Panning image not works properly

Question

Hello all,
I am developing a movie which panning an image. Following code works fine but it leaves blank area when i run it (when i switch to full screen at browser).
function panThisImage(target:MovieClip, speed:Number,speed1:Number, dir:int) {
var mousePercent:Number = mouseX / stage.stageWidth;
var mousePercent1:Number = mouseY / stage.stageHeight;
stage.addEventListener(MouseEvent.MOUSE_MOVE, panImage);
target.cacheAsBitmap = true;
function panImage(E:MouseEvent):void {
var mSpeed:Number;
var mSpeed1:Number;
mousePercent = mouseX / stage.stageWidth;
mousePercent1 = mouseY / stage.stageHeight;
if (dir == 1) {
mSpeed =1-mousePercent;
} else {
mSpeed =mousePercent;
if (dir==1) {
mSpeed1 =1-mousePercent1;
} else {
mSpeed1=mousePercent1;
target.destX = Math.round(-((target.width-stage.stageWidth) * mSpeed));
target.destY = Math.round(-((target.height-stage.stageHeight) * mSpeed1));
if (target.hasEventListener(Event.ENTER_FRAME)) {
target.removeEventListener(Event.ENTER_FRAME, del);
target.addEventListener(Event.ENTER_FRAME, del);
function del(E:Event):void {
if (Math.abs(target.x-target.destX) <= 1) {
target.x = Math.round(target.destX);
target.removeEventListener(Event.ENTER_FRAME, arguments.callee);
} else {
target.x += (target.destX-target.x) * (speed / 100);
if (Math.abs(target.y-target.destY) <= 1) {
target.y = Math.round(target.destY);
target.removeEventListener(Event.ENTER_FRAME, arguments.callee);
} else {
target.y += (target.destY-target.y) * (speed1 / 100);
panThisImage(imgLoader,1,1,2);

Answer 1

i mean, it will start from (0,0) coordinates and will not show any blank area. (but i do not want strecth mode)
