The main problem we want to be solved is the problem with the antialising of the polygons. When we are trying to use [login to view URL] for the polygons the border of the polygon is smooth but the problem is with the intersecting section of the polygons where the thin white line appears due to the antialias.
And in case of Antialias kept default the thin white line previously appeared on the intersection line between two polygon is gone. But the problem in this case is that the border of the Polygons are not smooth.
