The Zoom effect zooms the object in or out on a center point.
When you apply a Zoom effect to text rendered using a system font, Flex scales the text between whole point sizes. While you do not have to use embedded fonts when you apply a Zoom effect to text, the Zoom will appear smoother when you apply it to embedded fonts.
Note: The Zoom effect does not work when the Container.autoLayout property is false.
The <mx:Zoom> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:
Code Samples:
<mx:Zoom id="ID" captureRollEvents="false|true"
originX="Calculated" originY="Calculated" zoomWidthFrom="0.01"
zoomWidthTo="1.0" zoomHeightFrom="0.01" zoomHeightTo="1.0" />
