well, using html5&canvas , in createxo something like
this could be produced
(of course things in createxo are more complex than directly written in ‘wims phtml’)
\text{fun=wims(mathmlmath \frac{1}{x^{2}})}
\text{math_x = wims(mathmlmath x)}
\text{plus_infty = wims(mathmlmath +\infty)}
\text{min_infty = wims(mathmlmath -\infty)}
\text{f = wims(replace internal " by ' in \fun)}
\text{x = wims(replace internal " by ' in \math_x)}
\text{infp = wims(replace internal " by ' in \plus_infty)}
\text{infm = wims(replace internal " by ' in \min_infty)}
\text{src=size 400,200

}
\text{img=wims(exec canvasdraw \src )}
\statement{
img = \img
<input type="button" value="click" onclick='javascript:var fun=eval("read_canvas"+canvas_scripts[0]);alert(fun());' />
}instead of calling wims_mathml and replace stuff… (needed for createxo), you could use unicode
string color,x,y,\unicode
kind regards,
joke
