Summary

The note information in the slide is only the specific content for the speaker to watch. When the speaker shows the slide, the note information can provide the speaker with explanation ideas and play an auxiliary role in explanation. This article will demonstrate how to operate the notes in the PPT slide through the Java program. The main points include:

1. Add notes
2. Modify note information
3. Read notes
4. Delete notes

Java code example

[Example 1] Add Note Information

import com.spire.presentation.*;

public class AddSpeakNotes {
    public static void main(String[] args) throws Exception{
        //Load PowerPoint File
        Presentation ppt = new Presentation();
        ppt.loadFromFile("sample.pptx");

        //Get the first slide
        ISlide slide = ppt.getSlides().get(2);
        //Add notes slide to first slide
        NotesSlide notesSlide = slide.addNotesSlide();

        //Add note title
        ParagraphEx paragraph = new ParagraphEx();
        String string = "Remarks:";
        paragraph.setText(string);
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //Add first note
        paragraph = new ParagraphEx();
        paragraph.setText("Remark of the first item;");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(1).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(1).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //Add second note
        paragraph = new ParagraphEx();
        paragraph.setText("The second remark;");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(2).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(2).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //Add third note
        paragraph = new ParagraphEx();
        paragraph.setText("The third remark;");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(3).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(3).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //Save document
        ppt.saveToFile("AddSpeakerNotes.pptx", FileFormat.PPTX_2013);
        ppt.dispose();
    }
}

Note adding effect:

[example 2] modify note information

import com.spire.presentation.*;

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

        //Get the specified slide
        ISlide slide = ppt.getSlides().get(2);

        //Modify the specified note information
        slide.getNotesSlide().getNotesTextFrame().getParagraphs().get(1).setText("New modified notes");
        slide.getNotesSlide().getNotesTextFrame().getParagraphs().get(2).setAlignment(TextAlignmentType.CENTER);
        slide.getNotesSlide().getNotesTextFrame().getParagraphs().get(2).setBulletStyle(NumberedBulletStyle.BULLET_ROMAN_UC_PAREN_RIGHT);

        //Save document
        ppt.saveToFile("modifySpeakerNotes.pptx",FileFormat.PPTX_2013);
        ppt.dispose();
    }
}

Note modification effect:

[example 3] read notes

import com.spire.presentation.*;

import java.io.FileWriter;

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

        //Get the specified slide
        ISlide slide = ppt.getSlides().get(2);

        //Get notes from slide
        StringBuilder builder = new StringBuilder();
        String notes = slide.getNotesSlide().getNotesTextFrame().getText();
        builder.append(notes);

        //Save to text document
        FileWriter writer = new FileWriter("ExtractSpeakerNotes.txt");
        writer.write(builder.toString());
        writer.flush();
        writer.close();
    }
}

Reading result of remark information:

[example 4] delete note information

import com.spire.presentation.*;

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

        //Get the specified slide
        ISlide slide = ppt.getSlides().get(2);

        //Delete notes
        slide.getNotesSlide().getNotesTextFrame().getParagraphs().get(0).getTextRanges().clear();//Delete notes in the specified paragraph
        //slide.getNotesSlide().getNotesTextFrame().getParagraphs().clear();//Delete all comments

        //Save document
        ppt.saveToFile("deleteSpeakerNotes.pptx",FileFormat.PPTX_2013);
        ppt.dispose();
    }
}
