sane-avision - SANE backend for Avision (and OEM HP, Minolta) flatbed
This file only is a short descripton of the avision-backend for sane!
The sane-avision library implements a SANE (Scanner Access Now Easy)
backend that provides access to Avision flatbed scanners and the Avision
OEM scanners labelled with HP and Minolta.
The configuration file for this backend resides in
Its contents is a list of device names that correspond to Avision and
Avision compatible scanners. Empty lines and lines starting with a hash
mark (#) are ignored. A sample configuration file is shown below:
I suggest you hold one hand on the power-button of the scanner while
you try the first scans!

Forces the backend to overwrite the scanable area
returned by the scanner. This might be needed for
the AV 630 which returns no area - or newer scanners
which retuns the area in a unkown format our backend
doesn't recongize yet.
Tells the backend to use USB scanner - which do not
work correctly yet.
Disables the usage of the scanner's gamma-table. You
might try this if your scans hang, or only produces
This backend expects device names of the form:
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

The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
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 configuration
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 explicitly 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
SANE_DEBUG_AVISION [Toc] [Back]
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_AVISION=4
