[Gimp-user] Button halo help needed

[Mike Campbell]

I'm trying to create a button halo as shown in the image at http://www.freewebs.com/knievel/tipstricks.htm but not having much luck. I have been playing with bordered selections and stroking a selection but can't quite get the same effect as show here. Can anyone give me a hand on how to do this?

I can create the rounded rectangle and fill it with black and then reduce the transparency to 50%. So far so good. The problem is the halo affect. Please help me out.

Thanks,
Mike
