Setting range correction

The values of the background peak / text peak in the range correction 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 affect the reproduction of the background density and the values of
the text peak affect that of the text density.
