   Have any of you deep-in-the-craft Makers ever seen the algorithm by which QR Code is *de*coded (dot_pattern -> text)?

   I’ve been hunting for over a year now, and the closest i’ve come is “there is a function for that written in java for a project that’s now dead on this link that is broken …”

   It’s said that this algorithm has been openly released (from Japanese industry-land) …but where? behind some pay-for-ACTA-IEEE wall, or what?

   Thank’ee!

   Check out the QR Code library:

   and the Japanese one that you mentioned (which is in Japanese) is here:

   Thank you Sir! That qrcode.sourceforge.jp link has considerably more than I had seen elsewhere.
