Hello,,
|
|
<BR>
|
|
<P>H> blue, green or red. Well not just shifted, that I could correct ...
|
|
<BR>
|
|
<P><EM>> > The most remarkeable thing about it is, that it is reproduceable and the
|
|
</EM><BR>
|
|
<EM>> > type of the wrong color depends on the used resolution. So scanning at
|
|
</EM><BR>
|
|
<EM>> > 120 dpi ist a blue like image without any red scanning with 125 dpi becomes
|
|
</EM><BR>
|
|
<EM>> > more and more green ...
|
|
</EM><BR>
|
|
<EM>> That's the "standard" line-distance correction problem. Could you please send a
|
|
</EM><BR>
|
|
<EM>> debug log to me, I need to know the firmware version and some further
|
|
</EM><BR>
|
|
<EM>> details of your scanner.
|
|
</EM><BR>
|
|
<EM>> SANE_DEBUG_MUSTEK=5 scanimage -L 2>debug.log
|
|
</EM><BR>
|
|
<P>ok, did it. I'll attach the log at the end of the message.
|
|
<BR>
|
|
Firmware is 1.06
|
|
<BR>
|
|
<P><EM>> > Additionally I get some "bad lines" in the pictures, they repeat in a constant
|
|
</EM><BR>
|
|
<EM>> > frequent all over the image. If the image is dark, those lines (1-3 pixel
|
|
</EM><BR>
|
|
<EM>> > broad)
|
|
</EM><BR>
|
|
<EM>> > are bright and visa versa.
|
|
</EM><BR>
|
|
<EM>> These are at the place where the scanner starts a new block ob data. If you
|
|
</EM><BR>
|
|
<EM>> change the buffersize (option buffersize in mustek.conf) the distance
|
|
</EM><BR>
|
|
<EM>> between these lines should change, too.
|
|
</EM><BR>
|
|
<P>Hm well this is correct. But how do I fix it
|
|
<BR>
|
|
<P><EM>> > Since there are no options in the mustek.conf I tried out so change almost
|
|
</EM><BR>
|
|
<EM>> > everything
|
|
</EM><BR>
|
|
<EM>> > I can.
|
|
</EM><BR>
|
|
<EM>> In mustek.conf, option linedistance-fix should be removed or commented out
|
|
</EM><BR>
|
|
<EM>> if it's there.
|
|
</EM><BR>
|
|
<P>It is commented out. Neither having it aktive or commented out it does not change
|
|
<BR>
|
|
the
|
|
<BR>
|
|
behavior :-(
|
|
<BR>
|
|
<P><EM>> The problem is probabaly easy to solve in mustek.c when I know the firmware
|
|
</EM><BR>
|
|
<EM>> version. I had one more report about a similar problem since SANE 1.0.3.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> > The problem is the same with different types of images, different
|
|
</EM><BR>
|
|
<EM>> > kernels (2.2.14 - 2.2.17)
|
|
</EM><BR>
|
|
<EM>> > and I even plugged a Adaptec 2490 in. All the same error.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<P>To correct my type error: 2940 :-)
|
|
<BR>
|
|
<P><EM>>
|
|
</EM><BR>
|
|
<EM>> The error results from different methods to compensate fort the line shift
|
|
</EM><BR>
|
|
<EM>> of the three color CCD lines. Some scanners do this line-distance correction
|
|
</EM><BR>
|
|
<EM>> internally, for some this must be done in the backend. So the backend must
|
|
</EM><BR>
|
|
<EM>> know for which firmware version it should do the correction and for which
|
|
</EM><BR>
|
|
<EM>> it's not necessary.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<P>ok, I got that. I am really glad you help me. I havent found a single word to that
|
|
<BR>
|
|
problems in the documentation or on the websites. Maybe I havent
|
|
<BR>
|
|
looked close enough.
|
|
<BR>
|
|
<P><EM>> No, that's OK. They are identical. Mustek's scanner names are quite "funny".
|
|
</EM><BR>
|
|
<EM>> I have two 1200 SPs, both are labeled MFS-12000SP on the back. One is labeled
|
|
</EM><BR>
|
|
<EM>> "MFS-12000SP" on the front, the other one is a "1200 SP" (without MFS). If
|
|
</EM><BR>
|
|
<EM>> you ask the firmware for their name, it's "MSF-12000SP" (not MFS!). Ah and
|
|
</EM><BR>
|
|
<EM>> yes, a Paragon 1200 SP III would be a total different scanner despite its
|
|
</EM><BR>
|
|
<EM>> name.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<P>Yep, that's excactly what I heard about it!
|
|
<BR>
|
|
<P><EM>> Check if "net" is in dll.conf. You can add the name of the backend+device to
|
|
</EM><BR>
|
|
<EM>> xsane/xscanimage:
|
|
</EM><BR>
|
|
<EM>> xsane mustek:/dev/scanner
|
|
</EM><BR>
|
|
<P>Net was configured. I just messed up the "device-parameter" from scanimage and
|
|
<BR>
|
|
xscanimage!
|
|
<BR>
|
|
scanimage -dnet:computer:mustek:/dev/scanner
|
|
<BR>
|
|
xscanimage net:computer:mustek:/dev/scanner
|
|
<BR>
|
|
It works fine via network even with the frontend now.
|
|
<BR>
|
|
Ok, here comes the logfile, in hope you can help me to fix the last color -
|
|
<BR>
|
|
problem.
|
|
<BR>
|
|
<P>Thanks a thousand time for your efforts !
