convert masked movieclip into bitmap and save it on server

Question

i have a dsgnArea----> a movieclip

dsgnArea is masked by dsgnAreaMask, which inturn is a movieclip

dsgnArea.mask=dsgnAreaMask;

the width,height and position of dsgnAreaMask and dsgnArea are same.

i dynamically added multiple movieclips and labels to dsgnArea; like.. dsgnArea.addChild(movieClip1); dsgnArea.addChild(movieClip2); dsgnArea.addChild(label1); dsgnArea.addChild(label2); and so on...

       these movieclips (movieClip1,movieClip2,......) and labels(label1,label2,....) positions can be altered in runtime..

but as i masked the dsgnArea with dsgnAreaMask, only a portion of the added movieClips and labels are visible...

So, my problem is to grab that visible portion in dsgnArea into a bitmap,like a screenshot of that particular dsgnArea, and save it in my server.

please help me out in this problem.

Say s is the DisplayObject object you want to capture and m is the mask applied on it.

var maskRect:Rectangle = m.getRect(s);
var matrix:Matrix = new Matrix(1, 0, 0, 1, -maskRect.x, -maskRect.y);

var w:Number = Math.min(s.width, maskRect.right) - maskRect.x;
var h:Number = Math.min(s.height, maskRect.bottom) - maskRect.y;

var bd:BitmapData = new BitmapData(w, h);
bd.draw(s, matrix);

Does that work?

The BitmapData draw method is what you are looking for. You can use it's clipRect param to define what you would like to draw (the masked parts).

Quasimondo did a handy little method to do this (take a snapshot of the whole displayObject), it's available here: http://www.quasimondo.com/archives/000670.php

I don't know if it works with masked content though. if it doesn't, the trick would be to translate the whole content by the size of the mask

var bounds:Rectangle = dsgnAreaMask.getBounds( dsgnAreaMask );

instead of using the content of the clip

var bounds:Rectangle = clip.getBounds( clip );
