Different header strategies on each page

[Rogerlebrun]

Hello,

is there a way to have a header on the first page, but not on the second one, but then a different header on the third page, for example?

Also, what is the pdf structure? Is it a pdf contains sections which contain pages?

Thank you!

Hi,

Thanks for your inquiry.
Pdf has two structures, one contains sections which contain pages, the other just contains pages. No matter which kind of structure, both can use pdfDocument.Page[index] to select specific page.

Code: Select all

 PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("..\\..\\test.pdf");
            AddHeader1(doc.Pages[0]);
            AddHeader2(doc.Pages[2]);
            string output = "result.pdf";
            doc.SaveToFile(output);
            System.Diagnostics.Process.Start(output);
     
        public void AddHeader1(PdfPageBase page)
        {
            PdfSolidBrush brush = new PdfSolidBrush(System.Drawing.Color.Black);
            PdfStringFormat leftAlignment = new PdfStringFormat(PdfTextAlignment.Left, PdfVerticalAlignment.Top);

            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 8f, FontStyle.Regular), true);
            PdfMargins margins = page.Document.PageSettings.Margins;
            float space = font.Height;
            float x = margins.Left;
            float y = margins.Top-space;

            page.Canvas.DrawString("This is the first header", font, brush, new PointF(x,y), leftAlignment);
        }
        public void AddHeader2(PdfPageBase page)
        {
            PdfSolidBrush brush = new PdfSolidBrush(System.Drawing.Color.Black);
            PdfStringFormat leftAlignment = new PdfStringFormat(PdfTextAlignment.Left, PdfVerticalAlignment.Top);

            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 8f, FontStyle.Regular), true);
            PdfMargins margins = page.Document.PageSettings.Margins;
            float space = font.Height;
            float x = margins.Left;
            float y = margins.Top - space;

            page.Canvas.DrawString("This is the second header", font, brush, new PointF(x, y), leftAlignment);
        }
