A few thoughts #1

Closed TrueV closed 8 years ago

TrueV commented 8 years ago

Hey there, first of all, thank you for the great work putting this together as it will come in pretty handy for me further on, because I have no idea how to get MathJax working in my App.

Well, I noticed a few things, where you can perhaps help me with:

  1. I made an MathView Element in my XML file and tested the performance of the rendering, which was noticeable slow. Is this a problem occurring also with MathJax as a standalone version? - If not, is there a way to speed up the render process?
  2. Do you have a documentation about the usable functions and how to implement them? (Can I just use this for reference?: http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference )
  3. Could you give an example for using MathJax in Java to render variables coming from, for example, Strings?

Greetings

Hi TrueV, thank you for your feedback. About the questions you posted.

  1. I suppose the bottleneck is MathJax itself. In order to shrink the size of MathJax, I limited the output to be HTML rather than SVG, usually the latter is ~25% faster. This document gives an overview of the different aspects that affect MathJax performance as well as several potential development options to improve performance.
  2. I haven't done a thorough test, but I think it's OK to use it for reference except that, to insert inline formua, you should use \(...\) rather than the dollar sign notation.
  3. I've update the readme document, please have a look on it.

Anyway, this lib is still rather primitive. Thank you for your attention. Pull Requsts are always welcome. :)
