blurX (BlurFilter.blurX property) -- Version 8

The amount of horizontal blur. Valid values are from 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.

Example

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

import flash.filters.BlurFilter;
var mc:MovieClip = createBlurFilterRectangle("BlurFilterBlurX");
mc.onRelease = function() {
    var filter:BlurFilter = this.filters[0];
    filter.blurX = 200;
    this.filters = new Array(filter);
}

function createBlurFilterRectangle(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:BlurFilter = new BlurFilter(30, 30, 2);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    rect.filters = filterArray;
    return rect;
}
