IXRSplinePointKeyFrame (Windows Embedded CE 6.0)
1/6/2010
This class defines an animation segment that animates from the x-y point value of the previous key frame to its own x-y point value by using splined interpolation.
Syntax
class IXRSplinePointKeyFrame : public IXRPointKeyFrame
Methods
| Method | Description |
|---|---|
Retrieves two control points that define animation progress for this key frame. |
|
Sets two control points that define animation progress for this key frame. |
Remarks
You can use this class to animate the value of an x-y point along a set of key frames by putting it in an IXRPointKeyFrameCollection that belongs to an IXRPointAnimationUsingKeyFrames object.
A key frame defines a segment of the IXRPointAnimationUsingKeyFrames object to which it belongs. Each key frame has a target value for an x,y coordinate 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 IXRSplinePointKeyFrame create a variable transition between values that is determined by the key spline. You can set the key spline by calling IXRSplinePointKeyFrame::SetKeySpline. Splined interpolation can be used to achieve more realistic timing effects such as acceleration and deceleration.
You can also define a spline point key-frame in Microsoft Silverlight 2 XAML. For information about the differences between XAML in Silverlight for Windows Embedded and Silverlight 2, see Differences Between Silverlight for the Web and Silverlight for Windows Embedded. For more information about how to define this brush in the source XAML for your application, see this Microsoft Web site.
