Support for merging PDFs and 508 Accessibility Tags

[dependablejoe]

Is there any support, future, pending, current, or paid,  for retaining accessibility tags in PDF files when merging?

I am using iText 5.2.1.
I am using Java 1.6.0_26.


I have written code to merge two files, see source below.

Using Adobe Reader Pro X, I have verified that my two source files have accessibility tags and that the resultant file does not have the tags.



import java.io.*;
import java.util.*;


import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.text.pdf.PdfContentByte;

import com.itextpdf.text.pdf.PdfCopy;
import com.itextpdf.text.pdf.PdfImportedPage;


public class itext
{
        public itext() {};

        public void doAppend()
        {
                try {

                        PdfReader reader1 = new PdfReader ("file1.pdf");
                        PdfReader reader2 = new PdfReader ("file2.pdf");

                        PdfCopyFields copy = new PdfCopyFields(new FileOutputStream ("aNewPDF.pdf"));

                        copy.addDocument(reader1);
                        copy.addDocument(reader2);

                        copy.close();
                }
                catch(Exception de)
                {
                        System.out.println("exception: " + de.toString());
                }
        }

        public static void main (String[] argv)
        {
                itext itext = new itext();

                itext.doAppend();
        }
}

That would be a question for our paid professional services.

In tagged PDF, there is a StructTreeRoot that can be consulted to find the complete structure of a document.
From this structured tree, there are references to the corresponding content.
This is done using "Marked Content" operators in the content stream.

Merging these different structures probably isn't impossible, but it's not that trivial either.
Do you want iText Professional Services to make an assessment of the time it would take to implement this?

If you are simply appending entire documents, then it’s fairly straightforward (though not trivial).  Page range insertion (or deletion) of tags is quite complex.

Yes, I just have documents, which are both tagged, and want to simply append one to the other.

Straightforward and non-trivial sound fine to me.  Can you point me in the right direction to get started?

Not at this moment, thanks.

You will need to study the relevant sections of the PDF standard (ISO 32000-1:2008) to understand how the tagging/structure of PDF works.   Then you’ll need to modify the Appending capabilities of iText to handle the merging.  You might find that a special call is needed so that you do a block copy instead of page by page…

What you'll need to do is very close to what is done when you merge bookmarks whilst concatenating documents.
If I'm not mistaken, you should already have received a mail from Frank Gielen regarding professional services.
We're already doing some work for CSC in Belgium. Frank would be happy to discuss what can be done.
