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 doubleerpolates between  various
       FC_WEIGHT_*  constants.  As such, the returned value does not necessarily match any of the
       predefined constants.
