Defines a library of standard transitions.

Inheritance

The IUIAnimationTransitionLibrary interface inherits from the IUnknown interface. IUIAnimationTransitionLibrary also has these types of members:

Methods

The IUIAnimationTransitionLibrary interface has these methods.


IUIAnimationTransitionLibrary::CreateAccelerateDecelerateTransition Creates an accelerate-decelerate transition.
IUIAnimationTransitionLibrary::CreateConstantTransition Creates a constant transition.
IUIAnimationTransitionLibrary::CreateCubicTransition Creates a cubic transition.
IUIAnimationTransitionLibrary::CreateDiscreteTransition Creates a discrete transition.
IUIAnimationTransitionLibrary::CreateInstantaneousTransition Creates an instantaneous transition.
IUIAnimationTransitionLibrary::CreateLinearTransition Creates a linear transition.
IUIAnimationTransitionLibrary::CreateLinearTransitionFromSpeed Creates a linear-speed transition.
IUIAnimationTransitionLibrary::CreateParabolicTransitionFromAcceleration Creates a parabolic-acceleration transition.
IUIAnimationTransitionLibrary::CreateReversalTransition Creates a reversal transition.
IUIAnimationTransitionLibrary::CreateSinusoidalTransitionFromRange Creates a sinusoidal-range transition, with a specified range of oscillation.
IUIAnimationTransitionLibrary::CreateSinusoidalTransitionFromVelocity Creates a sinusoidal-velocity transition, with an amplitude determined by the initial velocity.
IUIAnimationTransitionLibrary::CreateSmoothStopTransition Creates a smooth-stop transition.

Remarks

Windows Animation includes a library of common transitions that developers can apply to variables through a storyboard. The parameters for specifying a transition depend on the type of transition. For some transitions, the duration of the transition is an explicit parameter; for others, the duration is determined by other parameters, such as speed or acceleration when the transition begins. A transition's initial value or velocity can be overridden if a discontinuous jump is desired, and duration can be queried after the transition is added to a storyboard.

If an application requires an effect that cannot be specified using the transition library, developers can implement custom transitions. A custom transition is created by first implementing the interpolator function for the transition, and then by using a factory object to generate transitions from interpolators. An interpolator must implement the IUIAnimationInterpolator interface; an implementation of the transition factory object is provided by UIAnimationTransitionFactory.

Examples

For an example that creates the transition library object, see Create the Main Animation Objects.
