A simple python3 script for inverting the colors of PDFs, whilst keeping the pdf format and vector nature of the document.
Basic usage:
python invertPDF.py [path1] [path2] [path3] ...where every path is either a directory or a file. Every file and file inside a folder path will have an inverted copy created
at its location with an added _inverted.pdf suffix. See
python invertPDF.py -hfor advanced usage.
