TeX4ht converts all \(...\), \[...\], $$...$$ and other math environments to png format. However, it does not convert $...$ to png. It first tries to use html codes for $...$ math, and if it is not possible, then it converts to png.
Can I enforce TeX4ht to convert ALL math to png?
According to Advanced Usage of TeX4ht:
You can convert all inline math to picture format by putting the following commands in a configuration file:
\Configure{$}{\PicMath}{\EndPicMath}{}
\Configure{PicMath}{}{}{}{class=’’math’’; align=’’absmiddle’’}Note that, unless you want to make extensive use of TeX fields, there’s no way to do this selectively, so you may find yourself faced with a large increase in the number of images the program generates.
