Hello again!
Forget my last mail, it was non-sense. But I'm still unable to insert an empty page after an imported document. I've debugged a little bit but cannot find the reason.
Has somebody else an idea? This is my new snippet:
private void append(PdfReader reader) throws BadPdfFormatException,
IOException, DocumentException {
reader.consolidateNamedDestinations();
if (document == null) {
document = new Document(reader.getPageSizeWithRotation(1));
writer = new MyPdfCopy(document, out);
document.open();
}
final int n = reader.getNumberOfPages();
for (int i = 0; i < n; )
writer.addPage(writer.getImportedPage(reader, ++i));
if (reader.getAcroForm() != null)
writer.copyAcroForm(reader);
//if (forceEvenPageCount && (n%2 ==1) ){
document.add(new Chunk(" "));
document.newPage();
//}
}
Thanks a lot guys.

Hi Peter,
Thanks for the fast response. Unfortunately this doesn't work and I think the reason is:
When calling newPage() on a document, method newPage() is invoked for all document-listeners (interface DocListener). In my scenario the PdfCopy object (the writer) is the DocListener and for this class (super class DocWriter) method newPage() has an empty implementation...
Do I have to override methode newPage() in class PdfCopy? And the big question ist: what to do there?! Paulo?

Hi Sascha,
You need to add an empty Chunk to the new Page like this:
document.newPage();
document.add(new Chunk(""));
If you don't, the new page is not added.

Betreff: [iText-questions] Merging PDFs with blank pages
Hi!
I'm merging PDFs with iText and want to insert a blank page if a pdf file
has an odd total number of pages. It's needed for duplex printing...
Unfortunately it seems to me that method document.newPage() doesn't work
properly here?!?
Here is a snippet of my PDF-Merger; this method is called for each PDF
document:
private void append(PdfReader reader) throws BadPdfFormatException,
IOException, DocumentException {
reader.consolidateNamedDestinations();
if (document == null) {
document = new Document(reader.getPageSizeWithRotation(1));
writer = new PdfCopy(document, out);
document.open();
}
final int n = reader.getNumberOfPages();
for (int i = 0; i < n; ) {
writer.addPage(writer.getImportedPage(reader, ++i));
}
if (reader.getAcroForm() != null)
writer.copyAcroForm(reader);
//if (forceEvenPageCount && (n%2 ==1) ){
document.newPage();
//}
}
Can somebody help me please? Thanks in advance.
Sascha
