SizeAnimationBase Class
.NET Framework 3.0
Abstract class that, when implemented, animates a Size value.
Namespace: System.Windows.Media.Animation

Notes to Inheritors:
See the Custom Animations Overview for information about extending animation classes.
The following code example demonstrates how to use the derived SizeAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).
