Hi, I am not a specialist, but I use the « btex etex » commands, such as dotlabel.bot (btex \switchtobodyfont[10pt] \strut $R$ etex, z1) I just tested with the latest beta, and everything works fine, but not the \pmatrix construct (I tried also with ${k}\choose{n}$, which works fine too. I put my test file in which some maths is used in a MetaPost graphic here: http://dl.dropbox.com/u/4316076/test-graphique.tex http://dl.dropbox.com/u/4316076/test-graphique.pdf Best regards: OK On 30 nov. 2011, at 20:59, Hans van der Meer wrote:
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.
