I don't know if BMP has a gamma. It is optional in the PNG. It might also have other related parameters that would be used instead.
I can look at a hex dump and see if the PNG has one, but somebody else might have a utility that allows looking at that or fiddling with it.
It might be that Revolution is ignoring the Gamma or handling it wrong. I suspect not, since there is a screenGamma and since a gamma is created when a PNG is created from an image object. It is worth looking into, though. It might be that the file has the more complicated screen parameters and Revolution does not handle those.
It might be that the PNG does not have a Gamma. I would have thought Photoshop would have saved it. I'll see what my Mac Photoshop, does.
