reed solomon library

I'm about writing a qr code generator , should I write reed solomon error correction methods by myself or is there an开发者_Go百科y free library in PHP or Python to do that ?

thank you

Yes.. There is an QR code library in PHP. Check the link below: http://phpqrcode.sourceforge.net/

Here's a Python and Google Chart solution.

This came up high on google, so why not point you to this one:

I created a Python package galois that extends NumPy arrays over Galois fields. The Galois field arithmetic is written in Python but JIT compiled with Numba. So the arithmetic is as fast, or nearly as fast, as native NumPy.

Included in the library are Reed-Solomon codes.
