ZBar is an open-source C library and software suite for reading bar codes from video streams, image files, and raw intensity sensors. It supports symbologies like EAN/UPC, Code 128, Code 39, Interleaved 2 of 5, and QR Code, with CLI tools, GUI widgets, and bindings for Python, Perl, and C++.
Use cases
- decode qr codes from images
- scan barcodes from a webcam video stream
- read upc codes from product photos in a script
- embed barcode scanning in an embedded c application
- add a barcode scanning widget to a qt or gtk app
- batch decode barcodes from image files via command line
When to choose
- you need a lightweight, fast C barcode decoder with a small memory footprint
- you want bindings for Python, Perl, or C++ or GUI widgets for Qt/GTK
- you target embedded or low-resource platforms without floating point requirements
- you need support for common 1D symbologies plus QR codes
When to avoid
- you need modern actively developed features or new symbologies
- you want a pure high-level language solution without C dependencies
- you need robust scanning of damaged or low-quality images with modern ML-based decoders
