I was reading the Duplicate Background tutorial ([http://www.kirupa.com/developer/mx2004/duplicatebackground.htm](http://www.kirupa.com/developer/mx2004/duplicatebackground.htm)) on how to make an image tile in the background of a SWF tile. I am trying to figure out how to position that tile so that it is centered instead of starting at the top left. I realize it must be in this part of the code:

bg.\_x = tile\_width_x;  
bg.\_y = tile\_height_y;

but i’m not real sure on how to make it actually work. Any help would be much appreciated.  
Thanks,
