[Octave-bug-tracker] [bug #41851] ind2rgb values outside range of colour map

[Guillaume]

Follow-up Comment #10, bug #41851 (project octave):

Thanks Rik, works fine for me with the warning below being displayed for
values < 1.

if (isfloat (x) && ! isindex (x))
  warning (["Octave:" caller ":invalid-idx-img"],
           [caller ": Indexed image contains colors outside of colormap."]);
endif
