Remarks

An AnimationTimeline is a type of Timeline object that generates output values based on its timing progress. All animation types inherit from AnimationTimeline.

Freezable Features: Because it inherits from the Freezable class, the AnimationTimeline class provides several special features: AnimationTimeline objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.

Notes to Inheritors

To create a custom animation, override or implement the following members:

If the class does not use dependency properties to store its data or it requires extra initialization after creation, you might need to override additional methods; see the Freezable Objects Overview for more information.

For more information about creating custom animations, see the Custom Animations Overview.
