All,
I was trying to help a student today and the following came up.
drawarrow anglebetween(path1, path2, btex $\theta$ etex)
Is there some way to typeset the theta with an "unfilled" background?
I know there is a metapost way to do this, but cannot recall where I read that. Something along the lines of (untested) pic p; p := btex $\theta$ etex ; unfill (boundingbox p) at the right location ; draw p ; However, if you are using the ConTeXt interface, there are easier ways. This is what I sometimes use \definetextext[parbox] {\framed [ frame=off, width=2cm, height=.85cm, autowidth=no, %also try yes align={middle,middle}, backgroundcolor=white]} And then \startMPcode drawarrow anglebetween (path1, path2, \sometxt[parbox]{$\theta$} ; \stopMPcode Aditya
