Barcode Generator for Rails - ReDux

Barcode generator makes generating/displaying barcodes in any format like, PNG,JPEG,JPG etc.. for any alphanumeric id, a piece of cake.

It uses Gbarcode for encoding barcode data and ImageMagick to generate images out of it for displaying in views.(yes yes.. you read it correct, its NOT using RMagick anymore)

This way we can generate any barcode type which Gbarcode -> Gnome Barcode project supports.

USAGE

its as simple as saying

<%= barcode 'FJJ4JD'%> 

This will generate a barcode for FJJ4JD in BARCODE_39 format with default width and height and include it in the view.

the images are stored in /public/images/barcodes subdir.

Options Options Options ..

to customize your barcodes, you can optionally pass following information in your views

• encoding_format (Gbarcode constants for eg. Gbarcode::BARCODE_128 etc..)
• width
• height
• scaling_factor
• xoff
• yoff
• margin

<%= barcode 'ANUJ', :height => 100, 
                    :width  => 400,
		    :margin => 100,
		    :xoff   => 20,
		    :yoff   => 40
%> 

this will produce something beautiful like this ....
