Hi Andrew, thanks for your answer, too.
If I understand you right, JNI gives me access to the Kodak CMM¹s C interface. OK, that¹s interesting. But I assume that there is some overhead involved in converting a Java image buffer to a format the CMM interface understands. Anyway, I found the Kodak CMM API here http://docs.oracle.com/cd/E19695-01/802-2012/802-2012.pdf, is this the correct document for use with JNI? Could be a little more specific what you are suggesting in your second paragraph? I guess I understand what you mean, but I¹d like to know the steps that are neccessary to do to achieve the goal. Let¹s say I have a source RGB image in AdobeRGB colorspace and want to convert it to a CMYK colorspace, then do a softproof from that CMYK colorspace to the display colorspace, that is represented by a custom ICC profile. Could you briefly outline the last part (CMYK ‹> display) using your kludgy workaround in Java?
