Java使用POI对Excel进行基本操作(4)-Excel中绘制图片

1、在Excel中绘制图片

    public static void main(String[] args) throws Exception {
        // 定义一个工作簿
        Workbook workbook = new XSSFWorkbook();
        // 创建一个sheet页
        Sheet sheet = workbook.createSheet("第一个sheet页");
        FileInputStream fis = new FileInputStream("E:\\桌面壁纸\\yoona头像.jpg");
        // 向Excel中添加一张图片，并返回改图片在Excel中的图片集中的索引
        int pictureIndex = ((XSSFWorkbook) workbook).addPicture(fis, Workbook.PICTURE_TYPE_JPEG);
        // 获取工作簿的绘图工具类
        CreationHelper creationHelper = workbook.getCreationHelper();
        // 创建一个绘图对象
        Drawing<?> drawingPatriarch = sheet.createDrawingPatriarch();
        // 创建锚点，设置图片坐标
        ClientAnchor clientAnchor = creationHelper.createClientAnchor();
        clientAnchor.setRow1(0);
        clientAnchor.setCol1(0);
        // 创建图片
        Picture picture = drawingPatriarch.createPicture(clientAnchor, pictureIndex);
        picture.resize();

        FileOutputStream fileOutputStream = new FileOutputStream("D:\\测试Excel中绘制图片.xlsx");
        workbook.write(fileOutputStream);
        fileOutputStream.close();
    }

结果如下：
