FIL.RegionElongation

Computes the elongation factor of a region ( perfect circle has minimal elongation equal 1.0 ).

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void RegionElongation
(
	FilNet.Region inRegion,
	out float outElongation
)

Parameters

Name Type Range Default Description
inRegionFilNet.RegionInput region.
outElongationfloat

Description

Elongation is a measure of how long the shape is in relation to its width. The perfect circle has the minimal elongation equal to 1.0, while the upper bound doesn't exist. The operation internally approximates the region with an ellipse, and then computes the result as: Where L denotes the longer axis of the approximating ellipse, and S denotes the shorter one.

Examples

Elongation of the sample region equals to 1.702.

Elongation of the sample region equals to 3.168.
