ShapeArea
Computes the area of a shape.
| Name | Type | Description | |

inShape | Path | |

outArea | Real |
Description
The operation computes the area of a shape bounded by a closed path. The area is measured in square pixels. As paths in FIS are subpixel-precise, the result may be (and usually is) non-integer.
Note that if the input path is not a valid shape (i.e. it has at least one self-intersection), the computation may lead to results that are not intuitive.
Examples
Description of usage of this filter can be found in examples and tutorial: Mounts (Contour Analysis).
Area of the sample shape equals to 40652.37. |
Area of the sample shape equals to 1287.675. |
