#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 sim-
ilar to CSS font-weight numbers. If input is negative, zero, or greater

ious FC_WEIGHT_* constants. As such, the returned value does not neces-
sarily match any of the predefined constants.
