AIR Android fullscreen masked background -- plz help

Question

Hi,I got the follow basic code making my backgound reszie to the stage dimentions:public function main()      {     stage.scaleMode = StageScaleMode.NO_SCALE;     stage.align = StageAlign.TOP_LEFT;     sw = stage.stageWidth     sh = stage.stageHeight     setPosition();     stage.addEventListener(Event.RESIZE, resizeLayout);}private function setPosition():void     {     bg.width = stage.stageWidth;     bg.height = stage.stageHeight;     bg.x = 0     bg.y = 0}private function resizeLayout(e:Event):void     {     setPosition();}The problem is if the bg movieclip is a has a mask inside of it, the dimentions are not of the masked area but of the total size.Any ideas how i can get around that will be appriciated. Thx Pavel

the factor you have to multiply the dimensions your bg with depends on the stage/mask ratio.

the formula is basically this:

(x*bg.width/bg.width) = stage.width/mask.width;

you need x therefore:

x= stage.width/mask.width;

that changes your function to:

private function setPosition():void { bg.scaleX = stage.width/bg.mask.width; bg.scaleY= stage.height/bg.mask.height; bg.x = 0 bg.y = 0

// the regristtration point of your mask should be aligned with the regirstrationpoint of your bg otherwise you have to calculate relative nullpoint
