Barcode

This library provides functions with which EAN-codes (numeric) can be transformed into glyphs that can be displayed as Barcode using a specific Barcode-Font. Currently supported Barcodes: EAN 8, EAN 13

In this case, the EAN is transformed into Glyphs that can be displayed with the Open-Source Font LibreBarcode.
These fonts are included in the fonts-folder of this project renderpdf/comet/fonts/LibreBarcode(...).ttf.
