Flex 4：缩放到一点（放大鼠标单击的图像）
我一直在努力让它发挥作用，但我似乎无法弄清楚。有一个 Image 控件，当我单击它时，我需要放大（使用单击鼠标的中心/变换点）。
我的缩放过渡效果很好，但是当我设置 transformX & tranformY （autoCenterTransform false）它不会放大到该点。
这是我的代码，仅放大（不放大到特定点）
<fx:Script>
<![CDATA[
protected function imgLogo_clickHandler(event:MouseEvent):void
{
transformer.play();
}
]]>
</fx:Script>
<fx:Declarations>
<s:Parallel id="transformer" target="{imgLogo}">
<s:Scale scaleXBy="0.5" scaleYBy="0.5" />
</s:Parallel>
</fx:Declarations>
<mx:Image id="imgLogo" width="250" x="100" y="100"
maintainAspectRatio="true" source="@Embed('src/logo.png')"
click="imgLogo_clickHandler(event)" />
非常感谢任何帮助。 谢谢
I've been trying to get this working and I can't seem to figure it out. There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked).
I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point.
Here is my code that only zooms in (not to a specific point)
<fx:Script>
<![CDATA[
protected function imgLogo_clickHandler(event:MouseEvent):void
{
transformer.play();
}
]]>
</fx:Script>
<fx:Declarations>
<s:Parallel id="transformer" target="{imgLogo}">
<s:Scale scaleXBy="0.5" scaleYBy="0.5" />
</s:Parallel>
</fx:Declarations>
<mx:Image id="imgLogo" width="250" x="100" y="100"
maintainAspectRatio="true" source="@Embed('src/logo.png')"
click="imgLogo_clickHandler(event)" />
Any help is greatly appreciated.
Thanks

经过进一步挖掘，我能够弄清楚这一点。您需要将
MouseEvent中的transformX和transformY设置为舞台坐标（而不是本地坐标）。并像这样修改
Scale的声明After some further digging, I was able to figure this out. You need to set the
transformXandtransformYto the stage coordinates (NOT the local ones) from theMouseEvent.And modify the declaration for the
Scalelike so
