Workaround Description:use org.icepdf.core.cmyk.disableICCProfile=true to improve performance
Description
A client has sent in a PDF that has a medium sized image (2496x3216) and corresponding image mask. The images however use a n ICC color profile which has very expensive colour look ups.
When working with ICC color profiles for CMYK pallets I found that the Java Implementation was too slow for doing image lookups. I think it's time to revisit this issue both for ICCBase and DeviceCMYK colour spaces. There is a good chance we could create a local lookup cache that would improve performance as well as getting better colour accuracy.
