Please just close this task if I misunderstand something :)
There are currently three options for Math rendering:
- PNG images
- LaTeX source (for text browsers)
- MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools)
"LaTeX source" is useful for people who use text browsers. The primary reason for that is accessibility for people who don't see the formulas. Are there people who are interested in seeing LaTeX source for any other reason? If not, can it be removed? Isn't the alt attribute enough for text browsers and accessibility tools?
Furthermore, if I understand its name correctly, the MathML option covers pretty much all use cases:
- Browsers that can render it, do it well.
- Browsers that cannot do it, fall back to PNG.
- Browsers that don't show images and users who don't want or cannot see images, see LaTeX source in alt text.
If that option indeed covers all use cases, are preferences needed at all? Perhaps they can be removed entirely? In general, having less preferences is a Good Thing, unless there is a particular reason to have them, and I don't see such a reason here, but I might be wrong.
The three options mentioned above are used on Wikimedia sites. In the source there's also something called "LaTeXML", but I don't remember ever seeing it in action, and I'm not sure where is it used or for what. In any case, if the three options above can be merged into one, then on sites where no other option can be used, there shouldn't be a Math section in the preferences.
If, for any reason, there is demand for a separate "LaTeX source" option, can the "PNG" option be removed? Is there anybody who consciously prefers PNG to SVG / MathML, despite using a browser that supports them?
(Tagging MediaWiki-User-preferences, even though this task is not in core, out of assumption that Math is a popular extension and that this may interest people who care about preferences in general. If it's inappropriate, please feel free to remove the tag.)
