Follow-up Comment #4, bug #45779 (project octave):

One correction to the results below.

imwrite (randi ([0 255], 100, 100, 3, "uint8"), "without-map-rgb.bmp")

correctly produces a 24bit RGB image.


imwrite (randi ([0 255], 100, 100, 3, "uint8"), "without-map-gray.bmp")

incorrectly generates a 24bit RGB image where all three channels seem to have
the same information.
