dist2d_pt_seg() static double dist2d_pt_seg ( POINT2D *  p, POINT2D *  A, POINT2D *  B  ) static Return the 2D distance between the point the segment. Parameters [in] p Point [in] A,B Points defining the segment See also http://geomalgorithms.com/a02-_lines.html Note Derived from the PostGIS function lw_dist2d_pt_seg in file measures.c
