```
public final class ScaleTransition
extends Transition
```
This Transition creates a scale animation that spans its duration. This is done by updating the scaleX, scaleY and scaleZ variables of the node at regular interval.
It starts from the (fromX, fromY, fromZ) value if provided else uses the node's (scaleX, scaleY, scaleZ) value.
It stops at the (toX, toY, toZ) value if provided else it will use start value plus (byX, byY, byZ) value.
The (toX, toY, toZ) value takes precedence if both ( toX, toY, toZ) and (byX, byY, byZ) values are specified.
Code Segment Example:
```
 
 import javafx.scene.shape.*;
 import javafx.animation.transition.*;

 ...

     Rectangle rect = new Rectangle (100, 40, 100, 100);
     rect.setArcHeight(50);
     rect.setArcWidth(50);
     rect.setFill(Color.VIOLET);

     ScaleTransition st = new ScaleTransition(Duration.millis(2000), rect);
     st.setByX(1.5f);
     st.setByY(1.5f);
     st.setCycleCount(4f);
     st.setAutoReverse(true);

     st.play();

 ...

    The target node of this ScaleTransition.
    It is not possible to change the target node of a running ScaleTransition. If the value of node is changed for a running ScaleTransition, the animation has to be stopped and started again to pick up the new value.

  - duration
```

    The duration of this ScaleTransition.
    It is not possible to change the duration of a running ScaleTransition. If the value of duration is changed for a running ScaleTransition, the animation has to be stopped and started again to pick up the new value.
    Note: While the unit of duration is a millisecond, the granularity depends on the underlying operating system and will in general be larger. For example animations on desktop systems usually run with a maximum of 60fps which gives a granularity of ~17 ms. Setting duration to value lower than Duration.ZERO will result in IllegalArgumentException.

```
public void interpolate(double frac)

    The method interpolate() has to be provided by implementations of Transition. While a Transition is running, this method is called in every frame. The parameter defines the current position with the animation. At the start, the fraction will be 0.0 and at the end it will be 1.0. How the parameter increases, depends on the interpolator, e.g. if the interpolator is Interpolator.LINEAR, the fraction will increase linear. This method must not be called by the user directly.
