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
   /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  don't  work  have   a   look   at:
   http://andreas.rick.free.fr/sane/autofocus.html.

FILES

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

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

   The shared library implementing this backend:
          /usr/lib/arch_triplet/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
   combinations

   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.
