sane-leo - SANE backend for LEO Technologies scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-leo</B> library implements a SANE (Scanner Access Now Easy) back-
|
|
end that provides access to some LEO SCSI flatbed scanners. This back-
|
|
end should be considered <B>beta-quality</B> software! LEO scanners were also
|
|
sold under the Across Technologies brand.
|
|
|
|
The scanners that should work with this backend are:
|
|
|
|
Vendor Model status
|
|
---------------------- -----------
|
|
Across FS-1130 tested
|
|
Leo S3 tested
|
|
|
|
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 strange behavior, please report to the backend main-
|
|
tainer or to the SANE mailing list.
|
|
|
|
Valid command line options and their syntax can be listed by using
|
|
scanimage --help -d leo
|
|
|
|
<B>Scan</B> <B>Mode</B>
|
|
|
|
<B>--mode</B> selects the basic mode of operation of the scanner valid choices
|
|
are <I>Black</I> <I>&</I> <I>White</I> , <I>Grayscale</I> and <I>Color</I> The Black & White mode
|
|
is black and white only (1 bit). Grayscale will produce 256 lev-
|
|
els of gray (8 bits). Color will produce a 24 bits color image.
|
|
|
|
<B>--resolution</B>
|
|
selects the resolution for a scan. The scanner can do all reso-
|
|
lutions between 1 and 300, in increments of 1.
|
|
|
|
<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.
|
|
|
|
<B>Enhancement</B> <B>options</B>
|
|
|
|
<B>--custom-gamma</B>
|
|
(grayscale and 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>--halftone</B>
|
|
(Black & White only) select the halftone mask to use. Possible
|
|
values are <I>Diamond</I> , <I>8x8</I> <I>Coarse</I> <I>Fatting</I> , <I>8x8</I> <I>Fine</I> <I>Fatting</I> , <I>8x8</I>
|
|
<I>Bayer</I> and <I>8x8</I> <I>Vertical</I> <I>Line</I>
|
|
|
|
<B>--preview</B>
|
|
requests a preview scan. The resolution used for that scan is 28
|
|
dpi and the scan area is the maximum allowed. The scan mode is
|
|
user selected. The default is "no".

|
|
<H2>CONFIGURATION FILE</H2><PRE>
|
|
The configuration file /usr/local/etc/sane.d/leo.conf supports only one
|
|
information: the device name to use (eg /dev/scanner).
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/lib/sane/libsane-leo.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-leo.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_DEBUG_LEO</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.
|
|
|
|
|
|
</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>
|
|
None known.
