|

.IX sane-avision
|
||
|
||
.SH NAME
|
||
sane-avision \- SANE backend for original Avision and Avision OEM scanners
|
||
(HP, Minolta, Mitsubishi, UMAX and possibly more) flatbed scanners
|
||
|
||
.SH ABOUT THIS FILE
|
||
|
||
This file only is a short descripton of the avision-backend for sane!
|
||
|
||
.SH DESCRIPTION
|
||
The
|
||
.B 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.
|
||
|
||
.SH CONFIGURATION
|
||
|
||
The configuration file for this backend resides in
|
||
@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:
|
||
|
||
.B I suggest you hold one hand on the power-button of the scanner while you try
|
||
the first scans!

|
||
|
||
- force-a4:
|
||
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 retun the area in a unkown format our backend
|
||
doesn't recongize yet.
|
||
|
||
- 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.
|
||
|
||
- disable-calibration:
|
||
Disables the scanner's color calibration. You
|
||
might try this if your scans hang or only produces
|
||
random garbage.
|
||
|
||
- one-calib-only:
|
||
When this option is enabled, the backend will only
|
||
perform a calibration when the backend is initialized
|
||
and not before each scan. This might extend the life
|
||
of the CCD, but does not work reliable with the newer
|
||
USB scanners (they hang sometimes or return garbage
|
||
image data). So this option should be used with care.
|
||
|
||
- old-calibration:
|
||
This enables the use of the old calibration code for
|
||
testing purposes.
|
||
|
||
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 special
|
||
.RE
|
||
.PP
|
||
Where
|
||
.I 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
|
||
.IR sane-find-scanner
|
||
helps to find out the correct device. Under Linux, such a device name
|
||
could be
|
||
.I /dev/sga
|
||
or
|
||
.IR /dev/sge ,
|
||
for example. See sane-scsi(5) for details.
|
||
|
||
Note: Since the backend does only use the scsi interface
|
||
for scanner access, you need a scsi emulation for
|
||
USB devices such as the HP 5300, HP 7400 or Minolta
|
||
film-scanners. The kernel module is named hpusbscsi
|
||
and present in the latest 2.4 and 2.5 kernels.
|
||
|
||
.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
