Returns

The computed value.

GetCircularity()

float oevislib_net.Path.GetCircularity ( CircularityMeasure inCircularityMeasure )

inline

Computes the path circularity, defined as the polygon area divided by the area of the circle having the same provided feature.

It returns a correct result only if the path is actually a polygon (close and without self-intersections).

Parameters

inCircularityMeasure

Equivalent circle feature.

Returns

The computed value.

GetConvexity()

float oevislib_net.Path.GetConvexity ( )

inline
