Hi Graham,
I tried to display the RGB spectrum as an image in the view. How can
I pick
particular pixel color from that image. Does it make sense?

C'mon, get real. No-one's going to write your code for you. If you
can't
find a free class somewhere, subclass NSView yourself. A location
<--> RGB
mapping is pretty easy.

Hi Graham,
Yes. But do you have any other ways to handle this.
I want something like this
I could be able to pick the color from the spectrum band and could
change
the Alpha (This I can manage to some extent, Immediately I need to
handle
the picking colour from the spectrum.)
Regards
Mustafa
