Thanks, the composite image gives me a lot of what I need, but not  
everything! I need more control over how the different colour planes  
are merged together to form the final colour result (inter colour  
plane arithmetic to improve the appearance). The underlying colour  
planes (and their data) needs to remain immutable, I just want to  
create an interactive rendering of this multi plane data.

I also need to be able to add a (less clunky) user interface that  
makes the colour balancing more interactive.

The ColourThresholder may be worth investigating but that seems to  
modify the underlying data.

Regards -- Michael Ellis
