Tiling dynamically loaded bitmaps

programming flash
1

I read the tutorial on how to tile bitmaps in Flash 8 (http://www.kirupa.com/developer/flash8/tiledbackground_flash8.htm) and its perfect. I actually had to tile an external bitmap, and that tutorial pared with http://www.adobe.com/devnet/flash/articles/image_api_05.html did the trick (I’ll add the code at the end for anyone else with this problem).

My question is this. Will a tiled graphic like this cause any extra slow down when playing (and animated)? I was originally going to make a grid of empty movie clips and fill them each with one copy of the bitmap, which I thought definitely would cause some level of slowdown.

import flash.display.BitmapData
this.createEmptyMovieClip("holder_mc",this.getNextHighestDepth());
loader = new MovieClipLoader()
loader.addListener(this)
loader.loadClip("image.png",holder_mc)

function onLoadInit(){
    myBitmap = new BitmapData(holder_mc._width, holder_mc._height);
    myBitmap.draw(holder_mc);
	
	this.beginBitmapFill(myBitmap);
	this.lineTo(Stage.width, 0);//change these lines to change the size of the fill
	this.lineTo(Stage.width, Stage.height);
	this.lineTo(0, Stage.height);
	this.lineTo(0, 0);
	this.endFill();
    holder_mc.removeMovieClip()
}
