BlurFilter

I was trying to blur the lines. But this is not working .... Please help
Just copy paste following code on first frame and test it. Else you can download here.

Code:



import flash.filters.BlurFilter;
var blurX:Number = 40;
var blurY:Number = 40;
var quality:Number = 5;
var filter:BlurFilter = new BlurFilter(blurX, blurY, quality);
var filterArray:Array = new Array();
filterArray.push(filter);
m.filters = filtersArr;
//=========================
myLines.filters = filterArray;
this.createEmptyMovieClip("myLines", this.getNextHighestDepth());
function drawLine() {
myLines.lineStyle(5, 0xff0000, 100);
//myLines.beginFill(0xff0000);
myLines.moveTo(ix, iy);
//myLines.lineTo(ix+6, iy+6);
//myLines.lineTo(ex+6, ey+6);
myLines.lineTo(ex, ey);
myLines.filters = filtersArr;
}
var ix, iy, ex, ey, keepDraw;
onMouseDown = function () {
ix = _xmouse;
iy = _ymouse;
keepDraw = setInterval(function () {
ex = _xmouse;
ey = _ymouse;
drawLine();
ix = ex;
iy = ey;
}, 10);
};
onMouseUp = function () {
clearInterval(keepDraw);
};
// Assign the filters array to the filters property
// of imageClip in order that the filters will
// get applied.
