I was trying to use the Math Times Pro 2 fonts in ConTeXt MKIV. This
Type1 font contains a map file, a set of pfb files and the corresponding
tfm files. I was managed to write a .lfg file and a type-imp-xxx file,
but here's my problem.
I don't have the fonts, so I cannot describe the exact method. But see
below and also have a look at Section 5 of
https://www.tug.org/TUGboat/tb30-2/tb95mahajan-cmath.pdf The description
is old, and some of the file locations have changes, but the basic
infrastructure is still the same.
The font comes with three different sizes, the virtual fonts in my .lfg
file look like:
===================================================================
virtuals = {
["mtpro06a-regular"] = {
{ name = "file:texgyretermes-regular.otf", features =
"virtualmath", main = true },
{ name = "mt2mif.tfm", vector = "mtpro2-mi",
skewchar=0x7F },
[...]
},
The vectors mptpro2-mi etc are not defined. Look at math-ttv.lua for a
list of predefined vectors (mapping type1 fonts to unicode symbols. It is
quite likely that the mtpro fonts would follow the "standard" mappings; if
not, you will need to create an approrpriate mapping for each font. This
is not difficult (just monotonous).
===================================================================
I guess the suffixes "f" "s" and "t" may correspond to "five" "seven"
and "ten", but that's
not important. I could use one of them as the virtual font in the
typescript:
Once this is done, rest of the typescript should work. It may be a good
idea to try to see if you can get roman letters from mtpro.
