-mag:


When the vertical and horizontal sizes are converted and this is not specified, the value of \magstep written in the dvi file is used (Property Sheets->[Resolution]).

If \magstep is m, the size is 1.2^m times. A font resolution is searched for as a conversion that corresponds to this value.

The magstep values of 0, 1,..., 9 can be specified in the parameter file.  A "-1" indicates the default.  The "magstep half" specifies "-half=+".

Regardless of the current state, the default is always displayed on the [Resolution] in Property Sheets. (Erroneously setting a special magstep at start-up is prevented.) The current mag value can be found by "Help -> Information".
