Thanks for the feedback. I'll hopefully get around to updating the documentation soon. In the meantime:

Added the external versions that I've used locally to the README.

Hello. I am newbie in Python, could you tell me how to install all of these for Python ? For instance, I have tried:

C:\Program Files\Python36>pip install --upgrade poppler
Collecting poppler
  Could not find a version that satisfies the requirement poppler (from versions: )
No matching distribution found for poppler
You are using pip version 18.1, however version 20.2.4 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I guess is not the right way ...

I've never used these tools on Windows. There might be a bit of learning curve with some of this, but don't be discouraged.

Poppler isn't a Python package. It's a program of its own. https://poppler.freedesktop.org/ That website has a link to a Windows version. https://ci.appveyor.com/project/tsdgeos/poppler-mirror

This following note may not be necessary but I want to mention it so you'll at least be aware: If you find yourself needing tools that don't exist for Windows, you can try something like Cygwin which will give you some Linux-like abilities at the Windows command line. https://www.cygwin.com/ But that's another big learning curve that I wouldn't explore until other options have been exhausted and if you're interested in spending time spinning wheels, because you'll get to learn about building sources from scratch and hunting down lots of dependencies.

Just to be sure, I should have installed Poppler, Tesseract and ImageMagick in order to compile your Python code ? Or Tesseract and ImageMagick is enough to be as Python package ?

eihli commented

It depends on what you want to do. Poppler is needed if you want to extract images from PDF files. ImageMagick is needed if you need to rotate images, like if they are rotated 90 degrees sideways. Tesseract is needed for recgonizing characters in the table cells.
