Hey everyone,

yesterday I tried to integrate this:

> <https://github.com/OHIF/react-vtkjs-viewport/blob/master/examples/VTKCrosshairsExample.js>

with my project, but unfortunately got an error

Steps I took to integrate:

1. downloaded this file, and imported it into one of my project files
2. checked the versions on the examples and matched them with my project

I tried to narrow the code to figure out which part of it was causing the error, and saw that those lines:

```
import {
  View2D,
  getImageData,
  loadImageData,
  vtkInteractorStyleMPRCrosshairs,
  vtkSVGCrosshairsWidget,
} from '@vtk-viewport';

```

were causing the error.

Any help would be highly appreciated
