How to introduce superscript? | iText 5 PDF Development Guide

How do I format dates so that the "th" in 14th or "rd" in 3rd is in superscript?

I want to format a date like this: 14th may 2015. However, the th in 14 should be in superscript as is what happens when you use the "sup" tag.

This is my code:

ph102 = new Phrase(csq.EventDate.Value.Day + Getsuffix(csq.EventDate.Value.Day) + csq.EventDate.Value.ToString("MMM") + " " + csq.EventDate.Value.Year + " at " + eventTime.ToString("hh:mm tt"), textFont7); PdfPCell cellt2 = new PdfPCell(ph102);

When I read your question, I assume that you want something like this:

Superscript

In your code, you create a Phrase like this:

This complete Phrase is expressed in textFont7 which can't work in your case, because you want to use a smaller font for the "st", "nd", "rd" or "th".

You need to do something like this (see OrdinalNumbers for the full example):

public void createPdf(String dest) throws IOException, DocumentException { Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream(dest)); document.open(); Font small = new Font(FontFamily.HELVETICA, 6); Chunk st = new Chunk("st", small); st.setTextRise(7); Chunk nd = new Chunk("nd", small); nd.setTextRise(7); Chunk rd = new Chunk("rd", small); rd.setTextRise(7); Chunk th = new Chunk("th", small); th.setTextRise(7); Paragraph first = new Paragraph(); first.add("The 1"); first.add(st); first.add(" of May"); document.add(first); Paragraph second = new Paragraph(); second.add("The 2"); second.add(nd); second.add(" and the 3"); second.add(rd); second.add(" of June"); document.add(second); Paragraph fourth = new Paragraph(); fourth.add("The 4"); fourth.add(rd); fourth.add(" of July"); document.add(fourth); document.close(); }

This is the Java code to create the PDF in the screen shot. You'll have to adapt your code so that it works in C#. As you can see, you can not just concatenate your strings using the + operator. You need to compose your Phrase or Paragraph using different Chunk objects. What you call "sup" is done by using a smaller font and a text rise.
