A convex polygonal region having n- vertices {P₀, P₁, P₂..., P_{n - 1}, P_n, P₀} or lattice points to be identified by the user includes the convex window area. To be exact about the window we may be that all edges between two points contributes to the boundary of that window i.e. under the situation when we traverse all edges in anticlockwise manner, the window region lies on left hand side or LHS of edge. Such orientation is preserved and whereas giving input, the user cares for the orientation to identify the window region or area of any arbitrary convex shape.
