String srcpath = "e:/pool.jpg" main(String[] args) ImageUtil util = beginTime = File file = Iterator readers = ImageIO.getImageReadersByFormatName("jpg" ImageReader reader = ImageInputStream iis = reader.setInput(iis, System.out.println("width:" + reader.getWidth(0 System.out.println("height:" + reader.getHeight(0 } endTime = System.out.println("使用[ImageReader]获取图片尺寸耗时：[" + (endTime - beginTime)+"]ms" beginTime = File file = FileInputStream is = is = } BufferedImage sourceImg = sourceImg = System.out.println("width:" + System.out.println("height:" + } endTime = System.out.println("使用[BufferedImage]获取图片尺寸耗时：[" + (endTime - beginTime)+"]ms" .srcpath = }

大家可以很容易明白...应该选择哪个方法了吧...
