geos.GEOSInterpolate ⇒ GEOSGeometry ⏏
Measuring from start of line, return point that is distance the start. Line parameter must be a LineString. The returned point is not guaranteed to intersect the line due to limitations of floating point calculations.
Kind: global property of geos
Returns: GEOSGeometry - The point GEOSGeometry that is distance from the start of line. Caller takes ownership of returned geometry.
| Param | Type | Description |
|---|---|---|
| line | GEOSGeometry | linear target of projection |
| d | number | distance from start of line to created point |
geos.GEOSInterpolateNormalized ⇒ GEOSGeometry ⏏
Measuring from start of line, return point that is a proportion the start. Line parameter must be a LineString.
Kind: global property of geos
Returns: GEOSGeometry - The point GEOSGeometry that is distance from the start of line. Caller takes ownership of returned geometry.
| Param | Type | Description |
|---|---|---|
| line | GEOSGeometry | linear target of projection |
| proportion | number | The proportion from the start of line to created point |
geos.GEOSInterpolateNormalized_r ⇒ GEOSGeometry ⏏
Measuring from start of line, return point that is a proportion the start. Line parameter must be a LineString.
