com.itextpdf.barcodes.BarcodeCodabar

public class BarcodeCodabar
extends Barcode1D

Implementation of the Codabar barcode.

Codabar was designed to be accurately read even when printed on dot-matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007. Although newer symbologies hold more information in a smaller space.
