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 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:
	      /etc/sane.d/coolscan.conf

       The static library implementing this backend:
	      /usr/lib64/sane/libsane-coolscan.a

       The shared library implementing this backend:
	      /usr/lib64/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.
