I'm the main developper of digiKam, an open-source GUI applications to manage photograph under linux (http://www.digikam.org)
In digiKam, we have a pictures editor and an interface to extract Exif/Iptc metadata from RAW, JPEG, PNG, and TIFF files format (16 bits color depth supported).
I'm currently trying to finalize a TIFF codec to write a tiff file with metadata support. All work fine excepted the EXIF tags using libtiff 3.8.2.
My current TIFF codec source code is here:
I'm sure that my implementation about Exif tags recording is wrong in TIFFLoader::save() method. Duing a big difficulty to found substancial informations (source code examples in fact) about Exif tags support and libtiff, I'm trying this mailing (:=)))...
Please, let's me hear what is wrong in my implementation. Thanks in advance for your help and your comments.
