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

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 Fabrice.
