spark.effects.AnimateFilter

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.

The <mx:Blur> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:Blur
    id="ID"
    blurXFrom="val"
    blurXTo="val"
    blurYFrom="val"
    blurYTo="val"
  />
