TIFF files display as an upside-down mirror image. The reproduction steps are:

  1. Scan a text document on a Konica Minolta bizhub C360i MFD & save to USB
  2. $ pdfimages -all $scanned_pdf innards
  3. $ fax2tiff $(<innards-000.params) -o document.tiff innards-000.ccitt
  4. $ geeqie document.tiff; #notice the upside-down mirror image
  5. $ display document.tiff; #notice ImageMagick displays the image properly
  6. $ gimp document.tiff; #notice Gimp also displays the image properly

There are no upstream bug reports covering this. One Debian bug report
is possibly related:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=646982

Bug 646982 reports a problem with correcting the orientation, but we
have to ask why the TIFF orientation needed correction in the first
place. This entry in the release notes looks interesting:

===8<------------------------------

Might that removed patch (0001-…) be related?  Because of that
possibility, I did not mark this bug as upstream.

Unfortunately I have no sample to attach. Perhaps I can scan an
arbitrary non-personal document in the future to supply a sample, if
needed.

Thanks for your report -
were applied to geeqie upstream at this time.

Upstream commit applying the content of the patch here:
https://github.com/BestImageViewer/geeqie/commit/fdb45ac5f99283775d655fa36b23b4be7905951e

A sample would be helpful - I have tried saving an tiff image in
gimp and shown it in geeqie, but that showed without error.

I would very much suppose that the behaviour in this case is the same
in the upstream source as in the Debian package.

Can you please provide an example that presents the problem?
