Hugin calculates and saves only data inside the crop area. This is
stored in OpenEXR as data window as written in the spec.

So there are different ways to interpret the window sizes: 
Luminance HDR, Gimp, Picture, Hugin using the data window size.
And darktable shows the display window size...

So I don't see darktable as reference either...

Title:
  dataWindow and displayWindow look swapped in generated OpenEXR files

Status in Hugin:
  Opinion

Bug description:
  When exporting a high dynamic range image with a crop as an OpenEXR
  file, the cropped dimensions end up as the dataWindow and the canvas
  size as the displayWindow, which seems like it’s the wrong way around.
  When imported back into darktable, the image has a black border on the
  left and at the top.

  Export settings: https://i.imgur.com/TFmA6zP.png (also attached)

  exrheader output:

      dataWindow (type box2i): (51 78) - (5292 3991)
      displayWindow (type box2i): (0 0) - (5345 4070)

  This happens on intermediary remapped files too, not just the final
  merged output.
