_______________________________________________________
Details:
After applying the patch for bug #52589 (have not tried without the patch)
gnuplot shows a shaded image when using imshow on a png image containing only
primary saturated colours.
THe following works well with the attached file
close all; graphics_toolkit fltk;
imshow(double(imread('path2017/legend.png')));
If you try using gnuplot rather than fltk, you see a shaded image.
By the way, note that I force the output of imread to double because of bug
#49140.
