Barcode test sheet

A test sheet with every kind of barcode, one per page: QR codes of every version, Data Matrix up to its largest size, PDF417, Code 128 and EAN-13, some with Unicode text. Tagua’s CI renders it and decodes every code with an independent reader, which must read back exactly what was encoded.

Render it yourself

Save the template, put the fonts it names next to it (Inter and the Noto fonts are free, under the SIL Open Font License), and run:

tagua render barcodes.report.yaml --open

Without a data file, tagua render makes up sample rows from the field types; see Preview as you edit.
