QuarticEase Class
Definition
Represents an easing function that creates an animation that accelerates and/or decelerates using the formula f (t) = t4.
Equivalent WinUI class: Microsoft.UI.Xaml.Media.Animation.QuarticEase.

Examples
This XAML example applies a QuarticEase 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>
<QuarticEase 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
QuarticEase has the same behavior as does a PowerEase with Power value of 4. When EasingMode is EaseIn (the default), this easing function starts slow, remains fairly slow for most of the duration, and accelerates rapidly near the end of the duration time.
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
| QuarticEase() |
Initializes a new instance of the QuarticEase class. Equivalent WinUI constructor: Microsoft.UI.Xaml.Media.Animation.QuarticEase.QuarticEase. |
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) |
