资源说明：Rails plugin to generate/display barcode in your views
BarcodeGenerator
================
### Author : Anuj Luthra
Barcode generator makes generating/displaying bar-codes for certain
alphanumeric ids a piece of cake.
It uses Gbarcode for encoding barcode data and then rmagick to generate
images out of it for displaying in views.
This way we can generate any barcode type which Gbarcode -> Gnome Barcode project
supports.
## Ruby1.9 note
please use ruby1.9 compatible gbarcode at [github repository by andreas](https://github.com/ahx/gbarcode) . Good work mate.
### 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/system/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
+ no_ascii (accepts boolean true or false, prevents the ascii string from printing at the bottom of the barcode)
in this case your view will look like :
<%= barcode 'ANUJ', :height => 100,
:width => 400,
:margin => 100,
:xoff => 20,
:yoff => 40
%>
### Installation:
