Re: colormaps

Hi Kathy Lee,
 
Both the grey scale color map (default when you just addMap
a ScalarMap to Display.RGB) and the color spectrum color map
(when you pass the ScalarMap to LabeledRGBWidget) have 256
entries.  So the difference in resolution is (hopefully)
just color perception.
 
> And how do you use the widget to control color?
 
Clicking the right or center mouse button switches the left
button between red, green and blue (and alpha, for a
LabeledRGBAWidget).
 
Cheers,
Bill
