Hello,
I'm trying to recreate a PDF by reading it and rebuild it as a new
document using the attached code.
The original file contains layers (Optional Content Groups = OCG) which
were introduced with PDF-1.5. This almost works except that layers
disappear in the final output.
What am I doing wrong?
I'm using iText 2.1.7 (yes, it's old but it's at least unencumbered by
licensing problems)
Here is the essential code
--------------
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();
