C#: Add, Modify, or Remove Footers in PowerPoint Documents

Adding, modifying, and removing footers in a PowerPoint document is crucial for enhancing the professionalism and readability of a presentation. By adding footers, you can include key information such as presentation titles, authors, dates, or page numbers, which helps the audience better understand the content. Modifying footers allows you to update information, making it more attractive and practical. Additionally, removing footers is also necessary, especially in certain situations such as when specific information is not required to be displayed at the bottom of each page for a particular occasion. In this article, you will learn how to add, modify, or remove footers in PowerPoint documents in C# using Spire.Presentation for .NET.

C# Add Footers in PowerPoint Documents

Spire.Presentation enables the addition of footer, slide number, and date placeholders at the bottom of PowerPoint document pages to uniformly add the same footer content across all pages. Here are the detailed steps:

Create a Presentation object.
Load a PowerPoint document using the lisentation.LoadFromFile() method.
Set Presentation.FooterVisible = true to make the footer visible and set the footer text.
Set Presentation.SlideNumberVisible = true to make slide numbers visible, then iterate through each slide, check for the existence of a slide number placeholder, and modify the text to "Slide X" format if found.
Set Presentation.DateTimeVisible = true to make date and time visible.
Use the Presentation.SetDateTime() method to set the date format.
Save the document using the Presentation.SaveToFile() method.

C#

using Spire.Presentation;

namespace SpirePresentationDemo
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Create a Presentation object
            Presentation presentation = new Presentation();

            // Load the presentation from a file
            presentation.LoadFromFile("Sample1.pptx");

            // Set the footer visible
            presentation.FooterVisible = true;

            // Set the footer text to "Spire.Presentation"
            presentation.SetFooterText("Spire.Presentation");

            // Set slide number visible
            presentation.SlideNumberVisible = true;

            // Iterate through each slide in the presentation
            foreach (ISlide slide in presentation.Slides)
            {
                foreach (IShape shape in slide.Shapes)
                {
                    if (shape.Placeholder != null)
                    {
                        // If it is a slide number placeholder
                        if (shape.Placeholder.Type.Equals(PlaceholderType.SlideNumber))
                        {
                            TextParagraph textParagraph = (shape as IAutoShape).TextFrame.TextRange.Paragraph;
                            String text = textParagraph.Text;

                            // Modify the slide number text to "Slide X"
                            textParagraph.Text = "Slide " + text;
                        }
                    }
                }
            }

            // Set date time visible
            presentation.DateTimeVisible = true;

            // Set date time format
            presentation.SetDateTime(DateTime.Now, "MM/dd/yyyy");

            // Save the modified presentation to a file
            presentation.SaveToFile("AddFooter.pptx", FileFormat.Pptx2016);

            // Dispose of the Presentation object resources

C# Modify Footers in PowerPoint Documents

To modify footers in a PowerPoint document, you first need to individually inspect the shapes on each slide, identify footer placeholders, page number placeholders, etc., and then set specific content and formats for each type of placeholder. Here are the detailed steps:

Create a Presentation object.
Load a PowerPoint document using the Presentation.LoadFromFile() method.
Use the Presentation.Slides[index] property to retrieve a slide.
Use a for loop to iterate through the shapes on the slide, individually checking each shape to determine if it is a placeholder for a footer, page number, etc., and then modify its content or format accordingly.
Save the document using the Presentation.SaveToFile() method.

C#

using Spire.Presentation;

namespace SpirePresentationDemo
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Create a Presentation object
            Presentation presentation = new Presentation();

            // Load the presentation from a file
            presentation.LoadFromFile("Sample2.pptx");

            // Get the first slide
            ISlide slide = presentation.Slides[0];

            // Iterate through shapes in the slide
            for (int i = 0; i < slide.Shapes.Count; i++)
            {
                // Check if the shape is a placeholder
                if (slide.Shapes[i].Placeholder != null)
                {
                    // Get the placeholder type
                    PlaceholderType type = slide.Shapes[i].Placeholder.Type;

                    // If it is a footer placeholder
                    if (type == PlaceholderType.Footer)
                    {
                        // Convert the shape to IAutoShape type
                        IAutoShape autoShape = (IAutoShape)slide.Shapes[i];

                        // Set the text content to "E-ICEBLUE"
                        autoShape.TextFrame.Text = "E-ICEBLUE";

                        // Modify the text font
                        ChangeFont1(autoShape.TextFrame.Paragraphs[0]);
                    }
                    // If it is a slide number placeholder
                    if (type == PlaceholderType.SlideNumber)
                    {
                        // Convert the shape to IAutoShape type
                        IAutoShape autoShape = (IAutoShape)slide.Shapes[i];

                        // Modify the text font
                        ChangeFont1(autoShape.TextFrame.Paragraphs[0]);
                    }
                }
            }

            // Save the modified presentation to a file
            presentation.SaveToFile("ModifyFooter.pptx", FileFormat.Pptx2016);

            // Dispose of the Presentation object resources
            presentation.Dispose();
        }
       static void ChangeFont1(TextParagraph paragraph)
        {
            // Iterate through each text range in the paragraph
            foreach (TextRange textRange in paragraph.TextRanges)
            {
                // Set the text style to italic
                textRange.IsItalic = TriState.True;

                // Set the text font
                textRange.EastAsianFont = new TextFont("Times New Roman");

                // Set the text font size to 34
                textRange.FontHeight = 34;

                // Set the text color
                textRange.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
                textRange.Fill.SolidColor.Color = System.Drawing.Color.LightSkyBlue;
            }

Add a Paragraph to PowerPoint file

PPT file format is a vivid and explicit way to present your stuff. PPT file can be very beautiful and powerful. And text is a basic element that PPT supports. Spire.Presentation is a powerful .NET component specially designed for developers. It enables developers to manipulate PPT files easily and flexibly. In this document, I will introduce you how to add a paragraph to PPT file using Spire.Presentation.

Step 1. Create a PPT document.

Presentation presentation = new Presentation();

Step 2. Add a new shape to the document.

IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 70, 450, 150));
shape.Fill.FillType = FillFormatType.None;
shape.ShapeStyle.LineColor.Color = Color.White;

Shape represents a TextBox in PPT document.

Step 3. Add some text to the shape.

shape.TextFrame.Text = "This powerful component suite contains the most up-to-date versions of all .NET WPF Silverlight components offered by E-iceblue.";

These will form a new paragraph.

Step 4. Set the alignment of the paragraph.

shape.TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Left;

Step 5. Set the indent of the paragraph.

shape.TextFrame.Paragraphs[0].Indent = 25*2;

Step 6. Set the line spacing of the paragraph.

shape.TextFrame.Paragraphs[0].LineSpacing = 250;

Step 7. Save the document.

presentation.SaveToFile("para.pptx", FileFormat.Pptx2010);

How to convert PowerPoint to PPTX in C#?

PPT is the file format used by Microsoft PowerPoint Presentation 97 - 2003, while PPTX is created by PowerPoint Presentation 2007, 2010. PPTX file format enjoys the advantages of smaller size, higher security, and higher integration with other file formats. But the Microsoft Office version under 2007 cannot open PPTX PowerPoint presentation directly. This article will show you how to convert PPT file format to PPTX in C# with only three lines of code.

Make sure Spire.Presentation for .NET has been installed correctly and then add Spire.Presentation.dll as reference in the downloaded Bin folder though the below path: "..\Spire.Presentation\Bin\NET4.0\ Spire. Presentation.dll". Here comes to the details of how to output PPT to PPTX:

Step 1: Create a presentation document.

Presentation presentation = new Presentation();

Step 2: Load the PPT file from disk.

presentation.LoadFromFile(@"..\..\..\..\..\..\Data\sample4.ppt");

Step 3: Save the PPT document to PPTX file format.

presentation.SaveToFile("ToPPTX.pptx", FileFormat.Pptx2010);

Step4: Launch and view the resulted PPTX file.

System.Diagnostics.Process.Start("ToPPTX.pptx");

Full codes:

namespace Spire.Presentation.Demo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnRun_Click(object sender, EventArgs e)
        {
            //create PPT document
            Presentation presentation = new Presentation();

            //load the PPT file from disk
            presentation.LoadFromFile(@"..\..\..\..\..\..\Data\sample4.ppt");

            //save the PPT document to PPTX file format
            presentation.SaveToFile("ToPPTX.pptx", FileFormat.Pptx2010);
            System.Diagnostics.Process.Start("ToPPTX.pptx");

namespace CreateNumberedList
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create a Presentation object
            Presentation presentation = new Presentation();
            //Get the first slide
            ISlide slide = presentation.Slides[0];

            //Add a shape to the slide and set the shape style
            IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 300, 200));
            shape.Fill.FillType = FillFormatType.None;
            shape.Line.FillType= FillFormatType.None;

            //Add text to the default paragraph
            TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
            paragraph.Text = "Required Web Development Skills:";
            paragraph.Alignment = TextAlignmentType.Left;
            paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
            paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;

            //Specify the list items
            string[] listItems = new string[] {
                " Command-line Unix",
                " Vim",

            //Create a numbered list
            foreach (string item in listItems)
            {
                TextParagraph textParagraph = new TextParagraph();
                textParagraph.Text = item;
                textParagraph.Alignment = TextAlignmentType.Left;
                textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
                textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;

                textParagraph.BulletType = TextBulletType.Numbered;

            Presentation presentation = new Presentation();
            //Get the first slide
            ISlide slide = presentation.Slides[0];

            //Add a shape to the slide and set the shape style
            IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 350, 200));
            shape.Fill.FillType = FillFormatType.None;
            shape.Line.FillType = FillFormatType.None;

            //Add text to the default paragraph
            TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
            paragraph.Text = "Computer Science Subjects:";

            //Specify the list items
            string[] listItems = new string[] {
                " Data Structure",
                " Algorithm",
                " Computer Networks",
                " Operating System",

                " C Programming",
                " Computer Organization and Architecture"
            };

            //Create a symbol bulleted list
            foreach (string item in listItems)
            {
                TextParagraph textParagraph = new TextParagraph();
                textParagraph.Text = item;
                textParagraph.Alignment = TextAlignmentType.Left;
                textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;

C#
VB.NET

using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;

namespace CreateImageBulletedList
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create a Presentation object
            Presentation presentation = new Presentation();
            //Get the first slide
            ISlide slide = presentation.Slides[0];

            //Add a shape to the slide and set the shape style
            IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 400, 180));
            shape.Fill.FillType = FillFormatType.None;
            shape.Line.FillType = FillFormatType.None;

            //Add text to the default paragraph
            TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
            paragraph.Text = "Project Task To-Do List:";
            paragraph.Alignment = TextAlignmentType.Left;
            paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
            paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;

            //Specify the list items
            string[] listItems = new string[] {
                " Define projects and tasks you're working on",
                " Assign people to tasks",
                " Define the priority levels of your tasks",

Step 2: Add the text to the shape.

shape.AppendTextFrame("This is a demo of text font and color.");

Step 3: Get the property TextRange of the text.

TextRange textRange = shape.TextFrame.TextRange;

Step 4: Set the Font of the text in shape.

textRange.FontHeight = 21;
textRange.IsItalic = TriState.True;
textRange.TextUnderlineType = TextUnderlineType.Single;
textRange.LatinFont = new TextFont("Gulim");

Step 5: Save the document.

presentation.SaveToFile("text.pptx", FileFormat.Pptx2007);

Full code:

using Spire.Presentation;
using System.Drawing;
namespace SetFont
{
    class Program
    {
        static void Main(string[] args)
        {
            //create PPT document

            presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
            presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;

            //append new shape
            IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle,
                new RectangleF(50, 70, 400, 50));

            //set the LineColor
            shape.ShapeStyle.LineColor.Color = Color.Black;

            //set the color and fill style
            shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
            shape.Fill.SolidColor.Color = Color.LightGray;
            shape.AppendTextFrame("This is a demo of text font and color.");
