Int32AnimationBase Class

Abstract class that, when implemented, animates a Int32 value.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationCore (in PresentationCore.dll)

public abstract class Int32AnimationBase : 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 DoubleAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML), but generically shows how to use other derived classes such as Int32AnimationUsingKeyFrames.

<!-- This example shows how to use the DoubleAnimationUsingKeyFrames to create
an animation on the Canvas.Left attached property of a rectangle. -->
<Page xmlns=""
  WindowTitle="KeyFrame Animations">

  <!-- Key frame animations enable you to create complex animations by specifying multiple destination values
      and controlling the animation's interpolation method. -->
    <!-- The position of this rectangle is animated using a key frame animation. -->
    <Rectangle Name="myRectangle"
        <EventTrigger RoutedEvent="Rectangle.Loaded">
            <Storyboard RepeatBehavior="Forever">

              <!-- Animate Canvas.Left attached property using 3 KeyFrames which animates
                the rectangle along a path. This animation repeats indefinitely. -->

                  <!-- Using a LinearDoubleKeyFrame, the rectangle moves steadily from its
                    starting position to 500 over the first 3 seconds.  -->
                  <LinearDoubleKeyFrame Value="500" KeyTime="0:0:3" />

                  <!-- Using a DiscreteDoubleKeyFrame, the rectangle suddenly appears at 500 after
                    the fourth second of the animation. -->
                  <DiscreteDoubleKeyFrame Value="400" KeyTime="0:0:4" />

                  <!-- Using a SplineDoubleKeyFrame, the rectangle moves back to its starting point. The
                    animation starts out slowly at first and then speeds up. This KeyFrame ends after the 6th
                    second. -->
                  <SplineDoubleKeyFrame KeySpline="0.6,0.0 0.9,0.00" Value="10" KeyTime="0:0:6" />
