Okay, so I'm going to take the off chance that someone here has used zxing before. I'm developing a Java application, and one of the things it needs to do is encode a byte array of data into a QR Code and then decode it at a later time.
Here's an example of what my encoder looks like:
byte[] b…

Hi,
I'm seeking an open source QR codes image generator component in java (J2SE), but the open source licence mustn't be a GPL licence (needs to be included in a close source project).
BTW, i can't access the web from the project so no Google API.

How can i diagonalize the matrix A having the orthogonal transformations P and Q: A = Q*B*P ? I saw something pointing out to QR transformations, but i couldn't find out the algorithm.

Looking for free/opensource code or description of algorithms to code (simple) and decode (hard) the 2D barcode QR code.
It doesn't seem like a trivial problem, but it's so popular in Japan that there must be something already available...

I use zxing to encode a qr code and store it as a bitmap and then show it in ImageView. Since the image generation time is significant I'm planning to move it to a separate thread (AsyncTaskLoader will be fine I think).
The problem is - it's an image and I know that to avoid memory leaks one should…

Hi,
When you download files from Google Code now (example), in addition to the text version of the SHA1 hash, it includes a QR code of it.
The device that the file was downloaded to is the one that has to hash the file. But, if it can download the file (ie, has access to the webpage), it also has…
