Filter to create sideways figures

Filter to create sideways figures

I have several wide figures in a large document that need to be displayed 
landscape. Using the LaTeX package rotating, I can use 
\begin{sidewaysfigure} and get this result very easily. The current tex 
file generated from my markdown looks like this:

![Example figure](/location/of/image.png){#fig:blah}

\begin{figure}[htbp]
\centering
\includegraphics{/location/of/image.png}
\caption{Example figure\label{fig:blah}}
\end{figure}

Is there a way for a filter to replace \begin{figure}[htbp] and 
\end{figure} with \begin{sidewaysfigure} and \end{sidewaysfigure} if there 
is a tag like so: ![Example figure](/location/of/image.png){#fig:blah 
sidewaysfigure}? Any advice would be helpful. I have been trying with no 
success.

Personally, whenever I need to do something like this I just generate
the LaTeX source and I post-process it using a suitable script and
then invoke `latexmk` on it.

That's the easiest approach.  Another possibility would be
to temporarily redefine the figure environmentn before your
figure.  With a filter, you'd have to generate all of the
LaTeX code for the figure; there's no way to change just the
environment name.
