How to "decode" eexec of font file?

Question

I have a .pfa font file and I would like to read the "algorithm" for rendering the font. However, most of the information is hidden in binary in the line:

currentfile eexec

How do we "decode" this information?

Answer 1

Unless you really want to write your own eexec decryption, and then your own charstring decryption, I'd suggest you simply use t1disasm. If you are running on a Linux distribution you may be able to find a package for t1utils which should contain this, or you can get the source in a number of places (Google is your friend), here's one:

http://freepcb.googlecode.com/svn/clibpdf/trunk/util/t1utils-1.9/t1disasm.c

If you are on Windows you could look here for the t1utils package fopr WIndows :
