Itextsharp: how to place text in the middle of the page

Question

I use the following code to create a cover page.

public static byte[] CreatePageHeader(List<string> texts) { var stream = new MemoryStream(); Document doc = null; try { doc = new Document(); PdfWriter.GetInstance(doc, stream); doc.SetMargins(50, 50, 50, 50); doc.SetPageSize(new iTextSharp.text.Rectangle(iTextSharp.text.PageSize.LETTER.Width, iTextSharp.text.PageSize.LETTER.Height)); Font font = new Font(Font.FontFamily.HELVETICA, 10f, Font.NORMAL); doc.Open(); Paragraph para = null; foreach (string text in texts) { para = new Paragraph(text, font); doc.Add(para); } } catch (Exception ex) { throw ex; } finally { doc.Close(); } return stream.ToArray(); } 

this works fine, but it shows the text at the top of the page. But I want it to be in the middle of the page.

How do I change this code?

For this, I would use only one row, one column table. These objects support a fixed width / height setting, which allows you to "center" things.

 var outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf"); using (var fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None)) { using (var doc = new Document()) { using (var writer = PdfWriter.GetInstance(doc, fs)) { doc.Open(); //Create a single column table var t = new PdfPTable(1); //Tell it to fill the page horizontally t.WidthPercentage = 100; //Create a single cell var c = new PdfPCell(); //Tell the cell to vertically align in the middle c.VerticalAlignment = Element.ALIGN_MIDDLE; //Tell the cell to fill the page vertically c.MinimumHeight = doc.PageSize.Height - (doc.BottomMargin + doc.TopMargin); //Create a test paragraph var p = new Paragraph("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam iaculis sem diam, quis accumsan ipsum venenatis ac. Pellentesque nec gravida tortor. Suspendisse dapibus quis quam sed sollicitudin."); //Add it a couple of times c.AddElement(p); c.AddElement(p); //Add the cell to the paragraph t.AddCell(c); //Add the table to the document doc.Add(t); doc.Close(); } } }
