Customizing Image cropper

Replacing component file input:

<div class="file-upload">
  <span class="text">upload</span>
  <input type="file" id="custom-input">
</div>

<br>
<span class="result rounded">
  <img>
</span>

data:any;

@ViewChild('cropper')
cropper:ImageCropperComponent;

constructor() {
    this.cropperSettings = new CropperSettings();
    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);
}
