How to get the RGB Working Space from within a Filter Plug-In?
Within my Filter Plug-In I need to access the image's icc profile data. I know this can be accomplished with the according data structure 'iCCprofileData'. But what if there is no profile assigned to the image? Then iCCprofileData is NULL and the default should apply which is the 'RGB Working Space' (assuming the Plug-In works in RGB mode only, what it does). But how can I get to know what the 'RGB Working Space' is from within my Plug-In?
