QuadraticEase class

Applies to Windows and Windows Phone

Represents an easing function that creates an animation that accelerates and/or decelerates using the formula f(t) = t2

Members

The QuadraticEase class has these types of members:

Constructors

The QuadraticEase class has these constructors.

ConstructorDescription
QuadraticEase Initializes a new instance of the QuadraticEase class.

 

Methods

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

MethodDescription
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 QuadraticEase class has these properties.

PropertyAccess typeDescription

Dispatcher

Read-onlyGets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)

EasingMode

Read/writeGets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase)

 

Remarks

QuadraticEase has the same behavior as does a PowerEase with Power value of 2. When EasingMode is EaseIn (the default), this easing function starts slow, remains fairly slow until about half way through the duration, and accelerates 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

The following example applies a QuadraticEase 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>
                    <QuadraticEase 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>
