<H2>NAME</H2><PRE>
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.
</PRE>
<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>.

<B>Finish</B> <B>reverse-engineering</B> <B>the</B> <B>MacOS</B> <B>driver</B>
This will allow me to add support for other models with reason-
able confidence that it will work, as well as to fully exploit
the information returned by the INQUIRY command.
