3、按比例缩放图片

public static void scale(String sourceImagePath, String targetImagePath, double scale)
            throws RuntimeException {
        try {
            Thumbnails.of(sourceImagePath).
            // scalingMode(ScalingMode.BICUBIC).
                    scale(scale). // 图片缩放scale%, 不能和size()一起使用
                    outputQuality(scale). // 图片质量压缩scale%
                    toFile(targetImagePath);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
