       sane-coolscan - SANE backend for Nikon film-scanners

ABOUT THIS FILE    [Toc]    [Back]

       This file is a short descripton of the coolscan-backend for sane!

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       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:

FILES    [Toc]    [Back]

       The backend configuration file:
	/etc/sane.d/coolscan.conf.

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

       The shared library implementing this backend:
	/usr/lib/sane/libsane-coolscan.so
	(present on systems that support dynamic loading)

ENVIRONMENT    [Toc]    [Back]

       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    [Toc]    [Back]

	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    [Toc]    [Back]

	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.
