I can second that - we do a lot of work for European aerospace companies and it is pretty much all (certainly all the b&w stuff) in either pdf + G4 or tiff + G4. At the end of the day, you can always store the entire G4 decompression scheme in a tag (OK, I know I am not worthy but wth!) and it will cost you a couple (OK maybe a few K) of hundred bytes per image. And that is if you are REALLY paranoid! Cheers Antoine -- This is where I should put some witty comment.
