Too bad you didn't ask, I've got a function in one of my site downloads: MakeAlphaFromRGB()
which does exactly that: msg box: go URL "http://www.altuit.com/webs/altuit2/RunRev/testComposite.rev"; Scott Rossi wrote:
In any event, I've been working a lot lately with image/alphaData and with Ken Ray's help figured out a little function that can create alphaData from a black and white image. This "getAlpha" function requires the long ID of a source image, and though it is slower than simply reading the alphaData of an existing transparent image (several seconds for a large image), it allows for the creation of masks where no transparency info is present.
