*
* This class provides a linear remap between a min and a max value. Default is to do a linear
* stretch between the input connection's min and max, but the user can also define specific min
* and max. In the latter case, the input pixels outside the range will be clamped.
*
* If non-default min and max values are to be used, the min and max values must be set for all
* bands, otherwise the defaults will be used for all bands.
*
* The output scalar type is normalized double.
