Returns a copy of this curve as a line. All arcs are approximated with the number of points given by ‘numSamples’. If ‘numSamples’ is 0, the number points will first be determined by the value of
kFMEStrokeMaxDeviationValuedirective in mapping file, which denotes the maximum deviation of the arc from the line. In the absence of this directive or the value of this directive is smaller than or equal to 0, the number points will be determined by the arc’s sweep angle and the value of the mapping file directive
kFMEDegreesPerEdge, which defaults to 5.
