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 by Terry Burton together in the same project rghost_barcode.

 require 'rghost'
 require 'rghost_barcode'  
 doc=RGhost::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     

h2. Generate barcode catalog

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

See the catalog with 32 kinds of barcodes

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_barcodename(code(String), options(Hash) )

Example for PDF417

doc=RGhost::Document.new 
doc.barcode_pdf417 '^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.
