| Starting with Flex 4.0, Adobe recommends that you use the spark.effects.easing.Linear class as an alternative to this class.
The Spark effects provided as of Flex 4 use classes which implement the
IEaser interface instead of the easing functions in classes like Linear for
the earlier Flex 3 effects. To achieve the same functionality of the old
Linear class, create a new instance of spark.effects.easing.Linear or call
spark.effects.easing.Linear.getInstance() to get a singleton instance.
|
The Linear class defines easing functions to implement
linear motion with Flex effect classes.

public static function easeIn(t:Number, b:Number, c:Number, d:Number):Number
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The easeIn()
method starts motion from zero velocity,
and then accelerates motion as it executes.
Parameters
| t:Number — Specifies time.
|
|
| b:Number — Specifies the initial position of a component.
|
|
| c:Number — Specifies the total change in position of the component.
|
|
| d:Number — Specifies the duration of the effect, in milliseconds.
|
Returns | Number — Number corresponding to the position of the component.
|
public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The easeInOut()
method combines the motion
of the easeIn()
and easeOut()
methods
to start the motion from zero velocity, accelerate motion,
then decelerate back to zero velocity.
Parameters
| t:Number — Specifies time.
|
|
| b:Number — Specifies the initial position of a component.
|
|
| c:Number — Specifies the total change in position of the component.
|
|
| d:Number — Specifies the duration of the effect, in milliseconds.
|
Returns | Number — Number corresponding to the position of the component.
|
public static function easeNone(t:Number, b:Number, c:Number, d:Number):Number
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The easeNone()
method defines a constant motion,
with no acceleration.
Parameters
| t:Number — Specifies time.
|
|
| b:Number — Specifies the initial position of a component.
|
|
| c:Number — Specifies the total change in position of the component.
|
|
| d:Number — Specifies the duration of the effect, in milliseconds.
|
Returns | Number — Number corresponding to the position of the component.
|
public static function easeOut(t:Number, b:Number, c:Number, d:Number):Number
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The easeOut()
method starts motion fast,
and then decelerates motion to a zero velocity as it executes.
Parameters
| t:Number — Specifies time.
|
|
| b:Number — Specifies the initial position of a component.
|
|
| c:Number — Specifies the total change in position of the component.
|
|
| d:Number — Specifies the duration of the effect, in milliseconds.
|
Returns | Number — Number corresponding to the position of the component.
