Dear Bob,

> I would be very grateful if somebody could shed some light onto this issue.

Are you able to supply 'tiffinfo' output for all of the input files and the output file?

It may be that the JPEG has been re-encoded.

at first, thank you very much for caring about the problem, and please excuse that your message has been rejected by our server. We are currently investigating why this has happened although we have whitelisted lists.osgeo.org (it seems that the list mail server, when connecting, does not give us an ENVFROM of xxx@lists.osgeo.org as expected, but instead an ENVFROM of <your email address>, which makes us scratch our heads ...). Fortunately, we have got the list digest in the meantime; otherwise, we would have missed your answer.

Anyhow, coming back to the subject:

I didn't want to clutter the actual message too much, so I have attached the results of tiffinfo. 1.txt contains the output of tiffinfo 1.tif, 2.txt contains the output of tiffinfo 2.tif, and so on. out.txt contains the results of tiffinfo out.tif.

Thank you very much again,

Binarus
