my Latex and Tex4ht cheat sheet

Now the file foo2.html will display in the browser as
notice: The math does not show up in the HTML. This is a known issue with using math+tickz+htlatex see
http://tex.stackexchange.com/questions/124682/error-using-htlatex-with-tikz-forest-package-invalid-
A better approach is this: Use separate latex file to make the diagram using tikz. Use standalone class. Then
generate the pdf file using pdflatex.
Next convert the pdf to png, then using a separate latex file, include this image as png where it needs to go.
This way htlatex and pdflatex will be able to process it ok. Here are the steps.
1. make separate latex file for each diagram. For example diagram.tex
\documentclass{standalone}
\usepackage{tikz
}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}
\node {root}
child {node {$\frac{a}{b}$}};
\end{tikzpicture}
\end{document}
2. compile the above file to pdf
pdflatex diagram.tex
3. convert the pdf file to png
pdftoppm -png diagram.pdf > diagram.png
or
convert -density 200 -limit memory 64MB -limit map 128MB -colorspace RGB diagram.pdf diagram.png
\begin{X311}
%
\item create the latex file which will use the above diagram, say \verb|main.tex|
\begin{X311}
\documentclass{article}
\usepackage{graphicx}
\begin{document}
The following diagram was generated using tikz+latex in
a separate file
\includegraphics{diagram.png}
and it is now in html
\end{document}
