 int CalcSiDeterm(ref MapWinGIS.Shapefile lineSF, ref MapWinGIS.Shape polygon, ref int[] intersectsPerLineSeg, ref MapWinGIS.Point[][] intersectionPts, ref int[][] polyIntersectLocs)


Calculates the determinants for line segments with a polygon
to see if any intersections will occur. -- Angela Hillier 10/05


lineSF A line shapefile of 2pt segments.
polygon The polygon to test for intersections with.
intersectsPerLineSeg Out parameter: an array of numbers representing how many
intersections will occur for each line segment.
intersectionPts Out parameter: an array of points, if the point is != (0,0) then
it represents a valid intersection point at the corresponding location in the polygon.
polyIntersectLocs Out paramter: an array of indicies corresponding to where in the polygon
an intersection point is found.


The total number of intersections found for the line shapefile.
