Hello list! This is just a wild shot out there, and maybe I'm firing in a complete wrong direction. Anyway, I'd be grateful for any word of help on this problem.

I am running Ubuntu Linux and its update system recently updated my libtiff libraries, to a current version of 3.7.3. I have now discovered that the ImageMagick command line tool convert, cannot convert jpeg to tiff anylonger. This used to work just fine, and I am assuming the update that I vaguely recall is the cause of the problem. I do unfortunately not know what version of libtiff I had before the update, though I suppose one could find out about that with some investigation.

It sounds like the new libtiff is not entirely compatible with the old libtiff. It may still work if JPEG compression is not used. Try

   convert file.jpg -compress none file.tiff

and see if that works.
