<EM>&gt; Hi !
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I've now full access to my scanner (thanks), moreover via xsane, as a gimp
</EM><BR>
<EM>&gt; plugin :-)))
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Perhaps there are infographists on this lists, so I have a question for them...
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Please have a look at www.calvo-france.com/cacharel.jpg and tell me :
</EM><BR>
<EM>&gt; - why do I obtain these dark spots (inside the red ellipse) when scanning
</EM><BR>
<EM>&gt; - with the twain driver (under win, so), I had an option called &quot;d<EFBFBD>moirer&quot; in
</EM><BR>
<EM>&gt; french, that allowed me to remove these spots when scanning. Sane doesn't have
</EM><BR>
<EM>&gt; it (I'm not sure about that).
</EM><BR>
<EM>&gt; - if i cannot do without it, how can i remove them with gimp ?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Thanks again for your help !
</EM><BR>
<EM>&gt;

Hi Arnaud,
<BR>
<P>the spots you see are caused by a bad scanresolution.
<BR>
If you would scan the image with the resolution it was printed
<BR>
you would not get these spots.
<BR>
<P>There is something like demoirer in the gimp.
<BR>
I think it is called despeckle there.
<BR>
<P>Bye
<BR>
Oliver
