Flash AS3 BitmapData.draw() affects text formating

Question

Hi!

I need to display antialiased systemfonts (because the swf filesize must be small, therefore i can't embedd fonts). So I wrote this script in order to manually antialias the text

Code:

 public function renderTextField():BitmapData{
  var w:int = this["mainTextField"].textWidth+10;
  var h:int = this["mainTextField"].textHeight+10;
  var bitmapData:BitmapData = new BitmapData(w*3,h*3,false,0x000000);
  var antialiased:BitmapData = new BitmapData(w,h,false,0x000000);
  var transf:Matrix = new Matrix();
  transf.scale(3,3);
  bitmapData.draw(this["mainTextField"],transf);
  var bitmap:Bitmap = new Bitmap(bitmapData,"auto",true);
  transf = new Matrix();
  transf.scale(1.0/3.0,1.0/3.0);
  antialiased.draw(bitmap,transf,null,null,null,true);
  return antialiased;
 }

this works pretty well, but there's a nasty thing. Sometimes the scaling of the draw call affects the texts formatting. for example, the last word of a line will be the first word of the next line instead. This must not happen! does anyone have an idea why it happens and how i can avoid it? i want the text to be rendered into the bitmapData exactly as it appears in the textbox

thanks!

Take a look at the new text engine (requires Player 10.0, out for more than one year): http://labs.adobe.com/technologies/textlayout/
