[Libexif-devel] [newbie] Write Exif Data to a jpg file

[Fabien P. <fp...@wa...>]

Hello,
I'm currently working on an application that needs to write Exif data 
(GPS) into a jpeg file.
Actually, I have a tiffRepresentation (the image data) and I want to add 
GPS info into this data, in order to save the whole in a jpg file.
I want to use libexif, but I can't understand the API, and the 
documentation is a bit poor... :)
I'm using libexif on Mac OS X, with a Cocoa (Objective-C) application, 
and libexif was compiled successfully yet.
Many thanks for any link or pointer you might give me ;)
