Qt EAN-13 Barcode
EAN stands for European Article Number; it is a 13-digit numeric code that uniquely identifies a commercially sold product. It is a superset of the american UPC or Universal Product Code. This article shows a basic class with which to encode and draw an EAN-13/UPC barcode onto an arbitrary rectangle on a QPaintDevice. A trivial program to illustrate the use of the class is given at the end. The Wikipedia article on EAN-13 gives a good overview of the algorith used by the code and further detail was found. This class is an adaptation of rainman_63's C# code for QT. The class was written for a 1200dpi laser printer - readability may be an issue with lower resolutions or inkjets. You may get better results by turning antialiasing off. With an HP Laserjet 2550 the output is consistently readable with a standard barcode scanner at the nominal size of 37.29x25.93mm.
