How to create a simple PDF Pie Chart using fitz / PyMuPDF (Python)

2017-07-10T16:07:51-07:00

Python recipe 580810 by Jorj X. McKie (fitz, pdf_generation).

PyMuPDF now supports drawing pie charts on a PDF page.

Important parameters for the function are center of the circle, one of the two arc's end points and the angle of the circular sector. The function will draw the pie piece (in a variety of options) and return the arc's calculated other end point for any subsequent processing.
