It stores annotations in tag 32932. I believe the tool refers to them as annotations. This, rather than burning text onto the image, is probably what the original poster is refering to. I don't know of any non-Windows application that can view them, but I haven't looked that hard. There is some information about this at this URL which I found, believe it or not, by doing a google search on 32932. http://www.awaresystems.be/imaging/tiff/tifftags/wangannotation.html There's a link from there to a spec for these annotations: http://www.kofile.com/support%20pro/faqs/annospec.htm I've never used this myself, but I've often received tiff files annotated in this way by Windows people who put annotations in with Windows Imaging and then thought the rest of the world would be able to see them. :-/ -- Jay Berkenbilt <ejb@ql.org> http://www.ql.org/q/
