tex, Latin Modern fonts - won't scale?

by **ricky** » Wed, 31 Oct 2007 01:19:55 GMT

I am having two (unrelated?) problems with the latin modern fonts.

1. The integral and summation signs will not scale. For example, the
\LARGE command seems to have no effect.

2. tex4ht does not properly render math text. For example, $f(x)$
displays as f(x) instead of something like <em>f(x)</em>.

I'm running the latest updated version of MiKTeX version 2.6 and
tex4ht on a windows 2003 machine. The problem with tex4ht seems to be
more recent.

thanks

\usepackage{exscale}

Not using it, sorry.

My example text:
\documentclass{minimal}
\begin{document}
\LARGE LARGE
\end{document}

! Undefined control sequence.
l.3 \LARGE
LARGE

No wonder it has no effect.

Oops. Quelle gaffe.

Though there might be some other solution, I simply use the default
fonts when compiling to html. This solves the <em>f(x)</em> problem.

See
http://groups.google.com/group/comp.text.tex/browse_thread/thread/4d3f31524f16771d/bbe882c1bfcdf595 #bbe882c1bfcdf595
for including portions of the document conditionally (in this case, the
lmodern package).

The computer modern fonts scale just fine (without the exscale
package). It's the latin modern fonts that exhibit the problem with or
without the exscale package. I've found a workaround but I like the
latin modern fonts so I hoped that some package would scale these as
well?

(really?)

you change to cm fonts for maths?

looking at the macros i don't see _why_ this is happening. if i
didn't know the guys who created latin modern, i would suspect
something wrong with metrics ... but that doesn't seem likely.

furthermore, i'm surprised you find exscale doesn't solve the
problem. loaded after lmodern.sty, it switches the extended maths
symbols back to cm, and that works for me.

(i assume your work-around involved switching back to cm for maths.
it would be nice to know, for sure, but of course, that's what exscale
is doing.)

I need the larger fonts for my calculus lectures (I use overheads).
The work-around was to use the pxfonts in these cases.

Now that I've loaded the exscale package after the lmodern fonts, the
scaling works as advertised. Thanks.

I was under the impression that the Latin Modern fonts were true
Postscript fonts in the sense that scaling of these fonts was not (in
general) a problem. I do understand that there are installation issues
to consider but I'm not sure where to look.

This is the contents of the file omxlmex.fd

\ProvidesFile{omxlmex.fd}[2007/01/14 v1.3 Font defs for Latin Modern]

\DeclareFontFamily{OMX}{lmex}{}
\DeclareFontShape{OMX}{lmex}{m}{n}{%
<->sfixed*lmex10%
}{}
\endinput

No wonder that it does not scale. Moreover, the font lmex is available
only at 10 pt and is identical to cmex10. I'd say that the only
solution (although not perfect at big sizes) is to use exscale and the
scalable CM fonts.

good. at least i've helped you past one hurdle ;-)

the cm fonts, in their usual type 1 format, are every bit as scaleable
as are the lm fonts. the problem is the macros to make the system
realise that these fonts should be allowed to scale.

i spent a little time playing with the lm issue, yesterday, but
couldn't work it out. it needs someone who knows the latex code
better, to examine what the lm people have done wrong ... or for me to
have some time (with a clear head at my disposal -- not currently
available) to start from first principles.

The following test document gives me the same results with or without
lmodern:

\documentclass{article}
%\usepackage{lmodern}
\begin{document}
Test {\LARGE $\int_0^1 f(x) \,dx$}
{\LARGE
\begin{equation}
\int_0^1 f(x) \,dx = g(1) - g(0)
\end{equation} }
\end{document}

Amazingly, no one seems to have asked you for
a minimal document.

And here is the contents of omxcmex.fd
which doesn't scale either:

\DeclareFontFamily{OMX}{cmex}{}
\DeclareFontShape{OMX}{cmex}{m}{n}{%
<->sfixed*cmex10%
}{}
\endinput

The real problem seems to be that if lmodern is loaded after
exscale, some of the font settings are put back the way they
were. Since the OP claimed cm scaled correctly, I assume
he originally used exscale but failed to tell us that.

He also failed to supply a minimal complete nonworking
document

That's why I said "no wonder". It's well known that the CMEX font
doesn't scale, unless exscale or amsfonts is loaded.

My first answer was to load exscale; it was obvious, in my mind,
that it had to be declared /after/ lmodern, since we want to
override its features.
