sane-matsushita(5) SANE Scanner Access Now Easysane-matsushita(5)NAMEsane-matsushita - SANE backend for Panasonic KV-SS high
speed scanners
DESCRIPTION
The sane-matsushita library implements a SANE (Scanner
Access Now Easy) backend that provides access to some
Panasonic KV-SS high speed scanners. This backend is sta-
ble.
At present, the following scanners are known to work with
this backend:
Product id
--------------
KV-SS 25
KV-SS 25D
Other Panasonic high speed scanners may or may not work
with that backend.
Valid command line options and their syntax can be listed
by using
scanimage --help -d matsushita
Scan Mode
--mode selects the basic mode of operation of the scanner.
--resolution
selects the resolution for a scan. Each model sup-
ports all or a subset of these resolutions: 100,
150, 200, 240, 300, 360, 400.
--duplex
indicates whether to scan both side of the sheet.
--feeder-mode
selects the number of pages to scan (one or until
the tray is empty).
Geometry
--paper-size A4|...|Legal|Letter [A4]
options selects the area to scan. It adjust the -l
-t-x-y options accordingly. It does not need to
be the real size of the paper.
-l -t -x -y
control the scan area: -l sets the top left x coor-
dinate, -t the top left y coordinate, -x selects
the width and -y the height of the scan aea. All
parameters are specified in milimeters. It is pos-
sible to use the option --paper-size instead.
Enhancement
--brightness
controls the brightness of the acquired image. The
value varies from 1 to 255, or less, depending on
the scanner model.
--contrast
controls the contrast of the acquired image. Some
models do not support that option.
--automatic-threshold
automatically sets brightness, contrast, white
level, gamma, noise reduction and image emphasis.
These options are not available when automatic-
threshold is in use.
--halftone-pattern
option sets the tonal gradation for the halftone
mode. Pattern downloading is not implemented by the
backend.
--autoseparation
provides automatic separation of text and images.
--white-level
option indicate the source of the white base.
--noise-reduction
reduces the isolated dot noise. This option is not
supported by all scanners.
--image-emphasis
option sets the image emphasis. Some selection are
not available on all scanners.
--gamma
options set the gamma curve. It is only valid for
Gray modes, and is not available on all scanners.
Gamma downloading is not implemented by the back-
end.
CONFIGURATION FILE
The configuration file /usr/freeware/etc/sane.d/mat-
sushita.conf supports the device name to use (eg
/dev/scanner) and the scsi option to autodetect the scan-
ners supported.
FILES
/usr/freeware/lib32/sane/libsane-matsushita.a
The static library implementing this backend.
/usr/freeware/lib32/sane/libsane-matsushita.so
The shared library implementing this backend (pre-
sent on systems that support dynamic loading).
ENVIRONMENT
SANE_DEBUG_MATSUSHITA
If the library was compiled with debug support
enabled, this environment variable controls the
debug level for this backend. E.g., a value of 128
requests all debug output to be printed. Smaller
levels reduce verbosity.
LIMITATIONS
Memory in the KV-SS 25
The KV-SS 25 has not enough internal memory to scan
a whole A4 page in duplex mode at high densities.
The frontend will return a memory error in that
case. Apparently, the KV-SS 25D has not that prob-
lem.
Pattern and gamma downloading
The scanner, with the proper firmware, can download
a halftone pattern and a gamma table. This is not
implemented.
Sub-areas
The scanner can support up to 3 sub-areas on each
side to define some more precise enhancment
options. This is not implemented.
Duplex mode
The backend does not support the setting of differ-
ent options for each side. The scan will occur with
the same options (halftone pattern, brightness,
image emphasis) for both sides.
SCANNING EXAMPLE
To date, the only frontend capable of using this scanner
at full speed is scanadf.
A scanadf command line would be:
scanadf -d matsushita --output-file scan%04d.pbm --start-
count 0 --duplex--resolution 300 --feeder-mode="All
pages" --paper-size="A4"
BUGS
None known.
