<h3>[ jsp ][ java ] 이미지 회전</h3>

90도 회전 시키기 샘플, 화질이 조금 떨어 지는 듯

BufferedImage oldImage = ImageIO.read(new FileInputStream(oldFile));

BufferedImage newImage = new                                   BufferedImage(oldImage.getHeight(),oldImage.getWidth(), oldImage.getType());

Graphics2D graphics = (Graphics2D) newImage.getGraphics();

graphics.rotate(Math.toRadians(90), newImage.getWidth() / 2, newImage.getHeight() / 2);

graphics.translate((newImage.getWidth() - oldImage.getWidth()) / 2, (newImage.getHeight() - oldImage.getHeight()) / 2);

graphics.drawImage(oldImage, 0, 0, oldImage.getWidth(), oldImage.getHeight(), null);

ImageIO.write(newImage, "JPG", new FileOutputStream(newFile));
