Java读取不同类型的图像格式jpg，tif，gif，png

问题描述：

我正在尝试阅读一些图像文件jpg，tif，gif，png，需要保存文件和创建图标。
我收到 UnsupportedTypeException 。

I am trying to read some image files jpg, tif, gif, png and need to save files and create icons. And i am getting UnsupportedTypeException.

ImageIO.read(file);

如果我使用以下行，如前面的形式所述。

If i use following line, as earlier discuss in form.

BufferedImage img = JPEGCodec.createJPEGDecoder(inputStream).decodeAsBufferedImage();

我得到 JPEGCodec 找不到符号。

我使用的是netbean 7.0.1。我还添加了jai-imageio.jar。

Fr detail we can see the like http://www.randelshofer.ch/blog/2011/08/reading-cmyk-jpeg-images-with-java-imageio/

Image img = null;
ImageInputStream iis = new FileImageInputStream(file);
try {
    for (Iterator<ImageReader> i = ImageIO.getImageReaders(iis);
         img == null && i.hasNext(); ) {
        ImageReader r = i.next();
        try {
            r.setInput(iis);
            img = r.read(0);
        } catch (IOException e) {}
    }
} finally {
    iis.close();
}
return img;

Java高级图像io也解决了这个问题，但很难维护安装在所有平台上。

Java advance image io also solve the problem, but its hard to maintain to install on all plateform.
