Hi.
I need some help.
I was searching for how to write on an existing PDF file.
I have this code here:
Code:
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
            PdfDocument PDFDoc = PdfReader.Open(@"C:\Users\Userofthispc\Documents\Test.pdf", PdfDocumentOpenMode.Import);
            PdfDocument PDFNewDoc = new PdfDocument();

            for (int Pg = 0; Pg < PDFDoc.Pages.Count; Pg++)
            {
                PdfPage pp = PDFNewDoc.AddPage(PDFDoc.Pages[Pg]);

                XGraphics gfx = XGraphics.FromPdfPage(pp);
                XFont font = new XFont("Arial", 30, XFontStyle.Italic);
                gfx.DrawString("Hello, World!", font, XBrushes.Black, new XRect(pp.Width / 2, pp.Height / 2 + 85, pp.Width, pp.Height), XStringFormats.Center);
            }

            PDFNewDoc.Save(@"C:\Users\Userofthispc\Documents\Testv2.pdf");


The code should work (I think), but when I run it, it doesn't write anything.
Can you help me?

Try "new XRect(0, 0, pp.Width, pp.Height)".
Do you see text now?

Strange, I had that before and it was not working. And now it is!

Thank you!
How can I move it up a little bit?

The rectangle you specify in the code in the first post is mostly outside of the visible page region. The text is centred and also out of sight.
