ColorKeyFrame Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Provides a base class for specific animation key-frame techniques that define an animation segment with a Color target value. Derived classes each provide a different key-frame interpolation method for a Color value that is provided for a ColorAnimationUsingKeyFrames animation.

Methods

	Name	Description
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

ColorKeyFrame is an abstract class that defines Color value-type key frames for several different techniques of key-frame animation: DiscreteColorKeyFrame, EasingColorKeyFrame, LinearColorKeyFrame, and SplineColorKeyFrame. To animate a Color with key frames, you define a ColorAnimationUsingKeyFrames animation and populate its KeyFrames property with one or more DiscreteColorKeyFrame, EasingColorKeyFrame, LinearColorKeyFrame, or SplineColorKeyFrame elements that define the key frames.

For more information, see the following ColorKeyFrame derived types: DiscreteColorKeyFrame, EasingColorKeyFrame, LinearColorKeyFrame, and SplineColorKeyFrame.
