SqlGeography.CurveToLineWithTolerance Method

Returns a polygonal approximation of a SqlGeography instance that contains circular arc segments.

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

Syntax

'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function CurveToLineWithTolerance ( _
    tolerance As Double, _
    relative As Boolean _
) As SqlGeography
'Usage
Dim instance As SqlGeography
Dim tolerance As Double
Dim relative As Boolean
Dim returnValue As SqlGeography

returnValue = instance.CurveToLineWithTolerance(tolerance, _
    relative)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeography CurveToLineWithTolerance(
    double tolerance,
    bool relative
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeography^ CurveToLineWithTolerance(
    double tolerance, 
    bool relative
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member CurveToLineWithTolerance : 
        tolerance:float * 
        relative:bool -> SqlGeography

public function CurveToLineWithTolerance(
    tolerance : double, 
    relative : boolean
) : SqlGeography

Parameters

• tolerance
  Type: System.Double
  The maximum error between the original circular arc segment and its linear approximation.

• relative
  Type: System.Boolean
  Specifies whether to use a relative maximum for the deviation. If false (0), an absolute maximum is set for the deviation that a linear approximate can have. If true (1), tolerance is calculated as a product of the tolerance parameter and the diameter of the bounding box for the spatial object.

Return Value

Type: Microsoft.SqlServer.Types.SqlGeography
A polygonal approximation of a SqlGeography instance that contains circular arc segments.
