Is there any reason why getColorBoundsRect() of the BitmapData Class would work in Flash player 10 but not in 9?
letterText.text ="H";
var textBitmapData:BitmapData = new BitmapData(letterText.width, letterText.height, true, 0x00000000);
textBitmapData.draw(letterText);
var bounds:Rectangle = textBitmapData.getColorBoundsRect(0xFF000000, 0x00000000, false);
trace(bounds); // (x=0, y=0, w=0, h=0) in Flash Player 9
trace(bounds); // (x=7, y=5, w=88, h=91) in Flash Player 10
