PowerEase.Power Property

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

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

public double Power { get; set; }
<object 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.

<Rectangle Name="myRectangle" Width="200" Height="30" Fill="Blue">
    <Rectangle.Triggers>
        <EventTrigger RoutedEvent="Rectangle.MouseDown">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation From="30" To="200" Duration="00:00:3" 
                     Storyboard.TargetName="myRectangle" 
                     Storyboard.TargetProperty="Height">
                        <DoubleAnimation.EasingFunction>
                            <PowerEase Power="20" EasingMode="EaseOut"/>
                        </DoubleAnimation.EasingFunction>
                    </DoubleAnimation>

                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Rectangle.Triggers>

</Rectangle>
