Manage Presentation Notes in .NET

Overview

Aspose.Slides supports removing notes slides from a presentation. In this topic, we will introduce this feature, including how to remove notes and how to apply a style to notes slides in a presentation. Aspose.Slides allows you to remove notes from any slide and also apply styling to existing notes. Developers can remove notes in the following ways:

  • Remove notes from a specific slide in a presentation.
  • Remove notes from all slides in a presentation.

Remove Notes from a Slide

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

// Instantiate a Presentation object that represents a presentation file 
Presentation presentation = new Presentation(dataDir + "AccessSlides.pptx");

// Removing notes of first slide
INotesSlideManager mgr = presentation.Slides[0].NotesSlideManager;
mgr.RemoveNotesSlide();

// Save presentation to disk
presentation.Save(dataDir + "RemoveNotesAtSpecificSlide_out.pptx", SaveFormat.Pptx);

Remove Notes from All Slides

Notes of all the slides of a presentation could be removed as shown in the example below:

// Instantiate a Presentation object that represents a presentation file 
Presentation presentation = new Presentation("AccessSlides.pptx");

// Removing notes of all slides
INotesSlideManager mgr = null;
for (int i = 0; i < presentation.Slides.Count; i++)
{
    mgr = presentation.Slides[i].NotesSlideManager;
    mgr.RemoveNotesSlide();
}
// Save presentation to disk
presentation.Save("RemoveNotesFromAllSlides_out.pptx", SaveFormat.Pptx);

Add a Notes Style

NotesStyle property has been added to IMasterNotesSlide interface and MasterNotesSlide class respectively. This property specifies the style of a notes text.  The implementation is demonstrated in the example below.

// Instantiate Presentation class that represents the presentation file
using (Presentation presentation = new Presentation("AccessSlides.pptx"))
{
    IMasterNotesSlide notesMaster = presentation.MasterNotesSlideManager.MasterNotesSlide;

    if (notesMaster != null)
    {
        // Get MasterNotesSlide text style
        ITextStyle notesStyle = notesMaster.NotesStyle;

        //Set symbol bullet for the first level paragraphs
        IParagraphFormat paragraphFormat = notesStyle.GetLevel(0);
        paragraphFormat.Bullet.Type = BulletType.Symbol;
    }

    // Save the PPTX file to the Disk
    presentation.Save("AddNotesSlideWithNotesStyle_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

}

FAQ

Which API entity provides access to the notes of a specific slide?

Notes are accessed through the slide’s notes manager: the slide has a NotesSlideManager and a property that returns the notes object, or null if there are no notes.

Are there differences in notes support across the PowerPoint versions the library works with?

The library targets a broad range of Microsoft PowerPoint formats (97–newer) and ODP; notes are supported within these formats without depending on an installed copy of PowerPoint.
