geos.GEOSProject ⇒ number ⏏
Returns the distance of a point projected on a line from the origin of the line.
Kind: Exported member
Returns: number - The distance of the projected point along the line, or -1 on exception.
See: https://libgeos.org/doxygen/geos__c_8h.html#a557
| Param | Type | Description |
|---|---|---|
| line | number | The GEOSGeometry pointer of the lineal geometry. |
| point | number | The GEOSGeometry pointer of the point geometry. |
geos.GEOSProjectNormalized ⇒ number ⏏
Returns the distance of point p projected on line g from the origin of g, which must be a lineal geometry. The distance is normalized to the length of g.
Kind: Exported member
Returns: number - The normalized distance of p projected on g, or -1 on error.
See: https://docs.rs/geos-sys/1.0.13/geos_sys/fn.GEOSProjectNormalized.html
| Param | Type | Description |
|---|---|---|
| g | number | A pointer to a GEOSGeometry object representing a lineal geometry. |
| p | number | A pointer to a GEOSGeometry object representing a point. |
geos.GEOSProjectNormalized_r ⇒ number ⏏
Returns the distance of point p projected on line g from the origin of g, which must be a lineal geometry. The distance is normalized to the length of g. This is a thread-safe variant of GEOSProjectNormalized that takes a GEOS context handle as an argument.
Kind: Exported member
Returns: number - The normalized distance of p projected on g, or -1 on error.
See: https://github.com/libgeos/geos/blob/main/capi/geos_c.h.in
| Param | Type | Description |
|---|---|---|
| handle | number | A pointer to a GEOSContextHandle_t object. |
| g | number | A pointer to a GEOSGeometry object representing a lineal geometry. |
| p | number | A pointer to a GEOSGeometry object representing a point. |
geos.GEOSProject_r ⇒ number ⏏
Returns the distance of a point projected on a line from the origin of the line, using a reentrant context.
Kind: Exported member
Returns: number - The distance of the projected point along the line, or -1 on exception.
See: https://libgeos.org/doxygen/geos__c_8h_source.html#l00557
| Param | Type | Description |
|---|---|---|
| handle | number | A pointer to the GEOS context handle. |
| line | number | The GEOSGeometry pointer of the lineal geometry. |
| point | number | The GEOSGeometry pointer of the point geometry. |
