ExponentialEase Class

Definition

Represents an easing function that creates an animation that accelerates and/or decelerates using an exponential formula.

Equivalent WinUI class: Microsoft.UI.Xaml.Media.Animation.ExponentialEase.

Examples

This XAML example applies a ExponentialEase easing function to a DoubleAnimation to create a decelerating animation.

<StackPanel x:Name="LayoutRoot" >
    <StackPanel.Resources>
        <Storyboard x:Name="myStoryboard">
            <DoubleAnimation From="1" To="6" Duration="00:00:3" 
                Storyboard.TargetName="rectScaleTransform" 
                Storyboard.TargetProperty="ScaleY">
                <DoubleAnimation.EasingFunction>
                    <ExponentialEase Exponent="6" EasingMode="EaseOut"/>
                </DoubleAnimation.EasingFunction>
            </DoubleAnimation>
        </Storyboard>
    </StackPanel.Resources>

    <Rectangle PointerPressed="Pointer_Clicked" 
     Fill="Blue" Width="200" Height="30">
        <Rectangle.RenderTransform>
            <ScaleTransform x:Name="rectScaleTransform" />
        </Rectangle.RenderTransform>
    </Rectangle>

    </StackPanel>
// When the user clicks the rectangle, the animation
// begins. 
private void Pointer_Clicked(object sender, PointerRoutedEventArgs e)
{
    myStoryboard.Begin();
}
' When the user clicks the rectangle, the animation
' begins. 
Private Sub Pointer_Clicked(ByVal sender As Object, ByVal e As PointerRoutedEventArgs)
    myStoryboard.Begin()
End Sub

Remarks

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.

Constructors

ExponentialEase()

Initializes a new instance of the ExponentialEase class.

Equivalent WinUI constructor: Microsoft.UI.Xaml.Media.Animation.ExponentialEase.ExponentialEase.

Properties

Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

Equivalent WinUI property: Microsoft.UI.Xaml.DependencyObject.Dispatcher.

(Inherited from DependencyObject)
EasingMode

Gets or sets a value that specifies how the animation interpolates.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.Animation.EasingFunctionBase.EasingMode.

(Inherited from EasingFunctionBase)
Exponent

Gets or sets the exponent used to determine the interpolation of the animation.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.Animation.ExponentialEase.Exponent.

ExponentProperty

Identifies the Exponent  dependency property.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.Animation.ExponentialEase.ExponentProperty.

Methods

ClearValue(DependencyProperty)

Clears the local value of a dependency property.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ClearValue.

(Inherited from DependencyObject)
Ease(Double)

Transforms normalized time to control the pace of an animation.

Equivalent WinUI method: Microsoft.UI.Xaml.Media.Animation.EasingFunctionBase.Ease.

(Inherited from EasingFunctionBase)
GetAnimationBaseValue(DependencyProperty)

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetAnimationBaseValue.

(Inherited from DependencyObject)
GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetValue.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ReadLocalValue.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.RegisterPropertyChangedCallback.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property on a DependencyObject.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.SetValue.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.UnregisterPropertyChangedCallback.
