sane-abaton - SANE backend for Abaton flatbed scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-abaton</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to Abaton flatbed scanners. At present,
|
|
only the Scan 300/GS (8bit, 256 levels of gray) is fully supported, due
|
|
to the absence of programming information. The Scan 300/S (black and
|
|
white) is recognized, but support for it is untested.
|
|
|
|
If you own a Abaton scanner other than the ones listed above that works
|
|
with this backend, or if you own an Abaton scanner that does not work
|
|
with this backend, please contact <I>sane-devel@lists.alioth.debian.org</I>
|
|
with the model number, so that arrangements can be made to include sup-
|
|
port for it. Have a look at http://www.sane-project.org/mail-
|
|
ing-lists.html concerning subscription to sane-devel.
|
|
|
|
Abaton is out of business, and these scanners are not supported by
|
|
Everex (the parent company of Abaton), nor is there any programming
|
|
information to be found. This driver is therefore based on information
|
|
obtained by running Abaton's scanning desk accessory under MacsBug and
|
|
tracing the MacOS SCSI Manager calls it made during image acquisition.
|
|
|
|
However, the protocol is very similar to, though not compatible with,
|
|
the one used by the Apple scanners, therefore, if this backend is ever
|
|
extended to support the other Abaton models (they also made a color
|
|
flatbed scanner), it may be possible to fill in some "missing pieces"
|
|
from the (quite detailed) Apple scanner documentation.

|
|
<H2>DEVICE NAMES</H2><PRE>
|
|
This backend expects device names of the form:
|
|
|
|
<I>special</I>
|
|
|
|
Where <I>special</I> is the path-name for the special device that corresponds
|
|
to a SCSI scanner. For SCSI scanners, the special device name must be a
|
|
generic SCSI device or a symlink to such a device. Under Linux, such a
|
|
device name takes a format such as <I>/dev/sga</I> or <I>/dev/sg0</I>, for example.
|
|
See <B><A HREF="sane-scsi.5.html">sane-scsi(5)</A></B> for details.
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The contents of the <I>abaton.conf</I> file is a list of device names that
|
|
correspond to Abaton scanners. Empty lines and lines starting with a
|
|
hash mark (#) are ignored. See <B><A HREF="sane-scsi.5.html">sane-scsi(5)</A></B> on details of what consti-
|
|
tutes a valid device name.
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/abaton.conf</I>
|
|
The backend configuration file (see also description of
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
<I>/usr/local/lib/sane/libsane-abaton.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-abaton.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
This environment variable specifies the list of directories that
|
|
may contain the configuration file. Under UNIX, the directories
|
|
are separated by a colon (`:'), under OS/2, they are separated
|
|
by a semi-colon (`;'). If this variable is not set, the config-
|
|
uration file is searched in two default directories: first, the
|
|
current working directory (".") and then in
|
|
/usr/local/etc/sane.d. If the value of the environment variable
|
|
ends with the directory separator character, then the default
|
|
directories are searched after the explicitly specified directo-
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
would result in directories "tmp/config", ".", and
|
|
"/usr/local/etc/sane.d" being searched (in this order).
|
|
|
|
<B>SANE_DEBUG_ABATON</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 255 requests all debug output to be printed.
|
|
Smaller levels reduce verbosity.
|
|
|
|
|
|
</PRE>
|
|
<H2>BUGS</H2><PRE>
|
|
There are a few known ones, and definitely some unknown ones.
|
|
|
|
<B>Scan</B> <B>area</B> <B>miscalculations</B>
|
|
For the sake of programmer efficiency, this backend handles all
|
|
measurements in millimetres, and floors (rather than rounds)
|
|
values to avoid possible damage to the scanner mechanism.
|
|
Therefore, it may not be possible to scan to the extreme right
|
|
or bottom edges of the page.
|
|
|
|
<B>Cancelling</B> <B>the</B> <B>scan</B>
|
|
This might not work correctly, or it might abort the frontend.
|
|
The former is more likely than the latter.
|
|
|
|
If you have found something that you think is a bug, please attempt to
|
|
recreate it with the SANE_DEBUG_ABATON environment variable set to 255,
|
|
and send a report detailing the conditions surrounding the bug to
|
|
<I>sane-devel@lists.alioth.debian.org</I>.

This will allow me to add support for other models with reason-

the information returned by the INQUIRY command.

based on the sane-apple backend by Milon Firikis.
