 * @name OpenALPR
 * @description
 * This Cordova plugin adds support for the OpenALPR (Automatic License Plate Recognition) library, which provides support for retrieving the license plate from a picture.
 *
 * @usage
 * ```typescript
 * import { OpenALPR, OpenALPROptions, OpenALPRResult } from '@ionic-native/openalpr';
 *
 *
 * constructor(private openALPR: OpenALPR) { }
 *
 * const scanOptions: OpenALPROptions = {
 *    country: this.openALPR.Country.EU,
 *    amount: 3
 * }
 *
 * // To get imageData, you can use the @ionic-native/camera module for example. It works with DestinationType.FILE_URI and DATA_URL
 *
 * this.openALPR.scan(imageData, scanOptions)
 *   .then((res: [OpenALPRResult]) => console.log(res))
 *   .catch((error: Error) => console.error(error));
 *
 * ```
