sane-teco2 - SANE backend for TECO / RELISYS scanners

|
<H2>DESCRIPTION</H2>
|
|
|
|
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.
|
|
<P>
|
|
|
|
The scanners that should work with this backend are:

<P>
|
|
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.
|
|
<P>
|
|
Note that the untested scanner will not be directly supported. You
|
|
should contact the author for that.
|
|
<P>
|
|
The TECO VM number can usually be found at the back of the
|
|
scanner. It is also part of the FCC ID.
|
|
<P>
|
|
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.
|
|
<P>
|
|
<BR>
|
|
|
|
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.
|
|
<P>
|
|
Valid command line options and their syntax can be listed by using

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.

Lineart and Gray

|
|
between 1 and 600, in increments of 1.

|

<P>
|

Color
|

selects the resolution for a scan. The scanner can do only the

resolutions listed.
|
|
<P>
|
|
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%

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.
|
|
<DT id="20"><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.

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.
