.IX sane-avision
|
||
|
||
.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:
|
||
|
||

||

|
||
|
||
.TP
|
||
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!
|
||
.TP
|
||
force-a3:
|
||
Forces the backend to overwrite the scanable area
|
||
returned by the scanner to ISO A3. 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!
|
||
.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
|
||

||
