Hi,
<BR>
<P>Success! I downloaded a fresh copy of sane-1.0.3 and the latest snapscan
<BR>
drivers, and dropped them in to sane-1.0.3/backend. First I compiled them
<BR>
as-is, and linked xscanimage as a gimp plug-in, and was able to preview in
<BR>
color, and scan in color up to 300 dpi. Next, I tried changing line 90 in
<BR>
the snapscan.h file
<BR>
from {&quot;FlatbedScanner_4&quot;, VUEGO310S}
<BR>
to {&quot;FlatbedScanner_4&quot;, VUEGO610S},
<BR>
<P>since as I mentioned, the scanner is really 600 DPI even though the Vendor
<BR>
string is &quot;FlatbedScanner_4&quot;.
<BR>
Recompiled and installed, and the scanner now scans up to 600 DPI!
<BR>
<P>Interesting to note that the dropdown menu in xscanimage for resolution has
<BR>
choices up to 9600 DPI, but at higher resolutions, xscanimage hangs, and
<BR>
uses 90% cpu. Actually, at 1200 DPI, I got one scan, but in the horizontal
<BR>
dimension, the image was scrunched up on the left and there were Red Green
<BR>
and Blue stripes in a black field on the right side.
<BR>
<P>Anyway, it looks great so far, thanks!
<BR>
<P>Next issue is to get 30 bit color depth. I have not tried to compile Xsane
<BR>
with the new backend yet. What are my chances there?
<BR>

<EM>&gt; &gt; I have similar problems to what is reported here. The scanner I have is
</EM><BR>
<EM>&gt; &gt; called
</EM><BR>
<EM>&gt; &gt; AcerScan (Prisa) 610ST It is a SCSI model with a built-in transparency
</EM><BR>
<EM>&gt; &gt; module.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I will put a new version here:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; <A HREF="http://download.sourceforge.net/snapscan">http://download.sourceforge.net/snapscan</A>
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; something like snapscan-30102000.tar.gz
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; It adds auto preview mode (color or greyscale or... depending on
</EM><BR>
<EM>&gt; scanning mode) thanks to Laurent Grawet.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Someone has reported that the AGFA Snapscan 310 SCSI works well with
</EM><BR>
<EM>&gt; this new version.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; It has been modified to support VUEGO310S, VUEGO610S and
</EM><BR>
<EM>&gt; SNAPSCAN1236S. So it should correct your problem. I don't know if
</EM><BR>
<EM>&gt; FlatbedScanner_4 is really used by some VUEGO310S or if it is only
</EM><BR>
<EM>&gt; with VUEGOS610S (that would be annoying to have 2 different models
</EM><BR>
<EM>&gt; with the same string...)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I would really like to have some feedback for those versions. At this
</EM><BR>
<EM>&gt; time it has only been reported to work with Acer 300f and Agfa 310.
