How to: Animate the Position of an Object by Using PointAnimation

  • Article

This example shows how to use the PointAnimation class to animate an object along a Path.

Example

The following example moves an ellipse along a Path from one point on the screen to another. The example animates the position of an EllipseGeometry by using PointAnimation to animate the Center property.

<!-- This example shows how to use PointAnimation to animate the
position of an ellipse by animating the Center property of an 
EllipseGeometry. PointAnimation is used because the Center property
takes a Point value. -->
