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
