lizettepreiss / FDFParser.py

Last active January 20, 2023 03:59

How to parse a .fdf file in Python. The intention was to export comments I'd made in a .pdf (using Adobe Reader DC's commenting capability) and make them available elsewhere to use as a basis for further notes.


	from pdfminer.pdfparser import PDFParser
	from pdfminer.pdfdocument import PDFDocument
	from pdfminer.pdftypes import resolve1

	# I exported the comments I had made in an Adobe Reader DC document to f:temp/stn.fdf.
	# Now I wanted to access those comments outside of the Adobe Reader. Here is how I extracted the comments.

	fdf_file = open("F:/temp/stn.fdf", 'rb')
