CSS does not apply while converting HTML to PDF using iTextSharp XMLWorker

Question

I am currently working on a POC to demonstrate conversion of HTML to PDF using iTextSharp XMLWorker class.

The CSS file is linked to HTML file using link tag.
The path of CSS file is a file server path. Its the same directory as the HTML file.

I use the below function to perform the operation. The PDF file gets generated but the CSS file is not applied.

public void Html2Pdf(FileStream inputHtml, Document doc, PdfWriter pdfWriter)
{
   var cssFiles = new CssFilesImpl();
   cssFiles.Add(XMLWorkerHelper.GetCSS(new FileStream(@"C:\Test_HTML2PDF\Test.css",FileMode.Open)));
   var cssResolver = new StyleAttrCSSResolver(cssFiles);

   var htmlContext = new HtmlPipelineContext(new CssAppliersImpl(new XMLWorkerFontProvider()));
   htmlContext.SetAcceptUnknown(true).AutoBookmark(true).SetTagFactory(Tags.GetHtmlTagProcessorFactory());

   htmlContext.SetPageSize(new Rectangle(doc.Left, doc.Bottom, doc.Right, doc.Top));

   // Pipelines

   var pdf = new PdfWriterPipeline(doc, pdfWriter);
        var html = new HtmlPipeline(htmlContext, pdf);
        var css = new CssResolverPipeline(cssResolver, html);

   var worker = new XMLWorker(css, true);
   var parser = new XMLParser(worker, Encoding.UTF8);
   parser.Parse(inputHtml, Encoding.UTF8);     
}

Kindly share your inputs / observations on what i have missed and what could be done address this issue.

HTML-to-PDF converters are notoriously bad with finding relative paths to assets. Try linking your stylesheet using an absolute URL instead, e.g.:

<link href='http://localhost/css/style.css'>
