Decide if it makes sense to close off this curve by moving the endpoint to the start based on start-end gap size and length of curve as approximated by chord defined by 6 points.

VB

Public Function IsClosable ( 
	tolerance As Double,
	minimumAbsoluteSize As Double,
	minimumRelativeSize As Double
) As Boolean

tolerance

Type: System.Double
Maximum allowable distance between start and end. If start - end gap is greater than tolerance, this function will return false.

minimumAbsoluteSize

Type: System.Double
If greater than 0.0 and none of the interior sampled points are at least minimumAbsoluteSize from start, this function will return false.

minimumRelativeSize

Type: System.Double
If greater than 1.0 and chord length is less than minimumRelativeSize*gap, this function will return false.

Type: Boolean
true if start and end points are close enough based on above conditions.
