.SH NAME
|
|
sane-matsushita \- SANE backend for Panasonic KV-SS high speed scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B 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 stable.
|
|
.PP
|
|
At present, the following scanners are known to work with this
|
|
backend:

.RE

|
|
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
|
|
.RS
|
|
scanimage --help -d matsushita

|
.B Scan Mode
|
|
|
|
.TP
|
|
.B --mode
|
|
selects the basic mode of operation of the scanner.
|
|
.TP
|
|
.B --resolution
|
|
selects the resolution for a scan. Each model supports all or a subset of these resolutions: 100, 150, 200, 240, 300, 360, 400.
|
|
.TP
|
|
.B --duplex
|
|
indicates whether to scan both side of the sheet.
|
|
.TP
|
|
.B --feeder-mode
|
|
selects the number of pages to scan (one or until the tray is empty).
|
|
|
|
.TP
|
|
.B Geometry
|
|
|
|
.TP
|
|
.B --paper-size A4|...|Legal|Letter [A4]
|
|
options selects the area to scan. It adjust the
|
|
.B -l -t -x -y
|
|
options accordingly. It does not need to be the real size of the paper.
|
|
|
|
.TP
|
|
.B -l -t -x -y
|
|
control the scan area: -l sets the top left x coordinate, -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 possible to use
|
|
the option
|
|
.I --paper-size
|
|
instead.
|
|
|
|
.TP
|
|
.B Enhancement
|
|
|
|
.TP
|
|
.B --brightness
|
|
controls the brightness of the acquired image. The value varies from 1 to 255, or less, depending on the scanner model.
|
|
.TP
|
|
.B --contrast
|
|
controls the contrast of the acquired image. Some models do not support that option.
|
|
.TP
|
|
.B --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.
|
|
.TP
|
|
.B --halftone-pattern
|
|
option sets the tonal gradation for the halftone mode. Pattern downloading is not implemented by the backend.
|
|
.TP
|
|
.B --autoseparation
|
|
provides automatic separation of text and images.
|
|
.TP
|
|
.B --white-level
|
|
option indicate the source of the white base.
|
|
.TP
|
|
.B --noise-reduction
|
|
reduces the isolated dot noise. This option is not supported by all scanners.
|
|
.TP
|
|
.B --image-emphasis
|
|
option sets the image emphasis. Some selection are not available on all scanners.
|
|
.TP
|
|
.B --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 backend.
|
|
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file @CONFIGDIR@/matsushita.conf supports the device name to use (eg /dev/scanner) and the scsi option to autodetect the scanners supported.
|
|
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @LIBDIR@/libsane-matsushita.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane-matsushita.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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.
|
|
|
|
|
|
.SH LIMITATIONS
|
|
.TP
|
|
.B 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 problem.
|
|
.TP
|
|
.B Pattern and gamma downloading
|
|
The scanner, with the proper firmware, can download a halftone pattern
|
|
and a gamma table. This is not implemented.
|
|
.TP
|
|
.B 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.
|
|
.TP
|
|
.B Duplex mode
|
|
The backend does not support the setting of different options for each side. The scan will occur with the same options (halftone pattern, brightness, image emphasis) for both sides.
|
|
|
|
|
|
.SH SCANNING EXAMPLE
|
|
To date, the only frontend capable of using this scanner at full speed is
|
|
.B
|
|
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"
