struct PK_FACE_change_blend_o_s
{
int o_t_version; --- version number of option structure
double radius; --- radius of blend when reapplied (0.0)
};
typedef struct PK_FACE_change_blend_o_s PK_FACE_change_blend_o_t;
This structure contains blend-specific optional controls for PK_FACE_change.
Description of fields:
radius The value in radius defines the blend radius to be used when
reapplying the blend and must take a value greater than or equal
to zero. If radius is set to 0.0 (the default), the radius of
the blend when reapplied will be the same as that of the original
blend.
