INTERPOLATION
-------------
   
The colours of a field are interpolated
between the two field limits.
The Interpolation :
item indicates LINear or LOGarithmic 
interpolation.
RGB : all three components are 
interpolated LIN or LOG.
HLS : Luminance only can be 
interpolated LOG.

When a slider (R,G,B,H,L, or S) is 
changed, the color table field is 
instantly updated according to LIN or 
LOG mode.
The field limits are given by 'Field 
number:', they can be changed (keybord), 
the two arrows show both region limits
on the colour table.

information.
