求用flex实现图片缩放拉伸和旋转功能

求用flex实现图片缩放拉伸和旋转功能，功能类似附件图片

Answer 1

放大缩小直接img1.with += 20;img1.height += 20;就可以
下面是旋转的代码：

<?xml version="1.0" encoding="utf-8"?>
<!-- Simple example to demonstrate the Rotate effect. -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
initialize="Font.registerFont(myriad_font);">

<mx:Script>
<![CDATA[

import flash.text.Font;

[Embed("assets/MyriadWebPro.ttf", fontName="MyMyriad")]
public var myriad_font:Class;

[Bindable]
public var angle:int=0;

private function rotateImage():void {
rotate.end();
angle += 45;
rotate.play();
}
]]>
</mx:Script>

<mx:Rotate id="rotate" angleFrom="{angle-45}" angleTo="{angle}" target="{myVB}"/>

<mx:Panel title="Rotate Effect Example" horizontalAlign="center"
width="75%" height="75%" layout="horizontal"
paddingTop="5" paddingLeft="10" paddingRight="10" paddingBottom="5">

<mx:VBox id="myVB" width="50%" horizontalAlign="center">
<mx:Label text="Nokia 9930"
fontFamily="MyMyriad" fontSize="14"/>

<mx:Image id="img"
source="@Embed(source='assets/Nokia_6630.png')"/>
</mx:VBox>

<mx:Text width="50%" color="blue"
text="Click the button to rotate the image 45 degrees. Use an embedded font when applying the Rotate effect to text."/>

<mx:ControlBar>
<mx:Button label="Rotate 45 Degrees" click="rotateImage();"/>
</mx:ControlBar>
</mx:Panel>
</mx:Application>
