Re: [NTG-context] Math setup with Times (Termes)
Thank you everybody very much, esp. Mojca! You almost saved my life! )
In spite of previously said, I don't like mixing Termes with Times New
Roman, because e.g. "M" in math looks rather like bold "M" in the text.
But I made a hack which works for me:
{ name = "timesi.ttf", vector = "tex-mi-txpx2", skewchar=0x7F },
I just replaced texgyretermes-italic.otf with timesi.ttf.
Unfortunatelly, I cannot modify the first line too, because some greek
letters are missed then, but I believe one day I could manage this )
mathematics.make_font ( "tx-math", {
{ name = "texgyretermes-regular.otf", features = "virtualmath",
main = true },
{ name = "rtxr.tfm", vector = "tex-mr" } ,
{ name = "rtxmi.tfm", vector = "tex-mi-txpx1", skewchar=0x7F },
{ name = "timesi.ttf", vector = "tex-mi-txpx2", skewchar=0x7F },
{ name = "txsy.tfm", vector = "tex-sy", skewchar=0x30, parameters =
true } ,
{ name = "txex.tfm", vector = "tex-ex", extension = true } ,
{ name = "txsya.tfm", vector = "tex-ma" },
{ name = "txsyb.tfm", vector = "tex-mb" },
} )
Perfect for the moment! Thanks again!

Re: [NTG-context] Math setup with Times (Termes)
Hello Hans, And I'd prefer italic latin letters to be taken from it, not from Termes. well, then you have to write your own vectors ... support for all those platform fonts is not on the agenda (at least not on mine) ... of course open type math fonts on platfotms are supported. OK, I will be completely happy if I have Termes letters in formulas. They are indistinguishable from Times New Roman in this case. P.S. I could write vectors, if someone explained me how to do it ;) Vyatcheslav ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

You can take a look at

\font\testone=rtxmi.tfm \testone

\stoptext
Then two copies of tex-mi in math-vfu are needed (some other name has
to be assigned). One where only red characters are used and the other
one where all the others are left (just comment out the rest that's
not needed). You probably need to map g, v, w, y, ... separately to
the math italic unicode range (that's not done in current tex-mi).
You may visually check if that's consistent with LM font in the third row.

(Thinking one step further ... one could take all the greek letters
from TeX Gyre as well, though I'm not 100% sure ... it could be that
there is some metric information present in these tfm files that's
missing in otf fonts.)

Oh, I see it now. At this point:
fonts.vf.math.set_letters(fonts.enc.math, "tex-mi", 0x1D434, 0x1D44E)
the letters from tex-mi are copied to math italic, but in case of
txfonts and the chosen subset of glyphs this region is empty, so
ConTeXt most probably just falls back to "normal a" from the main
regular font, but those characters should come from the italic font
instead (I don't know if additional metrics are needed or not).
I tried to do the following for example:
fonts.enc.math["tex-mi2"] = {
}
-- now that all other vectors are defined ...
fonts.vf.math.set_letters(fonts.enc.math, "tex-mi", 0x1D434, 0x1D44E)
fonts.vf.math.set_letters(fonts.enc.math, "tex-mi2", 0x1D434, 0x1D44E)
mathematics.make_font ( "tx-math", {
{ name = "texgyretermes-regular.otf", features = "virtualmath",
main = true },
{ name = "rtxr.tfm", vector = "tex-mr" } ,
{ name = "rtxmi.tfm", vector = "tex-mi", skewchar=0x7F },
{ name = "texgyretermes-italic.otf", vector = "tex-mi2", skewchar=0x7F },
{ name = "txsy.tfm", vector = "tex-sy", skewchar=0x30, parameters = true } ,
{ name = "txex.tfm", vector = "tex-ex", extension = true } ,
{ name = "txsya.tfm", vector = "tex-ma" },
{ name = "txsyb.tfm", vector = "tex-mb" },
} )
I now get italic math (but roman h for example). So this needs to be
fixed a bit, but it's the right direction at least. (Though it might
be better to use generic names like "regular" or "italic" for name= in
case that users try to use some other times-like base font for
example.)

Then use a font which is in the map file and has also a font with the same name.

Does that work for you (it doesn't here, but as I said ... I have very
bad karma).
txmi is not in that map file since txmi.vf is used instead.
But at least the vf file is almost-readable.
(MAPFONT D 0
(FONTNAME rtxmi)
(MAPFONT D 1
(FONTNAME rtxptmri)

What are we talking about? Do you mean the old virtual fonts (.vf

No vf is fine, but ... can mkiv (at least in theory) read vf files?
How does one disassemble vf files otherwise? vftosomething? I have
absolutely no idea what's in there. If mkiv can read vf, I would at
least cheat in such a way that I would read the font with mkiv, print
out the contents (what slot points to what place) and then rearrange
the contents in some more primitive format that mkiv could be
interpreting in the same way as all the other math fonts.

Something like \mr could work in mkiv, but I don't think that it does.
(But should be easy to fix.)

How do you expect it to work? Just return italic cyrilic letters?
Maybe Taco knows it better - do "any letters from the font" need to
have extra parameters to be usable with math? You can of course use
$\text{\it some cyrilic here}$
at any time.

tfm files work without map files at all.
> but it's far beyond my understanding to fix something in it.
There is one line that definitely needs to be fixed, but I have no idea how.
Here:
mathematics.make_font ( "tx-math", {
{ name = "texgyretermes-regular.otf", features = "virtualmath",
main = true },
{ name = "rtxr.tfm", vector = "tex-mr" } ,
this line:
{ name = "rtxmi.tfm", vector = "tex-mi", skewchar=0x7F },
might need to become:
{ name = "txmi.tfm", vector = "tex-mi", skewchar=0x7F },
{ name = "txsy.tfm", vector = "tex-sy", skewchar=0x30, parameters = true } ,
{ name = "txex.tfm", vector = "tex-ex", extension = true } ,
{ name = "txsya.tfm", vector = "tex-ma" },
{ name = "txsyb.tfm", vector = "tex-mb" },
} )
But if I change that then nothing happens. Maybe the reason is that
MKIV does not read map files and consequently has no idea what to do
with txmi(.tfm) that comes from rtxmi.pfb, or at least one would need
to rewrite "tex-mi" for times.
I don't know yet how to do it (I don't know how luatex reads in pfb
files with characters with non-standard names). This support is
definitely missing from the ConTeXt core and needs both a tiny help
from Hans' hands and someone writing a vector (or some other trick to
make the original tfm file work).

[NTG-context] Math setup with Times (Termes)
Hello Gurus,
Please, please, please! I need your help badly.
The problem is with math font setup. If I use default math font, two
problems arise:
1) Greek letters are slanted, while they supposed by our standards to be
straight.
2) Cyrillic does not work in math, while some indexes are in Ukrainian.
I also try to setup Times New Roman (from Windows) to replace default
math font. This would be perfect solution for me, but I've lost completely.
For my current point, I found that my TimesNR typescript behaves just
like Gyre-Termes, so you can experiment on the latter (without need of
Windows). This is my minimal example (see attachment also):
\usetypescript[termes]\setupbodyfont[termes, 14pt]
\starttext
Така система рівнянь має вигляд:
$это мат. текст this this math text$
\startformula\left\{ \matrix{
2 = a \cdot {2^2} + b \cdot 2 + c; \hfill \cr
1 = a \cdot {3^2} + b \cdot 3 + c; \hfill \cr
2a \cdot 2 + b = 0. \hfill \cr} \right.\stopformula
Вирішуючи цю систему рівнянь, можна отримати
всі три коефіцієнти: $c = - 2$; $a = - 1$; $b = 4$.
\stoptext
The main problem is that Latin letters in math are not slanted at all! I
only found that some tricky conversion is done by
original-youngryu-tx.map , but it's far beyond my understanding to fix
something in it.
Best regards,
Vyatcheslav
