# Are picture environments not allowed in MathJax?

In a WordPress blog post of mine I used the following LaTeX code:

$\setlength{\unitlength}{1cm} \begin{picture}(8,6)\thicklines \put(1,1){\line(3,4){3}} \put(4,5){\line(3,-4){3}} \put(1,1){\line(1,0){6}} \put(2.3,3.2){\textit{b}} \put(5.7,3.1){\textit{a}} \put(3.8,0.5){\textit{c}} \put(4,2.7){\textit{S}} \put(0.6,0.5){\textit{A}} \put(7.1,0.5){\textit{B}} \put(3.8,5.3){\textit{C}} \end{picture}$


to draw a triangle. I tried to do the same in this answer but it didn't parse.

Question: Is this feature not allowed/supported?

Added: From the Willie Wong's comment to J. M.'s answer it seems this is due to the existing design of the system. Is that so?

It's not in this list, so I guess not.

• MathJAX is for type setting mathematics. It only supports that subset of the LaTeX features. As an aside: WordPress doesn't use MathJAX. WordPress pipes the LaTeX code to a real processor (probably TeXLive), gets an image output, and pastes the image output into the post. Which adversely affects the print quality. – Willie Wong Aug 5 '11 at 16:13
• @Willie Wong: Thanks! Where can I get a short description of MathJAX? – Américo Tavares Aug 5 '11 at 16:43
• @Américo: is the official mathjax.org page good enough? – t.b. Aug 5 '11 at 18:58
• @Theo: Yes, it is. Thanks! – Américo Tavares Aug 5 '11 at 19:23
