sane-coolscan − SANE backend for Nikon film-scanners
This file is a short descripton of the coolscan-backend for sane!
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.
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.
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.
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)
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
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

- For writing the original Coolscan backend (without it I
would not have started this)

stuff.
