java - ImageIO.read illegal argument exception - raster bands/colour space components?

Question

Apologies for the somewhat vague title, I can't work out what the keywords are here. The setup's quite simple, I'm opening an image with

ImageIO.read(new File(filename));

This works for most files, however for one I get an IllegalArgumentException with the detail: "numbers of source Raster bands and source color space components do not match". This image was obtained via wget on a valid Flickr URL, and I've used other images obtained this way, so the method for obtaining images seems sound in principle. I'm not sure what's causing the exception.

A workaround would be more than acceptable - I'm not fussed with using ImageIO in particular, and the image looks fine visually. I just need to get it being read without Java freaking out!

Here's the image in question, in case it's of any use:

Answer 1

So I was having this same issue and found that the image was gray-scale and that the default ImageIO.read implementation was not figuring that out because the image metadata wasn't quite as expected. I wrote a work around that retries the load as 'BufferedImage.TYPE_BYTE_GRAY' if it fails the main load.

            Iterator<ImageReader> iter = ImageIO.getImageReaders(stream);

        Exception lastException = null;
        while (iter.hasNext()) {
            ImageReader reader = null;
            try {
                reader = (ImageReader)iter.next();
                ImageReadParam param = reader.getDefaultReadParam();
                reader.setInput(stream, true, true);
                Iterator<ImageTypeSpecifier> imageTypes = reader.getImageTypes(0);
                while (imageTypes.hasNext()) {
                    ImageTypeSpecifier imageTypeSpecifier = imageTypes.next();
                    int bufferedImageType = imageTypeSpecifier.getBufferedImageType();
                    if (bufferedImageType == BufferedImage.TYPE_BYTE_GRAY) {
                        param.setDestinationType(imageTypeSpecifier);
                        break;
                    }
                }
                bufferedImage = reader.read(0, param);
                if (null != bufferedImage) break;
            } catch (Exception e) {
                lastException = e;
            } finally {
                if (null != reader) reader.dispose();               
            }
        }
        // If you don't have an image at the end of all readers
        if (null == bufferedImage) {
            if (null != lastException) {
                throw lastException;
            }
        }
