QR Code generator can generate QR-Codes based on the zxing library. All files can be imported on the fly from a maven repository or can be downloaded via a command. Zxing is an open source project so it also possible to include your self-compliled files if you have security issues.

Great code and very useful. One question about capacity as I am trying to generate codes as small as possible. As far I can find out, a version 1 code should be able to be 21x21 pixels and hold 25 alphanumeric characters. However, when I use the code and try to create a "Hello Hello World" (two hello) which is only 17 characters, it generates a 25x25 code instead of the expected 21x21. Why is that? Thanks!
can this code be used to convert a binary image to QR coded image.
Sorry its me again. I solved my previous problem. But I have another question: the QR code size is changed with the figure window size, right? So could we somehow fix the size of QR code into a specific size? Thanks!
Hi Jens, Thank you very much for this package! It's very helpful! But I have a question for you: if I want generate many QR codes in a loop and combine them by using `subplot`, when should I call `subplot'? My goal is to print out all the QR codes in an A4 paper. Many thanks!
please check the manual. You can download the jars easily and use them without internet connection. Please feel free to send me an email in case you need a helping hand :-).
output is performd only with the internet usage..how to get without connection also?
thanks! very useful!
I dont know if anyone used this within Matlab but it seems not be to complicated. I had a look on the following java implementation https://github.com/zxing/zxing/blob/master/core/src/main/java/com/google/zxing/datamatrix/DataMatrixWriter.java. I will have a look into this for my next release. If is of benefit I will include it :-)
Do you know whether anyone has done this with other codes in zxing, especially datamatrix codes?
Following your code I was able to get datamatrix codes:
e.g., dm_writer = com.google.zxing.datamatrix.DataMatrixWriter;
However, my rudimentary abilities keep me from figuring out the different options available in datamatrix codes (except for DATA_MATRIX_SHAPE).
Do you know where I can find a list of encoder options for datamatrix codes in zxing?
thank you very much for your comment. I will publish a new version of Qr Code Generator in the next days anyway. Because there is also a bug when running it with Matlab2015a. I will also have a look on the quietzone settings.
It looks like the setting for the quiet zone is not implemented in the java. When I change this value in qrcode_config.m, nothing happens. If I try putting it in the hints (qr_hints.put(com.google.zxing.EncodeHintType.MARGIN, qrcodeProps.setting.quietZoneSize)), I get an error. I tried looking at the java source and it likes like this part isn't fully implemented.
Does this seem right to you?
