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. |
