Open a template and use it

[Rajesh]

Hello,

We have a pdf document which contains header and footer. We want to want that document on every new document we create.

Doing a very basic thing , but new content is not being written (doc2.pdf is the file which contains our header and footer, I have attached it)

            string infileName = "C:\\Users\\bhard\\OneDrive\\Documents\\Doc2.pdf";

            string outfileName = "C:\\Users\\bhard\\OneDrive\\Documents\\Doc2_out.pdf";

            using FileStream inputStream = new(infileName, FileMode.OpenOrCreate, FileAccess.Read, FileShare.Read);

            using FileStream outputStream = new(outfileName, FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write);

            //Loads an existing PDF document.

            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(inputStream);

            //Get the first page of the document.

            PdfPageBase page = loadedDocument.Pages[0];

            //Create a page template.

            PdfPageTemplate pageTemplate = new PdfPageTemplate(page);

            //Sets the PdfPageTemplate name.

            pageTemplate.Name = "pageTemplate";

            //Sets the PdfPageTemplate is visible.

            pageTemplate.IsVisible = true;

            //Adds the page template.

            loadedDocument.PdfPageTemplates.Add(pageTemplate);

            /*

            DataTable dataTable = new DataTable();

            //Add columns to the DataTable

            dataTable.Columns.Add("ID");

            dataTable.Columns.Add("Name");

            //Add rows to the DataTable.

            dataTable.Rows.Add(new object[] { "E01", "Clay" });

            dataTable.Rows.Add(new object[] { "E02", "Thomas" });

            //Assign data source.

            PdfGrid pdfGrid = new PdfGrid();

            pdfGrid.DataSource = dataTable;

            //Draw grid to the page of PDF document.

            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 24);

            PdfBrush brush = new PdfSolidBrush(Color.Red);

            page.Graphics.DrawString("salamlar", font, brush, new PointF(10, 10));

            */

            //Create PDF graphics for the page.

            PdfGraphics graphics = page.Graphics;

            //Set the standard font.

            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);

            //Draw the text.

            graphics.DrawString("Hello World!!!", font, PdfBrushes.Black, new PointF(0, 0));

            //Save the PDF document.

            loadedDocument.Save(outputStream);

            //Close the PDF document.

            loadedDocument.Close(true);
