Methods

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

You can use this class to animate a color value along a set of key frames by putting it in an IXRColorKeyFrameCollection that belongs to an IXRColorAnimationUsingKeyFrames object.

A key frame defines a segment of the IXRColorAnimationUsingKeyFrames object to which it belongs. Each key frame has a target color value and a key-time. The key-time specifies the time at which the target value of the key frame is reached. A key frame animates from the target value of the previous key frame to its own target value. It starts when the previous key frame ends, and it ends when its own key-time is reached.

Spline key frames like IXRSplineColorKeyFrame create a variable transition between values that is determined by the key spline. You can set the key spline by calling IXRSplineColorKeyFrame::SetKeySpline. Splined interpolation can be used to achieve more realistic timing effects such as acceleration and deceleration.

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

You can also define a spline color key-frame in Microsoft Silverlight 3 XAML. 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 brush in the source XAML for your application, see the SplineColorKeyFrame Class on MSDN.
