RectAnimationBase Class

Abstract class that, when implemented, animates a Rect value.

Namespace: System.Windows.Media.Animation
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public abstract class RectAnimationBase : AnimationTimeline
public abstract class RectAnimationBase extends AnimationTimeline
public abstract class RectAnimationBase extends AnimationTimeline
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Notes to Inheritors: See the Custom Animations Overview for information about extending animation classes.

The following code example demonstrates how to use the derived RectAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).

              <!-- Animate the Rect property of the RectangleGeometry which causes the
              rectangle to animate its position as well as its width and height. -->
              <RectAnimationUsingKeyFrames
                Storyboard.TargetName="myRectangleGeometry"
                Storyboard.TargetProperty ="Rect"
                Duration="0:0:6" FillBehavior="HoldEnd" RepeatBehavior="Forever">

                <!-- Animate position, width, and height in first 2 seconds. LinearRectKeyFrame creates
                a smooth, linear animation between values. -->
                <LinearRectKeyFrame Value="600,50,200,50" KeyTime="0:0:2" />

                <!-- In the next half second, change height to 10. DiscreteRectKeyFrame creates a 
                sudden "jump" between values. -->
                <DiscreteRectKeyFrame Value="600,50,200,10" KeyTime="0:0:2.5" />

                <!-- In the final 2 seconds of the animation, go back to the starting position, width, and height.  
                Spline key frames like SplineRectKeyFrame creates a variable transition between values depending 
                on the KeySpline property. In this example, the animation starts off slow but toward the end of 
                the time segment, it speeds up exponentially.-->
                <SplineRectKeyFrame Value="0,200,100,100" KeyTime="0:0:4.5" KeySpline="0.6,0.0 0.9,0.00"  />
