Dear List,
Sorry, I sent this by mistake to list admin.
Is it possible to add a new OCG layer (with content) to an existing PDF
using PdfStamper?
This code adds a Page Resource Properties dictionary but no OCProperties
dictionary
static void Main(string[] args)
{
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, new
FileStream("Stampee.pdf", FileMode.Create));
writer.PdfVersion = PdfWriter.VERSION_1_6;
document.Open();
document.Add(new Paragraph("Hello World"));
document.Close();
PdfReader reader = new PdfReader("Stampee.pdf");
PdfStamper stamper = new PdfStamper(reader, new
FileStream("Stamper.pdf", FileMode.Create));
stamper.Writer.PdfVersion = PdfWriter.VERSION_1_6;
BaseFont bf = BaseFont.CreateFont(
BaseFont.HELVETICA, BaseFont.WINANSI, BaseFont.NOT_EMBEDDED);
PdfLayer layer = new PdfLayer("one", stamper.Writer);
PdfContentByte cbUnder = stamper.GetUnderContent(1);
cbUnder.BeginLayer(layer);
cbUnder.EndLayer();
stamper.Close();
}
Can I add content to an existing layer, using PdfStamper?
Thanks
AlanK
