I would like to put some math in metapost pictures. For the moment I am using textext for the typesetting in my metapost macro: pic := textext("\setbox0=\hbox{\color["&textcolor&"]"&labeltext&"}\dp0=0pt\box0"); picture pic will be placed in the metapost figure.
Simple math like $p=2$ works fine, but the system chokes on something like the following matrix: $\pmatrix{p_{0|0}\cr}$ (it does fine in ConTeXt itself).
The error is: ! Only one # is allowed per tab. system> tex> error on line 6 in file Info/kanaalmatrix.tex: Only one # is allowed per tab ...
Perhaps I am too optimistic about textext's possibilities. But how can I accomplish the placement of these and more elaborate formulae in metapost pictures using ConTeXt? It is of the essence for a series of Powerpoint slides I am preparing, wheein these formulae must be placed as individual pictures.
you can patch pmatrix: \unexpanded\def\pmatrix#1% {\left(\matrix{#1}\right)} (i'll make the lot unexpandable) btw, for large chunks you can consider using setups \startsetups lots-of-math \stopsetups ... \textext("\setup[lots-of-math]") ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
