Increase header size pdfMake

Question

I am trying to increase the header size on a pdf using pdfmake.

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.

• The margin can be decreased to increase the size but i want the margin to remain.
• I've searched pdfMake github for similar issues with no success.

If you need to test anything, try the code I have so far on pdfmake playground

Keep in mind you will need to copy and paste all this code on the "playground" to make it work.

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'
  ]
}

You need to add a pageMargins and adjust the second parameter (top margin) to your total header size. You can try values until you get all header content visible.

For example:

In this case, I use 80 (pageMargin: [40,80,40,60]) to get the image with height 60

var dd = {

    pageSize: 'LEGAL',
    pageOrientation: 'landscape',
    pageMargins: [40, 80, 40, 60],

    header: {
        margin: 8,
        columns: [
            {
                table: {
                    widths: [ '50%','50%'],

                    body: [
                        [
                            { image: 'sampleImage.jpg',

                                width: 80, height: 60,

                            },

                            { image: 'sampleImage.jpg',

                                width: 80, height: 60,
                                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'
    ]
}
