How it works

To demonstrate the powerful high-level capabilities of the iText 7 library, here is a simple "Hello World!" example showing how to create a PDF in just a few lines of Java or C#:

import com.itextpdf.kernel.pdf.*; import com.itextpdf.layout.Document; import com.itextpdf.layout.element.Paragraph; import*; public class HelloWorld { public static final String DEST = "/myfiles/hello.pdf"; public static void main(String args[]) throws IOException { PdfDocument pdf = new PdfDocument(new PdfWriter(DEST)); Document document = new Document(pdf); String line = "Hello! Welcome to iTextPdf"; document.add(new Paragraph(line)); document.close(); System.out.println("Awesome PDF just got created."); } }
using System; using System.IO; using iText.Kernel.Pdf; using iText.Layout; using iText.Layout.Element; class Program { static void Main() { PdfDocument pdfDocument = new PdfDocument(new PdfWriter(new FileStream("/myfiles/hello.pdf", FileMode.Create, FileAccess.Write))); Document document = new Document(pdfDocument); String line = "Hello! Welcome to iTextPdf"; document.Add(new Paragraph(line)); document.Close(); Console.WriteLine("Awesome PDF just got created."); } }
