Ubuntu Manpage: sane-teco1 - SANE backend for TECO / RELISYS scanners

NAME

       sane-teco1 - SANE backend for TECO / RELISYS scanners

DESCRIPTION

The sane-teco1 library implements a SANE (Scanner Access Now Easy) backend that provides
access to some TECO SCSI flatbed scanners. This backend should be considered beta-quality
software! TECO scanners are sold under various brands like RELISYS, PIOTECH, TRUST. This
backend may or may not support yours.

The scanners that should work with this backend are:

Dextra DF-4830T VM4542 untested
Dextra DF-1200T+ VM3530+ untested
Dextra DF-9624 VM6530+ untested

Note that the untested scanner will not be directly supported. You should contact the
author for that.

The TECO VM number can usually be found at the back of the scanner. It is also part of the
FCC ID. sane-find-scanner -v will also show the SCSI inquiry, and if it is a TECO
scanner, the name will be there too.

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.

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

scanimage --help -d teco1

Scan Mode

--mode Black & White|Grayscale|Color
Selects the basic mode of operation of the scanner. Valid choices are Black &
White, Grayscale and Color.

The Black & White mode is for 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..600
Selects the resolution for a scan. The scanner can do all resolutions between 1 and
600, in increments of 1.

Geometry options

-l -t -x -y
Controls 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.

Enhancement options

--custom-gamma
(color mode only) 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 256 bytes long. Color mode only.

--green-gamma-table
Can be used to download a user defined gamma table for the green channel. The
table must be 256 bytes long. Color mode only.

--blue-gamma-table
Can be used to download a user defined gamma table for the blue channel. The table
must be 256 bytes long. Color mode only.

--preview
Requests a preview scan. The resolution used 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/teco1.conf supports only one item: the device  name  to
       use (eg /dev/scanner).

FILES

       /usr/lib/x86_64-linux-gnu/sane/libsane-teco1.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/sane/libsane-teco1.so
              The  shared  library  implementing  this  backend  (present on systems that support
              dynamic loading).

ENVIRONMENT

       SANE_DEBUG_TECO1
              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

       None known.
