ParallelLine(System.Double distance, System.Double minSegmentLength, LineJoin lineJoin)
Returns a LineGeometry that is parallel to this LineGeometry.Syntax
public LineGeometry ParallelLine (
System.Double distance,
System.Double minSegmentLength,
LineJoin lineJoin
)Parameters
distance
Type: System.Double
The distance of the new line from the current line. A positive value will return a parallel line the is offset to the left of the current line and a negative value will return a line offset to the right of the current line. Unit: same as the coordinates of the line geometry.
The distance of the new line from the current line. A positive value will return a parallel line the is offset to the left of the current line and a negative value will return a line offset to the right of the current line. Unit: same as the coordinates of the line geometry.
minSegmentLength
Type: System.Double
Segments shorter than this value will be removed to speed up calculations. Zero will use all segments to calculate the result. Unit: same as the coordinates of the line geometry.

lineJoin
Type: LineJoin
Determines how the new parallel line segments will be joined together.
Determines how the new parallel line segments will be joined together.
Return Value
Type: LineGeometry
A line that is parallel to the current line or a null reference if a parallel line could not be generated.
A line that is parallel to the current line or a null reference if a parallel line could not be generated.
Remarks
This method can fail and return a null reference in some cases, for example when the line is a small closed loop.
Note
This method operates on 2D geometries and all z-coordinate values are ignored.
