PointAnimationBase Class

Abstract class that, when implemented, animates a Point value.

Namespace: System.Windows.Media.Animation
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public abstract class PointAnimationBase : AnimationTimeline
public abstract class PointAnimationBase extends AnimationTimeline
public abstract class PointAnimationBase extends AnimationTimeline
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Notes to Inheritors: See the Custom Animations Overview for information about extending animation classes.

The following code example demonstrates how to use the derived PointAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).
