NAME
sane-teco2 - SANE backend for TECO / RELISYS scanners
DESCRIPTION
The sane-teco2 library implements a SANE (Scanner Access Now
Easy) backend that provides access to some TECO SCSI flatbedscanners. This backend should be considered beta-quality
software! TECO scanners are sold under various brands like Mustek, Relisys, Piotech, Primax, 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 Super 3 VM3575 good For all these scanners, lineart and gray mode work well. However, most of them do not support more than a handful of resolutions in color mode. See the backend home page (under AUTHOR) for the exact status of each scanner.Note that the untested scanner will not be directly sup-
ported. 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. The options the backend supports can either be selected through command line options to programs like scanimage or through GUI elements in xscanimage, xsane, quiteinsane or kooka. If you have any success with a scanner not listed here, orif 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 usingscanimage --help -d teco2

Scan Mode--mode
selects the basic mode of operation of the scanner valid choices are Lineart , Gray and Color The Lineart mode is black and white only (1 bit). Gray mode will produce 256 levels of gray (8 bits). Color will produce a 24 bits color image.--resolution
Lineart and Gray selects the resolution for a scan. The scanner can do all resolutions between 1 and 600, in increments of 1. Color selects the resolution for a scan. The scanner can do only the resolutions listed. All values with ydpi > 300 (300 x 600) or 600 (600 x 1200) result in a wrong proportion for the scan. Theproportion can be adjusted with the following imagemag-
ick command: convert -geometry (dpi/max_xdpi *
100%)x100% max_xdpi is for the vm3575 constant with 300
dpi e.g. 600dpi adjust with: convert -geometry
200%x100%
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 (no custom gamma option for
(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 256 bytes long.sane-backends 1.0.19Last change: 29 July 2005 2

--green-gamma-table
(color mode only) can be used to download a user defined gamma table for the green channel. The table must be 256 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 256 bytes long.--white-level-r
(VM3564, VM356A, VM3575 and VM6575 only) Selects what red radiance level should be considered "white", when scanning some sheets by changing the calibration value loaded into the scanner. Scale 0..64 in steps of 1.--white-level-g
(VM3564, VM356A, VM3575 and VM6575 only) Selects what green radiance level should be considered "white", when scanning some sheets by changing the calibration i value loaded into the scanner. Scale 0..64 in steps of 1.--white-level-b
(VM3564, VM356A, VM3575 and VM6575 only) Selects what blue radiance level should be considered "white", when scanning some sheets by changing the calibration value loaded into the scanner. Scale 0..64 in steps of 1.--preview
requests a preview scan. The resolution used for that scan is 50 dpi (for VM356A and VM6575 75 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/teco2.conf supports only one information: the device name to use (eg /dev/scanner). FILES/usr/lib/sane/libsane-teco2.a

/usr/lib/sane/libsane-teco2.so
The shared library implementing this backend (present on systems that support dynamic loading). ENVIRONMENTSANE_DEBUG_TECO2
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.SANE_TECO2_CAL_ALGO
Either 0 or 1. Selects the algorithm for the calibra-
tion. A value of 1 seems to give better scans on the VM356A, VM3575. Feedback on it is welcome. For VM3564, VM356A, VM3575, VM6575 default 1. For other supported types default 0. 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
Plenty. Parts of this backend are still under development.SEE ALSO
