Title:
gscan2pdf distorts image with scanimage.pl frontend, but works with
scan
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 the

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.

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
upgraded
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 av
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.

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

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, so
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?

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 d
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 200x20
Thanks for clarifying. I'll try and work out how I can debug the problem

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:
Also works fine with scanadf and scanimage on the command line when
scanner is attached directly to machine running jaunty.

I don't know if this is specific to the model of the scanner.
In case it matters: the scanner is not physically attached to the

Just for your info - the scanimage.pl and scanadf.pl frontends are the
