[tex4ht] SVG figures cause font styling to be lost

[Nasser M. Abbasi]

I can't tell why it does not work when including the tex
source code for the tikz pic.

But here is a workaround. The result is in a zip with my .cfg included
which is at this link:

http://12000.org/tmp/053105/bobs_figures.zip

I changed your latex file to be to include the image itself
instead of include the tikz code. This means some pre-processing
is needed:

-------------------------------------------
\documentclass{article}
\usepackage{graphicx}
\begin{document}

Here \textbf{is} a \texttt{circuit} for \textit{you}.

\begin{figure}[!ht] \centering
\includegraphics[width=0.5\paperwidth]{book_figs/t_circuit}
\caption{Here \textbf{is} a \texttt{circuit} for \textit{you}.}
\end{figure}

Here \textbf{is} a \texttt{circuit} for \textit{you}.
\end{document}
-----------------

Then made the tikz file to be self contained document:

----------------------------------
\documentclass{standalone}
\ifdefined\HCode
\def\pgfsysdriver{pgfsys-tex4ht.def}
\fi
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[scale=2.54]
.....
\end{tikzpicture}
\end{document}
-----------------------------

Then compiled it

pdflatex t_circuit.tex

then convert to svg using

pdf2svg t_circuit.pdf t_circuit.svg

and now build the main tex file using:

make4ht -d html -c nma.cfg my_fig.tex

Now it work. The fonts changes correclty below the image.

The zip file has the .cfg and the generated HTML so you can see the result.

Again, I do not know why it does not work when including the tikz source
code directly.
