})
export class AppModule { }

import { Camera,CameraOptions } from ‘@ionic-native/camera/ngx‘;

constructor(private camera: Camera) { }

...


const options: CameraOptions = {
  quality: 100,desTinationType: this.camera.DesTinationType.FILE_URI,encodingType: this.camera.EncodingType.JPEG,mediaType: this.camera.MediaType.PICTURE
}

this.camera.getPicture(options).then((imageData) => {
 // imageData is either a base64 encoded String or a file URI
 // If it‘s base64 (DATA_URL):
 let base64Image = ‘data:image/jpeg;base64,‘ + imageData;
},(err) => {
 // Handle error
});
