Change font size

Question

I trying to change the size of the eurm font in a paper by defining it like this:

\font\twelveeurm=eurm12 \font\eleveneurm=eurm11 \font\teneurm=eurm10 \font\nineeurm=eurm9 
\font\eighteurm=eurm8 \font\seveneurm=eurm7 \font\fiveeurm=eurm5 \newfam\eurmfam
\textfont\eurmfam=\teneurm \scriptfont\eurmfam=\nineeurm \scriptscriptfont\eurmfam=\fiveeurm
\def\eurm#1{{\fam\eurmfam\relax#1}}

I am using the packages euler, amsmath, amsthm, amssymb, showlabels in the preamble. One character has been defined:

\def\g{\text{{\twelveeurm g}}}

I keep getting these error messages:

\twelveeurm=eurm12 not loadable: Bad metric (TFM) file.

I wasn't able to read the size data for this font, so I will ignore the font specification; and a similar message with \eleveneurm. My apologies for the log post

Answer 1

you're overriding the built-in font control for euler. euler, all by itself, changes size along with its surroundings, so specifying the size in ordinary latex terms should suffice.

this definition should produce what you want:

\def\g{\text{\Large $g$}}

(this assumes that \Large is equivalent to 12pt in the document class you are using.)

edit: here is an example. the "open g" shape, while characteristic of many italic fonts, is the shape chosen for euler to emulate handwriting.

\documentclass{article}
\usepackage{amsmath}
\usepackage{euler}
\def\g{\text{\Large $g$}}
\begin{document}
Here we want a large Euler ``g'': $\g$.

\medskip
Some more math: $a + b = c$.

In the absence of other adjustments, the \texttt{euler}
package changes all math letters to upright cursive.
