How MathJax works?

[wangzhi...@gmail.com]

Hello alI,

I am new to MathJax. I am trying to develop a stand alone local MathJax rendering component for Qt. With Phantomjs and QScriptEngine, I could get the screen shot of the html page. However, there is a problem, the MathJax rendering is not there. I tried to open the HTML page with chrome browser, and MathJax works fine. To eliminate the possibility of Phatmomjs failing to execute in page javascript, I added a small testing javascript. The result is, in page testing javascript was executed, but the MathJax javascript failed as before. The attached png is the screenshot result from phantomjs. Does anyone have a clue?

Since MathJax runs after the page is loaded, you need to make sure you give it time to do its work.  I suspect you are taking the snapshot too soon, and so MathJax hasn't run yet.  You need to synchronize your snapshot with MathJax.

See the code sample at

https://groups.google.com/d/msg/mathjax-users/nQXVaFi4IKQ/AwZ-UrRhiDAJ

as this does handle the synchronization with phantom.js.  Perhaps you can use a similar approach in your situation.  Otherwise, you may need to give the actual code you are working with, since we really have nothing to go on here.
