Hi,
I have 200+ existing pdf documents that I would like to combine into one pdf
file. The first couple of pages should be a table of contents that would allow
the user to click on a name and go to the correct page.
My plan was to use PdfStamper on each pdf file to place a new page number on
each page, then use PdfCopy to merge the documents together.
What I need help with is how to create the table of contents.
table of contents example:
001.pdf page 3 - 5 (Click here to go to page 3)
002.pdf page 6 - 12 (Click here to go to page 6)
...
200.pdf page 535-537 (Click here to go to page 535)
My first attempt was to create the table of contents from the PdfCopy document.
I couldn't figure out where the content was going. It didn't appear in the
output document.
if (f == 0) {
document = new Document(reader.getPageSizeWithRotation(1));
writer = new PdfCopy(document, new FileOutputStream(outFile));
document.open();
document.add(new Paragraph("001.pdf Page 3-5")); // never made it to the pdf
document.add(new Paragraph("002.pdf Page 6-12"));
document.newPage();
}
for (int i = 0; i < n; ) {
++i;
page = writer.getImportedPage(reader, i);
writer.addPage(page);
}
My second attempt was to create the table of contents as a separate document
using Anchors then merge it later. I would always get an exception on the
document.close stating the destination could not be found.
// create table of contents pdf
document.add(new Paragraph("001.pdf Page 3-5"));
Anchor anchor2 = new Anchor("Go to the internal link");
anchor2.setReference("#" + "a.pdf");
document.add(anchor2);
would throw
Exception in thread "main" java.lang.RuntimeException: The name 'a.pdf' has no
local destination.
at com.lowagie.text.pdf.PdfWriter.addLocalDestinations(PdfWriter.java:1726)
at com.lowagie.text.pdf.PdfDocument.close(PdfDocument.java:926)
at com.lowagie.text.Document.close(Document.java:520)
How do I add Paragraphs with local goto action then merge other pdf documents
using PdfCopy?
