Open Source .NET QRCode Library
By admin on Sep 13, 2007 in .NET, open source, Programming
Today I released the source code for the .NET QRCode library.
.NET QRCode library is a .NET component that can be used to encode and decode QRCode. QRCode is a 2 dimensional bar code that originated in Japan. Nowadays it is widely used in a wide range of industries, e.g. for vehicle parts tracking and inventory management.
QRCode Library provides functions to:
- Encode content into a QR Code image which can saved in JPEG, GIF, PNG, or BITMAP formats
- Decode a QR Code image
The library can be used in any .NET 2.0 Windows Application, ASP.NET web application or Windows Mobile device application.
Some sample screenshots are displayed below:

More details on the component can be found on the website.

I am interested in QR Codes to automate some realtime tracking needs.
However, I have seen a system running on a Windows Mobile system that aquired the barcode in real-time via the built-in video capture (video, not pictures).
I would like to build a custom app similar both on Windows Vista (using a laptop’s built in webcam) and Windows Mobile (using built in webcam).
Can you make any suggestions on where to start with this? The video capture is the show stopper.

Hi. First of all thank you for developing this magnificient QR-Code Library!
I am currently programming an application for my company (a Steel manufacturer), which we will use to print product labels for identifying materials in our internal transport chain. We would like to print QR-Codes onto those labels, using your QR-Code library.
Given that our application may be considered commercial (even though its purley being used internally and not to be sold to others), I would greatly appreciate if you could OK our use of your library for the described purpose.
Thank you very much in advance!

This library is free to use for commercial purpose.
We are in the midst of porting this code. You are free to modify the code, and contribute back the changes back.
