Hi,
I want to add a watermark to the qr code generated automatically on generation. Is there a open source solution to start. We are trying to implement a organisation wide solution, but have to complete successful pilot to get it to make it organization standard.
I appreciate any help.
Thanks.

hello,
how can i generate QR Images from an URL and display them on a website?
ideally in PHP but any other popular server side language would work too, as long as it is not too complicated to set up.
thanks!

I was wondering if there is a good library for python for decoding QR code. Basically what I would like is to give library image with QR code on it and the library would output contents saved in image.

hello.
i'm trying to develop an app that integrates the qr code reader as part of the functionality.
i have read about zxing as the best option. but it turns out that they dont support development for blackberry, and the sample app shipped in zxing haves bugs (gives JVM runtime exception).
i wonder if anyone knows a viable alternative...
I am looking for a library or method to decode a QR Code (or potentially another form of 2d barcode) and to be able to actually determine the camera position and orientation. This seems like it should be doable, but I am not entirely sure.
Does anyone know what the best route for this is? Or if it is even possible?

I'm specifically asking if , and what, is the specification for formatting the text inside a QR code - not how to generate a code ( which I can do ).
I need to put hCard data into a QR code, however I don't know how to mark the QR code as VCF data ( vs url , vs text , vs etc ) so the decoder knows what to do.
All the info I've seen onl...
vCard? mecard? hCard?
Is there a de facto standard at this point? I've never personally owned a 'smartphone' -- is there a format that's supported 'out-of-the-box' for either iphone, android or blackberry?
edit:
found this discussion from last
year. Any thoughts?
this reader appears to be multiplatform and uses mecard
mecard sp...
The spec has 4 of these tables:

to handle versions 1-40
I'm wondering if anyone has coded something to formulate calculating the version needed for a string of data. None of the libraries I've seen for encoding the data offer this.

Is there a .NET API that generates QR Codes such as this one?
I'd like to display these on pages that I expect my users to print out.

In irb
data = "2 1058 657682"
barcode = Barby::QrCode.new(data)
File.open('barcode.png', 'w+')

Generates error:

The goal is to exchange small amounts of private data using AES encrypted QR-codes.

Is there a plain PHP implementation for decoding QR codes?
I have a faux-smartphone. One of those phones that parades as a smartphone but that I can't download any apps for, and I want to create an email service to where I can take a picture of a QR code, MMS it to this email, and the email returns what the QR code contains.
However, ...
Is zxing library will directly detect the QR code from an image without having to determine where the location of the QR code in the image?
...
Quick googling result that QR code can hold nearly 3kb (8 bit) data. But isn't it just using black/white dots to represent bits? If so there's no way that there's over 20,000 dots on a code.
So I'm obviously misunderstanding. Can someone explain how it works?
...
The built-in barcode scanner application on Android (based, I think, on zxing) reads QR Codes and launches that data into an application based on the leading text. For example, "BEGIN:VCAL" might launch a calendar application; "http:" might launch a browser.
How can I "register" my application so the OS (or the Barcode application) will...
