S.P.Q.Rahtz@ecs.soton.ac.uk (Sebastian Rahtz) (06/24/91)
Is there a person of great wizardry out there who has read and
understood all of Appendix G in the TeX book? I am trying to install
the Lucida maths fonts in place of cmmi, cmex and cmsy. cmmi and cmex
are easy (haha) - I have virtual fonts which put the characters in the
right places, and my guesses at the missing fontdimens are OK for a
trial. But the maths extension fonts in anothe matter. I offer you
three curious facts
1) all the characters in the font seem to hang below the baseline.
why?
2) did you know that when you look at the fontdimen parameters for
cmex10, they are different from those listed in the .TFM file?
dont ask me how this comes about! a number 14 is listed in my run
of TeX, but the TFM file only has 13...
3) when I do maths typesetting with Lucida, the delimiters are
wrong, and always appear in the small sizes.
is this a question of successors and extensions?if so, I have to add
these into my vpl file with VARCHAR and NEXTLARGER? or is it much
nastier?
any words of wisdom on these thorny problems would be much
appreciated. of course, what I would realy like to hear is if anyone
else has a set of TFM files for Lucida Math already!
at the end of the week, I will `publish' my Lucida Math material for
anyone who wants it.

PS bloody Adobe and /or Knuth. Adobe give metrics in units where 1000
is the design size of the character. some of the metrics in the
extension font are larger than 2048, so VPtoVF refuses to accept them.
sigh.
