    Remarks

    The Magnifier can be added to any element that is of type UIElement. This is done by using the MagnifierManager. Simply set the MagnifierManager.Magnifier property to the toolkit's Magnifier instance.

    Example
    The following example adds a Magnifier to the parent grid of a Window. Everything contained in Grid can be magnified.
    <Window x:Class="WPFToolkit.Extended.Samples.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
            Title="MainWindow" Height="350" Width="525" >
        <Grid>
            <xctk:MagnifierManager.Magnifier>
                <xctk:Magnifier Radius="100" ZoomFactor=".4" />
            </xctk:MagnifierManager.Magnifier>
            <RichTextBox />
        </Grid>
    </Window>
    The following attaches a Magnifier to a Grid using a Radius of 75, a red boder that is 1 pixel thick, and a ZoomFactor of 0.3526.
    <Window x:Class="WPFToolkit.Extended.Samples.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
            Title="MainWindow" Height="350" Width="525" >
        <Grid>
            <xctk:MagnifierManager.Magnifier>
                <xctk:Magnifier BorderBrush="Red"
                                      BorderThickness="1"
                                      Radius="75" 
                                      ZoomFactor=".3526" />
            </xctk:MagnifierManager.Magnifier>
            <RichTextBox />
        </Grid>
    </Window>
