sane-matsushita


DESCRIPTION
       The sane-matsushita 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
                 KV-SS55EX (*)
                 KV-S2025C (*)
                 KV-S2045C (*)
                 KV-S2065L (*)

       (*)  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


       Scan Mode


       --mode selects the basic mode of operation of the scanner.

       --resolution
              selects  the resolution for a scan. Each model supports 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.

              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 avail-
              able 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 backend.



CONFIGURATION FILE
       The  configuration file /etc/sane.d/matsushita.conf supports the device
       name to use (eg /dev/scanner) and the SCSI option  to  auto-detect  the
       scanners supported.



FILES
       /usr/lib/arch_triplet/sane/libsane-matsushita.a
              The static library implementing this backend.

       /usr/lib/arch_triplet/sane/libsane-matsushita.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).



              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.

       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 enhancement options. This is not implemented.

       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.



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.
