Creating and applying filters

Filters allow you to apply a range of effects to bitmap and display objects, ranging from drop shadows to bevels and blurs. Each filter is defined as a class, so applying filters involves creating instances of filter objects, which is no different from constructing any other object. Once you’ve created an instance of a filter object, it can easily be applied to a display object by using the object’s filters property, or in the case of a BitmapData object, by using the applyFilter() method.
