.SH NAME
|
|
sane\-avision \- SANE backend for original Avision and Avision OEM scanners
|
|
(HP, Minolta, Mitsubishi, UMAX and possibly more) flatbed and film scanners.
|
|
|
|
.SH ABOUT THIS FILE
|
|
|
|
This file is a short descripton for the avision-backend shipped with SANE.
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-avision
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to various Avision scanners and the Avision OEM
|
|
scanners labelled by HP, Minolta, Mitsubishi or Fujitsu.
|
|
|
|
It is fully big-endian aware and in every-day use on PowerPC and SPARC
|
|
systems.
|
|
|
|
.B I suggest you hold one hand on the power-button of the scanner while
|
|
you try the first scans \- especially with film-scanners!
|
|
|
|
.SH CONFIGURATION
|
|
|
|
The configuration file for this backend resides in
|
|
.IR @CONFIGDIR@/avision.conf .
|
|
|
|
Its contents is a list of device names that correspond to Avision and Avision
|
|
compatible scanners and backend-options. Empty lines and lines starting with
|
|
a hash mark (#) are ignored. A sample configuration file is shown below:
|

|
force\-a4:
|
|
Forces the backend to overwrite the scanable area
|
|
returned by the scanner to ISO A4. Scanner that are
|
|
known to return bogus data are marked in the backend
|
|
so if you need this option please report this to the
|
|
backend maintainer. USE WITH CARE!

|

|
so if you need this option please report this to the

|
|
.TP
|
|
disable\-gamma\-table:
|
|
Disables the usage of the scanner's gamma-table. You
|
|
might try this if your scans hang or only produces
|
|
random garbage.
|
|
.TP
|
|
disable\-calibration:
|
|
Disables the scanner's color calibration. You
|
|
might try this if your scans hang or only produces
|
|
random garbage.
|
|
.TP
|
|
Note:
|
|
Any option above modifies the default code-flow
|
|
for your scanner. The options should only be used
|
|
when you encounter problems with the default be-
|
|
haviour of the backend. Please report the need of
|
|
options to the backend-author so the backend can
|
|
be fixed as soon as possible.
|
|
|
|
.SH "DEVICE NAMES"
|
|
This backend expects device names of the form:
|
|
.PP
|
|
.RS
|
|
.I scsi scsi-spec
|
|
|
|
.I usb usb-spec
|
|
.RE
|
|
.PP
|
|
Where
|
|
.I scsi-spec
|
|
is the path-name to a special device or a device ID for the device that
|
|
corresponds to a SCSI scanner. The special device name must be a generic
|
|
SCSI device or a symlink to such a device, for example on Linux "/dev/sga"
|
|
or "/dev/sg0". The device ID is the ID returned by the scanner, for example
|
|
"HP" or "AVISION". See sane\-scsi(5) for details.
|
|
.TP
|
|
Note:
|
|
Since the backend now includes native USB access,
|
|
it is no longer needed \- even considered obsolete \-
|
|
to access USB scanner via the SCSI emulation (named
|
|
hpusbscsi on Linux) for Avision USB devices such as
|
|
the HP 53xx, HP 74xx or Minolta film-scanners.
|
|
.PP
|
|
.I usb-spec
|
|
is the USB device name, the vendor/product ID pair or the name used by
|
|
libusb corresponding to the USB scanner. For example "0x03f0 0x0701" or
|
|
"libusb:002:003". See sane\-usb(5) for details.
|
|
|
|
The program
|
|
.IR sane\-find\-scanner
|
|
helps to find out the correct scsi or usb device name.
|
|
|
|
A list with supported devices is built into the avision backend so
|
|
normally specifying an ID should not be necessary.
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @CONFIGDIR@/avision.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I @LIBDIR@/libsane\-avision.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-avision.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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 configuration file
|
|
is searched in two default directories: first, the current working
|
|
directory (".") and then in @CONFIGDIR@. 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
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"@CONFIGDIR@" being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_AVISION
|
|
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. The debug
|
|
level 7 is the author's prefered value to debug backend problems.
|
|
|
|
Example:
|
|
export SANE_DEBUG_AVISION=7
|
