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:

		 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(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 no-
       tice 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	 reso-
	      lutions 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 mil-
	      limeters 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.

       --dither	Line art|2x2|3x3|4x4 bayer|4x4 smooth|8x8 bayer|8x8 smooth|8x8
       horizontal|8x8 vertical
	      Select the dither	mask to	use. Black & White 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  se-
	      lected. The default is "no".

CONFIGURATION FILE
       The  configuration  file	/usr/local/etc/sane.d/teco1.conf supports only
       one item: the device name to use	(eg /dev/scanner).

FILES
       /usr/local/lib/sane/libsane-teco1.a
	      The static library implementing this backend.

       /usr/local/lib/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 en-
	      vironment	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.
