Well that much I know. And I also know that many NS/UI-things (which use 
Objective-C) often have a CF-counterpart, which uses plain C and often these 
are toll-free bridged. The latter kind is typically used when one needs more 
options or finer control. (E.g. NSDictionary / CFDictionary).

But what is the story behind NS/UIView relative to CIImage, CGImage? When to 
use what? What are the relevant advantages? 

I would really like to get some link to some documentation, which explains 
these questions.

Kind regards,

Gerriet.
