Actually, Gzip is really the same FlateEncode that
PDF accepts too. So, maybe you could skip
the use of LZW.

I'm sure that PDF understand JPEG compression too.

There is another compression that Revolution
supports that could be used in pdf files.
Maybe is base64 encode, but I'm not completely sure.
