Hi,

I've been trying to convert a HTML document such as the following to a PDF

<!DOCTYPE html>
<html>
<head>
</head>
<body>
  <img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAyAAAADICAYAAAAQj4UaA....(truncated)">
  <p>SOME TEXT</p>
</body>
</html>

The code I'm using to convert it to a PDF is:

ITextRenderer renderer = new ITextRenderer();
renderer.documentFromString = htmlString;
renderer.layout();
renderer.createPDF(fileOutputStream, false);
renderer.finishPDF();

The generated PDF does not include the image, so I guess either I'm not generating the PDF correctly, or these kinds of images are not supported?

I'm using version 9.1.5, and I can see that support for base-64 encoded images does exist in this version, when the image data is provided via the "background-image" CSS property. So perhaps it's the case that I need to use this CSS property instead of the "src" HTML attribute?

Thanks in advance,

Donal
