Maybe not so difficult, and not needing PIL or Pillow. If you import an image into a frame at a 100% scaling (1.0 as far as getImageScale() is concerned), then you find that the DPI is 72. So if you find that the X-scale (for example) is 0.21, then dividing 72.0/0.21 will give you the DPI: 342.9 (rounded).
