How to add Header & Footer in Existing PDF Document.

Postby tatvasoft » Fri Mar 28, 2014 7:06 am

Hello,

I want to add header and footer in existing pdf document in c#. Header contains logo, some text and Hyperlink, but while I am adding it using code given in example, I found one issue. Header is overlapped on Content of the Page.

My Requirement is while user upload any PDF file in Web Application then we need to add header, footer and watermark in PDF file which is uploaded by User.

Can you please suggest me how can I achieve this functionality using Spire.Doc.

Thanks,

Hello,

Thanks for your inquiry.
If the content of the header you want to add is bigger than the top white space of the existing Pdf, it will cover the content. Do you want to scroll down content of the PDF as the header or the header is under the content of the PDF. If convenient, could you please provide us your files?
Thanks,
Gary

Dear Gray Zhang

Thanks for reply.

Yes In case of White space of the PDF document is less than header height than I want to scroll down content. After scrolling content if Content is not fit in same then we also want to move remaining content to next page.

Thanks,

Dear Gray Zhang

Thanks for sharing code.

I gone through demo provided by you, and it is working as What I want, but still having one issue in it. Why it is not retain same margin (Left and Right) in newly generated file as per my original document. and also top margin is too much. Please find attached image file in which I describe the Original file, newly generated file and what is my expectation.

Please suggest.

Thanks,

Jignesh Chauhan

Hello,

Sorry for inconvenience. You need to adjust the position, and there are some code for your reference.
Code: Select all
class Program
    {
        static void Main(string[] args)
        {
            //Create a pdf document.
            PdfDocument doc = new PdfDocument();
            doc.PageSettings.Margins.All = 0;

            SetDocumentTemplate(doc, PdfPageSize.A4, 40);

            PdfDocument original = new PdfDocument();

            original.LoadFromFile(@"..\..\Sample.pdf");

            PdfPageBase page = null;

            foreach (PdfPageBase origianlPage in original.Pages)
            {
                page = doc.Pages.Add(new SizeF(origianlPage.Size.Width, origianlPage.Size.Height + 40));//add the TopSpace height
                origianlPage.CreateTemplate().Draw(page, 0, 0);

            }
            doc.PageSettings.Margins.Top = 40;
            doc.PageSettings.Margins.Left = 90;
            doc.SaveToFile("output.pdf");
            System.Diagnostics.Process.Start("output.pdf");
        }
        private static void SetDocumentTemplate(PdfDocument doc, SizeF pageSize, float height)//height, is the topSpace height depends on the added content
        {
            PdfPageTemplateElement topSpace = new PdfPageTemplateElement(pageSize.Width, height);
            topSpace.Foreground = true;
            doc.Template.Top = topSpace;

            //draw header label
            PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial", 20f));
            String label = "This is header for test";
            SizeF size1 = font1.MeasureString(label);
            float x = 0;
            float y = 0;
            topSpace.Graphics.DrawString(label, font1, PdfBrushes.PaleVioletRed, x, y);

            label = "Hello Word";
            PdfTrueTypeFont font2 = new PdfTrueTypeFont(new Font("Arial", 10f));
            y = y + size1.Height;
            topSpace.Graphics.DrawString(label, font2, PdfBrushes.Blue, x, y);
        }


    }

Hello,

Thanks for the sharing code. I check it and it looks good as per previously. I need to know two more things regarding PDF.

1. How to read content of PDF and display in Editor as same format as in PDF. (I think for that we need to convert PDF to HTML) so is it possible using Spire.PDF?

2. Adding watermark text in document.

Please reply ASAP.

Thanks,

Sorry that our product doesn't support the feature at present.
2. Adding watermark text in document.

Code: Select all
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"..\..\Sample.pdf");
PdfPageBase page = doc.Pages[0];
PdfTilingBrush brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 2, page.Canvas.ClientSize.Height / 3));
brush.Graphics.SetTransparency(0.3f);
brush.Graphics.Save();
brush.Graphics.TranslateTransform(brush.Size.Width / 2, brush.Size.Height / 2);
brush.Graphics.RotateTransform(-45);
brush.Graphics.DrawString("Spire.Pdf Demo", new PdfFont(PdfFontFamily.Helvetica, 24), PdfBrushes.Violet, 0, 0, new PdfStringFormat(PdfTextAlignment.Center));
brush.Graphics.Restore();
brush.Graphics.SetTransparency(1);
page.Canvas.DrawRectangle(brush, new RectangleF(new PointF(0, 0), page.Canvas.ClientSize));
doc.SaveToFile("TextWaterMark.pdf"); 

If there are any questisons, welcome to get it back to us.

Hello lisa,

I tried with sample code for adding watermark in PDF, It works perfectly, But need some more time to check with different scenario.

And also is there any way to get the content of PDF file along with same layout and display in web application (Editor)?

Thanks,

Hello,

Thanks for the reply.
Don't make sure what you need, but there is Spire.PdfViewer product you can try, which is a totally independent .NET library which designed for viewing PDF files from .NET application.
