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);
    }
