gjpegtran
The gjpegtran program is a wrapper for the jhead and jpegtran command line utilities. These utilities allow you to do lossless transformations of jpeg images such as rotations without losing any image data or exif information. gjpegtran wraps them in a more usable graphical face that is integrated with the gnome mime infrastructure and nautilus file manager.
Distribution
gjpegtran is distributed under the GPL version 2 with the clause about using future versions of the GPL at the discretion of the recipient deleted.
Requirements
As implied by the description above, gjpegtran requires the jhead and jpegtran command line utilities. It also requires python, libglade, and the pygtk/pygnome bindings. If you have a recent Linux distribution, it is quite likely that you have most of these already. In particular, RedHat 7.2/7.3 have all of these requirements except jhead. Just in case your distribution does not, here are URLs for more information about all of the requirements:
- jhead: http://www.sentex.net/~mwandel/jhead/
- jpegtran (part of libjpeg): http://www.ijg.org/
- pyglade/pygtk/pygnome: http://www.daa.com.au/~james/gnome/
- python: http://www.python.org/
Since I use RedHat, the only dependency I am missing is jhead. I've posted source and binary RPMs for jhead below for the convenience of other RedHat users.

More information on installation and usage is included in the README file packaged with the distribution.
Packages
In general, these binary packages should remain true to the file system layout of the distribution on which they are compiled, and should run on them without other dependencies if the latest errata have been installed.| Distribution | Download File | Download Size |
|---|---|---|
| RedHat 7.x | gjpegtran-0.5-4.src.rpm | 17 KB |
| jhead-1.8-1.src.rpm | 38 KB | |
| RedHat 7.3 | gjpegtran-0.5-4.noarch.rpm | 16 KB |
| jhead-1.8-1.i386.rpm | 29 KB |
All my binary packages are signed so that you can verify they
came from me. Whether you actually trust me or not is something you
have to decide for yourself. To check the signatures, you will need
my gpg public key.
