small area scanned - Githubissues

The scanned area of my document is too small. I've only 1/8 of my whole page scanned (7,7*9,5cm approx).

Regarding list_all.py: Please keep in mind all my code is for python2.7, and ArchLinux uses by default Python 3. So the correct command would be:

$ python2.7 ./list_all.py

That's weird : scanimage -L reports only one device, but Paperwork obviously get 2 :

[Noname Hercules Dualpix Exchange] -> [v4l:/dev/video0]
[Canon CanoScan N670U/N676U/LiDE20] -> [plustek:libusb:005:012]

Also, there is an uncatched exception when it tries to get the available resolutions of each one. I assume it's normal for the first one. For the second one, it's a known bug, and it has already been fixed in the branch 'unstable' (see #230). It's probably why your scan is cropped too small.

Please try the branch 'unstable' and tell me if it works better for you:

$ git clone https://github.com/jflesch/paperwork.git
$ cd paperwork
# (system-wide installation)
$ sudo python ./setup.py install

Sorry for the output of "scanimage -L", only one of my 2 devices were connected.

Hm, I have a felling you installed Paperwork and all its dependencies for Python 3 instead Python 2.7. I think you must also call "pip2.7" instead of "pip" to install everything for python 2.7.

Installed python2-pip, and the pip-2.7 command is ok:

sudo pip-2.7 install "git+git://github.com/jflesch/paperwork.git#egg=paperwork"

But same problem (output without gtk-warnings) :

Cleaning up...

Arghh. I'm so impatient to work with paperwork since I've seen the article on linuxfr.org...

Hm, did you try the branch 'unstable' as I suggested ? As I said, your settings dialog's bug is probably already fixed, and this is probably what caused the wrong cropping of your scans.

    $ git clone https://github.com/jflesch/paperwork.git
    $ cd paperwork
    $ sudo python ./setup.py install

ERROR paperwork.backend.img.page Reason: Dictionary for language 'fr' could not be found

You're missing the french dictionnary for python-enchant. It will make orientation detection less reliable. I think install myspell-fr[-gut] will solve that.

~~Woops, I meant:~~

    $ git clone https://github.com/jflesch/paperwork.git
    $ cd paperwork
    $ git checkout unstable
    $ sudo python ./setup.py install

Sorry.

Argh, I forgot a few things required for the branch 'unstable':

$ pacman -S zlib-dev libblas-dev libatlas-dev liblapack-dev gcc-gfortran g++
$ sudo pip-2.7 install numpy scikit-learn
$ git clone https://github.com/jflesch/paperwork.git
$ cd paperwork
$ git checkout unstable
$ sudo python-2.7 ./setup.py install

You may have to adjust the package list for pacman. I don't know the exact package names for ArchLinux.

I now have new features with these commands, but no ability to define a larger zone to scan.

Did you reopen the settings dialog and redo the scanner calibration before scanning ? If you don't, the old (crappy) settings will still be used.

By the way, when you do the scanner calibration in the settings window, is the scan correct ? Does it display the whole content of your scanner without cutting anything ?

No, the scan resulting of calibration isn't correct : only the upper left corner is scanned.

Ok, this is not at all the problem I had in mind :/

Can you retry running

$ python2.7 ./list_all.py

please ?

Since you have Paperwork obviously running, it shouldn't complain about missing modules.

cd ~/pyinsane python2.7 ./list_all.py

Ok, the problem is clearly here. Paperwork doesn't set these values. I'll try to fix it by the end of the week.

Fixed by a3efa17252764dcc92e830620b2cb18a58a1ec29 on the branch 'unstable'. Sorry for the delay
