Follow-up Comment #15, bug #51769 (project octave):
Thanks for the checks. I fixed the issue with multi-channel images and added a
corresponding test, for 1 to 3 channels and for "nearest", "bilinear" and
"bicubic". It just checks that resizing a multi-channel image is equivalent to
resizing the channels separately.
Regarding the gray level difference: The tests have a tolerance of 1. It might
be a rounding issue (tie break), I forgot. Should we investigate this or use
tolerances only at tie breaks in the test?
