NAME
       sane-coolscan - SANE backend for Nikon film-scanners


ABOUT THIS FILE
       This file is a short descripton 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 carefull 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:
       http://andreas.rick.free.fr/sane/autofocus.html.




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
       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.
