Trying to findout how ConTeXt's font mechanism works, I come to following question: From the brochure "Fonts in Context" (mfonts.pdf) I have picked up the notion that exercising a call to \definetypeface gets fonts in working order (see the examples there on font specifiers "funny" and "whow", for example, and the resulting typeface collection). Also in file type-exa.tex there is a typescript [postscript] where \definetypeface is exercised, seemingly to bring a matched series of times, helvetica and courier into existence. However, the usage of the postscript fonts via \setupbodyfont[pos] seems to be completely unconnected with this script (I traced the typescript checking). Neither can I find somany calls to \definetypeface (and its derivatives \dodefinetypeface and \dododefinetypeface); it seems they are barely used in the code. So, the questions are: - Does \setupbodyfont[pos] results in the scaled font set as given in type-exa? - Or does \definetypeface belong to an alternative/obsolete font definition scheme, totally unrelated to the definitions called up in the scripts in type-pre.tex, type-syn.tex, and other friends? - In preparing font scripts, can I therefore totally ignore \definetypeface or will that be disastrous for the result? If somebody would be so kind to enlighten me... Hans van der Meer
