Represents an easing function that creates an animation that accelerates and/or decelerates using the formula f(t) = t5.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
Thetype exposes the following members.
|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.)|
|Ease||Transforms normalized time to control the pace of an animation. (Inherited from EasingFunctionBase.)|
|EaseInCore||Provides the logic portion of the easing function that you can override to produce the EaseIn mode of the custom easing function. (Overrides EasingFunctionBase.EaseInCore(Double).)|
|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.)|
You can control whether the animation accelerates, decelerates or both by specifying the EasingMode. The following graph demonstrates the different values of EasingMode where f(t) represents the animation progress and t represents time.
The formula used for this function is the following.
f(t) = t5
You can use PowerEase to create the same behavior as CubicEase, QuadraticEase, QuarticEase, and by using the Power property. For example, if you want to use PowerEase to substitute for CubicEase, specify a Power value of 3.
In addition to using the easing functions included in the run-time, you can create your own custom easing functions by inheriting from EasingFunctionBase.
The following example applies a easing function to a DoubleAnimation to create a decelerating animation.
