RegionsOperatorsmRgnHoleAreaRatio Method

Ratio of region area excluding holes to total area of region.

Namespace:  MediaCy.IQL.Operators
Assembly:  MediaCy.IQL.Operators (in MediaCy.IQL.Operators.dll) Version: 3.1.0.0
Syntax
VB
Copy
<ExtensionAttribute>
Public Shared Function mRgnHoleAreaRatio ( 
	regions As McRegions
) As McMeasure

Parameters

regions
Type: MediaCy.IQL.FeaturesMcRegions

Return Value

Type: McMeasure

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type McRegions. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
This is a pixel-based measurement. It will be less than 1 only for regions created by the McThreshold.Execute method or McFeatures.SetFromMask method (features of Type mcftScanList).
