NAME
sane-coolscan - SANE backend for Nikon film-scannersABOUT 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 don't work have a look at: andreas.rick.free.fr/sane/autofocus.html
FILES
- The backend configuration file:
- /etc/sane.d/coolscan.conf
- The static library implementing this backend:
- /usr/lib/arch_triplet/sane/libsane-coolscan.a
- The shared library implementing this backend:
-
/usr/lib/arch_triplet/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.
