| # RS_Contains |
| |
| Introduction: Returns true if the geometry or raster on the left side contains the geometry or raster on the right side. |
| The convex hull of the raster is considered in the test. |
| |
|  |
| |
| The rules for testing spatial relationship is the same as `RS_Intersects`. |
| |
| Format: |
| |
| `RS_Contains(raster: Raster, geom: Geometry)` |
| |
| `RS_Contains(geom: Geometry, raster: Raster)` |
| |
| `RS_Contains(raster0: Raster, raster1: Raster)` |
| |
| Return type: `Boolean` |
| |
| Since: `v1.5.0` |
| |
| SQL Example |
| |
| ```sql |
| SELECT RS_Contains(RS_MakeEmptyRaster(1, 20, 20, 2, 22, 1), ST_GeomFromWKT('POLYGON ((5 5, 5 10, 10 10, 10 5, 5 5))')) rast_geom, |
| RS_Contains(RS_MakeEmptyRaster(1, 20, 20, 2, 22, 1), RS_MakeEmptyRaster(1, 10, 10, 2, 22, 1)) rast_rast |
| ``` |
| |
| Output: |
| |
