allowEdit in Camera plugin

I want to upload picture by writing some text on it before saving the image.
There is one option in Camera plugin to edit images i.e. “allowEdit”.But it is not allowing me to edit / annotate image (no option is coming to perform this) when I am taking image in my iOS device (iPad). Is there any other option to do this in ionic.

I am using the following code to take picture.

      '
      let option: CameraOptions = {
      quality: 100,
      targetWidth: 900,
      targetHeight: 600,
      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      saveToPhotoAlbum: false,
      allowEdit: true,
      sourceType: 1
      // saveToPhotoAlbum: false
    }

    this.camera.getPicture(option).then((imageURI) => {

    }); 
    '

no there is no such option …allow edit only allow you to …resize image size …if you want to write on image …use ionic overlay …or use canvas…by using canvas you set u r image to canvas…and then draw on it

thanks and regards
