typedef int PK_BCURVE_extension_t;

Used in:

PK_extend_control_t

This datatype specifies the method used to decide how far to extend a bcurve.

It has the values:
    PK_BCURVE_extension_none_c          No extension requested.
    PK_BCURVE_extension_distance_c      Extend by a given arc length distance.
    PK_BCURVE_extension_to_parm_c       Extend to a given absolute parameter
                                        value.
    PK_BCURVE_extension_parm_ratio_c    Extend parameter boundary by a ratio of
                                        the current parameter range. 'value' is
                                        the proportion of the current parameter
                                        range.
