PDF Toolbox

About The Project

PDF Toolbox aims to be a PDF content extraction, conversion and creation program. The goal is to extract content via various methods and store it in a database for use in other document creation.

This should hopefully allow easier conversion to other formats and also let you create new documents using any text, tables pictures, etc you may already have available in other file formats.

All development work currently happens on the development branch and changes are merged frequently into main. Once a solid base has been formed a 0.1 release will be created and merges from the development branch will only be for security fixes, bug fixes and new versions.

Built With

• Python3
• PyMuPDF
• PyTesseract
• Adobe PDF Extract API

Getting Started

To get a local copy up and running follow these simple steps.

Prerequisites

• Adobe
  • Place Adobe PDF Extract API credentials in root of repository. Credentials are available from Adobe with a 1000 credit/six month free trial.
• Pillow/PIL
  • Install Python Imaging Library (or the Pillow fork) for your OS. Installation instructions available at the Pillow documentation.
• TesseractOCR
  • Install Tesseract OCR for your OS. Installation instructions available at the Tesseract OCR github repository.
• MuPDF
  • Install MuPDF for your OS. Installation instructions available at the MuPDF website.

Installation

1. Get a free API Key/Credentials at Adobe.
2. Clone the repo

   git clone https://github.com/hreikin/pdf-toolbox.git

3. Create and source a Python virtual environment.

   python3 -m venv .venv
   source .venv/bin/activate

4. Install requirements with pip

   pip install -r requirements.txt

Known Issues

On Linux (Windows/Mac untested) the file .venv/lib64/python3.9/site-packages/ado be/pdfservices/operation/internal/io/file_ref_impl.py from pdfservices-sdk inside the venv you create needs a few changes otherwise it might fail with a false cross-device link error.

Add import shutil to the top of the file and on line 46 alter it to the following to successfully save the JsonSchema/zip file it outputs. This does not deal with deleting the temporary file as it only copies it however with it being in temp it should be deleted on a reboot anyway so for now this hacky workaround should be ok:

shutil.copy(self._file_path, abs_path)

Comparison Scores

The file confidence.py creates three text files for comparison to create a rudimentary confidence check as one isn't provided by the API. The score is a comparison between the API's extraction and other extraction techniques. Scores are calculated using the SequenceMatcher class and get_close_matches method from difflib.

A score of 0.6 for any of the calculated scores is considered a close match. All scores are stored in a dictionary and a text file is created with the results.
