title: Acrobat Reader prompt saving pdf file when closing it (created with TCPDF)
body: <p>my problem is with the pdf opened in Acrobat Reader, created with TCPDF on ZF2.</p>
  
  <p>The file is created fine (except the size of the file, around 500kb), content is fine, but when trying to close the file, Acrobat prompts for saving the changes, though there is no changes. After saving the file and overwriting, the file size drops to around 40kb. So the file size is reduced over 10 times, but there is no visible change in the contents or otherwise.</p>
  
  <p>Closest I got to any related answer was this thread here <a href="http://forums.planetpdf.com/save-file-prompt-when-closing_topic36.html" rel="nofollow">http://forums.planetpdf.com/save-file-prompt-when-closing_topic36.html</a></p>
  
  <p>As I understand the issue is related to "The xref table is malformed", but my experience with pdf is not enough to understand the root of my problem. Sample file is available here <a href="https://dl.dropboxusercontent.com/u/29072870/test_pdf.pdf" rel="nofollow">https://dl.dropboxusercontent.com/u/29072870/test_pdf.pdf</a></p>
  
  <p>Thanks in advance!</p>
