[Gimp-developer] EXIF in JPEGs and TIFFs

[Jason Van Patten <jvp@xxxxxxxxxxxx>]

I'm sure this has been asked 5 bzillion times, so make this 5 bzillion and 
one. :-)  Is there a plan to support reading/writing EXIF information found in 
files such as JPEGs and TIFFs?  I've followed older threads that lead me to 
Lutz's libexif, which I'm up-to-date on.  But, without applying a very hairy 
patch to 1.3.x, I can't get GIMP to work with it.

And, libexif is JPEG-centric.  It's certainly handy, but it'd be even moreso 
to support other file formats (TIFF specifically.)  Daniel Stephens has 
written a C++ based CLI app called metacam 
http://www.cheeseplant.org/~daniel/pages/metacam.html which actually can read 
JPEGs and TIFFs.  Is that something someone could work with and develop into a 
plugin?  I've contacted Daniel and asked him a similar question; he said 
anyone can take what they want from his code but he hasn't a lot of time to 
donate to development.
