title: Increase header size pdfMake
body: <p>I am trying to increase the header size on a pdf using pdfmake.  </p>
  
  <p>Currently am able to get a header on both the left and right of the page, which is what I want, but when the height passes 26, the image disappears because there is a limited amount of space for the header. </p>
  
  <ul>
  <li>The margin can be decreased to increase the size but i want the
  margin to remain.</li>
  <li>I've searched pdfMake github for similar issues with no success.</li>
  </ul>
  
  <p>If you need to test anything, try the code I have so far on
  <a href="http://pdfmake.org/playground" rel="noreferrer">pdfmake playground</a></p>
  
  <p>Keep in mind you will need to copy and paste all this code on the "playground" to make it work.</p>
  
  <pre><code>var dd = {
    pageSize: 'LEGAL',
    pageOrientation: 'landscape',
    header: {
      margin: 8,
      columns: [{
        table: {
          widths: ['50%', '50%'],
          body: [
            [{
              image: 'sampleImage.jpg',
              width: 80,
              height: 26,
            }, {
              image: 'sampleImage.jpg',
              width: 80,
              height: 26,
              alignment: 'right'
            }]
          ]
        },
        layout: 'noBorders'
      }]
    },
    content: [
      'First paragraph',
      'Another paragraph, this time a little bit longer to make sure, this line will be divided into at least two lines'
    ]
  }
