prison is a Qt-based barcode abstraction layer/library and provides uniform access to generation of barcodes with data.
prison has a prison::AbstractBarcode, which is the base class for the actual barcode generators, currently prison::QRCodeBarcode and prison::DataMatrixBarcode is the two implemented barcode generators.
There is basically two types of barcodes:
- barcodes that carries the data
- barcodes that carries a lookup number, and requires a specific server to look up the actual data.
prison isn't as such designed for the latter, it will probably work, but patches implementing barcode support for such barcodes will not be accepted. A example is EZCode.
