Open Source Java QR Code Generators for Linux

ZXingLite for Android is a simplified and extremely fast version of ZXing. Based on the ZXing library, it optimizes the functions of scanning codes and generating QR codes/barcodes. The scanning interface fully supports customization, and one line of code can also use the default scanning function. In short, everything you want is here. By inheriting CaptureActivity or CaptureFragment and customizing the layout. (Applicable to most scenarios, and you don’t need to care about the code scanning related logic, you need to override the getLayoutId method when customizing the layout) Implementation examples: CustomCaptureActivity and QRCodeActivity. Instantiate a CameraScan in the Activity or Fragment of your project. (Applicable to use when you want to write interactive logic on the code scanning interface, and cannot directly or indirectly inherit CaptureActivity or CaptureFragment due to project architecture or other reasons)

QRGen creates QR codes from contact information, written in Java. It requires the tool qrencode in order to work, qrencode is freely available at http://fukuchi.org/works/qrencode (Linux/Mac OS/UNIX) , or http://code.google.com/p/qrencode-win32/ (Windows), or Ubuntu Software Centre.

QR Code Generator by Aspose.BarCode for Java is a web application to generate various types of QR Codes using Aspose.BarCode for Java. http://goo.gl/GqUMog

SlowQR allows to scan QR codes from images. Some manual interaction for distorted codes is possible. Due to missing hardware-accelerated drawing support, automatic recognition may be slow, hence the name. New features: - creation/editing of QR codes. - support of images with perspective - optional experimental offscreen hardware acceleration (via openGL 2-FBOs)
