- Here we load extra AFM libraries from Context.
- In fact, part of the AFM support is contained in font-ext.lua, for
- which the font loader has a replacement: luatex-fonts-ext.lua.
- However, this is only a stripped down version with everything AFM
- removed. For example, it lacks definitions of several AFM features
- like italic correction, protrusion, expansion and so on. In order to
- achieve full-fledged AFM support we will either have to implement our
- own version of these or consult with Hans whether he would consider
- including the AFM code with the font loader.
+ As of 2013-08-25 AFM support has been included in the fontloader
+ package.
- For the time being we stick with two AFM-specific libraries:
- font-afm.lua and font-afk.lua. When combined, these already supply us
- with basic features like kerning and ligatures. The rest can be added
- in due time.
+ We still have to load the font feature definitions (font-afk.lua) to
+ achieve kerning and ligatures.
