Constructor Detail

LinearInterpolator

public LinearInterpolator(double _dblMin1,
                          double _dblMax1,
                          double _dblMin2,
                          double _dblMax2)

Constructor: two ranges of double values are presented. Interpolation can be evoked for any number from the one range, to the other range, in either direction. Extrapolation from/to outside the ranges is permissible (no clamping)

Parameters:

_dblMin1 - minimum of first range

_dblMax1 - maximum of first range

_dblMin2 - minimum of second range

_dblMax2 - maximum of second range
