---------------------------------
Hi,
Just for information: The image reading and writing works well with
twelvemonkeys lib: [https://github.com/haraldk/TwelveMonkeys]
from their code, it checks the Adobe segment at segment 0xFFEE first just after
reading the contents
> CMYK jpg file is not supported

> Hi,
> It seems that the attached cmyk jpg file is not supported. after writing back
> to jpg, it becomes black.
> read:
> bufferedImage = Imaging.getBufferedImage(filecontents);
> filecontents is the path to the image file.
> write:
> ByteArrayOutputStream bos = new ByteArrayOutputStream();
> ImageIO.write(bufferedImage, "jpg", bos);
> byte[] result = bos.toByteArray();
> System.out.println(result.length);
> ImageIO.write(bufferedImage, "JPG", outFile);
