BufferZone(System.Double distance, System.Int32 arcAccuracy)
Returns a buffer zone for the LineGeometry.Syntax
public PolygonGeometry BufferZone (
System.Double distance,
System.Int32 arcAccuracy
)Parameters
distance
Type: System.Double
The distance between the line and the buffer zone boundary. Must be positive. Unit: same as the coordinates of the line geometry.
The distance between the line and the buffer zone boundary. Must be positive. Unit: same as the coordinates of the line geometry.
arcAccuracy
Type: System.Int32
Specifies the arc accuracy, as the number of straight line segments that would be used for a full 360 degree arc. The number must be at least 2.
Specifies the arc accuracy, as the number of straight line segments that would be used for a full 360 degree arc. The number must be at least 2.
Return Value
Type: PolygonGeometry
The buffer zone around the line or a null reference if the buffer zone could not be generated with the specified values.
The buffer zone around the line or a null reference if the buffer zone could not be generated with the specified values.
Remarks
Note
This method operates on 2D geometries and all z-coordinate values are ignored.
