Hi,

I am searching for a way to dynamically generate a barcode as part of  
a PDF.

I have come across a number of older threads and discussions but no  
one seemed to confirm a tested working solution.

I wondered if anyone had since tackled the problem?

There are innumerable free implementations of barcode generation. I  
don’t  
know of a wrapper around one of the libraries, but it should be pretty  
simple to implement. Perhaps this library would be a good start:

Write a C extension and you’re good to go. Once you have the output in  
some  
format, you should be able to turn it into a PDF one way or another  
(e.g.  
RMagick).

[barby.rubyforge.org](http://barby.rubyforge.org) ?

No idea on speed though.
