Example
The following example changes the angle property on an existing movie clip when a user
clicks it.
import flash.filters.GradientGlowFilter;
var mc:MovieClip = createGradientGlowRectangle("GlowAngle");
mc.onRelease = function() {
var filter:GradientGlowFilter = this.filters[0];
filter.distance = 50;
filter.angle = 90;
this.filters = new Array(filter);
}
function createGradientGlowRectangle(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 colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF];
var alphas:Array = [0, 1, 1, 1];
var ratios:Array = [0, 63, 126, 255];
var filter:GradientGlowFilter = new GradientGlowFilter(0, 45, colors,
alphas, ratios, 55, 55, 2.5, 2, "outer", false);
var filterArray:Array = new Array();
filterArray.push(filter);
art.filters = filterArray;
return art;
blurX (GradientGlowFilter.blurX property)
public blurX : Number
The amount of horizontal blur. Valid values are 0 to 255. A blur of 1 or less means that the
original image is copied as is. 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.
