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`.

## Signatures

```sql theme={"system"}
RS_Contains(raster: Raster, geom: Geometry)
```

```sql theme={"system"}
RS_Contains(geom: Geometry, raster: Raster)
```

```sql theme={"system"}
RS_Contains(raster0: Raster, raster1: Raster)
```

## Parameters

<ParamField body="raster0" type="Raster">
  The raster0 value.
</ParamField>

<ParamField body="raster1" type="Raster">
  The raster1 value.
</ParamField>

<ParamField body="raster" type="Raster">
  The input raster.
</ParamField>

<ParamField body="geom" type="Geometry">
  The input geometry.
</ParamField>

## Return type

<ResponseField type="Boolean">
  Returns `true` or `false`.
</ResponseField>

## Example

```sql theme={"system"}
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
```
