Render Math/Latex in Kivy

[Paul Royik]

Is it possible to render latex/mathjax or something else in kivy, so that math formulas are rendered correctly?

I tried RstDocument with a^2+b^2=c^2 but it doesn't work.

I haven't seen anyone do this. One option might be to find a way to render the formulae to png and display them inline. This must be possible as emacs has a mode that does it, and it's probably the basis for some of the latex -> html converters.

Here is an open source tex2png converter written in c++: http://www.nawouak.net/?cat=informatics.tex2png+lang=en

I imagine you could wrap this with cython to create a "TeX Labels" class. Sounds like a project for kivy.garden.

Oooh, better yet, here's one for python: https://pypi.python.org/pypi/tex2pix

What about this post?

I tried it but got following errors:

import error to android.runnable

and can't find android.webkit.WebView

Have you considered just using a specialized maths font and specifying the characters? e.g. Asana maths has a huge amount of maths symbols...

I think the issue is that you might want to type out a math document similar to how you would write an html file and you want kivy to render that document correctly.

I'll eventually need math type in my app in this manner and I'm looking into using mathjax to produce SVG that can then be displayed in Kivy, however, I'm waiting for SVG to stabilize in Kivy before I get too far in my attempt.

Well, it really depends on your need. Arash GM stated he "just" need a subscript, in which case a font is perfectly acceptable. It would be ideal to have a full maths render, but that is far from simple. Often we just need a solution for the immediate problem, not ideal solutions. I was just replying to that...:-)
