Class YAHOO.util.Easing

Singleton that determines how an animation proceeds from start to end.

Methods

backBoth

Number backBoth ( t , b , c , d , s )
Backtracks slightly, then reverses direction, overshoots end, then reverses and comes back to end.
Parameters:
t <Number> Time value used to compute current value
b <Number> Starting value
c <Number> Delta between start and end values
d <Number> Total length of animation
s <Number> Overshoot (optional)
Returns: Number
The computed value for the current animation frame

backIn
