PowerPoint 演示文稿是我们常用的办公软件之一。为了能够更加全面细致地展示要说明的内容，视频不失为一种很好的展示方式。本文将使用Java代码来演示如何插入视频到PowerPoint幻灯片，同时也将介绍提取视频以及设置视频播放模式的方法。
使用工具：Free Spire.Presentation for Java
测试环境：JDK 1.8.0、Intellij IDEA 2019
Jar包导入：
方式一：在E-iceblue中文官网上下载产品包，解压后在lib文件夹下找到Spire.Presentation.jar，然后手动将其导入IDEA。
方式二：在IDEA中创建Maven项目，然后在pom.xml下键入以下代码，最后点击“Import Changes”即可。
<repositories> <repository> <id>com.e-iceblue</id> <url>http://repo.e-iceblue.cn/repository/maven-public/</url> </repository> </repositories><dependencies> <dependency> <groupId>e-iceblue</groupId> <artifactId>spire.presentation.free</artifactId> <version>3.9.0</version> </dependency></dependencies>代码示例
示例一 插入视频到PowerPoint幻灯片
import com.spire.presentation.*;import javax.imageio.ImageIO;import java.awt.geom.Rectangle2D;import java.awt.image.BufferedImage;import java.io.File;public class InsertVideo { public static void main(String[] args) throws Exception { //加载PowerPoint示例文档 Presentation presentation = new Presentation(); presentation.loadFromFile("C:UsersTest1DesktopSample.pptx"); //获取第一张幻灯片 ISlide slide = presentation.getSlides().get(0); //插入视频到第一张幻灯片并设置封面图片 Rectangle2D.Double videoRect = new Rectangle2D.Double(150, 120, 400, 225); IVideo video = presentation.getSlides().get(0).getShapes().appendVideoMedia((new java.io.File("C:UsersTest1Desktopvideo.mp4")).getAbsolutePath(), videoRect); BufferedImage coverImage = ImageIO.read( new File("C:UsersTest1Desktopimage.png")); video.getPictureFill().getPicture().setEmbedImage(presentation.getImages().append(coverImage)); //保存结果文档 presentation.saveToFile("output/InsertVideo.pptx", FileFormat.PPTX_2010); presentation.dispose(); }}效果图：
示例二 提取PowerPoint幻灯片中已有的视频
import com.spire.presentation.IShape;import com.spire.presentation.ISlide;import com.spire.presentation.IVideo;import com.spire.presentation.Presentation;public class ExtractVideo { public static void main(String[] args) throws Exception { //实例化一个ppt对象并加载示例文档 Presentation ppt = new Presentation(); ppt.loadFromFile("C:UsersTest1DesktopInsertVideo.pptx"); //获取第一张幻灯片 ISlide slide = ppt.getSlides().get(0); IVideo video = null; for(int i = 0; i< slide.getShapes().getCount(); i++) { IShape shape = slide.getShapes().get(i); if ((shape instanceof IVideo)) { //保存视频 video = (IVideo) shape; video.getEmbeddedVideoData().saveToFile("output/ExtractVideo"+i+".mp4"); } } }}示例三 设置视频播放模式
import com.spire.presentation.FileFormat;import com.spire.presentation.IShape;import com.spire.presentation.ISlide;import com.spire.presentation.IVideo;import com.spire.presentation.Presentation;import com.spire.presentation.VideoPlayMode;public class PlayType { public static void main(String[] args) throws Exception { //实例化一个presentation对象并加载示例文档 Presentation presentation = new Presentation(); presentation.loadFromFile("C:UsersTest1DesktopInsertVideo.pptx"); //获取第一张幻灯片 ISlide slide = presentation.getSlides().get(0); IVideo video = null; for(int i = 0; i< slide.getShapes().getCount(); i++) { IShape shape = slide.getShapes().get(i); if ((shape instanceof IVideo)) { video = (IVideo) shape; //设置视频的播放模式为自动播放 //video.setPlayMode(VideoPlayMode.AUTO); //设置视频的播放模式为单击时播放 video.setPlayMode(VideoPlayMode.ON_CLICK); } } //保存PPT文档 presentation.saveToFile("output/单击播放.pptx", FileFormat.PPTX_2010); }}设置效果：
