ZBar is a software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors.
It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 9, Interleaved 2 of 5 and QR Code.
The flexible, layered implementation facilitates bar code scanning and decoding for any application: use it stand-alone with the included GUI and command line programs, easily integrate a bar code scanning widget into your Qt, GTK or PyGTK GUI application, leverage one of the script or programming interfaces (Python, Perl, C ) ...all the way down to a streamlined C library suitable for embedded use.
