介绍 (Introduction)

Scale3D类围绕变换中心以三维方式缩放目标对象。标度为2.0表示对象放大2倍，标度为0.5表示对象缩小2倍。

Class 声明 (Class Declaration)

以下是spark.effects.Scale3D类的声明 -

public class Scale3D
   extends AnimateTransform3D

公共属性 (Public Properties)

S.No	财产和描述
1	scaleXBy : Number 在x方向上缩放对象的因子。
2	scaleXFrom : Number x方向的起始比例因子。
3	scaleXTo : Number x方向的结束比例因子。
4	scaleYBy : Number 在y方向上缩放对象的因子。
5	scaleYFrom : Number y方向的起始比例因子。
6	scaleYTo : Number y方向的结束比例因子。
7	scaleZBy : Number 在z方向上缩放对象的因子。
8	scaleZFrom : Number z方向的起始比例因子。
9	scaleZTo : Number z方向的结束比例因子。

公共方法 (Public Methods)

S.No	方法和描述
1	Scale3D(target:Object = null) 构造函数。

方法继承 (Methods Inherited)

该类继承以下类中的方法 -

spark.effects.AnimateTransform3D
spark.effects.AnimateTransform
spark.effects.Animate
mx.effects.Effect
flash.events.EventDispatcher

Flex Scale3D效果示例

让我们按照以下步骤通过创建测试应用程序来检查Flex应用程序中Scale3D Effect的使用情况 -

步	描述
1	在cn.xnip.client包下创建一个名为HelloWorld的项目，如Flex - Create Application一章中所述。
2	修改HelloWorld.mxml ，如下所述。保持其余文件不变。
3	编译并运行应用程序以确保业务逻辑按照要求运行。

以下是修改后的mxml文件src/cn.xnip/HelloWorld.mxml 。

<?xml version = "1.0" encoding = "utf-8"?>

   <fx:Script>
      <![CDATA[

            scaleEffect.play();
         }

   <fx:Declarations>
      <s:Scale3D id = "scaleEffect" target = "{imageFlex}"

        scaleZFrom = "1.0" scaleZTo = "{Number(scalingZ.text)}"
      />

            </s:layout>

                  <s:TextInput id = "scalingX" text = "1.4" width = "50" />
               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Scale By Y:" width = "70" />
                  <s:TextInput id = "scalingY" text = "1.4" width = "50" />
               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Scale By Z:" width = "70" />
                  <s:TextInput id = "scalingZ" text = "1.4" width = "50" />
               </s:HGroup>
               <s:Button label = "Apply Properties" click = "applyScaleProperties()" />
            </s:VGroup>
            <s:Image id = "imageFlex"
               source = "https://www.xnip.cn/images/flex-mini.png" />
         </s:Panel>
      </s:VGroup>
   </s:BorderContainer>
</s:Application>

一旦准备好完成所有更改，让我们像在Flex - Create Application章节中那样在正常模式下编译和运行应用程序。
