 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:

 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 notice
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 resolutions
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 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 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
selected. The default is "no".



 CONFIGURATION FILE
The configuration file
 @CONFIGDIR@/teco1.conf supports only one item: the device name to use (eg
 /dev/scanner ). 


 FILES

 @LIBDIR@/libsane-teco1.a The static library implementing this backend.


 @LIBDIR@/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
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
implements what the scanner can support.



 BUGS
None known.
