I'm trying to figure out how to export a PNG in applescript with the "use 256-color palette" option?
export newDoc to file ((exportLocation as text) & theFilename & ".png") as PNG
Thanks!

Why not use GIF instead as it has a 256 color limit built in? Just asking.

I could be wrong, but I don't think GIF supports transparency the same way as PNG. in GIF a pixels is either transparent or not, so anti-aliasing curves and edging don't look very nice on GIF compared to PNG. Mostly I just need PNG because that's the output customers want.
