I see it is not that easy to copy the exif tag in one GetField/SetField-way, cause the tag is an IFD itself. Do anybody has a sample how to solve this problem with libtiff and write an EXIF_IFD embedded in my copied file?
The answer to this is changing...
The development ChangeLog for the forthcoming libtiff release claims that EXIF IFD tags are supported. I have not tried using this feature yet to see how well it works in practice.
