PDF Reskeletonize

Proof of concept for re-skeletonizing PDFs.

Requirements

• PyPDF2 with PR #240 applied

Usage

python reskeletonize.py

• outline.json specifies a list of template objects in the outline PDF, their x/y coordinates, and their width & height.
• submission.json specifies a list of objects from the template that are present in the submission PDF, and their x/y coordinates.

Coordinates are all in inches, and the origin is at the bottom left of a page. PDF page numbers are 1-indexed (page 1 is the first page of a PDF).

Examples

Examples are generated with PyFPDF. PyFPDF sets the origin at the top left of a page.

Outline

        "id": "box1",
