Description

Converts lines to polygons. Line arcs are closed to polygons simply by connecting the last point with the first. Optionally single parts of polylines can be merged into one polygon part if these share start/end vertices.

Parameters

	Name	Type	Identifier	Description	Constraints
Input	Lines	shapes, input	`LINES`	-	-
Output	Polygons	shapes, output	`POLYGONS`	-	-
Options	Rings	boolean	`RINGS`	Only convert closed rings, i.e. first and last line vertex must be identical.	Default: 0
	Create One Single Multipart Polygon	boolean	`SINGLE`	-	Default: 0
	Merge Connected Line Parts	boolean	`MERGE`	Treat single polyline parts as one line if connected, i.e. parts share end/start vertices.	Default: 0
	Line Parts as Individual Polygons	boolean	`SPLIT`	If checked polyline parts become individual polygons. Applies only if single multipart polygon output is unchecked.	Default: 0
