sane-teco3(5)		 SANE Scanner Access Now Easy		 sane-teco3(5)

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 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 lev‐
	      els of gray (8 bits). Color will produce a 24 bits color image.

       --resolution
	      selects  the resolution for a scan. The scanner can do all reso‐
	      lutions 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 infor‐
       mation: the device name to use (eg /dev/scanner).

FILES
       /usr/lib64/sane/libsane-teco3.a
	      The static library implementing this backend.

       /usr/lib64/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 imple‐
       ments what the scanner can support.

BUGS
       Not much.
