Java如何將圖片新增到PPT幻燈片中？

在Java程式設計中，如何將圖片新增到PPT幻燈片中？

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將圖片新增到PPT幻燈片中的程式。

package com.yiibai;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.sl.usermodel.PictureData;
import org.apache.poi.util.IOUtils;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFPictureData;
import org.apache.poi.xslf.usermodel.XSLFPictureShape;
import org.apache.poi.xslf.usermodel.XSLFSlide;

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

        // creating a presentation
        XMLSlideShow ppt = new XMLSlideShow();

        // creating a slide in it
        XSLFSlide slide = ppt.createSlide();

        // reading an image
        File image = new File("dog.jpg");

        // converting it into a byte array
        byte[] picture = IOUtils.toByteArray(new FileInputStream(image));

        // adding the image to the presentation
        XSLFPictureData idx = ppt.addPicture(picture, PictureData.PictureType.PNG);

        // creating a slide with given picture on it
        XSLFPictureShape pic = slide.createPicture(idx);

        // creating a file object
        File file = new File("AddingimageToPPT.pptx");
        FileOutputStream out = new FileOutputStream(file);

        // saving the changes to a file
        ppt.write(out);

        System.out.println("image added successfully");
        out.close();
    }
}

執行上面範例程式碼，得到以下結果 -

image added successfully

這就建立一個PPT檔案:AddingimageToPPT.pptx了。
