To make changes to the footer or header of exported documents, you will need to modify the following files:

  • For the header - <template folder>/common/header.html
  • For the footer - <template folder>/common/footer.html

You can add a logo to the header or footer in one of the following ways:

  • Encode the logo image as the Base64 encoded string and use it as the value of the img src attribute.

  • Add a URL to the remote image as the value of the img src attribute.

    • The URL must be absolute, relative URLs do not work.
    • The URL must be accessible from the server where Web Application Platform is deployed.

Example of adding a logo to the header as a Base64 encoded string

Let’s say you want to use a logo in the header of the exported PDF file pages.


To add a logo to the header as a Base64 encoded string

  1. Encode the image as a Base64 string. You can use an online converter or use your own code/tools to make the conversion.
  2. Open the <template folder>/common/header.html file.
  3. Find the header tag.
  4. Add the img tag with <img src="{data:image/<image type>;base64,<Image as a Base64 encoded string> }" alt="<alt text>">

  5. Use other HTML tags and CSS styling information to display the logo image the way you want. Your code may look like the one below if you use a PNG image and want some padding around the image:

Example of adding a logo to the footer using an absolute URL to the image

Let’s say you want to use a logo in the footer of the exported PDF file pages. In this example, we will use an absolute URL as the image source.


To add a logo to the footer using an absolute URL to the image

  1. Open the <template folder>/common/footer.html file.
  2. Find the footer tag.
  3. Add the img tag with <img src"http(s)://path_to_image" alt="<alt text>" >

  4. Use other HTML tags and CSS styling information to display the image the way you want. Your code may look like this (the CSS is inline for simplicity):

    Code example
    <footer class="footer"
      xmlns:th="http://www.w3.org/1999/xhtml">
   
<div style="padding: 0 0 5px 5px; float: left; height: 25px;">
      <img src="https://www.3ds.com/assets/3ds-navigation/3DS_corporate-logo_blue.svg" 
           alt="Logo" style="width: auto;
           height:100%;
           object-fit: cover;">
   </div>   
   <div th:text="|${pagination.currentPageNumber}/${pagination.documentPagesSize}|" class="footer-text">
   </div>
</footer>
