Please check this affirmation about copyPixels

Dear all,

Please tell me if this affirmation is correct:

I have this code

var myMC:mcSet = new mcSet(832,576); // an image in the library
var titleBitmap:Bitmap = new Bitmap(myMC);

var _map:BitmapData = new BitmapData(1920,1440,false, 0xffffffff);// image holder

var _bitmap:BitmapData = new BitmapData(512,416,false, 0xffffffff); //part of _map I want to render
var image:Bitmap = new Bitmap(_bitmap);
image.x =xOffset;
image.y = yOffset;
this.addChild(image);

Now I populate _map

function fillMap (){
….
rect = new Rectangle(posX,posY,widthRect,heightRect);
position = new Point (newPosX,newPosY);
_map.copyPixels(titleBitmap.bitmapData,rect,position);
….
}

And now I populate _bitmap:

function fillBtimap (){
…
rect = new Rectangle(posX,posY,widthRect,heightRect);
positiont = new Point (newPosX,newPosY);
	_bitmap.copyPixels(_map,rect,position);
…
}

Ok, this is my assumption:

Because _map has already my image in memory, when I populate _bitmap using _map, I am not adding extra data to memory; I am just making reference to memory. Is this correct?

I will appreciate your feedback
