Remarks

DoubleKeyFrame is an abstract class that defines Double value type key frames for several different techniques of key frame animation: DiscreteDoubleKeyFrame, EasingDoubleKeyFrame, LinearDoubleKeyFrame, SplineDoubleKeyFrame. To animate a Double with key frames, you define a DoubleAnimationUsingKeyFrames animation, and populate its KeyFrames property with one or more DiscreteDoubleKeyFrame, EasingDoubleKeyFrame, LinearDoubleKeyFrame, or SplineDoubleKeyFrame elements that define the key frames.

For more information, see the following DoubleKeyFrame derived objects: DiscreteDoubleKeyFrame, EasingDoubleKeyFrame, LinearDoubleKeyFrame, SplineDoubleKeyFrame.
