Is it possible without creating a new font to define a new math symbol (e.g. with \newcommand) and then use it with such commands as \limits, _ and ^ (up and down limits)?

For example, I define it like this:

\newcommand{\bigrint}{\scalebox{1.2}[1] {\rotatebox[origin=c]{15}{$\displaystyle\int$}}}
\newcommand{\rint}[2]{ \substack{\hspace{-4pt} #2 \\ \hspace{-5pt} \bigrint \hspace{-3pt}\\ #1}\hspace{-1pt} }

And I want to use it like \rint_1^2.

  \hbox to .2em{\hss\scalebox{1.2}[1] {\rotatebox[origin=c]{15}{$\displaystyle\int$}}\hss}}

Here is an alternative way which works I believe the same as you want:


    \int\limits_a^b\! x\di x = \tfrac{1}{2}x^2\Big|_a^b
