IXRDiscretePointKeyFrame (Windows Embedded CE 6.0)

1/6/2010

This class defines an animation segment that uses discrete frames to animate from the x-y point values of the previous key frame to its own x-y point values.

Syntax

class IXRDiscretePointKeyFrame : public IXRPointKeyFrame

Methods

IXRDiscretePointKeyFrame defines no new methods. It inherits its methods from IXRPointKeyFrame.

Remarks

This class animates x-y point values along a set of key frames by using an IXRColorKeyFrameCollection that belongs to an IXRColorAnimationUsingKeyFrames object.

A key frame defines a segment of the IXRColorAnimationUsingKeyFrames object that it belongs to. Each key frame has target x-y point values 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 values of the previous key frame to its own target values. It starts when the previous key frame ends, and it ends when its own key-time is reached.

Discrete key frames like IXRDiscreteColorKeyFrame do not interpolate between x-y point values, instead jumping suddenly to the new target value when the key-time of the key frame is reached.

You can also define a discrete 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 element in the source XAML for your application, see this Microsoft Web site.
