What you actually need is a cff2afm program, however, this doesn't exist... BUT: You can use FontForge to load any font, then converting it to a Type1 font and an AFM file. I just tried it for `Linux Biolinum' (from the Libertine family): The AFM file has a whopping size of 2.6MByte, with 2479 glyph metrics and 109131 kernpairs... BTW, this should work on any platform since FontForge can be controlled by two scripting languages (either a native one or with a Python interface) which doesn't use a GUI. Werner
