sane-teco2 - SANE backend for TECO / RELISYS scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-teco2</B> 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</B> 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:
|
|
|
|
Vendor Model TECO model status
|

|
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
|
|
scanimage --help -d teco2
|
|
|
|
<B>Scan</B> <B>Mode</B>
|
|
|
|
<B>--mode</B> selects the basic mode of operation of the scanner valid choices
|
|
are <I>Lineart</I> , <I>Gray</I> and <I>Color</I> 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.
|
|
|
|
<B>--resolution</B>
|
|
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 -geome-
|
|
try (dpi/max_xdpi * 100%)x100% max_xdpi is for the vm3575 con-
|
|
stant with 300 dpi e.g. 600dpi adjust with: convert -geometry
|
|
200%x100%
|
|
|
|
<B>Geometry</B> <B>options</B>
|
|
|
|
<B>-l</B> <B>-t</B> <B>-x</B> <B>-y</B>
|
|
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.

|
|
(color mode only) allows the user to specify a gamma table (see
|
|
the next 3 parameters).
|
|
|
|
<B>--red-gamma-table</B>
|
|
(color mode only) can be used to download a user defined gamma
|
|
table for the red channel. The table must be 256 bytes long.
|
|
|
|
<B>--green-gamma-table</B>
|
|
(color mode only) can be used to download a user defined gamma
|
|
table for the green channel. The table must be 256 bytes long.
|
|
|
|
<B>--blue-gamma-table</B>
|
|
(color mode only) can be used to download a user defined gamma
|
|
table for the blue channel. The table must be 256 bytes long.
|
|
|
|
<B>--white-level-r</B>
|
|
(VM3564, VM356A, VM3575 and VM6575 only) Selects what red radi-
|
|
ance level should be considered "white", when scanning some
|
|
sheets by changing the calibration value loaded into the scan-
|
|
ner. Scale 0..64 in steps of 1.
|
|
|
|
<B>--white-level-g</B>
|
|
(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 scan-
|
|
ner. Scale 0..64 in steps of 1.
|
|
|
|
<B>--white-level-b</B>
|
|
(VM3564, VM356A, VM3575 and VM6575 only) Selects what blue radi-
|
|
ance level should be considered "white", when scanning some
|
|
sheets by changing the calibration value loaded into the scan-
|
|
ner. Scale 0..64 in steps of 1.
|
|
|
|
<B>--preview</B>
|
|
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 max-
|
|
imum allowed. The scan mode is user selected. The default is
|
|
"no".

|
|
<H2>CONFIGURATION FILE</H2><PRE>
|
|
The configuration file /usr/local/etc/sane.d/teco2.conf supports only
|
|
one information: the device name to use (eg /dev/scanner).
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/lib/sane/libsane-teco2.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-teco2.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_DEBUG_TECO2</B>
|
|
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.
|
|
|
|
<B>SANE_TECO2_CAL_ALGO</B>
|
|
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.
|
|
|
|
|
|
</PRE>
|
|
<H2>LIMITATIONS</H2><PRE>
|
|
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.
|
|
|
|
|
|
</PRE>
|
|
<H2>BUGS</H2><PRE>
|
|
Plenty. Parts of this backend are still under development.
