To highlight a text, you need to set its background color like this: Chunk dog = new Chunk("the lazy dog", new Font(Font.TIMES_ROMAN, 14, Font.ITALIC)); dog.setBackground(new Color(0xFF, 0x00, 0x00), 10, -50, 20, -10);

Thanks for your reply. I tried to make use of Chunk method as suggested by you. But I am not getting how to read an existing pdf file and set the background color of a perticular text in the pdf. e.g, I am reading a pdf like this: PdfReader read = new PdfReader ( "C:\Test.pdf" ); let's say the pdf contains text like : " iTextSharp is an efficient tool to work on pdf file." Now I want to highlight a perticular text say "iTextSharp" of the existing pdf file. So after reading the pdf how to use Chunk method to highlight the text.

Hi, What 3rd party application are you using in accessing the pdf? If you don't have a 3rd party application yet, try using iTextSharp.
