    javax.imageio.ImageIO的异常

    代码:

    String basePath = Thread.currentThread().getContextClassLoader().getResource("").getPath();
    Thumbnails.of(new File("C:/test/test.jpg"))
    		.size(200, 200).watermark(Positions.BOTTOM_RIGHT,ImageIO.read(new File(basePath + "/watermark.jpg")),0.25f).outputQuality(0.8f)
    		.toFile("C:/test/testnew.jpg");
    

    错误信息:

    Exception in thread "main" javax.imageio.IIOException: Can't read input file!
    	at javax.imageio.ImageIO.read(Unknown Source)
    	at com.tbx.o2o.util.ImageUtil.main(ImageUtil.java:18)
    
    

    原因:

    路径获取错误

    /D:/Javaee%20_workspaces/o2o/target/classes/  
    //出现%20的错误
    

    解决方法:

    basePath=URLDecoder.decode(basePath,"utf-8");
    

    添加以后:

    /D:/Javaee _workspaces/o2o/target/classes/
    正常,异常排除

    软件包 javax.imageio 的描述
    Java Image I/O API 的主要包。
    
    使用 ImageIO 类的静态方法可以执行许多常见的图像 I/O 操作。
    
    此包包含一些基本类和接口,有的用来描述图像文件内容(包括元数据和缩略图)(IIOImage);有的用来控制图像读取过程(ImageReader、ImageReadParam 和 ImageTypeSpecifier)和控制图像写入过程(ImageWriter 和 ImageWriteParam);还有的用来执行格式之间的代码转换 (ImageTranscoder) 和报告错误 (IIOException)。
    
    javax.imageio 的所有实现都提供以下标准图像格式插件:
    
    读取 写入
    
    JPEG 是 是
    
    PNG 是 是
    
    BMP 是 是
    
    WBMP 是 是
    
    GIF 是 否
    1、读入的三种方法 
    public static BufferedImage read(File input)
    
    File file = new File("/Users/xixi/Documents/aaa.png");
    BufferedImage bu = ImageIO.read(file);
    1
    2
    public static BufferedImage read(InputStream input)
    
    public static BufferedImage read(ImageInputStream stream)
    
    2、RenderedImage接口的子类是BufferedImage,因此在这里可以直接出传入BufferedImage的实例化对象,将BufferedImage对象直接写出指定输出流
    
    public static boolean write(RenderedImage im,String formatName,File output)
    
    public static boolean write(RenderedImage im, String formatName,OutputStream output)
    
    public static boolean write(RenderedImage im, String formatName,ImageOutputStream output)
    
    复制图片代码
    
    public class Test {
        public static void main(String[] args) {
            File out = new File("/Users/wangjue/DownLoads/1.jpg");
            //将图片写入ImageIO流
            try {
                BufferedImage img = ImageIO.read(out);
            //将图片写出到指定位置(复制图片)
                OutputStream ops = new FileOutputStream(new File("/Users/wangjue/DownLoads/1(1).jpg"));
                ImageIO.write(img, "jpg", ops);         
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
    }
