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 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 backend 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 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 (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/lib64/sane/libsane-teco3.a The static library implementing this backend. /usr/lib64/sane/ 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 imple- ments what the scanner can support. BUGS
Not much. SEE ALSO
