Sorry for the late response, but the mail mail was delayed until today.
|
|
<p>
|
|
Since you have read the archive: The problem with the wrong colors is
|
|
related to the
|
|
"bytes_per_line should be 3 * pixels_per_line, but it isn't" problem.
|
|
<p>
|
|
Other users have reported exactly the same misbehaviour (wrong colors) for
|
|
the version that works for you. I am currently trying to collect a list
|
|
of models and FW versions to elaborate the circumstances, under which this
|
|
behaviour is shown.
|
|
<p>
|
|
Thus it would be interesting, which FW version and model code your device has.
|
|
<p>
|
|
Also, there exists an update of the backend on
|
|
<p>
|
|
<a href="ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.280399.tar.gz">ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.280399.tar.gz</a> .
|
|
<p>
|
|
If you like, you can try it and tell me the results. I would be interested,
|
|
if it works for you or if the colors are wrong again.
|
|
<p>
|
|
In any case: I know now where the problem is and can provide a patch, if
|
|
necessary.
|
|
