Capturing bitmapData while in FullScreen

Question

Is this possible?? Limitation with the Flash player?
I am trying to do an image capture while in full screen, however the full image area is only partially captured, or the coordinates are off (see images below). The document size is 100x700, and the stage is set not to scale / aligned to bottom.
I've been able to capture the right size, however it always seems to capturing the image from the wrong start x,y position. There is some elements out of bounds but I am just trying to clip them depending on the current stage width and height.
In the source files you will see a few of my attempts commented off (below/attached). Is anyone willing to help me troubleshoot this.

Here's the code for the php ("screenshot_download.php") :
<?php
if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {
    // get bytearray
    $im = $GLOBALS["HTTP_RAW_POST_DATA"];
    // add headers for download dialog-box
    header('Content-Type: image/jpeg');
    header("Content-Disposition: attachment; filename=".$_GET['name']);
    echo $im;
}  else echo 'An error occured.';
?>

Thanks all. I was able to resolve this issue :
Here it is in action (right click for fullscreen option) :

I decided to break from this while I worked on making other updates to the site. And yesterday I took another look at it, and took me about 15mins to relize what I was doing wrong. Turns out I had it in one of my attemps but my calculations was backwords.
    var jpgSource:BitmapData = new BitmapData (stage.stageWidth, stage.stageHeight);
    var trans:Matrix = new Matrix();
    trans.translate(centerpointW-500, stage.stageHeight-700);
     //  I had this as 500-centerpointW, 700-stage.stageHeight
    jpgSource.draw(m, trans, null,null,null,true);
    var jpgEncoder:JPGEncoder = new JPGEncoder(85);
    var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);
    var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");
     var jpgURLRequest:URLRequest = new URLRequest("screenshot_download.php?name=sketch_"+fileName);
    jpgURLRequest.requestHeaders.push(header);
    jpgURLRequest.method = URLRequestMethod.POST;
    jpgURLRequest.data = jpgStream;
     navigateToURL(jpgURLRequest, "_self");
Thanks again, I attached the updated FLA if it can help anyone else.
