// Creating a Chunk with a specific text, font, and style Chunk heading = new Chunk("Example Heading"); heading.Font = FontFactory.GetFont(FontFactory.HELVETICA, 18, Font.BOLD); // Creating a Chunk with text, font, color, and style Chunk paragraph = new Chunk("This is an example paragraph"); paragraph.Font = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12, Font.NORMAL, BaseColor.BLACK); // Adding the chunks to the document document.Add(heading); document.Add(paragraph);In the above code example, we create two different chunks, one for the heading and one for the paragraph. We set the font, size, color, and style for each chunk and then add them to the document using the `Add` method. This will create a PDF document with the specified formatting options. Overall, the iTextSharp package library provides various functionalities to create, edit, and manipulate PDF documents in C#. The Chunk class is one such fundamental building block in creating PDF documents with customized formatting options.
