Find CMYK from background image

Lets pretend that I have an image placed in rhino (or grasshopper) and I have points placed on this image.

Is there some way to for those points to gather the CMYK values for that point on the image?

I would need doubles, but if someone knows a way to get strings that method is welcome also. Thanks in advance

Darnit, there's an oversight in our SDK cmyk colour type. It only exposes the CMY channels. I just added support for K as well, but this won't become available until the next release.

I had to copy-paste the entire functions to make it work.

This one deforms a mesh based on CMYK values.

No it won't. All of the Seattle coding team is currently tied up with releasing the new Rhino5 64-bit platform + SDK, and I'm sure as heck not going to check in any core code until the pressure's off :)
