这篇文章将介绍如何使用Spire.Presentation for Java添加、读取和删除PowerPoint幻灯片中的备注信息。

添加备注信息

import com.spire.presentation.*;

import java.io.FileWriter;

public class SpeakerNotes {
    public static void main(String[] args) throws Exception {
        //加载PowerPoint文档
        Presentation ppt = new Presentation();
        ppt.loadFromFile("Sample.pptx");

        //获取第一张幻灯片
        ISlide slide = ppt.getSlides().get(0);
        //添加备注幻灯片到第一张幻灯片
        NotesSlide notesSlide = slide.addNotesSlide();

        //添加备注标题
        ParagraphEx paragraph = new ParagraphEx();
        paragraph.setText("备注：");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);

        //添加第一项备注
        paragraph = new ParagraphEx();
        paragraph.setText("第一项备注；");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(1).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(1).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //添加第二项备注
        paragraph = new ParagraphEx();
        paragraph.setText("第二项备注；");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(2).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(2).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //添加第三项备注
        paragraph = new ParagraphEx();
        paragraph.setText("第三项备注；");
        notesSlide.getNotesTextFrame().getParagraphs().append(paragraph);
        notesSlide.getNotesTextFrame().getParagraphs().get(3).setBulletType(TextBulletType.NUMBERED);
        notesSlide.getNotesTextFrame().getParagraphs().get(3).setBulletStyle(NumberedBulletStyle.BULLET_ARABIC_PERIOD);

        //保存文档
        ppt.saveToFile("SpeakerNotes.pptx", FileFormat.PPTX_2013);
    }
}

读取备注信息

import com.spire.presentation.*;

import java.io.FileWriter;

public class SpeakerNotes {
    public static void main(String[] args) throws Exception {
        //加载PowerPoint文档
        Presentation ppt = new Presentation();
        ppt.loadFromFile("SpeakerNotes.pptx");

        //获取第一张幻灯片
        ISlide slide = ppt.getSlides().get(0);

        //获取幻灯片中的备注内容
        StringBuilder buffer = new StringBuilder();
        String notes = slide.getNotesSlide().getNotesTextFrame().getText();
        buffer.append(notes);

        //保存到文本文档
        FileWriter writer = new FileWriter("SpeakerNotes.txt");
        writer.write(buffer.toString());
        writer.flush();
        writer.close();
    }
}

删除备注信息

import com.spire.presentation.*;

import java.io.FileWriter;

public class SpeakerNotes {
    public static void main(String[] args) throws Exception {
        //加载PowerPoint文档
        Presentation ppt = new Presentation();
        ppt.loadFromFile("SpeakerNotes.pptx");

        //获取第一张幻灯片
        ISlide slide = ppt.getSlides().get(0);

        //删除幻灯片中所有备注
        slide.getNotesSlide().getNotesTextFrame().getParagraphs().clear();

        //保存文档
        ppt.saveToFile("DeleteSpeakerNotes.pptx", FileFormat.PPTX_2013);
    }
}
