Details:
Try:
monoimg(:,:,1) = logical(ones (128));
% All logical one should be white
graphics_toolkit fltk
figure(1)
imshow(monoimg)
% Not black
graphics_toolkit gnuplot
figure(2)
imshow(monoimg)
This looks like a bug related to the gnuplot rgb range change (0 to 255 is the
new default range) similar to the bug identified in
http://savannah.gnu.org/bugs/?52599 . Perhaps all that need be done is to
send {0,255} to gnuplot rather than {0,1}.
