## Parameters

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

<ParamField body="x" type="Double">
  The X coordinate (longitude).
</ParamField>

<ParamField body="y" type="Double">
  The Y coordinate (latitude).
</ParamField>

<ParamField body="point" type="Geometry">
  The point value.
</ParamField>

## Return type

<ResponseField type="Integer">
  An integer value.
</ResponseField>

## Examples

```sql theme={"system"}
SELECT RS_WorldToRasterCoordX(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), -53, 51) from rasters;
```

```

```

```sql theme={"system"}
SELECT RS_WorldToRasterCoordX(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), ST_GeomFromText('POINT (-53 51)')) from rasters;
```

```

```

<Tip>
  For non-skewed rasters, you can provide any value for latitude and the intended value of world longitude, to get the desired answer
