Zint is a comprehensive barcode generation toolkit that supports a large collection of one-dimensional and two-dimensional barcode standards. It is suitable for creating everything from conventional retail barcodes to QR codes, shipping labels and specialist industrial identifiers.
The package provides three ways to generate barcodes: a Qt-based graphical application called Zint Barcode Studio, a command-line utility for scripting and batch operations, and a C library that developers can integrate into their own applications.
Zint provides extensive control over barcode appearance and encoding. It is useful for producing individual symbols as well as integrating barcode generation into larger publishing, inventory and labelling workflows.
This is free and open source software.
