AVL.PolygonArea

Computes the area of polygon.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void PolygonArea
(
	AvlNet.Path inPolygon,
	out float outArea
)

Parameters

Name Type Range Default Description
inPolygonAvlNet.Path
outAreafloat

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.
