PowerEase.Power PowerEase.Power PowerEase.Power PowerEase.Power Property

Definition

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.

public:
 property double Power { double get(); void set(double value); };
public double Power { get; set; }
member this.Power : double with get, set
Public Property Power As Double

Property Value

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

Examples

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>
