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 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"
