Hide / Remove the DHMLX created watermark (footer) sentence when export pdf or png

Question

Exporting gantt with dhtmlx works fine, but I wondered if there is a way to hide or remove the sentence in watermark (footer):

This document is created with dhtmlx library: http://dhtmlx.com

This sentence is generated when export to pdf or png at the bottom of the doc (even below footer)

Answer 1

I found a way to hide for free the watermark by using the footer using position: absolute. This example will use background red but you can use another color.

Based on the dhtmlx ExporttoPDF we can easily modify the css by using a <style> element, so I did something like this:

HTML FOR EXPORT TO PDF:

<input type="button" onclick='gantt.exportToPDF({
  footer:`<style>
            #footer-container{ position:relative; }
            h4{ width:100%; background: red; position: absolute; top:-10px; }
          </style>
          <div id="footer-container">
            <h4>Bottom Line</h4>
          </div>`
})'>

CSS included in HTML above FOR EXPORT TO PDF:

#footer-container{
  position:relative;
} 
h4{
  position: absolute;
  top:-10px;
  width:100%;
  background: red;
}

HTML FOR EXPORT TO PNG:

<input type="button" onclick='gantt.exportToPNG({
  footer:`<style>
            #footer-container{ position:relative; }
            h4{ width:100%; background: red; position: absolute; top:-10px; }
          </style>
          <div id="footer-container">
            <h4>Bottom Line</h4>
          </div>`
})'>

CSS included in HTML above FOR EXPORT TO PNG:

#footer-container{
  position:relative;
}
h4{
  position: absolute;
  top:-10px;
  width:100%;
  background: red;
}

Output:
