DoubleAnimationBase.GetCurrentValueCore Method (Double, Double, AnimationClock)
Calculates a value that represents the current value of the property being animated, as determined by the host animation.
Assembly: PresentationCore (in PresentationCore.dll)
protected abstract double GetCurrentValueCore( double defaultOriginValue, double defaultDestinationValue, AnimationClock animationClock )
The suggested origin value, used if the animation does not have its own explicitly set start value.
The suggested destination value, used if the animation does not have its own explicitly set end value.
Return ValueType: System.Double
The calculated value of the property, as determined by the current animation.
The value of the defaultOriginValue parameter depends on the animation’s position in the composition chain:
If the animation is in the first position in a composition chain and it replaces another animation, defaultOriginValue is the output of that animation at the time it was replaced.
If the animation is in the first position in a composition chain and no animation exists to replace, defaultOriginValue is the base value of the animated property.
If this animation is not in the first position of a composition chain, then defaultOriginValue is the value that is returned by the previous animation in the composition chain that has an AnimationClock that is not Stopped.
The value of the defaultDestinationValue parameter depends on whether there is a previous property Trigger composition layer.
If there is a previous property Trigger composition layer, defaultDestinationValue is the output from that layer.
If there is no previous composition layer, defaultDestinationValue is the base value of the property that you are animating.
