Apache POI PPT - 合并

简述

您可以使用 XMLSlideShow 类的 importContent() 方法合并多个演示文稿。下面给出了合并两个演示文稿的完整程序 -



import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;



import org.apache.poi.xslf.usermodel.XMLSlideShow;

import org.apache.poi.xslf.usermodel.XSLFSlide;



public class MergingMultiplePresentations {

   

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

      

      //creating empty presentation

      XMLSlideShow ppt = new XMLSlideShow();

      

      //taking the two presentations that are to be merged 

      String file1 = "presentation1.pptx";

      String file2 = "presentation2.pptx";

      String[] inputs = {file1, file2};

      

      for(String arg : inputs){

      

         FileInputStream inputstream = new FileInputStream(arg);

         XMLSlideShow src = new XMLSlideShow(inputstream);

         

         for(XSLFSlide srcSlide : src.getSlides()) {

         

            //merging the contents

            ppt.createSlide().importContent(srcSlide);

         }

      }

     

      String file3 = "combinedpresentation.pptx";

      

      //creating the file object

      FileOutputStream out = new FileOutputStream(file3);

      

      // saving the changes to a file

      ppt.write(out);

      System.out.println("Merging done successfully");

      out.close();

   }

}

将上述代码另存为 MergingMultiplePresentations.java，然后在命令提示符下编译并执行，如下所示 -



$javac MergingMultiplePresentations.java

$java MergingMultiplePresentations

它将编译并执行以生成以下输出 -



Merging done successfully
