Follow-up Comment #10, bug #45565 (project octave):
Mike Miller solution works for me:
$ gm identify foo-8.bmp
foo-8.bmp BMP 256x100+0+0 PseudoClass 256c 8-bit 26.1Ki 0.000u 0:01
$ octave
octave> img = uint8 (ones (100, 1) .* [0:255]);
octave> map = gray(256);
octave> imwrite (img, map, "foo-octave.bmp");
octave> exit
$ gm identify foo-octave.bmp
foo-octave.bmp BMP 256x100+0+0 PseudoClass 256c 8-bit 51.2Ki 0.000u 0:01
