<EM>&gt; this?

<P>After you wrote the same mail to me on 2000-09-24 I had answered this. Didn't
<BR>
you get the answer or didn't my solution work? Here is a copy of my answer:
<BR>
<P>br-x is the bottom right x position. So this value is probably to big. The
<BR>
problem is that scanimage first calculates its x (width) value by doing br-x
<BR>
- tl-x.
<BR>
&nbsp;
<BR>
Then it gets the new value for top right x tl-x (-l 5) but doesn't
<BR>
recalculate it's width. So the old width is used (full scan area) which is
<BR>
too wide.
<BR>
&nbsp;
<BR>
<EM>&gt; Hope you know a workaround for this problem or any other solution.
</EM><BR>
&nbsp;
<BR>
Add a width parameter (-x), e.g.:
<BR>
&nbsp;
<BR>
scanimage -d mustek:/dev/scanner -l 5 -x 210.9 --contrast 0 --resolution
<BR>
201 --mode Gray &gt;/tmp/out2.pnm
<BR>
&nbsp;
<BR>
Bye,
<BR>
