Ionic / Typescript Example Angular 2 Service

This is an example service that uses ionic-native's built in camera and the cordova-plugin-crop to created a cropped version of the image and return the file path.

import { Injectable } from '@angular/core';
import { Platform } from 'ionic-angular';
import { Camera } from 'ionic-native';
 
declare var plugins: any;
 
@Injectable()
export class CameraService {
 
  public options: any = {
        allowEdit: true,
        sourceType: Camera.PictureSourceType.SAVEDPHOTOALBUM,
        mediaType: Camera.MediaType.ALLMEDIA,
        destinationType: Camera.DestinationType.FILE_URI
  }
  
  constructor(public platform: Platform) {}
 
  // Return a promise to catch errors while loading image 
  getMedia(): Promise<any> {
    return new Promise((resolve, reject) => {
      // Get Image from ionic-native's built in camera plugin 
      Camera.getPicture(this.options).then((fileUri) => {
        // Crop Image, on android this returns something like, '/storage/emulated/0/Android/...' 
        // Only giving an android example as ionic-native camera has built in cropping ability 
        if (this.platform.is('android') {
          // Modify fileUri format, may not always be necessary 
          fileUri = 'file://' + fileUri;
          const options = { quality: 100 };
          /* Using cordova-plugin-crop starts here */
          plugins.crop.promise(fileUri, options).then( (path) => {
            // path looks like 'file:///storage/emulated/0/Android/data/com.foo.bar/cache/1477008080626-cropped.jpg?1477008106566' 
            console.log('Cropped Image Path!: ' + path);
            // Do whatever you want with new path such as read in a file 
            // Here we resolve the path to finish, but normally you would now want to read in the file 
            resolve(path);
          }).catch( (error) => {
            reject(error);
          });
        }
      }).catch((error) => {
        reject(error);
      }
    });
  }
  
}
