title: Ruby Parse PDF file having text and images
body: <p>I have a pdf file having both <strong>text</strong> and <strong>images</strong> contents. I need to parse it. Is there any ruby gem can be useful? I have tried <a href="https://github.com/yob/pdf-reader" rel="nofollow">pdf-reader</a> ruby gem but didn't parse images :(</p>
  
  <p>One alternative solution is to extract the pdf to html and then parse the html contents. Is there any open source pdf2html convertor can work with <strong>both</strong> text and images?</p>
