.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 beta-quality
|
|
software! TECO scanners are sold under
|
|
various brands like Mustek, Relisys, Piotech, Primax, TRUST.
|
|
This backend may or may not support yours.
|
|

|

The scanners that should work with this backend are:

For all these scanners, lineart and gray mode work
|
|
well. However, most of them do not support more than a handful of
|
|
resolutions in color mode. See the backend home page (under AUTHOR)
|
|
for the exact status of each scanner.
|
|
|
|
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, xsane, quiteinsane or kooka.
|
|
|

|
|
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 Lineart
|
|
,
|
|
.I Gray
|
|
and
|
|
.I Color
|
|
The Lineart mode is black and white only (1 bit). Gray mode
|
|
will produce 256 levels of gray (8 bits). Color will produce a 24 bits
|
|
color image.
|
|
|
|
.TP
|
|
.B \-\-resolution
|
|
Lineart and Gray
|
|
selects the resolution for a scan. The scanner can do all resolutions
|
|
between 1 and 600, in increments of 1.
|
|
|
|
|
|
Color
|
|
selects the resolution for a scan. The scanner can do only the
|
|
resolutions listed.
|
|
|
|
All values with ydpi > 300 (300 x 600) or 600 (600 x 1200) result in
|
|
a wrong proportion for the scan. The proportion can be adjusted with
|
|
the following imagemagick command:
|
|
convert \-geometry (dpi/max_xdpi * 100%)x100%
|
|
max_xdpi is for the vm3575 constant with 300 dpi
|
|
e.g. 600dpi adjust with: convert \-geometry 200%x100%
|
|
|
|
.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.

.B Enhancement options
|
|
|
|
.TP
|
|
.B \-\-custom\-gamma (no custom gamma option for the VM3564 and VM356A)
|
|
(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 \-\-white\-level\-r
|
|
(VM3564, VM356A, VM3575 and VM6575 only) Selects what red radiance level should be
|
|
considered "white", when scanning some sheets by changing the calibration
|
|
value loaded into the scanner. Scale 0..64 in steps of 1.
|
|
|
|
.TP
|
|
.B \-\-white\-level\-g
|
|
(VM3564, VM356A, VM3575 and VM6575 only) Selects what green radiance level should be
|
|
considered "white", when scanning some sheets by changing the calibration i
|
|
value loaded into the scanner. Scale 0..64 in steps of 1.
|
|
|
|
.TP
|
|
.B \-\-white\-level\-b
|
|
(VM3564, VM356A, VM3575 and VM6575 only) Selects what blue radiance level should be
|
|
considered "white", when scanning some sheets by changing the calibration
|
|
value loaded into the scanner. Scale 0..64 in steps of 1.
|
|
|
|
.TP
|
|
.B \-\-preview
|
|
requests a preview scan. The resolution used for that scan is 50 dpi
|
|
(for VM356A and VM6575 75 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.
|
|
.TP
|
|
.B SANE_TECO2_CAL_ALGO
|
|
Either 0 or 1. Selects the algorithm for the calibration. A
|
|
value of 1 seems to give better scans on the VM356A, VM3575.
|
|
Feedback on it is welcome.
|
|
For VM3564, VM356A, VM3575, VM6575 default 1.
|
|
For other supported types default 0.
|
|
|
|
|
|
.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.
