Have a look at how it's done in Wine (www.winehq.org) load_VDMX is used if the font has a VDMX table: http://source.winehq.org/source/dlls/gdi32/freetype.c#L4212 otherwise the fallback calc_ppem_for_height: http://source.winehq.org/source/dlls/gdi32/freetype.c#L3919 Elsewhere in that file you'll find how the rest of the metrics are calculated.
