blurX (GlowFilter.blurX property) -- Version 8

The amount of horizontal blur. Valid values are 0 to 255 (floating point). The default value is 6. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

Example

The following example changes the blurX property on an existing movie clip when a user clicks it.

import flash.filters.GlowFilter;

var mc:MovieClip = createGlowFilterRectangle("GlowFilterBlurX");
mc.onRelease = function() {
    var filter:GlowFilter = this.filters[0];
    filter.blurX = 20;
    this.filters = new Array(filter);
}

function createGlowFilterRectangle(name:String):MovieClip {
    var rect:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth());
    var w:Number = 100;
    var h:Number = 100;
    rect.beginFill(0x003366);
    rect.lineTo(w, 0);
    rect.lineTo(w, h);
    rect.lineTo(0, h);
    rect.lineTo(0, 0);
    rect._x = 20;
    rect._y = 20;

    var filter:GlowFilter = new GlowFilter(0x000000, .8, 16, 16, 1, 3, false, false);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    rect.filters = filterArray;
    return rect;
}
