Hello Piyawat,

Thanks for your inquiry.
If you want to add header image/text for the exsiting pdf file. Please refer to the following code.

Code: Select all

        static void Main(string[] args)
         {
           PdfDocument sourcePDF = new PdfDocument();
            sourcePDF.LoadFromFile("Sample.pdf");

            PdfDocument newPdf = new PdfDocument();
            PdfMargins margins = new PdfMargins(30f, 165f, 30f, 198f);

            PdfPageBase newPage;
            string headerImageFile = "1.png";
            string headerText = "Form P.Q. 7-2\nแบบ พ.ก. ๗-๒";
            foreach (PdfPageBase sourcePage in sourcePDF.Pages)
            {
                SizeF newPageSize =new SizeF(sourcePage.Size.Width+margins.Left+margins.Right,sourcePage.Size.Height+margins.Top+margins.Bottom);
                newPage = newPdf.Pages.Add(newPageSize, new PdfMargins(0));
                sourcePage.CreateTemplate().Draw(newPage.Canvas, margins.Left, margins.Top);
                SetDocumentHeaderTemplate(newPage,margins,headerImageFile,headerText);
            }
                   
            string outputfilepath = "output.pdf";
            newPdf.SaveToFile(outputfilepath);
            System.Diagnostics.Process.Start(outputfilepath);
         
        }
        static void SetDocumentHeaderTemplate(PdfPageBase page,PdfMargins margins,string headerImageFile,string headerText)
        {
            PdfImage headerImage = PdfImage.FromFile(headerImageFile);
            page.Canvas.DrawImage(headerImage, new PointF(230, 46), new SizeF(65, 66));

            PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial Unicode MS", 12, FontStyle.Regular), true);
            SizeF textSize = font1.MeasureString(headerText);
            page.Canvas.DrawString(headerText, font1, PdfBrushes.Black, page.Size.Width - margins.Right-textSize.Width, 5);
        }

Hello,

Thanks for your feedback!

If you want to add header image/text only the second page of the existing pdf file, just change this part of the code my colleague provided.

Code: Select all

.......
            foreach (PdfPageBase sourcePage in sourcePDF.Pages)
            {
                SizeF newPageSize = new SizeF(sourcePage.Size.Width + margins.Left + margins.Right, sourcePage.Size.Height + margins.Top + margins.Bottom);
                newPage = newPdf.Pages.Add(newPageSize, new PdfMargins(0));
                if(newPdf.Pages.IndexOf(sourcePage) == 1) //just set header of the second page
                {
                    SetDocumentHeaderTemplate(newPage, margins, headerImageFile, headerText);
                }
                sourcePage.CreateTemplate().Draw(newPage.Canvas, margins.Left, margins.Top);
               
            }
.......
