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 FCC ID.

   The options the backend supports can either be selected through command line options to programs like scanimage(1) or through GUI elements in xscanimage(1) or xsane(1).

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

OPTIONS

   Valid command line options and their syntax can be listed by using:

          scanimage --help -d teco3

   Scan Mode

   --mode Black & White|Grayscale|Color
          Selects the basic mode of operation of the scanner.  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-bit color image.

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

   --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".

   Geometry options

   -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 area.  All parameters are specified
          in millimeters by default.

OPTIONS FOR COLOR MODE ONLY

   --custom-gamma
          Allows the user to specify a gamma table (see the next 3 parameters).

   --red-gamma-table
          Can be used to download a user defined gamma table for the red channel. The table must be 1024 bytes long.

   --green-gamma-table
          Can be used to download a user defined gamma table for the green channel. The table must be 1024 bytes long.

   --blue-gamma-table
          Can be used to download a user defined gamma table for the blue channel. The table must be 1024 bytes long.

CONFIGURATION FILE

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

FILES

   /usr/lib/x86_64-linux-gnu/sane/libsane-teco3.a
          The static library implementing this backend.

   /usr/lib/x86_64-linux-gnu/sane/libsane-teco3.so
          The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

   SANE_DEBUG_TECO3
          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.
