Hello,
unpaper version 1.1 has been released. unpaper is a tool for
post-processing scanned book pages.
Some new features at a glance:
- Combine single-page scans to 2-page layout output.
- Resize to specific sheet sizes ('a4', 'letter', ...), zoom, stretch.
- Optimized speed of the auto-rotatio

You can set the output sheet to a specific size with the desired dpi
resolution, e.g.
--dpi 300 --size a4
In that

--border-align top
--border-margin 1.75cm' to get nicer results.)

Hello SANE people,
there had been very valuable feedback from this list after I had released the

unpaper (http://unpaper.berlios.de/), so I would like to let you know about a

Hello sane people,
I have started using saned and network-scanning instead of connecting the
scanner/printer locally
via USB.
Unfortunately, the maximum size to scan is 210mm x 293mm for black&white scans,
which is almost a
full-sized A4 image (210mm x 297mm). Attempts to scan larger sizes str
Hello Andi,
nice work. Just to mention: when I run ScanPage (with the server-name and
options adopted to my
setup), there seems to be a problem with device.close(). The first time, the
image gets scanned
correctly and is shown in the JFrame which pops up, but a second run fails with:

Also another problem I have with the MFC3420C (see

What program are you using? What OS? Command-line/GUI?

Hello,
unpaper removes black edges and other photocopy artefacts from scanned
images. It also deskews book pages (auto-rotates them to a straight
alignment), and centers them on the sheet.
Old photocopies can become well-readable PDFs again.

Are you using 1-bit-per-pixel input or output files (i.e. .pbm, not
.pgm)? The only place where I would ad-hoc suspect an endianess issue is
when the single bits are accessed during conversion from/to 1-bit images...

Hello,
an updated version of unpaper is available at:
http://download.berlios.de/unpaper/unpaper-1_0_1.tgz
This hopefully fixes problems that occurred on some platforms with
optimized binary executables, and some other minor issues.
