.TH sane\-coolscan 5 "13 Jul 2008" "@PACKAGEVERSION@" "SANE Scanner Access Now Easy"
.IX sane\-coolscan
.SH NAME
sane\-coolscan \- SANE backend for Nikon film-scanners
.SH ABOUT THIS FILE
This file is a short description of the coolscan backend for
.BR SANE .
.SH DESCRIPTION
The
.B sane\-coolscan
library implements a SANE backend that provides the interface to the following Nikon
Coolscan Film scanners: Nikon LS20, LS30, LS1000, LS2000.
.B Even though the backend has worked for a number of people, there are still some
problems, especially in combination with some SCSI card/drivers (AHA-1505/aha152x.o)
and the autofocus command.
You should consider this backend 'alpha' and be careful when using it the first time.
.SH CONFIGURATION
The configuration file for this backend resides in
.IR @CONFIGDIR@/coolscan.conf .
Its content is a list of device names that correspond to Nikon Coolscan scanners. Empty lines
and lines starting with a hash mark (#) are ignored. A sample configuration file is
shown below:
.nf
#scsi Vendor Model Type
scsi Nikon * Scanner
/dev/scanner
.fi
The special device name must be a generic SCSI device or a symlink to such a device.
To find out to which device your scanner is assigned and how you can set the
permissions of that device, have a look at
.BR sane\-scsi (5).
.SH SCSI ADAPTER TIPS
Some SCSI-adapters and low-level SCSI drivers do not work correctly with this backend and the
Coolscan scanners. These systems hang when the autofocus command is send to the Scanner.
To see a list of which card/driver combinations work or don't work have a look at:
.I http://andreas.rick.free.fr/sane/autofocus.html.
.SH FILES
.TP
The backend configuration file:
.I @CONFIGDIR@/coolscan.conf
.TP
The static library implementing this backend:
.I @LIBDIR@/libsane\-coolscan.a
.TP
The shared library implementing this backend:
.I @LIBDIR@/libsane\-coolscan.so
(present on systems that support dynamic loading)
.SH ENVIRONMENT
.TP
.B SANE_DEBUG_COOLSCAN
If the library was compiled with debug support enabled, this environment
variable controls the debug level for this backend. E.g., a value of 128
requests all debug output to be printed. Smaller levels reduce verbosity.
Examples:
On bash:
.br
export SANE_DEBUG_COOLSCAN=8
On csh:
.br
setenv SANE_DEBUG_COOLSCAN 8
.SH BUGS
The autofocus command does not work with some SCSI card/driver combinations.
.PP
The gamma table is not implemented for the LS1000 yet.
.PP
The dust-removal is not working yet.

.SH THANKS TO
Didier Carlier \- For writing the original Coolscan backend (without it I would not have started this).
.PP
Oliver Rauch \- For adapting xsane so quickly to the infrared stuff.
.PP
All the other people working on SANE.
