Flex 4.0 sürümünden itibaren, Adobe bu sınıfa alternatif olarak spark.effects.Scale sınıfını kullanmanızı önerir.

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.

If true, prevents Flex from dispatching the rollOut and rollOver events if the mouse has not moved. Set this property to true when you use the Zoom effect to toggle the effect target between a big and small size.

For example, you use the rollOverEffect to trigger the Zoom effect to reduce the size of the target. As the target shrinks, the mouse pointer is no longer over the target, triggering a rollOut event, and the corresponding rollOutEffect. By setting the captureRollEvents property to true, you prevent Flex from dispatching the rollOut event unless it occurs because you moved the mouse.

Varsayılan değer şudur false.
