Adding footers to a PDF document is a useful way to provide additional information and context to the content within the document. Footers typically appear at the bottom of each page and can include elements such as page numbers, dates, copyright information, or any other relevant details. By incorporating footers, you can enhance the professionalism and organization of your PDF files, making them more informative and easier to navigate for readers. In this article, you will learn how to add a footer to an existing PDF document in C# and VB.NET using Spire.PDF for .NET.

Install Spire.PDF for .NET

To begin with, you need to add the DLLs included in the Spire.PDF for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

Background Knowledge

When an existing PDF document is manipulated by Spire.PDF for .NET, the origin of the coordinate system is located at the top left corner of the page, with the x-axis extending to the right and the y-axis extending downward. Adding a footer to a page means adding content, such as text, images, automatic fields and shapes, to a specified location in the bottom blank area of the page.

Add Header in PDF with C#/VB.NET

PDF header presents consistent information of a PDF document. It can be automatic page number, a date, a section title, an icon or an image. Whatever it is, it is an important part for a PDF file. This article will introduce how to add a header when programmatically creating a PDF document from scratch.

You can add both text and image in your PDF header by using Spire.PDF for .NET. In order to display the header content appropriately, you can also set text format and image size. The picture below shows the output after adding header in PDF:

Add Header in PDF with C#, VB.NET

Main Steps:

Step 1: Define a custom function CreateHeaderTemplate() to create a page template element that servers as header, and return a PdfPageDocumentElement object.

In the code below, we first initialize a page template object that can be used as header, then call DrawString() method, DrawImage() method and DrawLine() method to insert text,image and line into the header space.

static PdfPageTemplateElement CreateHeaderTemplate(PdfDocument doc, PdfMargins margins)
{
    //get page size
    SizeF pageSize = doc.PageSettings.Size;

    //create a PdfPageTemplateElement object as header space
    PdfPageTemplateElement headerSpace = new PdfPageTemplateElement(pageSize.Width, margins.Top);
    headerSpace.Foreground = false;

    //declare two float variables
    float x = margins.Left;
    float y = 0;

    //draw image in header space 
    PdfImage headerImage = PdfImage.FromFile("logo.png");
    float width = headerImage.Width / 3;
    float height = headerImage.Height / 3;
    headerSpace.Graphics.DrawImage(headerImage, x, margins.Top - height - 2, width, height);

    //draw line in header space
    PdfPen pen = new PdfPen(PdfBrushes.Gray, 1);
    headerSpace.Graphics.DrawLine(pen, x, y + margins.Top - 2, pageSize.Width - x, y + margins.Top - 2);

    //draw text in header space
    PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Impact", 25f, FontStyle.Bold));
    PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left);
    String headerText = "HEADER TEXT";
    SizeF size = font.MeasureString(headerText, format);
    headerSpace.Graphics.DrawString(headerText, font, PdfBrushes.Gray, pageSize.Width - x - size.Width-2, margins.Top- (size.Height+5), format);

    //return headerSpace
    return headerSpace;
}

Step 2: Create a PDF document, call the method CreateHeaderTemplate() to create a header template and apply it to the document.

static void Main(string[] args)
{
    //create a PDF document
    PdfDocument doc = new PdfDocument();
    doc.PageSettings.Size = PdfPageSize.A4;

    //reset the default margins to 0
    doc.PageSettings.Margins = new PdfMargins(0);

    //create a PdfMargins object, the parameters indicate the page margins you want to set
    PdfMargins margins = new PdfMargins(60, 60, 60, 60);

    //create a header template with content and apply it to page template
    doc.Template.Top = CreateHeaderTemplate(doc, margins);
    
    //apply blank templates to other parts of page template
    doc.Template.Bottom = new PdfPageTemplateElement(doc.PageSettings.Size.Width, margins.Bottom);
    doc.Template.Left = new PdfPageTemplateElement(margins.Left, doc.PageSettings.Size.Height);
    doc.Template.Right = new PdfPageTemplateElement(margins.Right, doc.PageSettings.Size.Height);

    //save the file
    doc.SaveToFile("PdfHeader.pdf");
}

Add PDF Footer in C#/VB.NET

A PDF header or footer presents consistent information (For example: a date, page numbering, the title of the overall document, or author’s name) in the page margins throughout a PDF. In this article, you will learn to add text and automatic page numbering to footer space when creating a PDF document from scratch.

Spire.PDF has a class named PdfPageTemplateElement, which represents a page template element that can be used as header, footer, watermark or stamp. The template can contain text, image as well as dynamic fields like PdfPageCountField, PdfPageNumberField, etc.

Step 1: Define a custom function CreateFooterTemplate() to create a page template element that servers as footer, and return a PdfPageDocumentElement object.

static PdfPageTemplateElement CreateFooterTemplate(PdfDocument doc, PdfMargins margins)
{
    //get page size
    SizeF pageSize = doc.PageSettings.Size;

    //create a PdfPageTemplateElement object which works as footer space
    PdfPageTemplateElement footerSpace = new PdfPageTemplateElement(pageSize.Width, margins.Bottom);
    footerSpace.Foreground = false;

    //declare two float variables
    float x = margins.Left;
    float y = 0;

    //draw line in footer space
    PdfPen pen = new PdfPen(PdfBrushes.Gray, 1);
    footerSpace.Graphics.DrawLine(pen, x, y, pageSize.Width - x, y);

    //draw text in footer space
    y = y + 5;
    PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Impact", 10f), true);
    PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left);
    String footerText = "E-iceblue Technology Co., Ltd.\nTel:028-81705109\nWebsite:http://www.e-iceblue.com";
    footerSpace.Graphics.DrawString(footerText, font, PdfBrushes.Gray, x, y, format);

    //draw dynamic field in footer space
    PdfPageNumberField number = new PdfPageNumberField();
    PdfPageCountField count = new PdfPageCountField();
    PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Gray, "Page {0} of {1}", number, count);
    compositeField.StringFormat = new PdfStringFormat(PdfTextAlignment.Right, PdfVerticalAlignment.Top);
    SizeF size = font.MeasureString(compositeField.Text);
    compositeField.Bounds = new RectangleF(pageSize.Width - x , y, size.Width, size.Height);
    compositeField.Draw(footerSpace.Graphics);

    //return footerSpace
    return footerSpace;
}

Step 2: Create a PDF document, call the method CreateFooterTemplate() to create a footer template and apply it to the document.

static void Main(string[] args)
{
    //create a PDF document
    PdfDocument doc = new PdfDocument();
    doc.PageSettings.Size = PdfPageSize.A4;

    //reset the default margins to 0
    doc.PageSettings.Margins = new PdfMargins(0);

    //create a PdfMargins object, the parameters indicate the page margins you want to set
    PdfMargins margins = new PdfMargins(60, 60, 60, 60);

    //create a footer template with content and apply it to bottom page template
    doc.Template.Bottom = CreateFooterTemplate(doc, margins);

    //apply blank templates to other parts of page template
    doc.Template.Top = new PdfPageTemplateElement(doc.PageSettings.Size.Width, margins.Top);
    doc.Template.Left = new PdfPageTemplateElement(margins.Left, doc.PageSettings.Size.Height);
    doc.Template.Right = new PdfPageTemplateElement(margins.Right, doc.PageSettings.Size.Height);

    //add two pages in the document
    doc.Pages.Add();
    doc.Pages.Add();

    //save the file
    doc.SaveToFile("PdfFooter.pdf");
}
