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/freeware/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 per-
missions 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 combina-
tions work or dont work have a look at:

FILES
The backend configuration file:
/usr/freeware/etc/sane.d/coolscan.conf.
The static library implementing this backend:
/usr/freeware/lib32/sane/libsane-coolscan.a
The shared library implementing this backend:
/usr/freeware/lib32/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 out-
put 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

Didier Carlier - For writing the original Coolscan back-
end (without it I would not have started this)

infrared stuff.
