geos.GEOSOffsetCurve ⇒ GEOSGeometry ⏏
Generates offset curve line(s) for a geometry. Handles all geometry types as input.
Kind: global property of geos
Returns: GEOSGeometry - The offset geometry. Returns NULL on exception. Caller is responsible for freeing with GEOSGeom_destroy().
| Param | Type | Description |
|---|---|---|
| g | GEOSGeometry | The linear geometry to offset from |
| width | number | Distance to offset from the curve. Negative for a right-side offset. Positive for a left-side offset. |
| quadsegs | number | Number of segments per quadrant |
| joinStyle | number | See GEOSBufJoinStyles |
| mitreLimit | number | See GEOSBufferParams_setMitreLimit |
