Example
The following example instantiates a new GlowFilter instance and applies it to a flat,
rectangular shape.
import flash.filters.GlowFilter;
var rect:MovieClip = createRectangle(100, 100, 0x003366,
"gradientGlowFilterExample");
var color:Number = 0x33CCFF;
var alpha:Number = .8;
var blurX:Number = 35;
var blurY:Number = 35;
var strength:Number = 2;
var quality:Number = 3;
var inner:Boolean = false;
var knockout:Boolean = false;
var filter:GlowFilter = new GlowFilter(color,
alpha,
blurX,
blurY,
strength,
quality,
inner,
knockout);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;
function createRectangle(w:Number, h:Number, bgColor:Number,
name:String):MovieClip {
var mc:MovieClip = this.createEmptyMovieClip(name,
this.getNextHighestDepth());
mc.beginFill(bgColor);
mc.lineTo(w, 0);
mc.lineTo(w, h);
mc.lineTo(0, h);
mc.lineTo(0, 0);
mc._x = 20;
