✍: FYIcenter.com
Here is a tutorial for copying PDF document and update it's information
using iText Java Library.
1. Create a Java file, PdfUpdate.java:
/** * Copy PDF and update info */ import com.itextpdf.kernel.pdf.*; import java.io.*; public class PdfUpdate { public static void main(String args[]) throws IOException { PdfReader reader = new PdfReader(args[0]); PdfWriter writer = new PdfWriter(args[1]); PdfDocument pdf = new PdfDocument(reader, writer); PdfDocumentInfo info = pdf.getDocumentInfo(); System.out.println("Title: "+info.getTitle()); System.out.println("Author: "+info.getAuthor()); System.out.println("Subject: "+info.getSubject()); System.out.println("Creator: "+info.getCreator()); System.out.println("Producer: "+info.getProducer()); info.setAuthor("FYIcenter.com"); info.setSubject("Test on updating PDF info"); // info.setProducer("iText7"); pdf.close(); } }
2. Run the Java program iText 7 Java Library.
fyicenter$ java -cp java -cp kernel-7.1.4.jar:layout-7.1.4.jar: \ io-7.1.4.jar:slf4j-api-1.7.31.jar \ PdfUpdate.java hello.pdf updated.pdf Title: null Subject: null Keywords: null Author: null Creator: null Producer: iText® 7.1.4 ©2000-2018 iText Group NV (AGPL-version); \ modified using iText® 7.1.4 ©2000-2018 iText Group NV (AGPL-version)
3. Check the updated PDF: updated.pdf.
fyicenter$ java -cp java -cp kernel-7.1.4.jar:layout-7.1.4.jar: \ io-7.1.4.jar:slf4j-api-1.7.31.jar \ PdfInfo.java updated.pdf Title: null Subject: Test on updating PDF info Keywords: null Author: FYIcenter.com Creator: null Producer: iText® 7.1.4 ©2000-2018 iText Group NV (AGPL-version); \ modified using iText® 7.1.4 ©2000-2018 iText Group NV (AGPL-version)
