ColorAnimationBase Class

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

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

public abstract class ColorAnimationBase : 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 ColorAnimationUsingKeyFrames class using Extensible Application Markup Language (XAML).

                  a smooth, linear animation between values. -->
                  <LinearColorKeyFrame Value="Red" KeyTime="0:0:2" />

                  <!-- In the next half second, go to yellow. DiscreteColorKeyFrame creates a 
                  sudden jump between values. -->
                  <DiscreteColorKeyFrame Value="Yellow" KeyTime="0:0:2.5" />

                  <!-- In the final 2 seconds of the animation, go from yellow back to green. SplineColorKeyFrame 
                  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.-->
                  <SplineColorKeyFrame Value="Green" KeyTime="0:0:4.5" KeySpline="0.6,0.0 0.9,0.00" />

        This example shows how to use the ColorAnimationUsingKeyFrames to create
        an animation on the BorderBrush property of a Border.
