title: Insert an image into a pdf in ruby
body: <p>Does anyone know how to insert an image into a PDF with <strong>Ruby</strong>?</p>
  
  <p>I have been searching on the internet for some time, but most of the gems do not support the requirement. </p>
  
  <p>The image should be inserted into an existing PDF with content. The content should not be removed. May be you can say inserting an image overlay in the PDF. </p>
  
  <p>Thank you for help.</p>
