Export baseline value for an equation from Latex

I requested to use the latex equation into InDesing application as an Image (exp: eps or jpeg or PDF, etc.). Is there any options for exporting the baseline value from the latex file for the inline equation.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation*}
F(x) &= \int^a_b \frac{1}{3}x^3
\end{equation*}
\end{document}
