Apache POI PPT - 合并( Merging)

您可以使用XMLSlideShow类的importContent()方法合并多个演示文稿。 以下是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();
   }
}

将上面的代码保存为MergingMultiplePresentations.java ,然后从命令提示符编译并执行它,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

以下快照显示了第一个演示文稿 -
