Remarks

PointKeyFrame is an abstract class that defines Point value type key frames for several different techniques of key frame animation: DiscretePointKeyFrame, EasingPointKeyFrame, LinearPointKeyFrame, and SplinePointKeyFrame. To animate a Point with key frames, you define a PointAnimationUsingKeyFrames animation and populate its KeyFrames property with one or more DiscretePointKeyFrame, EasingPointKeyFrame, LinearPointKeyFrame, or SplinePointKeyFrame elements that define the key frames.

For more information, see the following PointKeyFrame derived objects: DiscretePointKeyFrame, EasingPointKeyFrame, LinearPointKeyFrame, and SplinePointKeyFrame.
