Gets or set a framework element to apply a transition to it. This is a dependency property.
The brush for the shadow for the frame that you add to the ImageViewer or RasterImageViewer control.
No need to set this property if you want to apply a transition to a Leadtools.Windows.Controls.ImageViewer. When set the Leadtools.Windows.Controls.ImageViewer.Transition property the TargetObject will be set internally.
For an example, refer to OutBrush.
