// Load an image onto the Stage.
var loader:Loader = new Loader();
var url:URLRequest = new URLRequest("http://www.helpexamples.com/flash/
images/image1.jpg");
loader.load(url);
this.addChild(loader);
function applyFilter(event:MouseEvent):void
// Create the convolution matrix.
var matrix:Array = [ 0, 0, 0,
0, 0, 1,
0, 0, 0 ];
var convolution:ConvolutionFilter = new ConvolutionFilter();
convolution.matrixX = 3;
convolution.matrixY = 3;
convolution.matrix = matrix;
convolution.divisor = 1;
loader.filters = [convolution];
loader.addEventListener(MouseEvent.CLICK, applyFilter);
