Manage Presentation Notes in Java

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 example below:

// Instantiate a Presentation object that represents a presentation file
Presentation pres = new Presentation("presWithNotes.pptx");
try {
    // Removing notes of first slide
    INotesSlideManager mgr = pres.getSlides().get_Item(0).getNotesSlideManager();
    mgr.removeNotesSlide();

    // Saving presentation to disk
    pres.save("test.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Remove Notes from a Presentation

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

// Instantiate a Presentation object that represents a presentation file
Presentation pres = new Presentation("presWithNotes.pptx");
try {
    // Removing notes of all slides
    INotesSlideManager mgr = null;
    for (int i = 0; i < pres.getSlides().size(); i++) {
        mgr = pres.getSlides().get_Item(i).getNotesSlideManager();
        mgr.removeNotesSlide();
    }
    
    // Saving presentation to disk
    pres.save("test.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Add a Notes Style

getNotesStyle method 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 a Presentation object that represents a presentation file
Presentation pres = new Presentation("demo.pptx");
try {
    IMasterNotesSlide notesMaster = pres.getMasterNotesSlideManager().getMasterNotesSlide();
    
    if (notesMaster != null)
    {
        // Get MasterNotesSlide text style
        ITextStyle notesStyle = notesMaster.getNotesStyle();
    
        //Set symbol bullet for the first level paragraphs
        IParagraphFormat paragraphFormat = notesStyle.getLevel(0);
        paragraphFormat.getBullet().setType(BulletType.Symbol);
    }
    pres.save("NotesSlideWithNotesStyle.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

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 method 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.
