I've received a request for information on an unknown tag. I often do, and most of the time that is useles, and a major nuisance on my part, since any information we have is published, and tags that are not documented are not documented because we don't have information on them.
But this time, the person who asked for information did have some info of his own. And by coïncidence, I found an old PDF-ed fax with a sortoff small specification soon after. So, it seems worthwhile to persue this and try to at least validate the little information I have.
The file 'format' is called 'GEL', and owned by a company called 'Molecular Dynamics'. Whatever the name of the format, it's just TIFF, and 10 registered private tags. The name of the company is equally useless, I can't seem to even find their website.
The PDF-ed fax document I found is called 'Molecular Dynamics GEL Image File Format Revision 2', dated March 2001. It goes about explaining that it's TIFF (taking the huge detour of specifying that the tags ImageWidth and so on and so on need to be in there), and next includes a few lines on each of the tags in the range from 33445 up to and including 33452.
Does anyone have any background information on this? Anyone knows what happened to 'Molecular Dynamics' and/or where to find them on the web? A newer version of the specification? TestImages that allow me to verify my understanding of these tags? Any additional info?
I don't wish to breach any copyrights, nor do I want to include just any unverified info in the tag directory, nor do I want to publish information without consulting with the private tag owner first and at least linking to the owning company. Thus, any and all information is greatly appreciated, and may lead to additional useful tag info in your tag directory http://www.awaresystems.be/imaging/tiff/tifftags.html.
