.SH NAME
|
|
sane-teco2 - SANE backend for TECO / RELISYS scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane-teco2
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to some TECO SCSI flatbed scanners. This backend
|
|
should be considered
|
|
.B alpha-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:

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.
|
|
|
|
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

.B Scan Mode
|
|
|
|
.TP
|
|
.B --mode
|
|
selects the basic mode of operation of the scanner valid choices are
|
|
.I Black & White
|
|
,
|
|
.I Grayscale
|
|
and
|
|
.I 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.
|
|
|
|
.TP
|
|
.B --resolution
|
|
selects the resolution for a scan. The scanner can do all resolutions
|
|
between 1 and 600, in increments of 1.
|
|
|
|
|
|
.TP
|
|
.B Geometry options
|
|
|
|
.TP
|
|
.B -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.

.TP
|
|
.B Enhancement options
|
|
|
|
.TP
|
|
.B --custom-gamma
|
|
(color mode only) allows the user to specify a gamma table (see the
|
|
next 3 parameters).
|
|
|
|
.TP
|
|
.B --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.
|
|
|
|
.TP
|
|
.B --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.
|
|
|
|
.TP
|
|
.B --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.
|
|
|
|
|
|
.TP
|
|
.B --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".
|
|
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file @CONFIGDIR@/teco2.conf supports only one information: the device name to use (eg /dev/scanner).
|
|
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @LIBDIR@/libsane-teco2.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane-teco2.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B SANE_DEBUG_TECO2
|
|
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.
|
|
|
|
|
|
.SH 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.
|
|
|
|
|
|
.SH BUGS
|
|
|
|
Plenty. Parts of this backend are still under development.
