MathTime Professional 2 fonts on only a single line?

Question

How could one use MathTime Professional 2 fonts on only one line of text (in math mode) in a document, where every other line of text (in math mode) displays as though the mtpro2 package is not being used at all?

Answer 1

Here's a somewhat kludgy suggestion:

Create a one-line document using the standalone document class. Suppose this text file is called mmm.tex:

%% mmm.tex 
\documentclass[border=0.25pt]{standalone}
\usepackage{mtpro2}
\begin{document}
$\displaystyle a^2+b^2=c^2$
\end{document}

Compile this tex file; let's assume the resulting pdf file is called mmm.pdf.

Next, set up a "regular" tex file:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\[ \raisebox{-0.25ex}{\includegraphics{mmm}} \]
\end{document}

The contents of mmm.pdf -- the one-line equation -- will show up as the contents of the display-math environment. Use the first argument of \raiesebox to raise (positive argument) or lower (negative argument) the graphic.
