sane-matsushita - SANE backend for Panasonic KV-SS high speed scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-matsushita</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to some Panasonic KV-SS high speed scan-
|
|
ners. This backend is stable.
|
|
|
|
At present, the following scanners are known to work with this backend:
|
|
|
|
Product id

--------------
|

KV-SS25

KV-SS25D

(*) WARNING: None of the advanced options of these scanners are avail-
|
|
able (ie no color, no high resolution, no automatic cropping). Basi-
|
|
cally, the driver does no more than what it does for the KV-SS25. I
|
|
don't have access to such scanners, and thus cannot add these options.
|
|
|
|
Other Panasonic high speed scanners may or may not work with that back-
|
|
end.
|
|
|
|
Valid command line options and their syntax can be listed by using
|
|
|
|
scanimage --help -d matsushita
|
|
|
|
<B>Scan</B> <B>Mode</B>
|
|
|
|
<B>--mode</B> selects the basic mode of operation of the scanner.
|
|
|
|
<B>--resolution</B>
|
|
selects the resolution for a scan. Each model supports all or a
|
|
subset of these resolutions: 100, 150, 200, 240, 300, 360, 400.
|
|
|
|
<B>--duplex</B>
|
|
indicates whether to scan both side of the sheet.
|
|
|
|
<B>--feeder-mode</B>
|
|
selects the number of pages to scan (one or until the tray is
|
|
empty).
|
|
|
|
<B>Geometry</B>
|
|
|
|
<B>--paper-size</B> <B>A4|...|Legal|Letter</B> <B>[A4]</B>
|
|
options selects the area to scan. It adjust the <B>-l</B> <B>-t</B> <B>-x</B> <B>-y</B>
|
|
options accordingly. It does not need to be the real size of the
|
|
paper.
|
|
|
|
<B>-l</B> <B>-t</B> <B>-x</B> <B>-y</B>
|
|
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 area. All parameters are specified in millimeters. It
|
|
is possible to use the option <I>--paper-size</I> instead.
|
|
|
|
<B>Enhancement</B>
|
|
|
|
<B>--brightness</B>
|
|
controls the brightness of the acquired image. The value varies
|
|
from 1 to 255, or less, depending on the scanner model.
|
|
|
|
<B>--contrast</B>
|
|
controls the contrast of the acquired image. Some models do not
|
|
support that option.
|
|
|
|
<B>--automatic-threshold</B>
|
|
automatically sets brightness, contrast, white level, gamma,
|
|
noise reduction and image emphasis. These options are not avail-
|
|
able when automatic-threshold is in use.
|
|
|
|
<B>--halftone-pattern</B>
|
|
option sets the tonal gradation for the halftone mode. Pattern
|
|
downloading is not implemented by the backend.
|
|
|
|
<B>--autoseparation</B>
|
|
provides automatic separation of text and images.
|
|
|
|
<B>--white-level</B>
|
|
option indicate the source of the white base.
|
|
|
|
<B>--noise-reduction</B>
|
|
reduces the isolated dot noise. This option is not supported by
|
|
all scanners.
|
|
|
|
<B>--image-emphasis</B>
|
|
option sets the image emphasis. Some selection are not available
|
|
on all scanners.
|
|
|
|
<B>--gamma</B>
|
|
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.

|
|
<H2>CONFIGURATION FILE</H2><PRE>
|
|
The configuration file <I>/usr/local/etc/sane.d/matsushita.conf</I> supports
|
|
the device name to use (eg <I>/dev/scanner</I>) and the SCSI option to auto-
|
|
detect the scanners supported.
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/lib/sane/libsane-matsushita.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-matsushita.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_DEBUG_MATSUSHITA</B>
|
|
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.
|

|
|
<H2>LIMITATIONS</H2><PRE>
|
|
<B>Memory</B> <B>in</B> <B>the</B> <B>KV-SS</B> <B>25</B>
|
|
The KV-SS 25 has not enough internal memory to scan a whole A4
|
|
page in duplex mode at high resolution. The frontend will return
|
|
a memory error in that case. Apparently, the KV-SS 25D has not
|
|
that problem.
|
|
|
|
<B>Pattern</B> <B>and</B> <B>gamma</B> <B>downloading</B>
|
|
The scanner, with the proper firmware, can download a halftone
|
|
pattern and a gamma table. This is not implemented.
|
|
|
|
<B>Sub-areas</B>
|
|
The scanner can support up to 3 sub-areas on each side to define
|
|
some more precise enhancement options. This is not implemented.
|
|
|
|
<B>Duplex</B> <B>mode</B>
|
|
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.
|
|
|
|
|
|
</PRE>
|
|
<H2>SCANNING EXAMPLE</H2><PRE>
|
|
To date, the only frontend capable of using this scanner at full speed
|
|
is <B><A HREF="scanadf.1.html">scanadf(1)</A></B>.
|
|
|
|
A <B><A HREF="scanadf.1.html">scanadf(1)</A></B> 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"
