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);
