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 |
