KeyFrameAnimation KeyFrameAnimation KeyFrameAnimation KeyFrameAnimation Class

Definition

A time-based animation with one or more key frames. These frames are markers, allowing developers to specify values at specific times for the animating property. KeyFrame animations can be further customized by specifying how the animation interpolates between keyframes.

Remarks

An animation is associated with an object's property by calling CompositionObject.StartAnimation and specifying the property name and the animation. See the remarks section of CompositionObject.StartAnimation for a list of animatable properties. See Composition Animations Overview for additional information on ExpressionAnimation s.

A KeyFrameAnimation does not stop automatically when an app's process is suspended. You must subscribe to app state events and stop or pause your animations before the app is suspended. For more info about app suspension, see App lifecycle.

Properties

Comment Comment Comment Comment

A string to associate with the CompositionObject.

(Inherited from CompositionObject)
Compositor Compositor Compositor Compositor

The Compositor used to create this CompositionObject.

(Inherited from CompositionObject)
DelayBehavior DelayBehavior DelayBehavior DelayBehavior

The delay behavior of the key frame animation.

DelayTime DelayTime DelayTime DelayTime

Delay before the animation starts after CompositionObject.StartAnimation is called.

Direction Direction Direction Direction

The direction the animation is playing.

The Direction property allows you to drive your animation from start to end or end to start or alternate between start and end or end to start if animation has an IterationCount greater than one. This gives an easy way for customizing animation definitions.

Dispatcher Dispatcher Dispatcher Dispatcher

The dispatcher for the CompositionObject.
