within the Grid will have the ability to be magnified.
