Presentation Header and Footer

Aspose.Slides for .NET provides the feature for managing headers and footers inside presentation slides. These are in fact managed on the presentation master level.

Manage Header and Footer Text

Notes of some specific slide could be updated as shown in the example below:

// Load Presentation
Presentation pres = new Presentation("headerTest.pptx");

// Setting Footer
pres.HeaderFooterManager.SetAllFootersText("My Footer text");
pres.HeaderFooterManager.SetAllFootersVisibility(true);

// Access and Update Header
IMasterNotesSlide masterNotesSlide = pres.MasterNotesSlideManager.MasterNotesSlide;
if (null != masterNotesSlide)
{
	UpdateHeaderFooterText(masterNotesSlide);
}

// Save presentation
pres.Save("HeaderFooterJava.pptx", SaveFormat.Pptx);

// Method to set Header/Footer Text
public static void UpdateHeaderFooterText(IBaseSlide master)
{
    foreach (IShape shape in master.Shapes)
    {
        if (shape.Placeholder != null)
        {
            if (shape.Placeholder.Type == PlaceholderType.Header)
            {
                ((IAutoShape)shape).TextFrame.Text = "HI there new header";
            }
        }
    }
}

  • Set text to notes slide Header placeholder.
  • Set text to notes slide Date-time placeholder.
  • Write the modified presentation file.

Code Snippet provided in the below Example.

using (Presentation presentation = new Presentation("presentation.pptx"))
{
	// Change Header and Footer settings for notes master and all notes slides
	IMasterNotesSlide masterNotesSlide = presentation.MasterNotesSlideManager.MasterNotesSlide;
	if (masterNotesSlide != null)
	{
		IMasterNotesSlideHeaderFooterManager headerFooterManager = masterNotesSlide.HeaderFooterManager;

		headerFooterManager.SetHeaderAndChildHeadersVisibility(true); // make the master notes slide and all child Footer placeholders visible
		headerFooterManager.SetFooterAndChildFootersVisibility(true); // make the master notes slide and all child Header placeholders visible
		headerFooterManager.SetSlideNumberAndChildSlideNumbersVisibility(true); // make the master notes slide and all child SlideNumber placeholders visible
		headerFooterManager.SetDateTimeAndChildDateTimesVisibility(true); // make the master notes slide and all child Date and time placeholders visible

		headerFooterManager.SetHeaderAndChildHeadersText("Header text"); // set text to master notes slide and all child Header placeholders
		headerFooterManager.SetFooterAndChildFootersText("Footer text"); // set text to master notes slide and all child Footer placeholders
		headerFooterManager.SetDateTimeAndChildDateTimesText("Date and time text"); // set text to master notes slide and all child Date and time placeholders
	}

	// Change Header and Footer settings for first notes slide only
	INotesSlide notesSlide = presentation.Slides[0].NotesSlideManager.NotesSlide;
	if (notesSlide != null)
	{
		INotesSlideHeaderFooterManager headerFooterManager = notesSlide.HeaderFooterManager;
		if (!headerFooterManager.IsHeaderVisible)
			headerFooterManager.SetHeaderVisibility(true); // make this notes slide Header placeholder visible

		if (!headerFooterManager.IsFooterVisible)
			headerFooterManager.SetFooterVisibility(true); // make this notes slide Footer placeholder visible

		if (!headerFooterManager.IsSlideNumberVisible)
			headerFooterManager.SetSlideNumberVisibility(true); // make this notes slide SlideNumber placeholder visible

		if (!headerFooterManager.IsDateTimeVisible)
			headerFooterManager.SetDateTimeVisibility(true); // make this notes slide Date-time placeholder visible

		headerFooterManager.SetHeaderText("New header text"); // set text to notes slide Header placeholder
		headerFooterManager.SetFooterText("New footer text"); // set text to notes slide Footer placeholder
		headerFooterManager.SetDateTimeText("New date and time text"); // set text to notes slide Date-time placeholder
	}
	presentation.Save("testresult.pptx",SaveFormat.Pptx);
}
		
 }

FAQ

Can I add a “header” to regular slides?

In PowerPoint, “Header” exists only for notes and handouts; on regular slides, the supported elements are the footer, date/time, and slide number. In Aspose.Slides this matches the same limitations: header only for Notes/Handout, and on slides—Footer/DateTime/SlideNumber.

What if the layout doesn’t contain a footer area—can I “turn on” its visibility?

Yes. Check the visibility via the header/footer manager and enable it if needed. These API indicators and methods are designed for cases when the placeholder is missing or hidden.

How do I make the slide number start from a value other than 1?

Set the presentation’s first slide number; after that, all numbering is recalculated. For example, you can start at 0 or 10, and hide the number on the title slide.

What happens to headers/footers when exporting to PDF/images/HTML?

They are rendered as regular text elements of the presentation. That is, if the elements are visible on slides/notes pages, they will also appear in the output format along with the rest of the content.
