Setting range correction

The values of the background peak/text peak in the range correction at the Black Mode can be
switched to "varied" or "fixed" in the following codes.
If they are fixed, the range correction is performed with standard values.
The values of the background peak affects the reproduction of the background density, and the values
of the text peak affects that of the text density.
