|
|
<P>Kevin left a number of clues in the code as to what needs to
|
|
<BR>
|
|
be done. Basically, the RGBRouter needs adapting so that it
|
|
<BR>
|
|
passes the R,G and B channels onto sane with the right offsets.
|
|
<BR>
|
|
According to the changelog, this code was already in the snapscan-310
|
|
<BR>
|
|
source. I only hope the offset really is an integer amount of lines.
|
|
<BR>
|
|
<P>Meanwhile, I found that seperating the channels in gimp, offsetting
|
|
<BR>
|
|
red and blue, and recombining them does the trick as well. I'll try
|
|
<BR>
|
|
to script this into gimp, so I can fiddle around with the offsets
|
|
<BR>
|
|
more easily. I'll make the script available if anyone is interested.
|
|
<BR>
