The functor realizes the transformation
![\[ R' = R_{max} \left(\frac{R}{R_{max}} \right)^{0.45} \qquad G' = G_{max} \left(\frac{G}{G_{max}} \right)^{0.45} \qquad B' = B_{max} \left(\frac{B}{B_{max}} \right)^{0.45} \]](form_8.png) 
By default,  . This default can be overridden in the constructor. If both source and target colors components are stored as
. This default can be overridden in the constructor. If both source and target colors components are stored as unsigned char, a look-up-table will be used to speed up the transformation.
