Hi!
|
|
<BR>
|
|
<P>[Grega Bremec]
|
|
<BR>
|
|
<EM>> I already thought it's not going to work, because after I installed
|
|
</EM><BR>
|
|
<EM>> it, the symptoms were just the same as before: the sounds of the rotor
|
|
</EM><BR>
|
|
<EM>> moving were coming out of the scanner, but the head never went
|
|
</EM><BR>
|
|
<EM>> anywhere (although everything was happening much faster than in the
|
|
</EM><BR>
|
|
<EM>> 8-devel version). Then, after a good night's sleep, I took another
|
|
</EM><BR>
|
|
<EM>> look at the test session log transcript (with SANE_DEBUG_MUSTEK_PP set
|
|
</EM><BR>
|
|
<EM>> to 128), and I noticed this line saying
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> [mustek_pp] attach: use600 is `no'
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> which gave me a good reason to think everything over. I looked at the
|
|
</EM><BR>
|
|
<EM>> manpage (doh!), and of course, it was all there.
|
|
</EM><BR>
|
|
<P>Yes, maybe I should have pointed this out... there are scanners using
|
|
<BR>
|
|
the same hardware but scan at 300 dpi, so the backend can't determine
|
|
<BR>
|
|
which your are using, unless you specify it.
|
|
<BR>
|
|
<P><EM>>
|
|
</EM><BR>
|
|
<EM>> Now I can report to you that grayscale works quite well, although I
|
|
</EM><BR>
|
|
<EM>> still have to test it with xsane to see how much post-processing can
|
|
</EM><BR>
|
|
<EM>> improve the scan results (the raw pnm output seems a bit on the dark
|
|
</EM><BR>
|
|
<EM>> side), as well as lineart mode (which one would almost expect, since
|
|
</EM><BR>
|
|
<EM>> it only seems to be a small step away from grayscale scanning).
|
|
</EM><BR>
|
|
<P>The 600 dpi scanner support hardware gamma correction & stuff - but the
|
|
<BR>
|
|
backend doesn't (yet). This will change in the future.
|
|
<BR>
|
|
<P><EM>> Let me express my gratitude again, and please, if there is anything I
|
|
</EM><BR>
|
|
<EM>> can do to help you develop a working colour-scan, do let me know.
|
|
</EM><BR>
|
|
<P>I'll start working on the color scans not before next week :-( from
|
|
<BR>
|
|
tuesday on I'll be at unitversity till friday (without my scanner)
|
|
<BR>
|
|
<P><EM>>
|
|
</EM><BR>
|
|
<EM>> As a side note - what is this supposed to mean (I suppose it's an
|
|
</EM><BR>
|
|
<EM>> obsolete checkpoint now :-))?
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> [mustek_pp] init_options(v1.0.9-devel): line 2701: debug exception
|
|
</EM><BR>
|
|
<EM>> [mustek_pp] ASSERT((dev->asic_id == 0xA8) || ((dev->asic_id == 0xA5) \
|
|
</EM><BR>
|
|
<EM>> && (dev->ccd_type == 0))) failed
|
|
</EM><BR>
|
|
<EM>> [mustek_pp] expect disaster...
|
|
</EM><BR>
|
|
If all feedbacks are this positive, it will surely be removed in the
|
|
<BR>
|
|
next version :)
