chrys87 / ocrdesktop Goto Github PK

Hello all,

It seems the Tesseract data directory is not the same between Debian and Arch so this time ocrdesktop can't find the data directory.

I'll propose a patch to fix that.

Best regards.

Hello,
on latest ARch Linux, probably after upgrade to Python 3.10, the ap does not work.
I get this:

Traceback (most recent call last):
File "/usr/bin/ocrdesktop", line 23, in
from tesserwrap import tesseract
File "/usr/lib/python3.10/site-packages/tesserwrap/init.py", line 1, in

self._handle = _dlopen(self._name, mode)
OSError: /usr/lib/python3.10/site-packages/libtesserwrap.so: cannot open shared object file: No such file or directory

However, the python-tesserwrap package is installed, I compiled it against the latest Python.

Please provide a setup.py installation script using either distutils or
setuptools to ease the installation in development scenarios (virtualenv) and
for packaging.

Thanks

Tested this on ArchLinux with kde Plasma 5.27.6, wayland session.
OCRDesktop does not work under Wayland.

Steps to reproduce:

1. log in to a Wayland session.
2. open a terminal and try the command: "ocrdesktop"
3. the command will throw an error that I can't copy paste for some reason, but you'll get it none the less.

Expected results: OCRDesktop should work under Wayland as well, giving the user more flexibility of choice when it comes to display server.

Actual results: the program does not work under Wayland at all.

OCR desktop provides a gui interface that with a number of options. It generates a list of the rectangles of each word, which could potentially be used to facilitate word highlighting for the screen reader. My goal is to allow a screenshot to be taken similar to gnome-screenshot area selection and still know the position of every word.

some options are:

• Add an option with -f to make OCR desktop search the entire screen for the partial area screenshot that it was passed -- probably, something similar would be necessary to find the position of text copied by the user so it could be highlighted as it is read even though it was accessible to begin with.
• Patch gnome-screenshot to print the position of the screenshot and patch OCR desktop to accept that as an option with -f
• Rewrite this file in python and include it in ocrdesktop: https://gitlab.gnome.org/GNOME/gnome-screenshot/-/blob/master/src/screenshot-area-selection.c -- this would allow us to define an area for repeated screen shots if desired

Does one of these seam like the most practical?

Please bear in mind that I am a high school student with mediocre time management skills. Also considered that we are discussing libraries that I know very little about.

Arch Linux, Ocrdesktop from git (AUR package), Tesseract 4.0.0.
When running just ocrdesktop I get this:

Hello all,

When you try to run the ocrdesktop script like this:
./ocridesktop

You will obtain the following error:
bash: ./ocrdesktop: /bin/python3: bad interpreter: No such file or directory

On Debian, the python3 binary is on "/usr/bin/python3". I assume it's the same on Arch, can you confirm this to me? If yes, I could send you a pull request to fix that or you could do that yourself as the change looks easy to do..

Best regards.
