-e:
The vertical and horizontal sizes are magnified or reduced. A variable-size font like a Windows TrueType font is magnified and reduced accordingly. The vertical and horizontal sizes are converted to 1/1000 of the set value (Property Sheets->[Resolution]). This parameter takes a positive integer or 0.
0 means to reset this function.
When magnifying or reducing to match "-e:" for all of the fonts, -varf: is specified.
