Hi,
<BR>

<BR>
<EM>&gt; I did some work at the microtek2 backend to get my Phantom330CX
</EM><BR>
<EM>&gt; supported. I also corrected compiler warnings and eliminated
</EM><BR>
<EM>&gt; fprintf(stderr, ...) calls.
</EM><BR>
<P>That's fine :-)
<BR>
<P><EM>&gt; The backend works with my Scanner (not
</EM><BR>
<EM>&gt; perfectly but quite well), but I'm not sure if my modifications work
</EM><BR>
<EM>&gt; with other scanner models. I also think my code needs to be checked
</EM><BR>
<EM>&gt; because this is my first exercise in C-programming.
</EM><BR>
<P>Have you talked to the current maintainer of mikrotek2, Bernd
<BR>
Schroeder? He's supposed to be &quot;active&quot;, at least that's what the
<BR>
AUTHORS file says :-)
<BR>
<P><EM>&gt; I will keep working but it's difficult because I get no technical input
</EM><BR>
<EM>&gt; &gt;from Microtek, only old specs from 1997.
</EM><BR>
<P>I know this problem from Mustek ...
<BR>
<P><EM>&gt; In addition I want to remove (model-dependent) some option sliders
</EM><BR>
<EM>&gt; (contrast, brightness, shadow, midtone, highlights) that are not
</EM><BR>
<EM>&gt; supported by the scanner hardware. I think it is senseless to implement
</EM><BR>
<EM>&gt; this functions in the backend by additional code,
</EM><BR>
<P>Depends on how complicated this is. This may be interesting if you do
<BR>
lots of scans e.g. with scanimage and don't want to manipulate every
<BR>
image by hand. On the other hand I'm sure there are command line tools
<BR>
to e.g. increase brightness, too.
<BR>
<P><EM>&gt; let GIMP do this much
</EM><BR>
<EM>&gt; better ...? Can somebody give me a hint how to control the appearance of
</EM><BR>
<EM>&gt; the sliders?
</EM><BR>
<P>That's done by the SANE options (see sane.ps on the SANE website). If
<BR>
you remove the option (or set SANE_CAP_INACTIVE) the slider won't be
<BR>
available anymore.
<BR>
<P><EM>&gt; I think I will do some modifications to the code in the next weeks. What
</EM><BR>
<EM>&gt; do you think, should I provide my actual code for testing?
</EM><BR>
<P>Absolutely. Put it on a website, write down what you changed and
<BR>
announce the code on sane-devel. After some testing, ask the
<BR>
maintainer to include it. If he doesn't have time to do it, we will
<BR>
find another solution.
<BR>
<P>Bye,
<BR>
&nbsp;&nbsp;Henning
