easeInFraction property, it
then uses uniform (linear) motion through the next phase, and
finally decelerates until the end during the period specified
by the easeOutFraction property.
The easing values for the three phases are calculated such that the behavior of constant acceleration, linear motion, and constant deceleration all occur within the specified duration of the animation.
Strict linear motion can be achieved by setting
easeInFraction and easeOutFraction to 0.0.
Note that if acceleration or
deceleration are not 0.0, then the motion during the middle
phase is not at the same speed as that of pure
linear motion. The middle phase consists of
uniform motion, but the speed of that motion is determined by
the size of that phase relative to the overall animation.

The fraction an animation spent accelerating,
between 0.0 and 1.0.
The values of the easeOutFraction property
and easeInFraction property must satisfy the
equation easeOutFraction + easeInFraction <= 1
where any remaining time is spent in the linear motion phase.
Il valore predefinito è 0.

Calculates the eased fraction value based on the
easeInFraction and easeOutFraction
properties.
If fraction
is less than easeInFraction, it calculates a value
based on accelerating up to the linear motion phase.
If fraction
is greater than easeInFraction and less than
(1-easeOutFraction), it calculates a value based
on the linear motion phase between the easing in and easing out phases.
Otherwise, it calculates a value based on constant deceleration
between the linear motion phase and 0.0.
Parametri
fraction:Number — The elapsed fraction of the animation,
between 0.0 and 1.0..
|
Number — The eased fraction of the animation.
