RAW CMYK Data in OpenCV

Hello Everyone. I"m aware that OpenCV cannot handle RAW image data , so i followed this guide to get it working: http://answers.opencv.org/question/58106/unable-to-open-raw-image-through-opencv/

However, it hasn't worked hehehe. Lemme explain the scenario: I'm dealing with 4 individual files, one for each channel (Cyan, Magenta, Yellow and Black). I can open the files individually on Photoshop ; i just need to inform Width, height and number of channels (and of course, files must have the extension .raw).

However, i tried to do the same with OpenCV using the topic i mentioned before and i couldn't get a working Preview. It seems that OpenCV doesn't know how many channels are available.

All files are 4 channel Grayscale images.

Is there something i can do to get OpenCV working with that ?

Thanks in advance.
