EasingPointKeyFrame Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Defines a property that enables you to associate an easing function with a PointAnimationUsingKeyFrames key-frame animation.

The EasingPointKeyFrame type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| EasingFunction | Gets or sets the easing function that is applied to the key frame. |
| KeyTime | Gets or sets the time at which the key frame's target Value should be reached. (Inherited from PointKeyFrame.) |
| Value | Gets or sets the key frame's target value. (Inherited from PointKeyFrame.) |
| Name | Description | |
|---|---|---|
 | CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
| ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetAnimationBaseValue | Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
| SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
The following example shows how to use key frames with easing functions associated with them to create an animation that simulates an oval going up in the air and falling back down, where it bounces to a stop.
