I'm out of luck anyway, even with iText 5.2.1.
Just out of curiosity, I tried the brand new latest release of iText but
the result does not change: with the code below (adapted from section
6.2 of the iText book) the OCGs somehow are not transferred correctly.
-----------
PdfReader reader = new PdfReader(pdf);
Document document = new Document(PageSize.A4);
ByteArrayOutputStream os = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(document, os);
writer.setPdfVersion(PdfWriter.PDF_VERSION_1_5);
document.open();
PdfContentByte cb = writer.getDirectContent();
int n = reader.getNumberOfPages();
for (int i = 1; i <= n; i++) {
PdfImportedPage page = writer.getImportedPage(reader, i);
cb.addTemplate(page, 1, 1);
document.newPage();
}
document.close();
return os.toByteArray();
