Constructors

The QuarticEase class has these constructors.

Constructor	Description
QuarticEase	Initializes a new instance of the QuarticEase class.

Methods

The QuarticEase class has these methods. It also inherits methods from the Object class.

Method	Description
ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject)
Ease	Transforms normalized time to control the pace of an animation. (Inherited from EasingFunctionBase)
GetAnimationBaseValue	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)

Properties

The QuarticEase class has these properties.

Property	Access type	Description
Dispatcher	Read-only	Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)
EasingMode	Read/write	Gets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase)
EasingModeProperty	Read-only	Identifies the EasingMode dependency property. (Inherited from EasingFunctionBase)

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.

Examples

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

XAML


<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();
}
