PolygonArea


Module: FoundationBasic

Computes the area of polygon.

Name Type Description
Input value
inPolygon Path
Output value
outArea Real

Description

The operation computes the area of a polygon bounded by a closed path. The area is measured in square pixels. As paths in AVS are subpixel-precise, the result may be (and usually is) non-integer.

Note that if the input path is not a valid polygon (i.e. it has at least one self-intersection), the computation may lead to results that are not intuitive.

Examples

Area of the sample shape equals to 40652.37.

Area of the sample shape equals to 1287.675.
