Add Speaker Notes in PowerPoint in Java

The following are the main steps to add speaker notes to a PowerPoint document:

  • Create a Presentation instance and load a PowerPoint document using Presentation.loadFromFile() method.
  • Get the slide that you want to add speaker notes to using Presentation.getSlides().get(slideIndex) method.
  • Add a notes slide to the slide using ISlide.addNotesSlides() method.
  • Create a ParagraphEx instance.
  • Set text for the paragraph through ParagraphEx.setText() method, then append the paragraph to the notes slide using NotesSlide.getNotesTextFrame().getParagraphs().append() method.
  • Save the result document using Presentation.saveToFile() method.
  • Java
import com.spire.presentation.*;

public class AddSpeakerNotes {
    public static void main(String []args) throws Exception {
        //Load a PowerPoint document
        Presentation ppt = new Presentation();
        ppt.loadFromFile("Sample.pptx");

        //Get the first slide
        ISlide slide = ppt.getSlides().get(0);
        //Add a notes slide
        NotesSlide notesSlide = slide.addNotesSlide();

        //Add a paragraph to the notes slide
        ParagraphEx paragraph = new ParagraphEx();
        paragraph.setText("Tips for making effective presentations:");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //Add a paragraph to the notes slide
        paragraph = new ParagraphEx();
        paragraph.setText("Use the slide master feature to create a consistent and simple design template.");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //Add a paragraph to the notes slide
        paragraph = new ParagraphEx();
        paragraph.setText("Simplify and limit the number of words on each screen.");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //Add a paragraph to the notes slide
        paragraph = new ParagraphEx();
        paragraph.setText("Use contrasting colors for text and background.");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //Set the bullet type and bullet style for specific paragraphs on the notes slide 
        for (int i = 1; i < notesSlide.getNotesTextFrame().getParagraphs().getCount();i++)
        {
            notesSlide.getNotesTextFrame().getParagraphs().get(i).setBulletType(TextBulletType.NUMBERED);
            notesSlide.getNotesTextFrame().getParagraphs().get(i).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);
        }

        //Save the result document
        ppt.saveToFile("SpeakerNotes.pptx", FileFormat.PPTX_2013);
    }
