FcWeightFromOpenTypeDouble(3)			 FcWeightFromOpenTypeDouble(3)

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  be-
       tween  various  FC_WEIGHT_* constants. As such, the returned value does
       not necessarily match any of the	predefined constants.

SINCE
       version 2.12.92
