PowerPoint 幻灯片中的备注信息是为使用者提供便利而设置的，该信息只对使用者可见。本文将向大家详细阐述如何通过Spire.Presentation for Java添加、读取和删除 PowerPoint 幻灯片中的备注信息。

注：编辑代码前，注意添加引用lib文件夹中的jar文件到程序(如下图)

示例1—添加备注到PPT：

import com.spire.presentation.*;

public class AddNotes {

public static void main(String[] args) throws Exception {

//加载PowerPoint文档

Presentation ppt = new Presentation();

ppt.loadFromFile("C:\Users\Administrator\Desktop\222.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:翠翠与爷爷孤苦伶仃，相依为命；");

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：天保和傩送与翠翠的曲折爱情；");

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：翠翠孤独终老；");

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);

}

}

备注添加效果：

示例2--读取PPT备注：

import com.spire.presentation.ISlide;

import com.spire.presentation.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();

}

}

读取结果：

示例3--删除备注

import com.spire.presentation.FileFormat;

import com.spire.presentation.ISlide;

import com.spire.presentation.Presentation;

public class DeleteNotes {

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);

}

}

删除结果：
