Multipage PDF#

This is a demo of creating a pdf file with several pages, as well as adding metadata and annotations to pdf files.

If you want to use a multipage pdf file using LaTeX, you need to use from matplotlib.backends.backend_pgf import PdfPages. This version however does not support attach_note.

import datetime import matplotlib.pyplot as plt import numpy as np from matplotlib.backends.backend_pdf import PdfPages # Create the PdfPages object to which we will save the pages: # The with statement makes sure that the PdfPages object is closed properly at # the end of the block, even if an Exception occurs. with PdfPages('multipage_pdf.pdf') as pdf: plt.figure(figsize=(3, 3)) plt.plot(range(7), [3, 1, 4, 1, 5, 9, 2], 'r-o') plt.title('Page One') pdf.savefig() # saves the current figure into a pdf page plt.close() # if LaTeX is not installed or error caught, change to `False` plt.rcParams['text.usetex'] = True plt.figure(figsize=(8, 6)) x = np.arange(0, 5, 0.1) plt.plot(x, np.sin(x), 'b-') plt.title('Page Two') pdf.attach_note("plot of sin(x)") # attach metadata (as pdf note) to page pdf.savefig() plt.close() plt.rcParams['text.usetex'] = False fig = plt.figure(figsize=(4, 5)) plt.plot(x, x ** 2, 'ko') plt.title('Page Three') pdf.savefig(fig) # or you can pass a Figure object to pdf.savefig plt.close() # We can also set the file's metadata via the PdfPages object: d = pdf.infodict() d['Title'] = 'Multipage PDF Example' d['Author'] = 'Jouni K. Sepp\xe4nen' d['Subject'] = 'How to create a multipage pdf file and set its metadata' d['Keywords'] = 'PdfPages multipage keywords author title subject' d['CreationDate'] = datetime.datetime(2009, 11, 13) d['ModDate'] = datetime.datetime.today()
