PDF Condenser

A tool to extract pages from a PDF that add a substantial amount of new content.

Requirements

• Python 3.4+ and modules defined in requirements.txt; can be installed with pip -r install
• Libraries for ImageMagick
• Linux (for now)

Usage

• Clone this repository
• Run pdf-condenser.py with an optional parameter of the PDF to be used (if one is not supplied, the program requests one from stdin)
• Condensed PDF is saved to the same directory as the original file with -condensed appended to filename
• Tips:
  • For PDFs with many pages, you may need to decrease RESOLUTION
  • Depending on the general content of the PDF (e.g. changing background), you may need to increase/decrease SIM_THRESHOLD
  • You can add this to your PATH variable to run it from wherever

Notes

• You may need to change the ImageMagick policies as defined in /etc/ImageMagick-*/policy.xml (e.g. comment out <policy domain="coder" rights="none" pattern="PDF" />)
