## Class ScaleTransition

- java.lang.Object
- - javafx.animation.Animation
  - - javafx.animation.Transition
    - - javafx.animation.ScaleTransition

-     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.*;

       ...

           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();

       ...

          public final ObjectProperty<Node> nodeProperty

      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.

      Default value:
        `Double.NaN`

    - #### interpolate

          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.
      Specified by:
        `interpolate` in class `Transition`
      Parameters:
        `frac` - The relative position
