geos.GEOSClipByRect ⇒ GEOSGeometry ⏏
Intersection optimized for a rectangular clipping polygon. Supposed to be faster than using GEOSIntersection(). Not guaranteed to return valid results.
Kind: global property of geos
Returns: GEOSGeometry - The clipped geometry or NULL on exception Caller is responsible for freeing with GEOSGeom_destroy().
| Param | Type | Description |
|---|---|---|
| g | GEOSGeometry | The input geometry to be clipped |
| xmin | number | Left bound of clipping rectangle |
| ymin | number | Lower bound of clipping rectangle |
| xmax | number | Right bound of clipping rectangle |
| ymax | number | Upper bound of clipping rectangle |
