SingleAnimationUsingKeyFrames.GetCurrentValueCore Method

  • Reference

Definition

Namespace:
System.Windows.Media.Animation
Assembly:
PresentationCore.dll

Calculates a value that represents the current value of the property being animated, as determined by this instance of SingleAnimationUsingKeyFrames.

protected:
 override float GetCurrentValueCore(float defaultOriginValue, float defaultDestinationValue, System::Windows::Media::Animation::AnimationClock ^ animationClock);
protected override sealed float GetCurrentValueCore (float defaultOriginValue, float defaultDestinationValue, System.Windows.Media.Animation.AnimationClock animationClock);
override this.GetCurrentValueCore : single * single * System.Windows.Media.Animation.AnimationClock -> single
Protected Overrides NotOverridable Function GetCurrentValueCore (defaultOriginValue As Single, defaultDestinationValue As Single, animationClock As AnimationClock) As Single

Parameters

defaultOriginValue
Single

The suggested origin value, used if the animation does not have its own explicitly set start value.

defaultDestinationValue
Single

The suggested destination value, used if the animation does not have its own explicitly set end value.

animationClock
AnimationClock

An AnimationClock that generates the CurrentTime or CurrentProgress used by the host animation.

Returns

Single

The calculated value of the property, as determined by the current instance.

Remarks

If the defaultOriginValue is the first in the composition chain, this value will be the snapshot value (if one is available) or the base property value; otherwise this value will be the value returned by the previous animation in the chain with an AnimationClock that is not Stopped.

The defaultDestinationValue is the base value if the animation is in the first composition layer of animations on a property; otherwise the value is the output value from the previous composition layer of animations for the property.
