Alpha Channel?

[Marty Knapp]

I have an Apple Keynote presentation that I'm thinking of recreating in
Revolution so that I can customize the slide-to-slide timing and do a few
other things that keynote can't do. Can Revolution recognize a graphic image
that has an alpha mask-- to make part of an image transparent? If so, then I
could mimic the cutouts in Keynote.

Also, when you place a graphic image in Revolution is there a way to
constrain the proportions as you size the image?

Thanks,
Marty
