Runtime Versions: | Flash Player 9, AIR 1.1 |
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.

addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | ||
Captures the current values of the relevant properties
on the effect's targets and saves them as end values. | Effect | ||
Captures the current values of the relevant properties
of an additional set of targets
Flex uses this function when a data change
effect is run.
| Effect | ||
Captures the current values of the relevant properties
on the effect's targets. | Effect | ||
Creates a single effect instance and initializes it. | Effect | ||
Takes an Array of target objects and invokes the
createInstance() method on each target. | Effect | ||
Removes event listeners from an instance
and removes it from the list of instances. | Effect | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Interrupts an effect that is currently playing,
and jumps immediately to the end of the effect. | Effect | ||
Returns an Array of Strings, where each String is the name
of a property changed by this effect. | Effect | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Pauses the effect until you call the resume() method. | Effect | ||
Begins playing the effect. | Effect | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Resumes the effect after it has been paused
by a call to the pause() method. | Effect | ||
Plays the effect in reverse, if the effect is currently playing,
starting from the current position of the effect. | Effect | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Stops the effect, leaving the effect targets in their current state. | Effect | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of
