Re: need help! (font width vs. font height)

[crusius_at_stanford . edu]

i "solved" my width problem by first setting a pixel size, loading a
glyph, and checking what was the resulting width. i then re-set the
pixel size, scaling it accordingly. it's ugly, but works fine. now i
have a few more problems:

1) once i have the font correctly scaled, i need to get "\baselineskip"
   from it. i tried face->size->metrics.height, but the value doesn't
   work (it's actually less than ascender-descender). i then used
   ascender-descender, which seems to work ok. is that right?

2) now i have the height for the lines. but i still need the offset
   from the bottom of the line and the baseline. i tried
   face->size->metrics.descender, but this value seems to fall short
   about 2 pixels from the "real" value. the letter "j", for example,
   extends 2 pixels below the line. (i am using cmtt10 for tests).

i guess i got (1) right. what about (2)???
