Hi,
I had a code merging two PDFs, which was using setTagged in case both of
the concatenated PDFs are tagged (worked well with 5.4.3).
I've now downloaded the new release and all of a sudden the following
RUNTIME error appeared when closing the PDF (on the line:
document.close();):
Exception in thread "main" ExceptionConverter: java.io.IOException:

at Concatenate.main(Concatenate.java:108)
Here is the relevant code:
public static void main(String[] args)
throws IOException, DocumentException, SQLException {
String[] files=args;
// step 1
PdfReader reader_branding = new PdfReader(files[0]);
PdfReader reader = new PdfReader(System.in);
boolean setTagged=reader.isTagged() &&
reader_branding.isTagged();
Document document = new Document();
// step 2
PdfCopy copy = new PdfCopy(document, System.out);
if (setTagged)
{
copy.setTagged();
}
document.open();
int n;
// loop over the pages in that document
n = reader_branding.getNumberOfPages();
for (int page = 0; page < n; ) {
if (setTagged)
{
copy.addPage(copy.getImportedPage(reader_branding,
++page,true));
}else
{
copy.addPage(copy.getImportedPage(reader_branding,
++page));
};
}
copy.freeReader(reader_branding);
reader_branding.close();
//reader = new PdfReader(System.in);
// loop over the pages in that document
n = reader.getNumberOfPages();
for (int page = 0; page < n; ) {
if (setTagged)
{
copy.addPage(copy.getImportedPage(reader, ++page,true));
}else
{
copy.addPage(copy.getImportedPage(reader, ++page));
};
}
copy.freeReader(reader);
reader.close();
// step 5
document.close();
}
}
Would appreciate your kind help!
The reason I was updating to the new release is that albeit the
accessibility support on 5.4.3, the "read out loud" feature of Adobe failed
to read the output PDF (although it passed most of the accessibility tests,
but not all of them, of course).
JAWS also failed to read the document properly.
When I re-downloaded the "readoutloud.pdf" sample, I noticed that it was
updated and now readable by Adobe Reader, and when checking the properties
of the PDF it showed that the new version which worked was generated by
5.4.4 and this was the reason for the update (my main motivation to switch
to iText was the accessibility support).
Many thanks!
