Manage Presentation Notes in Java

Aspose.Slides supports removing notes slides from a presentation. In this topic, we will introduce this new feature of removing Notes also adding notes style slides from any presentation.

Aspose.Slides for Java provides the feature of removing notes of any slide as well as add style to existing notes. Developers can remove notes in the following ways:

• Remove Notes of a Specific Slide of a presentation.
• Remove Notes of All Slides of 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.
