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.
System.Windows::DependencyObject
System.Windows.Media.Animation::PointKeyFrame
System.Windows.Media.Animation::DiscretePointKeyFrame
System.Windows.Media.Animation::EasingPointKeyFrame
System.Windows.Media.Animation::LinearPointKeyFrame
System.Windows.Media.Animation::SplinePointKeyFrame
Assembly: System.Windows (in System.Windows.dll)
The PointKeyFrame type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| KeyTime | Gets or sets the time at which the key frame's target Value should be reached. |
| Value | Gets or sets the key frame's target value. |
| 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 Windows Phone 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.) |
| Name | Description | |
|---|---|---|
  | KeyTimeProperty | Identifies the KeyTime dependency property. |
| ValueProperty | Identifies 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.
