本文将介绍如何使用Spire.Presentation for Java组件在PowerPoint文档中插入视频、提取视频以及设置视频的播放模式。

插入视频

import java.awt.Rectangle;
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;

public class InsertRadio {

    public static void main(String[] args) throws Exception {
	
	//实例化一个Presentation对象
	Presentation ppt = new Presentation();
	ppt.loadFromFile("E:\\演示文稿.pptx");

	//获取第一张幻灯片            
	ISlide slide = ppt.getSlides().get(0);
	
	//插入视频到第一张幻灯片		
	slide.getShapes().appendVideoMedia("E:\\视频.mp4", new Rectangle(300, 150, 300, 150));
	
	//保存文件
	ppt.saveToFile("E:\\插入视频.pptx", FileFormat.PPTX_2010);
	
    }
}

提取视频

import com.spire.presentation.IShape;
import com.spire.presentation.ISlide;
import com.spire.presentation.IVideo;
import com.spire.presentation.Presentation;

public class ExportVideo {

	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("E:\\插入视频.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("E:\\视频\\提取视频"+i+".mp4");
		    }
		}
	}
}

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("E:\\插入视频.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("E:\\单击播放.pptx", FileFormat.PPTX_2010);
	}
}
