MetaPost label font size

MetaPost label font size

[Henning Hraban Ramm via ntg-context]

How can I change the font size of labels within one picture?

Hraban

\startMPpage
defaultfont := "\truefontname{Sans}";
defaultfontsize := \the\bodyfontsize;

label.top(defaultfontsize, (0,0));

defaultfontsize := 4bp;

label.top(defaultfontsize, (50,0));
% shows that the variable changed,
% but font size is the same

\stopMPpage

(Untested): See https://www.contextgarden.net/Command/setupMPinstance

\setupMPinstance[metafun][textstyle=sans]

Or define a new instance, which sets the textstyle to sans.

Thank you for trying, but that doesn’t seem to have anything to do with 
my question.

I need a different font size for different labels within one picture.

My stupid way to get labels of different sizes:

\starttext

\startMPcode

  label("normal label", (0, 0));

  label("\setsmallbodyfont small label", (0, 18));

  label("\setbigbodyfont big label", (0, -18));

\stopMPcode

\stoptext

Okay. So there’s really no possibility to adapt whatever defines the 
label font size except defaultfontsize inbetween? Strange.

My solution so far was to split the picture and re-combine it afterwards.

I've used something like the following before.


\starttext

\startMPcode

  label("normal label", (0, 0));

  label("{\switchtobodyfont[3pt] tiny label}", (0, 18));

  label("{\switchtobodyfont[72pt] giant label}", (0, -72));

\stopMPcode

\stoptext

well, if there would be another way you would find it strange there if 
that would interfere with whatever else goes into a label text because 
we support arbitrary tex ... no way to figure out what struts, line 
distances, spacing, either of not adapt to current situation, delayed vs 
immediate inclusion, etc ... you can't have both worlds

if course you can make some macro (or define a highlight) and use that 
in the labels

Here are slightly different syntax that could be useful perhaps ? In the second one, the scaled parameter can be replaced easily with a variable, so you can decide and change the size of the label during the course of a picture.

\starttext

\startMPpage
defaultfont := "\truefontname{Sans}";
defaultfontsize := \the\bodyfontsize;

defaultscale := 0.5;
label.top("small label", (-10,0));

defaultscale := 1.0;
label.top("normal label", (50,5));
label.top("another normal label", (50,-5));

defaultscale := 2.0;
label.top("Huge label", (10,-25));

\stopMPpage

\startMPpage

 draw textext.top("small label") scaled 0.5 
 	shifted (-10,0) ;
 draw textext.top("normal label") scaled 1 
 	shifted (50,5) ;
 draw textext.top("second normal label") scaled 1 
 	shifted (50,-5) ;
 draw textext.top("Huge label") scaled 2 
 	shifted (10,-25) ;
 	
\stopMPpage

\stoptext

Thank you (all), I resolved to using the usual \tfx or \definedfont.
