Flex - Scale3D Effect

Introduction

The Scale3D class scales a target object in three dimensions around the transform center. A scale of 2.0 means the object is magnified by a factor of 2, and a scale of 0.5 means the object is reduced by a factor of 2.

Class Declaration

Following is the declaration for spark.effects.Scale3D class −

public class Scale3D
   extends AnimateTransform3D

Flex Scale3D Effect Example

Let us follow the following steps to check usage of Scale3D Effect in a Flex application by creating a test application −

Once you are ready with all the changes done, let us compile and run the application in normal mode as we did in Flex - Create Application chapter. If everything is fine with your application, it will produce the following result: [ Try it online ]
