path.intersectionWithLine(line [, opt])

Return an array of the intersection points of the path and the line. Return null if no intersection exists.

The opt argument is optional. Two properties may be specified, opt.precision and opt.segmentSubdivisions, which determine maximum error allowed in pointAtLength calculations for curved segments (default precision is 3; this corresponds to maximum observed error of 0.1%). The opt.segmentSubdivisions property is an array of individual segments' subdivision arrays. The path.getSegmentSubdivisions() function may be used to obtain the segmentSubdivisions array. The opt.precision property is still necessary, however; it determines the precision of the point search algorithm in curved segments.
