Description Stephen Warren 2005-04-13 04:54:24 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
When you run "jpegtran -rot 90 -copy all x.jpg > y.jpg", the EXIF information isnt' re-written to contain the correct "Image Data/Orientation" field as it should be.

EXIF-aware applications will display the image incorrectly if this field is not correctly modified to reflect the true encoded orientation.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Find a JPEG image that contains EXIF orientation data.
2. In nautilus, right click it, and view the EXIF data. Note the "Image Data/Orientation" field.
3. run "jpegtran -rot 90 -copy all x.jpg > y.jpg"
4. In nautilus, right click the new y.jpg file, view the EXIF data again, and not that the "Image Data/Orientation" field has not been updated.

Comment 1 Matthew Miller 2006-07-10 21:10:14 UTC
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!
