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 @CONFIGDIR@/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:

FILES
       The backend configuration file:
              @CONFIGDIR@/coolscan.conf

       The static library implementing this backend:
              @LIBDIR@/libsane-coolscan.a

       The shared library implementing this backend:
              @LIBDIR@/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.

       All the other people working on SANE.
