# PDFKit

Create PDFs using plain old HTML+CSS. Uses [wkhtmltopdf](http://github.com/antialize/wkhtmltopdf) on the backend which renders HTML using Webkit.

## Installation

1. Install wkhtmltopdf
   # Download the latest binary from http://code.google.com/p/wkhtmltopdf/downloads/list
   # Place the binary somewhere on your path (e.g /usr/local/bin)
2. Install PDFKit
   # $ gem install pdfkit
   
## Usage
    
    # PDFKit.new takes the HTML and any options for wkhtmltopdf
    # run `wkhtmltopdf --extended-help` for a full list of options
    kit = PDFKit.new(html, :page_size => 'Letter')
    kit.stylesheets << '/path/to/css/file'
    
    # Git an inline PDF
    pdf = kit.to_pdf
    
    # Save the PDF to a file
    File.open('/path/to/save/pdf','w') {|file| file << pdf}
   
## Middleware

PDFKit comes with a middleware that allows users to visit any to get a PDF view of any page on your site by appending ?pdf=true to the URL.

## Note on Patches/Pull Requests
 
* Fork the project.
* Make your feature addition or bug fix.
* Add tests for it. This is important so I don't break it in a
  future version unintentionally.
* Commit, do not mess with rakefile, version, or history.
  (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
* Send me a pull request. Bonus points for topic branches.
