<EM>> No, I have not. Otherwise I would not have uploaded the new
|
|
</EM><BR>
|
|
<EM>> stuff to the CVS server. I am not using the PNM format to
|
|
</EM><BR>
|
|
<EM>> store my images, if I use xsane directly (not as a Gimp
|
|
</EM><BR>
|
|
<EM>> plugin) then I use TIFF.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> I'll check tonight if this shows up on my system as well.
|
|
</EM><BR>
|
|
<P>OK, I did check and you are right, there is something wrong.
|
|
<BR>
|
|
It does show up on my Perfection610, but the Perfection1200
|
|
<BR>
|
|
does fine. Also, when I store as TIFF then everything's fine.
|
|
<BR>
|
|
<P>The effect on the Perfection610 is not a bug, it's a feature :-)
|
|
<BR>
|
|
Some background: This scanner does send the three color channels
|
|
<BR>
|
|
in the order it scans them - there is a shift between the three
|
|
<BR>
|
|
channels. I have to "re-shuffle" these lines to get rid of this
|
|
<BR>
|
|
shift. To get rid of some artifacts at the beginning and the end
|
|
<BR>
|
|
of the scan I have to modify the scan area. This works fine as
|
|
<BR>
|
|
long as there is room to increase the scan area: This is of course
|
|
<BR>
|
|
not possible when you are scanning the whole page.
|
|
<BR>
|
|
<P>I do however not understand why this shows up with the GT-7000
|
|
<BR>
|
|
(If I remember correctly, this is the Perfection636). Do you
|
|
<BR>
|
|
have the SCSI or the USB version?
