Detailed Description

Class to define linear data mapping.

This class is used to define linear data mapping. This object defines a linear association between colors, transparencies and floating-point values. In other words, this association is defined by 2 functions F(c,v) and F(c,t):

         F(c,v)(V) = C (with c being a color and v being a value).
         F(t,v)(V) = T (with t being a transparency and v being a value).
   

F(c,v) and F(t,v) are linear, so only two values (v1 and v2), two associated transparencies(t1,t2) and two associated colors (c1 and c2) define these functions. For a given value vi, its color ci is determined by linear interpolation between (v1,c1) and (v2,c2). Idem for the transparencies. By default v1=0, v2=0, c1=(0,0,0) (black), c2=(1,1,1) (white), t1=t2=0.0 (opaque).
