# ee.Geometry.LinearRing.difference

Returns the result of subtracting the 'right' geometry from the 'left' geometry.

<br />

| Usage | Returns |
|---|---|
| `LinearRing.difference(right, *maxError*, *proj*)` | Geometry |

| Argument | Type | Details |
|---|---|---|
| this: `left` | Geometry | The geometry used as the left operand of the operation. |
| `right` | Geometry | The geometry used as the right operand of the operation. |
| `maxError` | ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
| `proj` | Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |

## Examples

### Code Editor (JavaScript)

```javascript
// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the difference method to the LinearRing object.
var linearRingDifference = linearRing.difference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('linearRing.difference(...) =', linearRingDifference);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
             {'color': 'black'},
             'Geometry [black]: linearRing');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
Map.addLayer(linearRingDifference,
             {'color': 'red'},
             'Result [red]: linearRing.difference');
```
Python setup

See the [Python Environment](https://developers.google.com/earth-engine/guides/python_install) page for information on the Python API and using
`geemap` for interactive development.

```python
import ee
import geemap.core as geemap
```
