PowerEase.Power Property

Gets or sets the exponential power of the animation interpolation. For example, a value of 7 creates an animation interpolation curve that follows the formula f(t) = t7.

Namespace:  System.Windows.Media.Animation
Assembly:  System.Windows (in System.Windows.dll)

'Declaration
Public Property Power As Double
<PowerEase Power="double" .../>

Property Value

Type: System.Double
The exponential power of the animation interpolation. This value must be greater or equal to 0. The default is 2.

Dependency property identifier field: PowerProperty

The following example applies a PowerEase easing function with a Power property value of 20 to a DoubleAnimation to create a decelerating animation. Because the Power value is so high, the deceleration is sudden compared to if you used a lower value.
