this.cropperSettings.noFileInput = true;
this.data = {};
}

fileChangeListener($event) {
var image:any = new Image();
var file:File = $event.target.files[0];
var myReader:FileReader = new FileReader();
var that = this;
myReader.onloadend = function (loadEvent:any) {
image.src = loadEvent.target.result;
that.cropper.setImage(image);

};

myReader.readAsDataURL(file);
