Re: [NTG-context] Changing font and font size inside textex
Thanks Max that works perfectly! But It would still be useful if I could change families inside a MPpage. Sure, but you'll need to store the x-heights first: \starttexdefinition storexheight [#1] % Placing the first use of \switchtobodyfont inside a group messes % with the definitions, so we need to reset the font family manually. \edef\oldfontclass{\fontclass} \switchtobodyfont[#1] \expandafter\newcount\csname #1_xheight\endcsname \global\csname #1_xheight\endcsname=\numexpr 100 * \number\dimexpr1em\relax / \number\dimexpr1ex\relax \relax \switchtobodyfont[\oldfontclass] \stoptexdefinition \starttexdefinition setxheight [#1][#2] % Combining these two lines into one sometimes fails. No idea why. \switchtobodyfont[#1] \switchtobodyfont[\the\dimexpr#2 * \csname #1_xheight\endcsname / 100 \relax] \stoptexdefinition \storexheight[adventor] \storexheight[pagella] \storexheight[heros] \starttext \startMPpage draw textext.origin("\setxheight[adventor][1cm]Hello!"); draw (0, 1cm) -- (6cm, 1cm); \stopMPpage \startMPpage draw textext.origin("\setxheight[pagella][1cm]Hello!"); draw (0, 1cm) -- (6cm, 1cm); \stopMPpage \startMPpage draw textext.origin("\setxheight[heros][6pt]Hello!"); draw textext.origin("\setxheight[heros][24pt]Hello!"); draw (0, 6pt) -- (6cm, 6pt); draw (0, 24pt) -- (6cm, 24pt); \stopMPpage \stoptext It's pretty ugly code, but it seems to work alright. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] Changing font and font size inside textex
I'm using the following macro to set the font size via h-height: \starttexdefinition setxheight [#1][#2] \switchtobodyfont[#1, 12pt] \scratchdimen=\dimexpr#2\relax \switchtobodyfont[#1, \cldcontext{tex.dimen.scratchdimen / tex.sp"1ex" * tex.sp"1em" .. "sp"}] \stoptexdefinition But I can't figure out how to use that in MPpage. So it looks like the "\cldcontext" command doesn't work quite right inside "textext", and it also looks like "\switchtobodyfont" doesn't take effect until text is actually typeset when we're inside "textext". This seems to work: \starttexdefinition setxheight [#1] \switchtobodyfont[\the\dimexpr #1 * \number\dimexpr1em\relax / \number\dimexpr1ex\relax \relax] \stoptexdefinition \starttext \switchtobodyfont[adventor] \startMPpage draw textext.origin("\setxheight[1cm]Hello!"); draw (0, 1cm) -- (6cm, 1cm); \stopMPpage \switchtobodyfont[pagella] \startMPpage draw textext.origin("\setxheight[1cm]Hello!"); draw (0, 1cm) -- (6cm, 1cm); \stopMPpage \switchtobodyfont[heros] \startMPpage draw textext.origin("\setxheight[6pt]Hello!"); draw textext.origin("\setxheight[24pt]Hello!"); draw (0, 6pt) -- (6cm, 6pt); draw (0, 24pt) -- (6cm, 24pt); \stopMPpage \stoptext The catch here is that you need to set the font family *before* you start the MPpage. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
[NTG-context] Changing font and font size inside textex
Dear list, I want to be able to change the font and the font size inside a MPpage. But if I try to prepend \switchtobodyfont to the text inside textext it doesn't work. I'm using the following macro to set the font size via h-height: \starttexdefinition setxheight [#1][#2] \switchtobodyfont[#1, 12pt] \scratchdimen=\dimexpr#2\relax \switchtobodyfont[#1, \cldcontext{tex.dimen.scratchdimen / tex.sp"1ex" * tex.sp"1em" .. "sp"}] \stoptexdefinition But I can't figure out how to use that in MPpage. Any help would be appreciated.
