In my search for the almighty solution to dynamic anti-aliased text being displayed through a mask I discovered a bug. Not sure if its native to Flash 8 or across the board.
Dynamic text does not respond to the complete shape of a mask set with actionscript, it only responds to the bounding box.
Check out this example: http://www.triggermotion.com/flash/mask_bug.html
All of the sites I build have a ton of xml driven text content that typically resides behind a mask. The masking is fine if the text is aliased, though I prefer to use anti-aliases text as I find it easier on the eyes.
If you’ve got a solution I’ve missed, I’ll buy you a beer.
