NAME
       FcWeightFromOpenTypeDouble - Convert from OpenType weight values to
       fontconfig ones

SYNOPSIS
       #include <fontconfig/fontconfig.h>

       double FcWeightFromOpenTypeDouble (doubleot_weight);

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