- Yes. The slant was set when the fonts were produced. You can no more change
- the slant of the bitmaps than you could change the slant of the italic charac-
- ters on an IBM typeball.
-
- The \fontdimen parameter that measures slant reports the value that was used
- when the font was created. You can change it, but that just amounts to
- telling TeX to ignore reality and use THIS number.
-
- I suspect you are used to Postcript, which can create modified fonts on the
- fly from the basic outline descriptions. TeX fonts are bitmaps and are not
- modifiable. (Yes, there are TeX-to-Postscript DVI drivers, so you could have
- TeX use a "re-slanted" version of an outline-defined version of cmsl or cmti,
- if you had them. However, you would need some extrinsic mechanism for telling
- the printer (driver to tell the printer) to do this for you, and some mecha-
- nism for building an appropriate TFM file to tell TeX about the resulting
- character parameters. Just changing the slant would likely not give you
- decent results - the actual character width and height change when you "re-
- slant" them, so TeX would place them incorrectly.)
