Remarks

Do not implement this interface. Obtain a pointer to an instance of this interface by using the AnimationDescription.Animations property.

The timing controls Control1 and Control2 specify the location of the first and second control points of a cubic Bézier curve. These two points have the same meaning as they do in the CSS transition-timing-function property. Control point zero is always (0,0) and control point three is always (1,1). The coordinates of Control1 and Control2 are always in the range 0 to 1, inclusive.

On the resulting Bézier curve, the x-coordinate represents time and the y-coordinate represents progress. The raw curve from (0,0) to (1,1) is scaled to match the actual duration and range of the animated transition, such that x=0 is the starting time of the transform, x=1 is the ending time, y=0 is the initial value of the animated property, and y=1 is the final value. Values of x and y between 0 and 1 represent corresponding intermediate values of time and the animation.

Properties

Control1	Gets the location of the first control point for the cubic Bézier curve that describes how this property of this object should animate over time.
Control2	Gets the location of the second control point for the cubic Bézier curve that describes how this property of this object should animate over time.
Delay	Gets the amount of time between when the animation is instructed to begin and when that animation actually begins to draw.
Duration	Gets the amount of time over which the animation should be performed. This does not include the delay.
Type	Gets the type of animation represented by this object.
