C++/Changing color shceme.


I need to know how to change the RGB color scheme to CMYK color by using visual c++ 6 and GDI.

I need to draw objects using both color schemee.  

Yasanka , Thank you for your question.

Windows GDI does not support any color model other than RGB. GDI is a base technology not intended to serve all purposes.

I believe you will either have to write CMYK separation functions yourself, or buy them as an API library.
