SANE Scanner Access Now Easy                        sane-teco3(5)



NAME
     sane-teco3 - SANE backend for TECO / RELISYS scanners

DESCRIPTION
     The sane-teco3 library implements a SANE (Scanner Access Now
     Easy) backend that provides access to some TECO SCSI flatbed
     scanners. This backend should  be  considered  alpha-quality
     software!  TECO  scanners are sold under various brands like
     RELYSIS, PIOTECH, TRUST. This backend may or may not support
     yours.

     The scanners that should work with this backend are:

            Vendor Model                 TECO model   status
            ---------------------------  ----------  ----------
            Relisys Scorpio                VM3552     tested
            Plustek OpticPro 2400SP        VM3552     untested
            PIOTECH Splendeur 3024         VM3552     tested
            Trust Imagery 2400 SP          VM3552     tested
            Trust Imagery 4800 SP]         VM3552     tested
            Trust Imagery 9600 SP          VM3552     untested

     The TECO VM number can usually be found at the back  of  the
     scanner. It is also part of the FC ID.

     The options the backend  supports  can  either  be  selected
     through  command  line options to programs like scanimage or
     through GUI elements in xscanimage or xsane.

     If you have any success with a scanner not listed  here,  or
     if you have any strange behavior, please report to the back-
     end maintainer or to the SANE mailing list.

     Valid command line options and their syntax can be listed by
     using
          scanimage --help -d teco3


     Scan Mode


     --mode
          selects the basic mode  of  operation  of  the  scanner
          valid  choices  are Black & White , Grayscale and Color
          The Black & White mode is black and white only (1 bit).
          Grayscale  will  produce  256  levels of gray (8 bits).
          Color will produce a 24 bits color image.


     --resolution
          selects the resolution for a scan. The scanner  can  do
          all resolutions between 1 and 1200, in increments of 1.

     Geometry options


     -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 by default.



     Enhancement options


     --custom-gamma
          (color mode only) allows the user to  specify  a  gamma
          table (see the next 3 parameters).


     --red-gamma-table
          (color mode only)  can  be  used  to  download  a  user
          defined gamma table for the red channel. The table must
          be 1024 bytes long.


     --green-gamma-table
          (color mode only)  can  be  used  to  download  a  user
          defined  gamma  table  for the green channel. The table
          must be 1024 bytes long.


     --blue-gamma-table
          (color mode only)  can  be  used  to  download  a  user
          defined  gamma  table  for  the blue channel. The table
          must be 1024 bytes long.



     --preview
          requests a preview scan. The resolution used  for  that
          scan  is  22  dpi  and  the  scan  area  is the maximum
          allowed. The scan mode is user selected. The default is
          "no".



CONFIGURATION FILE
     The configuration file /etc/sane.d/teco3.conf supports  only
     one information: the device name to use (eg /dev/scanner).

FILES
     /usr/lib/sane/libsane-teco3.a
          The static library implementing this backend.

     /usr/lib/sane/libsane-teco3.so
          The shared library implementing this  backend  (present
          on systems that support dynamic loading).



ENVIRONMENT
     SANEDEBUGTECO3
          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
     The windows TWAIN driver has many  more  options  than  this
     SANE  backend.  However  they are only software adjustments.
     This backend only implements what the scanner can support.



BUGS
     Not much.
