推荐答案

Fr 详细我们可以看一下http://www.randelshofer.ch/blog/2011/08/reading-cmyk-jpeg-images-with-java-imageio/

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 Advance image io 也解决了这个问题，但是安装在所有平台上很难维护.

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