I am still running GIMP1.2, so I have no experience writing plug-ins for GIMP2 and I cannot test it. Of course, if you'd port it, you'd save him some work :-) Just wondering: how many scanners are there (apart from the coolscan series) that support an infra-red channel? And how do the backends for those scanners handle this channel; how do you get it in the GIMP? As an alpha chanel (like the coolscan) or as an additional picture (like the coolscan2)? From previous discussions about the coolscan, I remember that the SANE-standard does not really cover this. -- (c) ljm ( xs4all)No part of this copyright message may be reproduced, read or seen, dead or alive or by any means, including but not limited to telepathy without the benevolence of the author.

You'll need some experimenting with enhancing the contrast in the infra-red image. Also, see http://andreas.rick.free.fr/sane/ for the original plugin. The plug-in part from my tar is practically an unchanged copy of this.

There's nothing else the scanner can output, and because of the way it's designed, it can't even sample greyscale. Any conversion to any other colour space must be done in software. As far as I'm aware, scanners never support CMYK, which is an anachronism anyway. Maybe scanner _drivers_ do, but that's another story. > > It isn't implemented yet.

I have a Nikon coolscan LS-40. I run it under FreeBSD and everything works fine but I cant choose grayscale or any colormode at all. Hm. What about ICE. Does it work with sane? --=20 MVH Peter Ankerst=E5l.

The scanner doesn't support anything but RGB(+I). I made the decision not to include code that converts from RGB to greyscale into the backend, this should really be done on the frontend side or in GIMP or similar. > Hm. What about ICE. Does it work with sane? It isn't implemented yet. The IR readout works, but the driver side of ICE is not yet available in SANE. It isn't simply a hardware feature that needs enabling. Andras
