Fast_ProcessPartInAndOut(ref System.Boolea insidePts, ref MapWinGIS.Shape line, ref MapWinGIS.Shape polygon, ref MapWinGIS.Shapefile resultSF)


Given a line that contains portion both inside and outside of the polygon, this function will split the polygon based only on the segments that completely bisect the polygon. It assumes: out->out, and in->in 2pt segments do not intersect the polygon, and out->in, in->out 2pt segments have only one point of intersection.


Name Description
insidePts A boolean array indicating if a point is inside the polygon or not.
line The line that intersects the polygon.
polygon The polygon that will be split by the intersecting line.
resultSF The shapefile that the polygon sections will be saved to.


False if errors were encountered or an assumption violated, true otherwise.
