Methods

Methods	Description
IXRColorAnimationUsingKeyFrames::GetKeyFrames	Retrieves the collection of IXRColorKeyFrame objects that define the animation.

Thread Safety

Members of this class are thread safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

IXRColorAnimationUsingKeyFrames stores a collection of IXRColorKeyFrame objects that together define the key frames for the animation. The collection of target values for the key-frame animation is retrieved by the IXRColorAnimationUsingKeyFrames::GetKeyFrames method. Each IXRColorKeyFrame defines a segment of the animation with its own target value and key time. When the animation runs, it progresses from one key value to the next at the specified key times.

There are three kinds of IXRColorKeyFrame derived classes, one for each supported interpolation method: IXRLinearColorKeyFrame, IXRDiscreteColorKeyFrame, and IXRSplineColorKeyFrame.

Unlike an IXRColorAnimation, an IXRColorAnimationUsingKeyFrames can have more than two target values. You can also control the interpolation method of individual IXRColorKeyFrame segments.

You can use the methods inherited from the base class IXRTimeline to define the timeline for this animation.

A collection of timeline objects, including IXRColorAnimationUsingKeyFrames objects, belongs to an IXRStoryboard object.

When you create a class instance, use an IXRColorAnimationUsingKeyFramesPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can also define a key-frames color animation in Microsoft Silverlight 3. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the ColorAnimationUsingKeyFrames Class on MSDN.
