<P>
On Sun, Sep 10, 2000 at 12:55:48AM +0200, you (Jochen Eisinger &lt;<A HREF="mailto:jochen.eisinger@gno.de?Subject=Re:%20new%20mustek_pp%20backend%20version&In-Reply-To=&lt;20000910114356.B23694@lunik&gt;">jochen.eisinger@gno.de</A>&gt;),
<BR>
have somehow managed to commit the following:
<BR>
<EM>&gt; Hi!
</EM><BR>
<P>Hi, Jochen, nice to see you in action again :-)
<BR>
<P><EM>&gt; I put version 0.9-devel of the mustek_pp backend on my page
</EM><BR>
<EM>&gt; (<A HREF="http://home.germany.net/freestyle/sane/">http://home.germany.net/freestyle/sane/</A>).
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; new features:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * 600 dpi grayscale scans on ASIC 1015/CCD 01 (05?) scanners
</EM><BR>
<EM>&gt; * corrected scan area for 300 dpi scanners
</EM><BR>
<EM>&gt; * some bugfixes / some new bugs
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; depending on the feedback I get, I'll commit this version to CVS in a
</EM><BR>
<EM>&gt; few days
</EM><BR>
<P>The feedback is positive, at least as far as the ScanExpress 1200 ED
<BR>
Plus model is concerned. Jochen, you are a czar! :-)))
<BR>
<P>I already thought it's not going to work, because after I installed
<BR>
it, the symptoms were just the same as before: the sounds of the rotor
<BR>
moving were coming out of the scanner, but the head never went
<BR>
anywhere (although everything was happening much faster than in the
<BR>
8-devel version). Then, after a good night's sleep, I took another
<BR>
look at the test session log transcript (with SANE_DEBUG_MUSTEK_PP set
<BR>
to 128), and I noticed this line saying
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;[mustek_pp] attach: use600 is `no'
<BR>
<P>which gave me a good reason to think everything over. I looked at the
<BR>
manpage (doh!), and of course, it was all there.
<BR>
<P>Now I can report to you that grayscale works quite well, although I
<BR>
still have to test it with xsane to see how much post-processing can
<BR>
improve the scan results (the raw pnm output seems a bit on the dark
<BR>
side), as well as lineart mode (which one would almost expect, since
<BR>
it only seems to be a small step away from grayscale scanning).
<BR>
<P>I attached the output of scanimage -T and my mustek_pp.conf just to
<BR>
let you see how things were going on my scanner from the first hand.
<BR>
<P>Let me express my gratitude again, and please, if there is anything I
<BR>
can do to help you develop a working colour-scan, do let me know.
<BR>
<P>As a side note - what is this supposed to mean (I suppose it's an
<BR>
obsolete checkpoint now :-))?
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;[mustek_pp] init_options(v1.0.9-devel): line 2701: debug exception
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;[mustek_pp] ASSERT((dev-&gt;asic_id == 0xA8) || ((dev-&gt;asic_id == 0xA5) \
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&amp;&amp; (dev-&gt;ccd_type == 0))) failed
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;[mustek_pp] expect disaster...
<BR>
<P>Cheers,
<BR>
<P><PRE>
