title: Rotate image in PDF using Prawn gem
body: <p>I am updating an existing Ruby on Rails application and creating a PDF using the rawn gem.</p>
  
  <p>I can rotate <code>text</code> and <code>text_box</code>es, but I'm unable to rotate images.</p>
  
  <p>Can Prawn be used to rotate images?</p>
  
  <p>The Prawn documentation says you can configure the image dimensions by setting the width and height or by scaling it, but not rotate it.</p>
