Điều này là để chuyển đổi bất kỳ hình ảnh thành định dạng byte. Bạn có thể chuyển đổi định dạng jpg hoặc png thành định dạng byte và lưu vào cơ sở dữ liệu nếu được yêu cầu sử dụng Java. Kịch bản này cũng cung cấp thuộc tính hình ảnh như chiều rộng và chiều cao hình ảnh thực tế bằng pixel. Yuu có thể có được các thuộc tính hình ảnh với định dạng chiều rộng x chiều cao của định dạng hình chữ nhật trong một định dạng chuỗi.

Chuyển đổi hình ảnh thành Byte, lấy chiều rộng và chiều cao hình ảnh bằng Java
