Using itextsharp xmlworker to convert html to pdf and write text vertically

Answer 1

public void addHtmlToPdf(Document document, PdfWriter writer, String html) {
    PdfPTable table = new PdfPTable(1);
    PdfPCell cell = new PdfPCell();
    ElementList list = XMLWorkerHelper.ParseToElementList(html, null);
    foreach(IElement element in list) {
        cell.AddElement(element);
    }
    table.AddCell(cell);
    document.Add(table);
}

Alternative with utf8:

public void addHtmlToPdf_Utf8(Document document, PdfWriter writer, String html) 
{
    XMLWorkerHelper xml = XMLWorkerHelper.GetInstance();
    xml.ParseXHtml(writer, document, stringToStream(html), System.Text.Encoding.UTF8);
}
public Stream stringToStream(string txt) {
    var stream = new MemoryStream();
    var w = new StreamWriter(stream);
    w.Write(txt);
    w.Flush();
    stream.Position = 0;
    return stream;
}
