Hey guys,

So I have looked at Michael's code and tested it with my scanner. Good news is this works and is nice and neat (you have saved me a shitty job there Michael).

I think it is probably time we committed this to the SANE repository so we should stop developing the version in Michaels patch and look at making sure it is up to standard to go into the repo.

@Michael: do you mind if I add those patches to the project website?

@Stef: could you advise on the next steps to adding this patch to the SANE repository?

Thanks very much Michael,

Hello Chris, hello everybody else,
I am new here. Thanks to your work, Chris and your sources (
http://sites.google.com/site/bez625/updates-1/update120410  ) I can use
an Optibook 3600 under Sane for scanning in some pics for my lectures.
You can find my current diffs in
cb-pobook-initial.diff is how I transposed Chris' work to Sane git
3de5c8738 (Mon Nov 8 18:01:29 2010 +0100). shifted-shading.diff contains
my own work, a rather strange shading function in which the color matrix
is rotated every 256 values. I found that by writing less than 3 color
channels. In the same directory you can find some test scans at
different dpi. The 600dpi one is a bit marginal as we do not yet use
offset and gain calibration. 1200dpi scans do not work yet.
For everybody who is willing to test the backend I have also put the
Ubuntu packages up which I use.
