title: TCPDF Page Margin Issue
body: <p>I'm creating PDF files with PHP using TCPDF. I have a small problem with created PDF files.
  I would like to set up right and left margin of each PDF file created. Currently if there is 10px margin on the left side, there is 20px margin on the right side.</p>
  
  <p>How do I set up right and left page margin?</p>
  
  <p>Thank you all for your time and concern.</p>
  
  <p>I tried following;</p>
  
  <p><code>$pdf-&gt;SetMargins(10, 10, -50, true);</code> and <code>$pdf-&gt;SetRightMargin(-50);</code> without any luck.</p>
