DESCRIPTION

15       FcWeightFromOpenTypeDouble  returns  an  double  value  to   use   with
16       FC_WEIGHT,  from an double in the 1..1000 range, resembling the numbers
17       from OpenType specification's OS/2 usWeight  numbers,  which  are  also
18       similar  to  CSS  font-weight  numbers.  If input is negative, zero, or
19       greater than 1000, returns -1. This function linearly interpolates  be‐
20       tween  various  FC_WEIGHT_* constants. As such, the returned value does
21       not necessarily match any of the predefined constants.
