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: http://andreas.rick.free.fr/sane/autofocus.html.

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.
