Java使用POI對Excel進行基本操作(4)-Excel中繪制圖片

1、在Excel中繪制圖片

    public static void main(String[] args) throws Exception {
        // 定義一個工作簿
        Workbook workbook = new XSSFWorkbook();
        // 創建一個sheet頁
        Sheet sheet = workbook.createSheet("第一個sheet頁");
        FileInputStream fis = new FileInputStream("E:\\桌面壁紙\\yoona頭像.jpg");
        // 向Excel中添加一張圖片，並返回改圖片在Excel中的圖片集中的索引
        int pictureIndex = ((XSSFWorkbook) workbook).addPicture(fis, Workbook.PICTURE_TYPE_JPEG);
        // 獲取工作簿的繪圖工具類
        CreationHelper creationHelper = workbook.getCreationHelper();
        // 創建一個繪圖對象
        Drawing<?> drawingPatriarch = sheet.createDrawingPatriarch();
        // 創建錨點，設置圖片坐標
        ClientAnchor clientAnchor = creationHelper.createClientAnchor();
        clientAnchor.setRow1(0);
        clientAnchor.setCol1(0);
        // 創建圖片
        Picture picture = drawingPatriarch.createPicture(clientAnchor, pictureIndex);
        picture.resize();

        FileOutputStream fileOutputStream = new FileOutputStream("D:\\測試Excel中繪制圖片.xlsx");
        workbook.write(fileOutputStream);
        fileOutputStream.close();
    }

結果如下：
