Generate pdf file with Itext PDF and Freemarker : blank image using base64

Question

I've been looking for the solution to why the image doesn't show up using base64 encoded string in the pdf file. I have java class to generate pdf report with itextpdf and freemarker template. there is logo image that I want to pass to the report. the logo value using base64 encoded string with format as following:

data:image/jpg;base64,base64EncodedString

here is the freemarker template:

  <#macro header logo>
  <header>
    <table width="800">
      <tr>
          <#if logo??>
            <td width="300"> 
              <img src="https://cdn.pixabay.com/photo/2016/03/08/20/03/flag-1244649_960_720.jpg" width="60" height="60" align="left"/>
              <img src="${logo}" width="60" height="60" align="left"/>
            </td>
          </#if>
      </tr>
    </table>
    <br/>
  </header>

</#macro>

the first image using url path is working, however the second image using base64 is blank. the image is appear when I run it through jsfiddle or using html file https://jsfiddle.net/riskiana/jvug1tzL/3/

please somebody help me.

iText html2pdf currently doesn't support base 64 encoded resources.
