ng on the sane project!
I scanned the same photo I had done before. If anyone is interested in seeing
the before and
after and requests it, I will post the new one on the web as well.

Gerhard:
I'll checkout the CVS version and let you know how it does.
I am curious as to what the problem was, though, that was fixed.

I've put an example at my family website at:
http://www.hopelesscase.com:81/pictures/sane/page1.jpg
I scanned it at 600 dpi. I of course did no post-processing to this (beyond
converting it to
jpeg). A gamma

I had sent this during the down period.
Here it is again.
I have done some more experimenting with using the GIMP's destriping filter,
which seems to work
very nicely. I'd still like to understand why it happens though.

All:
I think I've basically answered my own question,"How should you attempt to
deduce a correct gamma
correction
value for your scanner with sane?"
The procedure is this:
- open a graphics program like the gimp and make some blocks of solid color
(gray scale)
- I suggest hitting the followin

I have been using Sane for about two months now with a CanoScan LiDE 80 and
getting great results.
I have been wondering, however, about how best to enhance my images after
scanning.
They have been coming out fairly dark with no corrections. I have dealt with
this in two ways.

Thanks! I would be interested to see your script.
What's the exact model number on your epson?

That sounds perfect!
As for high volume, I don't need that high. If I had a good shot at scanning
20 pages at a time,
I'd be willing to spend $300 to get that capability.
Thanks for the steer.
So, how does sane-epson handle document feeding? If I invoke scanimage, would
it feed one page,

Can anyone recommend a scanner that works with sane and has a document feeder?
Assuming there is such a scanner...
I would like to be able to invoke scanimage so that it loads a new page, scans
it, and exits.
With that, it is a simple matter to write scripts to handle the naming of each

I was just curious if specifying a contrast argument to the backend is
different from doing a
default scan and adjusting the contrast in the gimp after the scan.
I would imagine that it does mean something different in that you would be
setting the contrast
before the A/D step in the scanner if

I am using sane front end 1.0.11 and backend 1.0.13 on slackware linux 9.0.
I configured /etc/sane.d/sane.plustek.conf thusly:
[usb] 0x4a9 0x220e

When I ran scanimage -L, all of the tests passed.
When I try to run scanimage > image.pnm, I can see the scanner being
