<Ngx-NgxPolygonDraw [src]="<linkToImg>" (created)="created($event)"></Ngx-NgxPolygonDraw>
To create points, just click on the image, they will be connected by lines.
When you're done, do the Right Click and the event created will be emitted and the array of points coordinates will be returned.
[{x: 248.09375, y: 111}, {x: 194.09375, y: 179}, {x: 221.09375, y: 235}, {x: 366.09375, y: 255}]
You can access components methods to track clicks one by one with @ViewChild.
clearCanvas() - method allows you to delete existing points
undo() - method allows you to undo action
You also can check whether the polygon is complete (boolean), its perimeter(array of objects).
