<br><div><br>Note : Coments, rating, etc are already writed in TIFF file when you save image from Editor... But of course this is not yet done in fly like with JPEG from Album view.<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
digikam uses exiv2 to access and write meta-data.<br>Support for tiff is being worked on (see <a href="http://www.exiv2.org/">http://www.exiv2.org/</a>),<br>but I don't know the current status.</blockquote><div><br>TIFF writing IO with Exiv2 will be the next job to do . Currently, XMP is the main task for next Exiv2 release
0.16 planed to December. TIFF writing mode is temporaly stopped.<br><br>Few developement have been already done but not yet finalized...<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
So to me it seems that for a proper solution to<br>the problem you discuss, it should be done on the level of exiv2.</blockquote><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Gilles, and Andreas will be able to give a more detailed account on this,<br>but I would suggest to get Andreas Huggel's from exiv2 opinion first,<br>before you start hacking ;-)</blockquote><div><br>Andreas is not in this room, only in digikam-devel ML. You can contact him directly at "ahuggel at gmx dot net" or using Exiv2 ML
