Hi, a rookie to this forum, I would be very interested to know if it is possible for GIMP to distort/flatten an image along a horizon by pure vertical shifting of pixel columns, in a way that would make the thick red horizon in the lower half of this image https://img.aapg.org/Portals/0/PackFlash...lor=5cadb8 flat (horizontal), and all other parts of the image moved up or down accordingly, keeping all vertical distances equal?
In other words, is it possible to e.g. draw a curved path along the thick red horizon in the linked image, affix it to the image; then make the path horizontal (without stretching it horizontally) and have the image vertically flattened along/adjusted to such a datum accordingly? The resulting image would, obviously, have curved or jagged top and bottom edges..
Kind regards,
Tor
