title: layering PDFs together and have ability to set the position
body: <p>I'm being tasked to enhance the way we create custom brochures, the  old way we had a legacy system create the needed pdfs and then I would download those and "glue" them into one big pdf.</p>
  
  <p>the new one way we want to go about this is to skip the legacy system and build all of these things from our new system.</p>
  
  <p>The biggest hurdle is the cover, which consists of the background layer, and then the logo layer which has the company logo, a shadowbox and an emblem. all of these objects are pdf documents.</p>
  
  <p>my problem is after I build the logo portion, how will I be able to position the pdf exactly where I need it on the background layer?</p>
  
  <p>this is all being done on the fly so I can't save anything to disk.</p>
  
  <p>any help will be greatly appreciated.</p>
