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.
