Recently I’ve had the need to scale a dynamic text field which was fed by XML. Readability after scaling was not important, but it did have to look good (it’s for a full Flash site). However, scaling the MovieClip that the text field was in would cause some pretty chaotic behavior with the text — the text would try to scale with its parent but in doing so would shift around spastically until the parent MC settled into a new scale. This was unacceptable.

A quick google didn’t yield anything relevant, so I was left to my own devices. I remembered being able to draw pixels to a BitmapData object while writing my game in order to improve performance, so I figured I’d see if I could just copy the pixels from the text field and “bake” it into a bitmap.
Turns out you can. In fact, Adobe had already done this in the help files and it’s actually extremely easy. Check it out:
var tf:TextField = new TextField();
tf.text = "bitmap text";
var myBitmapData:BitmapData = new BitmapData(80, 20);
myBitmapData.draw(tf);
var bmp:Bitmap = new Bitmap(myBitmapData);
this.addChild(bmp);
No sweat right? Anyway, since I didn’t find any help on this anywhere else (granted, I didn’t look very hard), I thought I’d share this little adventure of mine. Hope it’s helpful.
