Nothing wrong with the image after running convert *except* the orientation
info is discarded.
I just realized -auto-orient has no effect and suspect this is part
of the same problem. I'd debug this further but my first attempt to
add printf statements failed.
I just realized the code I was changing landed in libwand.so and
not the convert binary. Installed the new .so and got:
grundler 548convert -auto-orient -quality 88 -resize 1600x1200 IMG_0001.JPG
xxx.jpg
Orientation: 0
Resize to: 1600x1200
grundler 549
I dump the Orientation when -auto-orient is evaluated in wand/mogrify.c.
It's obviously wrong (jhead reports 6, which I'm sure is correct).
Whatever is parsing/reading in the EXIF header is broken.
I can test patches if someone points me at the right code.
You should therefore go the upstream forward see
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3t=12998
and ask for help.
Upstream is quite reactive.
Thanks
