Hello,
Thanks a lot for the replay.
Yes, my bad, I should include appendPDF method from the beginning.
Here is the code :
private static final void appendPDF( final PdfCopy target, final PdfReader
source )
throws BadPdfFormatException, IOException
{
final int pages = source.getNumberOfPages();
for ( int i = 1; i <= pages; i++ )
{
target.addPage( target.getImportedPage( source, i ) );
}
}
Thank you,
Alexandre Pichtchikov

I checked this Merging Tagged PDF without ruining the
tags<http://stackoverflow.com/questions/19839445/merging-tagged-pdf-without-ruining-the-tags>,
and have found that it should be fixed, but it still exist at least in iText
5.5.2 I used. Is it any work around? Could PageName.PG be set manually? Thanks
in advance.
It looks like NullPointerException(PdfCopy.java:890) is generated at this line:
HashMap<Integer, PdfIndirectReference> numTree =
structureTreeRoot.getNumTree();//iText 5.5.2;PdfCopy.java:890
structureTreeRoot can be null in case the method getImportedPage(PdfReader,
int, boolean) was used without keeping tagged structure (which would be wrong
use of iText). Unfortunately, this code is hidden in your appendPDF() method so
we can't check if you're doing something wrong or if there's really a problem
inside iText.
The issue with a PG key has been fixed in iText 5.5.0.
