在Java程式設計中,如何合併兩個PPT文件?

注意:需要存取網址:http://poi.apache.org/download.html , 下載一個Apache POI軟體包。這裡下載最新版本:poi-bin-3.17-20170915.tar.gz解壓並全部匯入 。

需要匯入全部包,如下圖所示 -

以下是使用Java合併兩個PPT文件的程式。

package com.yiibai;

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 = "aboutus1.pptx";
        String file2 = "aboutus2.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 = "aboutus12.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();
    }
}

執行上面範例程式碼,得到以下結果 -

Merging done successfully

這就建立一個PPT檔案:aboutus12.pptx了,如下所示 -
