J> IMO, what Bob said makes a lot more sense. If you don't need

tiles, use strips. Saving large images (say over 4 kilopixels wide and high), you need tiles. I should add that for certain color spaces and compression modes, like black and white G3 or G4 compressed, it is customary to save a single strip even if the image is somewhat bigger then 4 kilopixels.

Agreed. I misinterpreted the original question as asking when to bother with fragmentation at all (strips OR tiles).

J> B> When saving data in general, IMO, you should try to preserve as much

of the original "framing" as possible. In other words, preserve byte-ordering, stripping, compression format, IFD layout, whatever offsets you can, and even any custom tags that your software may not understand or care about.

That is bad advice. Don't ever blindly preserve. You may be preserving data that is no longer valid after your operations.

OTOH, you may be losing data that are still valid (and meaningful) after your operations, and what's lost is gone. But the spec /does/ agree with your POV. :-)
