# ASCIITableToPDF.py
# Author: Vasudev Ram - http://www.dancingbison.com
# Demo program to show how to generate an ASCII table as PDF,
# using the xtopdf toolkit for PDF creation from Python.
# Generates a PDF file with information about the 
# first 32 ASCII codes, i.e. the control characters.
# Based on the ASCII Code table at http://www.ascii-code.com/
