Warning: Filter will not render

[friendlygiraffe]

Hi,

I get this error in Flash player 9 (10 works fine)

The image I'm trying to distort is 2203 x 250, so I don't know why it's saying the maximum is 3334 ?

Warning: Filter will not render.  The DisplayObject's filtered dimensions (3334, 571) are too large to be drawn.

public function displaceImage(e:Event):void 
        {   
            
            var rt:MovieClip = Main(root);
            
            var speed:Number = 2;
            var imgWdth:Number = rt.image_mc.image1_mc.width;

            rt.displace_mc.visible = false;
            
            starting_position += mult;
            mult = +speed;
                
            displacementData.draw(rt.displace_mc);
            displacementFilter = new DisplacementMapFilter(displacementData,new Point(starting_position,0),1,1,displacementAmount,displacementAmount,DisplacementMapFilterMode.CLAMP,0,0);
            displacementFilter.scaleX = displacementFilter.scaleY = displacementAmount;
            rt.image_mc.filters = [displacementFilter];

            rt.image_mc.x -= speed;
            
            if(rt.image_mc.x < -imgWdth){
                trace('adasd '+rt.image_mc.image1_mc.name);
            }
            
            
        }
