Hello there,
I am new in variables in ConTeXt, so I tried the the following example
of two font-sizes wich should have a ratio of 0.7:
\setvariables[fontsize][bigsize=17pt]
\setvariables[fontsize][smallsize=0.7\getvariable{fontsize}{size}]
\definefont[big][name:arial at \getvariable{fontsize}{bigsize}]
\definefont[small][name:arial at \getvariable{fontsize}{smallsize}]
\starttext
\big Dies ist ein großer Text.\blank
\small Dies ist ein kleiner Text.
\stoptext
That does not work, what is the correct syntax?
should be: what is my error? ...
\setvariables[fontsize][smallsize=0.7\getvariable{fontsize}{bigsize}]
(size - bigsize)
but then the next hurdle is that you get 0.717pt so you need
\setvariables[fontsize][smallsize=\the\dimexpr0.7\dimexpr\getvariable{fontsize}{bigsize}\relax\relax]
which is why the next is better:
\definemeasure[fontsize:big] [17pt]
\definemeasure[fontsize:small][0.7\measured{fontsize:big}]
\definefont[big] [name:arial at \measure{fontsize:big}]
\definefont[small][name:arial at \measure{fontsize:small}]
\starttext
\big Dies ist ein großer Text. \blank
\small Dies ist ein kleiner Text.
\stoptext
Best wikify this!
Alternatively you can set up symbolic sizes (like we already have a b c
d), so that
\definefont[big] [name:arial sa a]
etc can be used
