Generate RGhost bar code inline (stream)

[jmarquesCC]

I'm using RGhost-Rails to generate bar codes on a pdf file (with wicked-pdf).

I've the following code (in Ruby on Rails 3)

 <% doc=RGhost::Document.new :paper => [7,2]%>
 <% doc.barcode_code39('1234567', :text => {:size => 10, :offset => [0,-10], :enable => [:text, :check, :checkintext] }) %>
 <% r= doc.render :png, :resolution => 100, :debug => true, :filename => "./public/pdf/rghost_barcode.png"  %>

This code works fine but i want to generate my image inline (without worrying with the filename and filepath). Something like (i guess):

<% doc=RGhost::Document.new :paper => [7,2]%>
<% doc.barcode_code39('1234567', :text => {:size => 10, :offset => [0,-10], :enable => [:text, :check, :checkintext] }) %>

<img src="<%= RGhost inline functionality/ r= doc.render_stream :png??? %>" width="16" height="335" alt="asd">

In this way, i wouldn't have to worry about deleting the (generated) code bar files after showing the pdf.

There is any way to do this?

You can do this using the url to your controller and invoking the code from your controller(without ERB), something like:

private

def barcodes doc=RGhost::Document.new :paper => [7,2] doc.barcode_code39('1234567', :text => {:size => 10, :offset => [0,-10], :enable => [:text, :check, :checkintext] }) send_data(doc.render_stream(:png), :type => "image/png", :disposition => 'inline') end

Hi,

I already had tried that solution... the problem is: the send_data function will sends the given binary data to the browser (so the browser will rendered the page as PNG (in this case)). :/
