[sane-devel] sane-coolscan2.
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
[sane-devel] "sheet feed" typo in SANE SPEC?

What my paper form as > well as online dictionary know is "sheetfeed" or more precisely "sheet > feed". The scanner is fed sheets by the sheet feeder, hence a sheet fed scanner.

IMHO, these changes should not be committed although I don't mind if a space or hyphen is put between sheet and fed. FYI, aspell with a UK English dictionary suggests these as alternatives (1) and (2), resp. # (0) is sheeted, which is just plain wrong in this case.

I need it? :P But do you know another tool for removing dust and scratches?

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 need it? :P But do you know another tool for removing > dust and scratches? ICE is a combination of an IR channel being supplied by the scanner and some filtering code that makes use of it. The latter isn't implemented in SANE yet. > But it would be nice to have it supported in hardware. ICE is not a pure hardware feature, there's nothing we can do about that. Andras
