usps_intelligent_barcode is a pure ruby gem to generate a USPS IMB (Intelligent Mail Barcode). More specifically, it generates the string of characters you should print using one of the USPS Intelligent Barcode fonts.

ORIGIN

This project was forked from Ryan Taylor's https://github.com/rtlong/USPS-intelligent-barcode Long, in order to add tests and refactor. It is not a drop-in replacement: I renamed most methods and classes, and eliminated the #draw method.

INSTALL

$ gem install USPS-intelligent-barcode

EXAMPLE

#!/usr/bin/env ruby

require 'rubygems'
require 'usps_intelligent_barcode'

barcode_id = '01'
service_type = '234'
mailer_id = '567094'
serial_number = '987654321'
routing_code = '01234567891'
barcode = Imb::Barcode.new(barcode_id,
                           service_type,
                           mailer_id,
                           serial_number,
                           routing_code)
p barcode.barcode_letters
# => "AADTFFDFTDADTAADAATFDTDDAAADDTDTTDAFADADDDTFFFDDTTTADFAAADFTDAADA"
