Ruby Ghostscript Barcode

Now(after rghost version 0.8), you can easily create 32 kinds of barcode in Ruby using RGhost and Barcode Writer in Pure PostScript together in the same project rghost_barcode.

require 'rghost'
require 'rghost_barcode'
include RGhost

doc=Document.new
doc.barcode_code39('1234567', :x => 5, :y=> 10)        

After that you can convert the barcode to pdf, png, jpeg, tif and other formats or use it inside the document.

Installation

# gem install rghost
# gem install rghost_barcode      

or

 # gem install rghost_barcode -y      

Generate barcode catalog

 RGhost::Config.barcode_examples.render :pdf, :filename => '/tmp/barcodes.pdf'  

Architecture

All barcodes will be available as the factory method of the class Document prefixed by barcode_. The following grammar is used
Document_instance.barcode_name_of_barcode(code(String), options(Hash) )

Example for PDF147

doc=Document.new 
doc.barcode_pdf147('^453^178^121^239',:columns => 2,  :rows=> 10, :text => {:size => 10})      

Supported codes

auspost, azteccode, code11, code128, code2of5, code39, code93, datamatrix, ean13, ean2, ean5, ean8, interleaved2of5, isbn, kix, maxicode, msi, onecode, pdf417, pharmacode, plessey, postnet, qrcode, rationalizedcodabar, raw, royalmail, rss14, rssexpanded, rsslimited, symbol, upca and upce.
