ITextPdf how to break a page

Question

I am creating a pdf file from an html page using iTextPdf, for example:

iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document); TextReader reader = new StringReader(HTML); hw.Parse(reader); document.Close(); 

but my html page is big and I need to add page inhibition in certain palms.

How to add these breaks to PDF?

thanks

Answer 1

There is HTMLWorker.ParseToList . Can't you use this?

• Get n items from ParseToList
• Add first x elements to PDF
• Call NewPage to PDF
• Add remaining items to PDF

Answer 2

Since iTextSharp has limitations in understanding several HTML styles / tags.

The solution to this is a small workaround:

• You need to create a new class that extends the HTMLWorker class and overrides the StartElement method, which gives us starting each html element.

   public class HTMLWorkerExtended : HTMLWorker { public HTMLWorkerExtended(IDocListener document): base(document) { } public override void StartElement(string tag, IDictionary<string, string> str) { if (tag.Equals("newpage")) document.Add(Chunk.NEXTPAGE); else base.StartElement(tag, str); } } 

• In your html, add the <newpage /> wherever you want to split the page.

• Now use the HTMLWorkerExtended class' object to parse the html.

   using (TextReader htmlViewReader = new StringReader(htmlText)) { using (var htmlWorker = new HTMLWorkerExtended(pdfDocument)) { htmlWorker.Open(); htmlWorker.Parse(htmlViewReader); } }
