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 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:

    #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 can set the permissions of  that
   device, have a look at sane-scsi(5).

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/x86_64-linux-gnu/sane/libsane-coolscan.a

   The shared library implementing this backend:
          /usr/lib/x86_64-linux-gnu/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.

          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.
