I have recently (revision 11783) implemented plP_script_scale whose purpose is to consolidate in one place the calculations of scale factors for the font size and magnitude of the vertical offset associated with superscripts and subscripts. I now use this function for the superscript/subscript calculations for the Hershey fonts. plP_script_scale produces completely consistent magnitudes of the vertical offsets for subscripts and superscripts so this change corrects a long-standing (since prior to 1993) error in the subscript offset for Hershey fonts whose magnitude was 0.75 of the corresponding superscript offset. To check out what the new Hershey offsets look like for a variety of superscript/subscript levels, please run the python script,
examples/python/test_superscript_subscript.py -dev xwin I plan to convert all our remaining non-Hershey device drivers (starting with cairo and qt) to also use plP_script_scale.
