Re: Auto selecting optical sizes for a font

["Keith J. Schultz" <keithjschultz@web.de>]

HI Georg, All,

as such ConTexT should support the use of the size table in its font handling,
but as Hans has mentioned design sizes a very special and few actually know 
what that information means and put it to a useful purpose.

Question would be in far this font feature should be rudimentarily supported.

regards
	Keith.

Fonts that come with different optical sizes do in fact use that table exactly for the purpose desired by Andrés. Latin Modern does so, Adobe fonts do so and EB Garamond happens to use that table too. XeLaTeX and LuaLaTeX interpret it correctly (by means of fontspec, IIRC). So perhaps it’s worth reconsidering this.
