quality (BlurFilter.quality property) -- Version 8

The number of times to perform the blur. Valid values are from 0-15. The default value is 1, which is equivalent to low quality. A value of 2 is medium quality. A value of 3 is high quality and approximates a Gaussian blur.

For most applications, a quality value of 1, 2, or 3 is sufficient. Although you can use additional numeric values up to 15 to increase the number of times the blur is applied, thus getting a more blurred effect, be aware that higher values are rendered more slowly. Instead of increasing the value of quality, you can often get a similar effect, and with faster rendering, by simply increasing the values of blurX and blurY.

Example

The following example creates a rectangle and applies a blur filter with a quality value of 1 to the rectangle. When you click the rectangle, the quality increases to 3, and the rectangle becomes more blurry.

import flash.filters.BlurFilter;
var mc:MovieClip = createBlurFilterRectangle("BlurFilterQuality");
mc.onRelease = function() {
    var filter:BlurFilter = this.filters[0];
    filter.quality = 3;
    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, 1);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    rect.filters = filterArray;
    return rect;
}
