ZIP seems about the best unpatented lossless method out there, so it's probably what would have been adopted.

How about PNGs algorithm? I'm not suggesting the interleaving stuff; but I thought the spatial filtering bits were important in order to get the best out of the subsequent ZIP style compression.

I'm fed up with not having a decent free lossless compression algorithm available for TIFF, too. Is there some way this group can move things along?

Cheers,
