    final imageFile = File('path/to/image');
    // Edges that are respective for the original image size.
    final originalImageEdges = await EdgeDetector().detectEdges(imageFile);
    if (originalImageEdges == null) return;

    final topLeft = originalImageEdges.topLeft; // Offset(x,y).
    final topRight = originalImageEdges.topRight; // Offset(x,y).
    final bottomRight = originalImageEdges.bottomRight; // Offset(x,y).
    final bottomLeft = originalImageEdges.bottomLeft; // Offset(x,y).
    final all = originalImageEdges.values; // [topLeft, topRight, bottomRight, bottomLeft].

    // Edges that are respective for the rendered image widget size.
    final widgetEdges = await originalImageEdges.toWidgetEdges(
      imageKey: _imageKey,
      originalImageFile: imageFile,
    );
