outlinetext, fractions, and square roots
Hi, When experimenting with outlinetext, I found it generally works well for both text and equations but seems to fail for fractions or square roots. The code below demonstrates the issue: ____________________________ \startMPpage draw outlinetext("$\frac{1}{\sqrt{2}}$"); \stopMPpage ____________________________ The ‘1’ and ‘2’ seem to be at the right positions, but the fraction bar and horizontal part of the radical are missing. Is there a different fonction I should use for getting the outlines of equations? Best regards, Florent

In order to get rules you need this: \setupmathfractions[rule=yes] \setupmathradical [rule=yes] I suppose this is something we can hook in automatically so we need to discuss that in the cms. You can also do this: \disabledirectives [math.extensibles] In both cases there is a too large radical symbol so this fix is needed in mlib-fnt.lmt (line 399): local s = 1000 local sx = 1000 local sy = 1000 After that it should be ok. I need to check the directive but might as well just leave that as 'not worth the trouble' because going into an assembled glyph is no fun. \starttext \startMPpage draw lmt_outline [ text = "$\frac{1}{\sqrt{2}}$" ] ; \stopMPpage \startTEXpage $\frac{1}{\sqrt{2}}$ \stopTEXpage \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
Hi Hans,
Thanks a lot for that! I confirm that these methods, along with the change
in mlib-fnt.lmt you suggested, work perfectly.
Cheers,
Florent

\starttext
\startMPpage draw lmt_outline [ text = "$\frac{1}{\sqrt{2}}$" ] ; \stopMPpage
\startTEXpage $\frac{1}{\sqrt{2}}$ \stopTEXpage
\stoptext
