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.
