sane-tamarack(5)					   SANE Scanner Access Now Easy 					  sane-tamarack(5)

NAME
sane-tamarack - SANE backend for Tamarack flatbed scanners DESCRIPTION
The sane-tamarack library implements a SANE (Scanner Access Now Easy) backend that provides access to the following Tamarack flatbed scan- ners: Artiscan 6000C Artiscan 8000C Artiscan 12000C DEVICE NAMES
This backend expects device names of the form: special Where special is the path-name for the special device that corresponds to a SCSI scanner. The special device name must be a generic SCSI device or a symlink to such a device. The program sane-find-scanner helps to find out the correct device. Under Linux, such a device name could be /dev/sga or /dev/sge, for example. See sane-scsi(5) for details. FILES
/etc/sane.d/tamarack.conf The backend configuration file (see also description of SANE_CONFIG_DIR below). /usr/lib64/sane/libsane-tamarack.a The static library implementing this backend. /usr/lib64/sane/libsane-tamarack.so The shared library implementing this backend (present on systems that support dynamic loading). ENVIRONMENT
SANE_CONFIG_DIR This environment variable specifies the list of directories that may contain the configuration file. Under UNIX, the directories are separated by a colon (`:'), under OS/2, they are separated by a semi-colon (`;'). If this variable is not set, the configura- tion file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value of the environment variable ends with the directory separator character, then the default directories are searched after the explic- itly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".", and "/etc/sane.d" being searched (in this order). SANE_DEBUG_TAMARACK If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. Higher debug levels increase the verbosity of the output. Example: export SANE_DEBUG_TAMARACK=4 SEE ALSO
