![]() | Starting with Flex 4.0, Adobe recommends that you use the spark.effects.AnimateFilter class as an alternative to this class. In Flex 4, use the AnimateFilter effect with a Blur bitmap filter. |
The Blur effect lets you apply a blur visual effect to a component. A Blur effect softens the details of an image. You can produce blurs that range from a softly unfocused look to a Gaussian blur, a hazy appearance like viewing an image through semi-opaque glass.
The Blur effect uses the Flash BlurFilter class as part of its implementation. For more information, see flash.filters.BlurFilter.
If you apply a Blur effect to a component, you cannot apply a BlurFilter or a second Blur effect to the component.
