     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 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 Scan-
          ner.  To see a list of which card/driver combinations work
          or don't work have a look at:

          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.
