PointKeyFrame Class

PointKeyFrame Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Defines an animation segment with its own target value and interpolation method for a PointAnimationUsingKeyFrames.

Namespace:  System.Windows.Media.Animation
Assembly:  System.Windows (in System.Windows.dll)

public abstract class PointKeyFrame : DependencyObject

The PointKeyFrame type exposes the following members.

Protected methodPointKeyFrameInitializes a new instance of the PointKeyFrame class.

Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyKeyTimeGets or sets the time at which the key frame's target Value should be reached.
Public propertyValueGets or sets the key frame's target value.

Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public fieldStatic memberKeyTimePropertyIdentifies the KeyTime dependency property.
Public fieldStatic memberValuePropertyIdentifies the Value dependency property.

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.
