Represents an easing function that creates an animation that accelerates and/or decelerates using an exponential formula.
The ExponentialEase class has these types of members:
The ExponentialEase class has these constructors.
|ExponentialEase||Initializes a new instance of the ExponentialEase class.|
The ExponentialEase class has these methods. It also inherits methods from the Object class.
|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)|
|GetAnimationBaseValue||Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)|
|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)|
The ExponentialEase class has these properties.
|Read-only||Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)|
|Read/write||Gets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase)|
|Read/write||Gets or sets the exponent used to determine the interpolation of the animation.|
|Read-only||Identifies the Exponent dependency property.|
ExponentialEase is an easing function that has a function-over-time formula that uses an Exponent value to shape the function-over-time curve. The value used for Exponent changes the shape of the curve quite a bit. Exponent can be negative, if so the function acts a bit like changing the EasingMode to EaseOut with a positive value. You might want to experiment with different values for Exponent and EasingMode when using this easing function.
An easing function can be applied to the EasingFunction properties of From/To/By animations, or to the EasingFunction properties of key-frame types used for the Easing variants of key-frame animations. For more info, see Key-frame animations and easing function animations.
This XAML example applies a ExponentialEase easing function to a DoubleAnimation to create a decelerating animation.
