            Description

            The cmyk colour conversion to rgb algorithm has always produced image that were a little dark when compared to acrobat. During the image refactoring work there was a consolidation as to which cmyk algorirthms where being used add a a result the black levels are a lot closer then in 4.x.

            I'm going to revert our fudge value but also include a system property org.icepdf.core.cmyk.black=255. Values greater than 255 will lighten an image and values less than 255 will darken the image.
