Text replacement - "</cmd>" to "}}"
Currently, I normalise all fonts to match with Computer Modern Roman's x-height, which is 5.16667 points for a font size of 12 pt. Seeing that that was a little small, I implemented a variation for larger-eyed fonts, where all fonts are normalised around an x-height of 6.0 pt for the same body font size. Following me yet? How about this:
: When you use {{cmd|setupbodyfont[flex]</cmd>}}, you get the typescripts you called previously, accessible as <tt>rm</tt>, <tt>ss</tt>, etc. (as appropriate), all relatively scaled so that their x-height matches up with that of CMR.
Okay then, how about an example. Given the following in a typescript that gets loaded:
</texcode>
...and you get Palatino (serif and math) with Helvetica, both scaled to a compatible x-height. That seems more complex than necessary, given a one-time use, but the power behind FlexiFace lies in the endless combinations, and that it's embedded in the natural {{cmd|usetypescript</cmd> }} calls. Once it's set up, you only need to worry about calling one typeface/bodyfont.
Some side-effects to watch out for:
* The typeface doesn't make <tt>rm</tt> the default, so watch out. It's best to put 'rm' (or your choice) into the {{cmd|setupbodyfont</cmd> }} call, as above. (Hans points out that {{cmd|setuptypeface[flex][default=rm]</cmd> }} is just as effective, and it's probably better in a local config file.)
* An x-height to match CMR is a bit small for most fonts&mdash;and it can distort the actual size of the font&mdash;so either be aware of this global rescaling (e.g., the &ldquo;12pt&rdquo; Palatino above actually comes out at 10.92pt after scaling) or use the <tt>flex2</tt> alternative.
* This system depends on a &ldquo;correct&rdquo; ConTeXt font installation&mdash;it doesn't manage any magic if you haven't run TeXfont or use the berry typescripts.
