How to: Add an Animation Output Value to an Animation Starting Value

This example shows how to add an animation output value to an animation starting value.

Example

The xref:System.Windows.Media.Animation.DoubleAnimation.IsAdditive%2A property specifies whether you want the output value of an animation added to the starting value (base value) of an animated property. You can use the xref:System.Windows.Media.Animation.DoubleAnimation.IsAdditive%2A property with most basic animations and most key frame animations. For more information, see Animation Overview and Key-Frame Animations Overview.

The following example shows the effect of using the xref:System.Windows.Media.Animation.DoubleAnimation.IsAdditive%2A?displayProperty=nameWithType property with xref:System.Windows.Media.Animation.DoubleAnimation and using the xref:System.Windows.Media.Animation.DoubleAnimationUsingKeyFrames.IsAdditive%2A?displayProperty=nameWithType property with xref:System.Windows.Media.Animation.DoubleAnimationUsingKeyFrames.
