Follow-up Comment #3, bug #42107 (project octave):
The problem is that the colors are being inverted. Rnew = 1 - Rold, Gnew = 1
- Gold, Bnew = 1 - Bold. Interestingly, this problem does not occur for
indexed images. The following code works.
img = imread ("rainbow.jpg");
[img2, map] = rgb2ind (img);
imshow (img2, map);
print -djpg test.jpg
