Detailed Description

Low level rescaler info used for rescaling.

Request linear rescaling from the input range [vmin, vmax] to the output range [omin, omax]. These ranges are initialized with Not-a-Number (NaN) values, which correspond to the following defaults:

• NaN in the input range means to use as input range the range of values effectively used in the input of the rescaler; unless usevtypelimits is true, in which case the whole range values of accommodated by the input type is used.
• NaN in the output range means to use the whole range of values accommodated by the output type.
