PolygonArea
| Header: | AVL.h |
|---|---|
| Namespace: | avl |
| Module: | FoundationBasic |
Computes the area of polygon.
Syntax
C++
C#
void avl::PolygonArea ( const avl::Path& inPolygon, float& outArea )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inPolygon | const Path& | ||
 |
outArea | float& |
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. |
Errors
