blurY (DropShadowFilter.blurY property)
public blurY : Number
The amount of vertical blur. Valid values are 0 to 255 (floating point). The default value is 4.
Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly
than other values.
Availability: ActionScript 1.0; Flash Player 8

property on an existing movie clip when a user
clicks it.
import flash.filters.DropShadowFilter;
var mc:MovieClip = createDropShadowRectangle("DropShadowBlurY");
mc.onRelease = function() {
var filter:DropShadowFilter = this.filters[0];
filter.blurY = 40;
this.filters = new Array(filter);
}
function createDropShadowRectangle(name:String):MovieClip {
var art:MovieClip = this.createEmptyMovieClip(name,
this.getNextHighestDepth());
var w:Number = 100;
var h:Number = 100;
art.beginFill(0x003366);
art.lineTo(w, 0);
art.lineTo(w, h);
art.lineTo(0, h);
art.lineTo(0, 0);
art._x = 20;
art._y = 20;
var filter:DropShadowFilter = new DropShadowFilter(15, 45, 0x000000, .8,
16, 16, 1, 3, false, false, false);
var filterArray:Array = new Array();
filterArray.push(filter);
art.filters = filterArray;
