CircleEasingFunction Class

Definition

Namespace:

Microsoft.UI.Composition

Represents an easing function that creates an animation that accelerates and/or decelerates using a circular function.

Remarks

You can control whether the animation accelerates, decelerates, or both by specifying the Mode property value on an animation. The following graph demonstrates the different values of Mode, where f(t) represents the animation progress and t represents time.

The formula used for this function is the following.

The valid values for t are -1 <= t <= 1. Values greater than 1 are evaluated as 1, and values less than -1 are evaluated as -1. This means that for values outside this interval, the animation continues, but the easing function pauses when it enters the invalid domain, and it resumes after it leaves the invalid domain.

There are several other easing functions besides CircleEasingFunction. In addition to using the easing functions included in the run-time, you can create your own custom easing functions by inheriting from CompositionEasingFunction.

Properties

Comment	A string to associate with the CompositionObject. (Inherited from CompositionObject)
Compositor	The Compositor used to create this CompositionObject. (Inherited from CompositionObject)
DispatcherQueue	Gets the DispatcherQueue for the CompositionObject. (Inherited from CompositionObject)
ImplicitAnimations	The collection of implicit animations attached to this object. (Inherited from CompositionObject)
Mode	Gets or sets a value that specifies how the animation interpolates.
Properties	The collection of properties associated with the CompositionObject. (Inherited from CompositionObject)

Methods

Close()	Closes the CompositionObject and releases system resources. (Inherited from CompositionObject)
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from CompositionObject)
PopulatePropertyInfo(String, AnimationPropertyInfo)	Defines a property that can be animated. (Inherited from CompositionObject)
StartAnimation(String, CompositionAnimation, AnimationController)	Connects an animation with the specified property of the object and starts the animation. (Inherited from CompositionObject)
StartAnimation(String, CompositionAnimation)	Connects an animation with the specified property of the object and starts the animation. (Inherited from CompositionObject)
StartAnimationGroup(ICompositionAnimationBase)	Starts an animation group. The StartAnimationGroup method on CompositionObject lets you start CompositionAnimationGroup. All the animations in the group will be started at the same time on the object. (Inherited from CompositionObject)
StopAnimation(String)	Disconnects an animation from the specified property and stops the animation. (Inherited from CompositionObject)
StopAnimationGroup(ICompositionAnimationBase)	Stops an animation group. (Inherited from CompositionObject)
TryGetAnimationController(String)	Returns an AnimationController for the animation running on the specified property. (Inherited from CompositionObject)
