title: TCPDF font spacing too wide
body: <p>I have this code that has worked in the past:</p>
  
  <pre><code>$pdf = new TCPDF('L', 'In', 'LETTER', true); 
  $pdf-&gt;SetPrintHeader(false);    
  $pdf-&gt;SetPrintFooter(false);    
  $pdf-&gt;SetFont('Times','B',11);
  $pdf-&gt;AddPage();
  $pdf-&gt;SetLeftMargin(0.5);
  $pdf-&gt;SetLineWidth(.04);
  $pdf-&gt;Rect(.5, .5, 10, 7.5);
  $pdf-&gt;SetLineWidth(.01);
  $pdf-&gt;Rect(.55, .55, 9.89, 7.39);
  $pdf-&gt;setFont('Times', 'BI', 31);
  $pdf-&gt;SetXY(0.5,0.9);
  $pdf-&gt;Cell( 9.75, 0.5, 'Certificate of Completion',0,1,'C');
  $pdf-&gt;setFont('Helvetica', 'B', 11);
  $pdf-&gt;SetXY(0.5,1.75);
  $pdf-&gt;Cell( 9.75, 0.2, 'Course Work or Training in Infection Control',0,1,'C');
  $pdf-&gt;Cell( 9.75, 0.2, 'Approved by', 0, 1, 'C');
  $pdf-&gt;Cell( 9.75, 0.2, 'The New York State Department of Health &amp;', 0, 1, 'C');
  $pdf-&gt;Cell( 9.75, 0.2, 'The New York State Department of Education', 0, 1, 'C');
  </code></pre>
  
  <p>Now the output looks like this:
  <img src="https://i.stack.imgur.com/b65HC.jpg" alt="Bad PDF"></p>
  
  <p>I tried adding this:</p>
  
  <pre><code>$pdf-&gt;setFontSpacing(100);  
  </code></pre>
  
  <p>but the script failed to execute.</p>
  
  <p>What is wrong?</p>
