dotlabel uses a pen to draw the dot, and I am not sure why it uses that rather than a path. Here is a (to me) simpler definition, where you can change the shape:
just look in the pdf ... in your case the dot is a n point path while otherwise it uses the default postscript pen (which is a dot)
Ah, that makes sense.
it surprised me that a math guru like you doesn't do this:
vardef dotlabel@#(expr s,z) text t_ = % draw textext("$\bullet$") scaled (1/2) shifted z ; % draw textext("$\blacktriangle$") scaled (1/4) shifted z ; draw textext("$\blacksquare$") scaled (1/4) shifted z ; label@#(s,z) t_ ; enddef ; \stopMPdefinitions
Ha! I know that you said this as a joke, but as someone who did try to use the old font-based picture environment in LaTeX back in the day, I would never try to use fonts for "drawing". Especially, math fonts, where every designer has a different idea of what the shape should look like. ah pictex memories ... drawing lines with cmr5 periods ...
but actually, we can define a stable font with symbols in metafun and use that (quite efficient too) and then one can even cut'n'paste those tiny symbols (don't worry ... not much of a challenge so low on my list) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
