Syntax


public ref class SineEase sealed : EasingFunctionBase

Members

The SineEase class has these types of members:

Constructors

The SineEase class has these constructors.

ConstructorDescription
SineEase Initializes a new instance of the SineEase class.

 

Methods

The SineEase 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)
RegisterPropertyChangedCallback Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

 

Properties

The SineEase class has these properties.

PropertyAccess typeDescription

Dispatcher

Read-only

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. (Inherited from DependencyObject)

EasingMode

Read/write

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

 

Remarks

SineEase is an easing function that has a function-over-time formula that resembles a sine curve when represented as a function-time graph. When EasingMode is EaseIn (the default), this easing function starts slow and accelerates gradually as it reaches the end. It reaches about 30% value halfway through the duration.

The formula used for this function is:

Formula of f(t) equals 1 minus sin times (1-t) times Pi over 2

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 SineEase 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>
                    <SineEase 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>
