Syntax

public bool LengthParameter(
	double segmentLength,
	out double t,
	double fractionalTolerance
)

Public Function LengthParameter ( 
	segmentLength As Double,
	<OutAttribute> ByRef t As Double,
	fractionalTolerance As Double
) As Boolean

segmentLength: Type: System.Double
Length of segment to measure. Must be less than or equal to the length of the curve.
t: Type: System.Double
Parameter such that the length of the curve from the curve start point to t equals s.
fractionalTolerance: Type: System.Double
Desired fractional precision. fabs(("exact" length from start to t) - arc_length)/arc_length <= fractionalTolerance.

Type: Boolean
true on success, false on failure.
