[pstricks] dbicons in beamer: scaling problem

[Olga Lyashevska]

Dear all,

I have included the following figure into a beamer presentation. However
it is too large and does not fit on the slide. I wonder if there is a way
to scale it (as in \includegraphics using scale option) instead of
redrawing it? Can we scale figure environment at all?

Thank you in advance,

Olga
