PyFPDF

The pure Python PyFPDF library is a lightweight way to create PDFs, including maps. Because the PDF format is a widely used standard, PDFs are commonly used to distribute maps. You can install it via PyPI as fpdf.

The map will have header text at the top that says Hancock County Boundary, followed by the map image:

import fpdf
# PDF constructor:
# Portrait, millimeter units, A4 page size
pdf=fpdf.FPDF("P", "mm", "A4")
# create a new page
pdf.add_page()
# Set font: arial, bold, size 20
pdf.set_font('Arial','B',20)
# Layout cell: 160 x 25mm, title, no border, centered
pdf.cell(160,25,&apos...
