CPolygon:Area

The Area method calculates the area enclosed by the CPolygon. The polygon does not need to be convex.

nArea = CPolygon:Area()

where

nArea is the area enclosed by the polygon.

The following script creates a CPolygon from 2 data arrays, x, and y, and then calculates its area:

A = NewPolygon( {4,5,6,7}, {1,2,-3,5} )	-- create CPolygon A
Printf("Area = %lg", A:Area() )	-- result: Area = 2
