SqlGeometry.CurveToLineWithTolerance Method (Double, Boolean)
Returns a polygonal approximation of a SqlGeometry instance that contains circular arc segments.
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
The maximum error between the original circular arc segment and its linear approximation.
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.
