## <a name="filerobot_integration"></a>Filerobot Integration

Upload the image in your Filerobot storage container, edit it in the Image Editor and upload the result.
Deliver lightning fast over CDN.

The example of Image Editor configuration using Filerobot service can be found
[here](https://github.com/scaleflex/filerobot-image-editor/tree/master/examples/js-with-filerobot).

[Learn more about Filerobot](https://www.filerobot.com/en/home)

## <a name="cloudimage_integration"></a>Cloudimage Integration

Point the Image Editor to your origin image URL, edit it and deliver the result lightning fast over the Cloudimage image CDN.
Limited to the Cloudimage inline transformation features.

The example of Image Editor configuration using the Cloudimage service can be found
[here](https://github.com/scaleflex/filerobot-image-editor/tree/master/examples/js-with-cloudimage).

[Learn more about Cloudimage](https://www.cloudimage.io/en/home)

## <a name="sealing"></a>Cloudimage URL params sealing

When using Cloudimage along with the Filerobot Image Editor (config.processWithCloudimage: true), additional capabilities are available. One such example is the URL parameter sealing.
URL parameter sealing offers you a mechanism of encoding some or all of the URL parameters (watermarks, resizing, filters, etc.). This way, you are protecting your origin images so they cannot be delivered without the respective transformations.
When sealing is configured, you will see two extra URL parameters: ci_seal (calculated hash of the protected query string) and ci_eqs (encrypted data).

### <a name="sealing"></a>Configuration for sealing:

### `filerobot.token`: string

**default**: ''

The token for which URL sealing is configured and activated.

### `filerobot.version`: string

**default**: ''

URL sealing is available from v7.

### `imageSealing.enabled`: bool

**default**: false

### `imageSealing.salt`: string

**default**: ''

The salt string is set upon configuration and is used for the encryption.

### `imageSealing.char_count`: number

**default**: 10

Calculated hash (URL ci_seal parameter) length.

### `imageSealing.include_params`: string[] | null

**default**: null

URL parameters to be sealed. By default (when it's null), all parameters will be sealed. Alternatively, you can set a list of parameters, for example: ['wat_url']. This way, you can freely append additional transformations to the URL (the sealed parameters cannot be overwritten).

### <a name="sealing-configuration-example"></a>Example:
```
config = {
  filerobot: {
    token: 'your-sealing-token',
    version: 'v7',
  },
  imageSealing: {
    enabled: true,
    salt: 'some-salt-str',
    char_count: 10,
    include_params: ['wat', 'wat_url', 'wat_opacity', 'wat_scale', 'wat_pad', 'wat_gravity'],
  },
}
```
