## NAME

           sane-coolscan - SANE backend for Nikon film-scanners

## ABOUT THIS FILE

           This file is a short descripton of the coolscan-backend for sane!

## DESCRIPTION

           The  sane-coolscan  library implements a SANE backend that provides the
           interface to the following Nikon Coolscan Film  scanners:  Nikon  LS20,
           LS30, LS1000, LS2000.

           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 carefull when using it  the  first
           time.

## CONFIGURATION

           The    configuration    file    for    this    backend    resides    in
           /usr/local/etc/sane.d/coolscan.conf.

           Its contents 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:

            #scsi Vendor Model Type
            scsi Nikon * Scanner
            /dev/scanner

           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 have to set the permissions of that device, have a look  at
           sane-scsi.

## 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  dont  work   have   a   look   at:

## FILES

           The backend configuration file:
            /usr/local/etc/sane.d/coolscan.conf.

           The static library implementing this backend:
            /usr/local/lib/sane/libsane-coolscan.a

           The shared library implementing this backend:
            /usr/local/lib/sane/libsane-coolscan.so
            (present on systems that support dynamic loading)

## ENVIRONMENT

           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: SANE_DEBUG_COOLSCAN values

           Examples:
            on bash:
            export SANE_DEBUG_COOLSCAN=8
            on csh
            setenv SANE_DEBUG_COOLSCAN 8

## BUGS

            The autofocus command does not work with some SCSI card/driver  combi-
           nations
            The gamma table is not implemented for the LS1000 yet.
            The dust-removal is not working yet

## THANKS TO

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