Title:
gscan2pdf distorts image with scanimage.pl frontend, but works with
I got the same problem with skewed scans using libsane-perl when running
gscan2pdf directly from source. I couldn't use scanimage with my scanner
"Fujitsu fi-4120C2" because the scanner wasn't found. I found a solution
to add the scanner to scanimage:
Create the file "40-libsane.rules", put in
Where's the option for this?
In Edit/Preferences.
Ha... starred right at it and didn't see it. Thanks. And, yes, it
worked just fine with scanimage picked.
As far as I'm concerned, it's fixed :) I'm a happy camper... well, make that a
happy scanner.
Thanks for the hint.
If you want to
I'm also now getting distortion with gscan2pdf. Not sure about the
scanimage.pl front-end bit. Where's the option for this?
Here's what I do know:
Everything worked great with Ubuntu v8.10. Last week, I scanned in a
480 page book and it was great (awesome program by the way). I just

Scanner in question is an HP LaserJet 3200 (all in one), locally
attached via USB.
I have been using gscan2pdf infrequently for years without any issue. Two
days ago, without any changes in configuration, my scans appear skewed.
This is true for both 0.9.27 from Jaunty and 0.9.29 from the Launchpad.
I narrowed it down to the x-perl frontends.
The following frontends are

I can't reproduce this and I therefore don't know how to debug it.
FWIW, I am using Intrepid on i386 with an HP Officejet 5510

Right. I didn't have this with intrepid, only after I upgraded to
jaunty. Since this is unlikely to be fixed for the jaunty release, let's
continue after the release, when I will have more time to do test scans.
Ping me then, please.

Can you do a quick check on the Lenny machine to see if the problem is
related to the net backend?

That scanadf and scanimage work fine you demonstrated before, but if you
could check the output from scanimage.pl frontend when the scanner is
directly attached to the machine running Jaunty, we could see if the
problem is related to the net backend.

The scanimage.pl and scanadf.pl commands also result in good scans from
the command line on the jaunty computer with scanner attached directly
to it.

On closer look, no they don't. scanadf.pl produces a slightly distorted
image from the command line when scanner is attached directly. Also over
the net.
Summary of results:
Works: scanner is attached to either machine, accessed locally or over
the net, using scanadf or scanimage.
Doesn't work:
Thanks for clarifying. I'll try and work out how I can debug the problem
- I don't have a second machine.

According to ImageMagick's identify, the images have been through
unpaper. Whilst unpaper almost certainly has nothing to do with the
problem, it is an extra variable.
They are 8-bit images. Do you get the same distortion with 1-bit scans?
What about smaller scans? If you scan, say, just a
The images I've uploaded were scanned with gscan2pdf, which I've
configured to run unpaper. If I scan things from the command line,
there's still distortion, so unpaper is not relevant.
scanadf doesn't give me a setting for bit depth. It gives me --mode,
with options color, gray, and lineart. No

Grayscale is still 8-bit. Lineart would be 1-bit. Can you confirm that
lineart gives you the distortion?
Can you also try color or grayscale for a smaller scan?

scanadf.pl with lineart still distorts. A top-left partial scan (lineart
or color) doesn't distort, but since the distortion happens in bands,
that's not really conclusive. Since using scanadf works for me, I'm not
really motivated doing a few more dozen scans and inspecting them for
distortion,
This is the first time I have heard of a problem with the scanimage.pl
frontend.
Just for your info - the scanimage.pl and scanadf.pl frontends are the
scanimage and scanadf frontends, rewritten in Perl, using the libsane-
perl Perl bindings.
Please confirm that the scanadf.pl frontend also

In case it matters: the scanner is not physically attached to the
