用Java旋转图像

使用AffineTransform看一下这个例子：

有一些代码可以加载图像，这就是核心：

private Image image;AffineTransform identity = new AffineTransform();Graphics2D g2d = (Graphics2D)g;AffineTransform trans = new AffineTransform();trans.setTransform(identity);trans.rotate( Math.toRadians(45) );g2d.drawImage(image, trans, this);
