# Bounds

## fitBounds

takes bounds and opt as arguments and sets the center of the map with the given parameter. bounds parameter is a JSON object with two intercardinal directions (sw and ne), with latitude and longitude (lat, lng) respectively.

```javascript
mapInstance.fitBounds(bounds, opt);
```

### Parameter

| Required Parameter | Description                                                                                     | Type |
| ------------------ | ----------------------------------------------------------------------------------------------- | ---- |
| bounds             | Center these bounds in the viewport and use the highest zoom level up to and including the map. | JSON |

| Optional Parameter | Description                                                                                   | Type    |
| ------------------ | --------------------------------------------------------------------------------------------- | ------- |
| padding            | The amount of padding in pixels to add to the given bounds.                                   | Numeric |
| linear             | If true, the map transitions using Map#easeTo. If false, the map transitions using Map#flyTo. | Bool    |
| maxZoom            | The maximum zoom level to allow when the map view transitions to the specified bounds.        | Numeric |

### Example

```javascript
let bounds = {
        sw: {lat: 37.457464, lng: 126.899302},
        ne: {lat: 37.645804, lng: 127.161728}
}

let opt = {
    padding: {
           top: 5,
           bottom: 5,
           right: 15,
           left: 15
    },
    linear: true,         // true for “easeTo” false for “flyTo”
    maxZoom: 10
}

let opt2 = {
    padding: 10            // 10 for top, bottom, right, and left.
}

mapInstance.fitBounds(fit, opt);
mapInstance2.fitBounds(fit, opt2);
```

## getBounds

Retrieves the bounds attribute set in 'fitBounds()'

```javascript
mapInstance.getBounds();
```

### Return

Intercardinal coordinates (ne, sw) with latitude and longitude

```javascript
mapInstance.getBounds();
return : {
        ne : {lat: 37.645804, lng: 127.161728}
        sw : {lat: 37.457464, lng: 126.899302}
}
```
