zint is a barcode generator supporting over 50 barcode types. It creates 1D barcodes (Code 128, EAN, UPC), 2D barcodes (QR Code, Data Matrix, PDF417), and specialized formats (postal codes, pharmaceutical).Output formats include PNG, BMP, GIF, PCX, SVG, EPS, and EMF. The tool can also output raw hex dumps for debugging or custom rendering.zint includes both a command-line interface and a GUI (zint-qt). A library (libzint) is available for integration into applications.

CAVEATS

Different barcode types have different data requirements. Some accept only numbers, others have length restrictions.QR codes and other 2D barcodes have error correction levels that trade capacity for redundancy.Not all barcode scanners support all symbologies. Verify compatibility with target readers.
