Hi Stef
in order to notice tne lines let me describe them a little more.
the green lines are very very light, mostly seen in white/clear zones
of the image, not on dark ones. and are always on the left side of the
image, at about 1 cm from the left margin. they go from top to bottom
of the scan,
At least this is how i see them :-P (hope is not only a paranoia of
mine :-D )
i've enabled debugging as instructed and created 5 new scans with the
command posted. Some of the scans, (number 2 and 4) are mostly white,
in order to see the issue in more detail.
Hello,
beside log file, there are also other *.pnm files created during
calibration (in the working directory where the scanimage command is
ran). Can you send them ? What I suspect is that there could be some
color pattern (some kind of notch) in a area expected to be white. So
shading calibration is wrong and leads to the artifact on the scanned
picture.
Regards,
Stef
