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: Vendor Model TECO model status ---------------------- -------------- ----------- Relisys AVEC 2400 VM3520 tested Relisys AVEC 2412 VM3520+ tested Relisys AVEC 4800 VM4530 untested Relisys AVEC 4816 VM4530+ untested Relisys RELI 2400 VM3530 untested Relisys RELI 2412 VM3530+ tested Relisys RELI 2412 VM3530+ untested Relisys RELI 4816 VM4540 tested Relisys RELI 4830 VM4542 tested Relisys RELI 9600 VM6530 untested Relisys RELI 9612 VM6530* untested Relisys RELI 9624 VM6530+ untested Relisys RELI 9630 VM6540 untested Relisys RELI DS15 VM3440 untested Relisys RELI DS6 VM3420 untested Dextra DF-600P VM3510 tested 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 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 teco1 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 600, 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 256 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 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. --dither (Black & White only) select the dither mask to use. Possible values are Line art , 2x2 , 3x3 , 4x4 bayer , 4x4 smooth , 8x8 bayer , 8x8 smooth , 8x8 horizontal and 8x8 vertical --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/teco1.conf supports only one information: the device name to use (eg /dev/scanner). FILES
/usr/lib64/sane/libsane-teco1.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_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 imple- ments what the scanner can support. BUGS
None known. SEE ALSO
