使用angualr4如何使用ngx-image-cropper和裁纸器x1，y1和x2，y2位置获取图像文件的实际宽度和大小

Question

我正在尝试使用带有angular4的ngx-image-cropper获取原始图像的大小，宽度和高度，以及如何获取裁剪图像的左上角，左下角，右上角，右下角坐标。

im not sure if its this what you want but i got the current widht,height, x1, y1 setting the [cropper] input attribute

<image-cropper
      [imageChangedEvent]="imageChangedEvent"
      [maintainAspectRatio]="true"
      [aspectRatio]="2 / 1"
      [resizeToWidth]="192"
      [cropper] =" coordinates" //this get the current coordinates
      format="png"
      (imageCropped)="imageCropped($event)"
      (imageLoaded)="imageLoaded($event)"
      (loadImageFailed)="loadImageFailed()"
  ></image-cropper>

and in the .ts file you create a coordinate object, in this case the object name is coordinates

export class ImageHolderComponent implements OnInit {

  coordinates = {x:0} // object that saves the crop coordinates
}
