NAME

       sane-coolscan - SANE backend for Nikon film-scanners

ABOUT THIS FILE

       This file is a short description 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 careful 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 combina-
       tions

       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.
