<function>FcWeightFromOpenTypeDouble</function> 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.
