[Bug 358970] Re: gscan2pdf distorts image with scanimage.pl frontend, but works with scanadf frontend

[Fixerdave]

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 to Ubuntu v9.10 and it stopped working.

Details:
Scanner in question is an HP LaserJet 3200 (all in one), locally attached via USB.  Another scanner, an Epson v300 with the extra drivers, did scan in just fine with gscan2pdf, so it's something specific to the HP.  (there is another bug with the Epson: Bug #424249, but that's a different story).

The HP scanner works fine with Xsane, so the scanner does actually work.

The distortions are horizontal banding and repeating.  The very top of
the page is fine, but then bits just get repeated and shuffled
horizontally as well.  The size of the repeated areas seem to be
dependent on resolution; higher res, giving smaller areas repeated more
often.

I do have a work-around... I can scan to jpg pages via xsane and then
import those images to gscan2pdf, which (despite Bug #424249) I can save
as a PDF just fine.  (I'll add this part as a comment on the that bug
too).

Again, gscan2pdf is a great program.  Even without the ability to scan
from my particular scanner, I'm still using it to make the PDFs.  I hope
this information helps you make it even better.
