NAME
     sane-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 Pana-
     sonic KV-SS high speed scanners. 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 available (ie no color, no high resolution, no automatic
     cropping). Basically, 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 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  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.


     -l -t -x -y
          control the scan area: -l sets the top left  x  coordi-
          nate,  -t  the  top  left  y coordinate, -x selects the
          width and -y the height of the scan area.  All  parame-
          ters  are  specified  in millimeters. It is possible 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 sup-
          ported 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/sane/libsane-matsushita.a
          The static library implementing this backend.

     /usr/lib/sane/libsane-matsushita.so
          The shared library implementing this  backend  (present
          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 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 imple-
          mented.

     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.
