Create pixel bender class for flex application

I am trying to integrate some pixel bender effects with an application that I created. I have the following code that is giving me problems. public function blackwhite() { //Pass the loaded filter to the Shader as a ByteArray var shader:Shader = new Shader(new TestFilter() as ByteArray); [login to view URL] = [100]; var filter:ShaderFilter = new ShaderFilter(shader); var im = [login to view URL]; //add the filter to the image [login to view URL] = [filter]; } Just need someone to integrate the effect. PM me for me info. Pretty simple
