Description
A client has given us a set of PDF that have JPEG images that use the YCCK colour space. We also have quite a few PDF in our test suite. ICEpdf renders these images with a heavy green hue. The algorithms we to convert YCCK to RGB is from adobe but the converted image isn't very close to the benchmark.

I played around with several different variants of the YCCK to RGB algorithm with out much luck. To try and figure out what was going on I did some RGB colour grabs from the benchmark image and the image rendered in ICEpdf.
As a result I was able to tweak the ratios of YCCK colour components used to make the RGB colours. I still have to run this though qa but from my test set the results look pretty solid. Marking as resolved for now.
