Hi,
|
|
<BR>
|
|
<P><EM>> > I've put a first version of my patch for transparency support in the snapscan
|
|
</EM><BR>
|
|
<EM>> > backend on my homepage (<A HREF="http://www.ginko.de/user/oschwartz/snapscan">http://www.ginko.de/user/oschwartz/snapscan</A>).
|
|
</EM><BR>
|
|
<EM>> >
|
|
</EM><BR>
|
|
<EM>> > Up to now I have only tested it with an Acer ScanPrisa 620UT.
|
|
</EM><BR>
|
|
<EM>> >
|
|
</EM><BR>
|
|
<EM>> > The patch is for sane-1.0.2. It does not work with previous versions.
|
|
</EM><BR>
|
|
<EM>> >
|
|
</EM><BR>
|
|
<EM>> > If you have a Snapscan or Acer Prisa scanner with transparency unit please try
|
|
</EM><BR>
|
|
<EM>> > it and tell me whether it works for you.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> it runs! Thank you very much for your work.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Only the following appeared:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> On your homepage in the "installation instructions" under "5." should
|
|
</EM><BR>
|
|
<EM>> only be the instruction "make", under "6." "make install", without dot
|
|
</EM><BR>
|
|
<EM>> and slash. This way my system is working correctly.
|
|
</EM><BR>
|
|
<P>You're right. I've changed it.
|
|
<BR>
|
|
<P><EM>> I copied "find-scanner" manually, because "make install" and
|
|
</EM><BR>
|
|
<EM>> "tools" haven't been installed.
|
|
</EM><BR>
|
|
<P>That's true. However, it's a general sane problem. I don't know why find-scanner
|
|
<BR>
|
|
is not installed by "make install" (anyone?).
|
|
<BR>
|
|
<P><EM>> Version 1.0.2 don't overwrite existing files in /usr/local/etc/sane.d
|
|
</EM><BR>
|
|
<EM>> and /usr/local/lib/sane. I searched for it a long time, at least
|
|
</EM><BR>
|
|
<EM>> found it and then deleted it manually.
|
|
</EM><BR>
|
|
<P>Hm... It should leave old configuration files in /usr/local/etc/sane.d but
|
|
<BR>
|
|
overwrite binaries in /usr/local/lib/sane. The only reasons I can imagine why
|
|
<BR>
|
|
it didn't work for you is that you had sane 1.0.1 installed. In this case some
|
|
<BR>
|
|
links in /usr/local/lib/sane are not replaced.
|
|
<BR>
|
|
<P><EM>> The scan looks very fine.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Finally I have three wishes:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> The scanarea can be 21,5 x 29 cm.
|
|
</EM><BR>
|
|
<P>Are you sure? I found an electronic version of a Snapscan 300 / 600 manual which
|
|
<BR>
|
|
specifies 203 x 254 mm for transparency mode. I'll add support for
|
|
<BR>
|
|
model-dependent max. scan areas in the next version of the patch.
|
|
<BR>
|
|
<P><EM>> A switch that allows me to choice between negative and positive scan.
|
|
</EM><BR>
|
|
<P>You should use xsane. It already has a "negative" switch.
|
|
<BR>
|
|
<P><EM>> And a little faster scan only by 600 dpi with maximal scan-area in mode
|
|
</EM><BR>
|
|
<EM>> flatbed. A scan with this resolution was running 45 minutes before
|
|
</EM><BR>
|
|
<EM>> xscanimage disapeared suddenly, although only half of the image was
|
|
</EM><BR>
|
|
<EM>> scanned.
|
|
</EM><BR>
|
|
|
|
<BR>
|
|
Hm again... My scanner works fine with this resolution. Is this a new
|
|
<BR>
|
|
behaviour after applying the patch? Does anybody else have this problem with a
|
|
<BR>
|
|
SnapScan 600? What kind of SCSI-adapter are you using?
|
|
<BR>
|
|
<P>Oliver
|
|
<BR>
