jpeg <-> byte 형 변환

JAVA에서 JPG와 Byte 간의 변환
1. JPG to Byte Array (1)
ByteArrayOutputStream out = new ByteArrayOutputStream(); ImageIO.write(image, "JPEG", out); byte[] imageBytes = out.toByteArray(); BufferedImage bi = ImageIO.read(new ByteArrayInputStream(imageBytes));

2. JPG to Byte Array (2)
File jpeg = new File("my.jpg"); byte[] bytes = new byte[jpeg.length()]; DataInputStream in = new DataInputStream(new FileInputStream(jpeg)); in.readFully(bytes); in.close(); // bytes will now contain contents of jpeg file // to convert back to a file: FileOutputStream out = new FileOutputStream("out.jpg"); out.write(bytes); out.close();
