title: TCPDF - How to adjust height of header?
body: <p>I am using TCPDF to convert html to pdf format.  I am passing a string into the php script to be set as my header. I am having a hard time setting the height of my header.  I have tried using <code>SetMargins(PDF_MARGIN_LEFT, 0, PDF_MARGIN_RIGHT)</code> and <code>SetHeaderMargin(0)</code>. What it did was to only take off the top margin. I have also alternately looked into adjusting the height of the cell which contains the string within the header.  </p>
  
  <pre><code>$this-&gt;Cell(0, 0, $newHeaderString, 0, false, 'C', 0, '', 0, false, 'M', 'M');
  </code></pre>
  
  <p>No luck eliminating white space here either.</p>
  
  <p>I have included an image to show what white space I want to eliminate.  The white space is between the header text and the hr tag from the html. Any help would be appreciated! </p>
