In the as yet unreleased version you should use make-bitmap to make the bitmap and probably everything will just work.
If you're stuck with the release, then you want to make the bitmap% with the 'png/mask probably and then when you call draw-bitmap you have to supply the mask bitmap as an explicit argument. hth, Robby On Fri, Nov 19, 2010 at 11:44 PM, 김태윤 <kty1...@gmail.com> wrote: > hello > I am trying to overlay two or more images(not in universe) > but I can't make it as transparent > setting brush with transparent option doesn't work > original image's format is png though. > do I have to convert them into bitmap? > or is there any option or something to make it transparent? > thanks in advanced > > _________________________________________________ > For list-related administrative tasks: > http://lists.racket-lang.org/listinfo/users > _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
